Energy efficiency talks



Financing aspects are dominating ongoing talks on the energy efficiency directive, but member states are keeping their hands firmly on their wallets, EurActiv has learned.
As negotiations over the energy efficiency directive reopen under the Danish EU Presidency, discussions are  focusing heavily on financing aspects.
However, several options floated by the European Parliament to break the deadlock already look like non-starters, EurActiv was told.
And opposition by some EU states is making a binding 20% energy efficiency target impossible, said Martin Lidegaard, Danish minister for climate, energy and building as he was speaking to a group of Brussels-based journalists in Copenhagen. 

Bendt Bendtsen, a Danish member of Parliament who is following the dossier for the European People's Party (EPP) told EurActiv that funding mechanisms currently contemplated by Parliament will be blocked by the EU Council of Ministers, which represents the EU's 27 member states.
“The provision on ear-marking of financing, such as national energy efficiency funds will not be part of the final piece of legislation,” Bendtsen said.
“It is generally quite difficult to convince member states to earmark funds," explained Bendtsen, adding that "this has even been the case before the crisis emerged”.
“I feel that the council has a hard job ahead, the ball is really on their table,” he said.
Danes revive talks
Both the European Commission and Parliament were forced to change their position on the proposed energy efficiency directive in order to accommodate the Council's views. Member sates first refused to sign up to binding targets on energy savings, which prompted the Commission to propose binding "measures" instead.
Now, the Council does not want binding measures either, Bendtsen said, “unless the targets are measured differently or there are opt-outs or something else”.
The Danish presidency was expected to meet the Council’s energy working group yesterday (10 January) for the first time since it took over the EU's rotating presidency on 1 January. The Danes are hoping to piggy-back on discussions over the EU's energy roadmap to 2050 in order to re-launch the stalled talks on the directive.
Funding to be discussed as part of the 2014-2020 EU budget
But financing issues are more likely to be addressed in wider talks over the EU budget for 2014-2020, the Multi-Annual Financial Framework (MFF), which covers areas such as research and regional funding.
The funding aspect of the directive “has to be seen in the full picture of the European Regional Development Fund and 'Horizon 2020' [research agenda], but should not necessarily be a part of the directive,” an EU official told EurActiv.
Member states are avoiding signing up to a specific wording on financing issues in the text of the directive, as they do not want to prejudge the ongoing negotiations over the EU’s budget for the 2014-2020 period, EurActiv understands.
The upcoming months will see “tough talks” on the proposed directive, with “a large majority of the European Parliament” wanting binding financial facilities in place to fund the energy efficiency measures and member states being reluctant to allocating further money.
The talks are "like a poker game" where governments keep their cards close to their chests, said Claude Turmes, a Green MEP from Luxembourg who is spearheading talks for the European Parliament.
Claire Roumet of Cecodhas, a federation promoting social housing in Europe, said financing issues were crucial as renovation work in homes help bring energy bills down for the poorest. “[The EED] is looking at more than just EU finance. Tapping money for energy efficiency is not touched fully by the MFF, because it does not take into consideration all alternative types of funding,” Roumet told EurActiv.
Roumet was also adamant that binding measures were necessary. ​“If there is an obligation without specific measures, it will never be complied with," she said.
March vote in Parliament
Meanwhile, the European Parliament's committee on industry, research and energy (ITRE), which has the lead on the dossier, has pushed back its vote on the draft text from 24 January to 28 February. A full parliamentary vote is expected to take place late March.
The delay can be explained by the huge number of amendments, with more than 1,800 changes proposed to the draft energy efficiency bill.
“The number of amendments shows just how important this directive is,” said Claude Turmes MEP. The industry committee aims to integrate all those into 60-70 compromise amendments for the final vote of the Parliament.
“We are entering the eye of the storm, we are trying to build alliances with friendly governments,” Turmes told EurActiv.
On financing aspects, he said he was optimistic: “We are very much still in the negotiations, it is still very probable that we will have a text on this issue of financing in the directive".
The Green MEP said that the Parliament's insistence on having financial facilities included in the text of the directive gives the Assembly “visibility” and allows it “to have a tough discussion on financing” with member states.
Targets to stimulate investment
And as financing aspects remain the most difficult part of the negotiation, some are trying to revive an old idea – making the EU's 20% energy efficiency target legally-binding on the member states.
Proponents say a binding target would make it harder for countries to argue against energy efficiency funds, because they would be compelled to allocate some money from the EU budget to meet that objective.
"A way of seeing it is the spine is the target and the flesh is the European budget to add meat to the bone," Sanjeev Kumar of environmental group E3G told EurActiv.
And even if the EU allocates some specific funds for energy efficiency, without targets investments might remain scarce, efficiency advocates argue.
The European Commission’s last report on how the 2007-2013 budget was spent says that "certain energy and environmental investments are not progressing  as expected" and this must be redressed by the member states and regions.
"The direction for 10-20 years is vital so that you can cast these investments over a longer time," Kumar said. "It gives people certainty that their efforts will not be reversed," he added.
Claude Turmes, the Green MEP, agrees. “The more binding the target , the less risky the investment,” he said. “A clear target gives a bigger incentive to kick start investment. More flexibility and joint targets would make the energy efficiency directive easier to be agreed on,” Roumet added.
The  Danish presidency, described as “ambitious, but realistic”, its aim to finalise the so-called 'trialogue’ talks between the European Commission, Council and Parliament on the energy efficiency directive during the first six months of 2012.

How do you calculate battery capacity in amp-hours (Ah) at different “C” rates?

  

How do you calculate battery capacity in amp-hours (Ah) at different “C” rates?

For instance, I know that a battery with a capacity of 200 Ah at C/20 has a different capacity at C/100.
When you size a PV system with a battery bank of, say, 800 Ah, how do you tell what C-rate the battery bank is using?
C-rates are also called “hourly rates,” and are based on the length of time of discharge. A C/20 rate means that battery capacity is calculated based on completely discharging it over the course of 20 hours. So, if you have a 1,000 amp-hour battery bank, charging or discharging at 50 amps would be a C/20 rate (1,000 Ah ÷ 50 A = 20 hrs.).
The informal solar industry standard for comparing deep-cycle battery capacity is at the C/20 rate, because it approximates the 24-hour discharge period of most off-grid systems. Many battery manufacturers’ data sheets also provide capacity information for C/5 and C/100 rates, which are useful in other industries.
It is possible to calculate battery capacity at any given C-rate, if you know Peukert’s exponent for the battery. Peukert was a German scientist who derived the formula for the relationship between battery capacity and discharge rate. Battery manufacturers do not typically provide Peukert data on their spec sheets, but it may be available by contacting them.
It = C × [C ÷ (I × H)] k – 1; where
H = rated discharge time in hours;
C = rated capacity at that discharge rate;
I = actual discharge current in amps;
k = Peukert exponent
It = effective capacity at the discharge rate “I”
Most flooded lead-acid batteries have a Peukert exponent between 1.2 and 1.4, while most absorbed glass mat (AGM) batteries are between 1.05 and 1.2—but keep in mind that these figures will increase as the batteries age. Peukert’s exponent for a given battery can also be calculated if the manufacturer provides you with the capacity ratings at two different discharge rates. That math is complicated, but there’s a helpful spreadsheet (and detailed information on applying Peukert’s law) at www.smartgauge.co.uk/peukert_depth.html
A typical renewable energy system will be charging or discharging at different C-rates throughout the course of any given 24 hours. With a battery monitoring system that logs data to a computer spreadsheet, it’s possible to calculate the C-rate at any given instant. And though it seems strange, your usable battery bank capacity is continuously changing.
Fortunately for the typical home RE system owner, discharge C-rates are, on average, quite low. Consider a 48 V battery bank of 1,000 Ah in a system that’s designed to provide 10 kWh of backup energy per day. Those 10 kWh equal 208 Ah. This divided by 24 hours equals 8.7 A. That’s a daily average rate of C/115 (1,000 ÷ 8.7), far slower than the C/20 rate used for comparison when selecting batteries. It’s true that large loads that are used during those 24 hours will increase Peukert effects and reduce usable battery capacity, but this example is also figured with no solar input. On sunny days, the C-rate of discharge will be even slower.
Folks working with electric vehicles must pay closer attention to Peukert’s law. A typical EV’s battery bank has much lower capacity than one in a typical solar home, since both battery weight and bulk must be minimized in vehicles. Also, EV motors use battery energy at very high rates—under some conditions, the battery might be fully discharged in less than an hour.
For solar energy applications, simply using proper system sizing guidelines such as online spreadsheets or consultation with your local RE dealer will keep the batteries’ C-rates reasonable, usually much better than C/20. Peukert’s exponent will only raise its ugly head if you drastically undersize your battery bank for your loads, or in specialized applications like electric vehicles.

Key Information related to energy efficiency



Energy efficiency

Key Information related to energy efficiency

Faced with great energy challenges relating to competitiveness, climate change and security of energy supply, Europe has launched several initiatives to do more with less energy. This not only includes important pieces of legislation such as the Energy Performance of Buildings Directive and the Eco-design Directive, but also supporting programmes like Intelligent Energy-Europe, to help implement policies in the field. Overall, the European Union is committed to reducing projected energy use by 20% by 2020. Europe recognises energy efficiency as one of the most powerful and cost-effective tools to produce a secure energy future.

Improvements in energy efficiency can make a real difference! The reduction of fossil fuel use decreases Europe's dependence on foreign energy supplies. The reduction of greenhouse gas emissions limits local air pollution. The expansion of competitiveness and consumer welfare results in significant economic benefits. There are many ways one can save energy and thereby benefit all sectors of the economy.

The mobilisation of all market actors and the launch of energy efficiency measures can greatly contribute to meeting the '3 times 20' targets set at the European and national levels on renewable energy sources, energy efficiency and the reduction of CO2 emissions by 2020. It is estimated that such energy savings would allow Europe to reduce its CO2 emissions by 780 million tonnes and save €100 billion in fuel costs. Local and regional energy actors are already actively contributing to improving energy efficiency in their communities through the introduction of measures, such as the retrofitting of buildings, climate competitions or the provision of incentives for purchasing energy-efficient products. A wealth of experience in this field is available on: CCRES site.

CCRES Home Design Basics




CROATIAN CENTER of RENEWABLE ENERGY SOURCES

CCRES Home Design Basics


Passive solar design can make a home more comfortable in every season. The winter sun can warm a home´s interior, while simple shading and thermal mass strategies can prevent summer overheating.

The home designs on the following pages balance four primary building elements orientation, windows, overhangs, and thermal mass—to optimize use of the sun´s energy. While these elements are found in most conventional homes, the designs included here put the right amount in the right places for maximal efficiency and performance. Most of them also provide ample south-facing roof space to accommodate the addition of solar hot water collectors and solar-electric arrays—part of a whole-house plan for energy efficiency and independence.

Whether you´re having a builder construct your own home from these plans or building for a client, consider these best design bets.More info at: http://solarserdar.blogspot.com

Site Right

In the winter, the sun rises in the southeast, is low in the south sky at midday, and sets in the southwest in the middle latitudes in North America. In the summer, the sun rises in the northeast, is high in the south sky at midday, and sets in the northwest.

In all areas except the southern tip of Florida, choose a home site that receives full southern sun in winter and is unobstructed by trees, other buildings, or hillsides. Besides your own observations about shading during the seasons, site analysis tools can provide a quick, accurate assessment of your proposed building site. You can also use a compass to help find true north and south, but keep in mind that a compass points to magnetic north, which can vary by as much as 25 degrees from true north. This difference is called magnetic declination.

To maximize winter sun and summer shade, orient the home´s south face to within 10 degrees of true south. Even though orienting the house 30 degrees from true south reduces winter solar gain by only 13 percent, the cooling penalty can be greater. Homes facing from 30 to 45 degrees east or west of south may need longer overhangs. This is especially true if the home´s orientation favors the west, because overhangs quickly become much less effective as the hot western sun, low in the sky, strikes the house. In most locations, a slight orientation to the east is desirable to increase winter morning sun and decrease summer afternoon sun.More info at: http://solarserdar.blogspot.com

Proper Window Placement

Heat from the sun entering south-facing windows and doors with glass can provide between 20 and 80 percent of the heat required to keep a house warm in winter. The highest percentages are possible in homes in mild climates and those that are well insulated.

South-facing glass should be at least 5 percent and usually no greater than 12 percent of the conditioned square footage of the house. (For example, a 1,000-square-foot house would have between 50 and 120 square feet of south-facing glazing.) Ideally this should apply separately to each floor of the house. Include only the glazing square footage—do not include window or door frames. For instance, a 30- by 60-inch window (12.5 square feet) might only have 10 square feet of glazing.

Homes with south glass area between 5 and 7 percent are commonly referred to as sun-tempered, and are appropriate for very hot climates such as the southernmost areas of the United States (as a rule, below 35 degrees north latitude, although there are many exceptions based on local climate conditions). If south glass exceeds 7 percent of the floor area, install materials with high thermal mass inside the house, such as concrete or masonry, to moderate interior temperature swings.

Place just enough windows on the north, east, and west walls to balance interior light levels, capture any views, create an attractive house, and allow for natural cooling. But be sparing, because windows placed in these orientations are energy drains in cold months and, in the summer, eastern and western windows let in unwanted hot morning or afternoon sun, unless they are shaded. For balanced lighting and ventilation, place windows on opposite or at least two sides of each room. Limit the use of skylights, which admit too much sun in the summer and are difficult to shade. Instead, install sun tubes (also known as tubular skylights) in interior rooms without windows, which let in some light, but less heat.

Window manufacturers often use "solar" to describe glazing, but usually this is an indication that the glass blocks the sun (has a low solar heat gain coefficient; SHGC) and can be very misleading. For passive solar space heating, south-facing windows should have a high SHGC (at least 0.52) to maximize the amount of the sun´s heat that passes through the glass. A window with a SHGC of 0.33 lets in only 33 percent of the sun´s heat energy. If you can´t find high SHGC windows, a reasonable option is to install clear (uncoated) double-paned glass and use insulated blinds or shutters at night to minimize heat loss. Alternatively, triple-paned clear glass will let in a large amount of sun while limiting heat loss. Some building codes stipulate a maximum SHGC of 0.4, but then allow you to average all of the SHGCs so that windows with higher SHGCs can be used on the home´s south face.More info at: http://solarserdar.blogspot.com

Seek Summertime Shade

Overhangs, awnings, and porches can shade windows in certain seasons and prevent the home from overheating. For cold climates, design overhangs for a long season of full sun striking the south glass. Overhangs should fully shade south-facing windows during the summer months, and allow full sun on windows during the wintertime. For hot climates, design overhangs for a long season of full shade on the south glass. It is fairly simple to achieve full shade on June 21, the summer solstice, when the sun is high. Shading in August becomes more difficult, since increasing the overhang depth will also shade the window in April, when more solar gain may be desirable for heating. This is where a slight easterly rotation of the house can help.

South window overhangs should be sized for the height of the windows, wall height, and the construction detail of where the roof meets the wall. West and east windows require much longer overhangs, and these windows are best shaded by other methods, such as porches or trees.

During the late summer and early fall months, it may be necessary to close blinds or curtains, and pay more attention to passive cooling strategies like opening windows when the temperature drops below 70°F, and closing up the house in the morning, before the day begins to warm. Likewise, in late spring, there may be a few cool days where more heat is desired than is entering the partially shaded south windows. Conserving the heat that does enter by using insulated curtains on the windows can be highly effective.More info at: http://solarserdar.blogspot.com

Make It Massive

Materials with high thermal mass, such as brick, stone, ceramic tile, and concrete, absorb direct solar gain in the winter and indirect heat during the summer. Although it is best to locate thermal mass in the path of direct sunlight, other mass in contact with the material that receives direct solar gain can serve the same function. Including thermal mass is especially important for homes with glass above 7 percent of the home´s square footage. Locate the mass as close to south-facing windows as possible. For each square foot of glass above 7 percent, add:

• 5.5 sq. ft. of mass in floors that receive direct sunlight
• 8.3 sq. ft. of mass in walls and ceilings in the same room
• 40 sq. ft. of mass in floors that don´t receive direct solar gain

Strive for a minimum of 2 inches (and a maximum of 4 inches) of thermal mass. Less than 2 inches does not store sufficient heat and more than 4 inches (unless it is an 8-inch wall with both sides exposed) can absorb so much heat that it will be too slowly released. The maximum amount of floor mass area that should be used is 1.5 times the south-facing window area, since the sun cannot hit large areas all at once.

For cost effectiveness, use concrete, concrete masonry, and earthen plasters as thermal mass. Slab-on-grade construction, where a concrete floor is poured over insulation, can economically combine the foundation with a heat-absorbing floor. ICF (insulating concrete form) foundations, which sandwich concrete between expanded polystyrene foam panels, are very compatible with cold-climate slabs, even when the upper part of the house is framed with studs. ICFs are an excellent option for the main house walls also. Studies have shown that their combination of mass and insulation helps temper interior temperature swings, even though the foam somewhat isolates the concrete (mass) from the living areas.

Interior heat-absorbing walls, made of concrete block, stone, or brick, can also serve to absorb solar heat. Masonry walls are commonly incorporated into fireplace or wood heater surrounds. With the creative use of decorative concrete block, or coverings (veneers) of stone, brick, stucco, plaster, or tile, heat-storing walls can become effective passive heating elements, as well as beautiful accent walls and focal points in a home.More info at: http://solarserdar.blogspot.com




Daylighting

Daylighting is the art and science of using natural light to illuminate indoor spaces. It saves energy, and can make living and working areas more attractive and comfortable. Daylighting in homes is typically accomplished using windows, translucent doors, skylights, light pipes (tubular skylights), and clerestories. A well-designed daylit home on a sunny lot can get by without any electric lighting between dawn and dusk.

Daylight is sunlight that is direct or reflected. Sunshine provides us with vitamin D, and also combats seasonal affective disorder, or winter depression. Natural light doesn´t change the character of colors the way artificial lights can and, with its subtly changing intensity, daylight is much more interesting. It can make us feel more connected to nature and supports our natural biological rhythms, which contribute to restful sleep.

Using sunlight in your home can decrease heating and cooling loads through passive solar design techniques, as well as eliminate most lighting needs during the day. Its use has been proven, in commercial settings and schools, to decrease absenteeism and increase productivity and test scores. Also, people who work in naturally lit buildings report a sense of well-being.

Designing a daylit home can be very simple. In most regions, provide a long south wall of windows and locate the main living spaces along the south side to take advantage of direct solar gain in the wintertime. In the summer, adequately deep, fixed overhangs will block heat gain but still allow indirect light to enter the windows.

First, arrange rooms based on your preferences. Morning people tend to like their bedrooms located in the southeast corner of a home. Kitchen and breakfast rooms may compete for that corner. Night folks usually don´t mind a bedroom on the west; by the time they retire, the room will have cooled off. Artists, especially painters, usually locate their studios on a home´s north side to take advantage of the uniformity of northern light.

Next, select your daylighting strategies. Start with windows for almost every room. Consider light, heat gain, ventilation, views, aesthetics, and emergency exits when making your choices of window sizes and types. Add a clerestory for overhead, private light, increased ventilation, and desirable heat gain. A small operable skylight with a flared light well can provide sky-gazing opportunities and overhead light, with privacy and increased ventilation. Light pipes are a great choice for naturally lighting small interior spaces and dark corners.

Daylight is extremely variable in intensity and duration, changing throughout the day and year. These characteristics can make it challenging to deliver consistent lighting. Light sensors can control artificial light sources, on dimmers, to maintain minimum light levels.

Glare is a potential problem for many systems. Controlling reflected sun by using light shelves (interior "overhangs") or wide windowsills is effective, and using sheer fabrics to filter incoming light can also help.

Living with natural light helps us feel less isolated from nature, and being indoors seems more like a temporary condition, rather than a permanent sentence. With thoughtful daylighting design incorporated into your home, you´ll find that from dawn to dusk, the best things in light are free.More info at: http://solarserdar.blogspot.com

CCRES - Changing Energy Wasting Habits Costs Nothing



CROATIAN CENTER of RENEWABLE ENERGY SOURCES


Simple Ways to Save Energy and Help Others Do the Same


CCRES - Changing Energy Wasting Habits Costs Nothing

Here are some ideas on how you can save energy at home without spending a dime. These conservation ideas merely require a bit of thought and a slight touch of the hand. The hard part is getting rid of energy-expensive habits and teaching yourself the new ones. But with a little effort the new habits will soon be second nature. The simple guidelines to follow are: turn it off, close it, and set it lower…so, here are 5 ideas:

Turn off the lights when leaving a room. Turning off just one 60-watt incandescent bulb can save about $15 per year. (Of course, replacing your incandescent bulbs with CFLs or LEDs will cut your lighting electric bill by up to 85%!)
While brushing your teeth, stop running the water. Although running water does not use energy per se, heating the water does so avoid wasting hot water in particular.
Turn off power strips or unplug appliances - especially when leaving for vacation. Most appliances when plugged in still draw power when turned off - this is called phantom power. So, stop the ghosts from costing you money when you're away!
Close the blinds to block direct sunlight in the summer and keep the cold out during winter nights. These measures help to stabilize the temperature indoors and reduce the burden on your home heating and cooling systems, which typically use about 50% of the energy in your home.
Turn down the temperature control thermostat on your water heater to 120 degrees F. For each 10 degrees F reduction in water temperature, you can save about 3-5% in home energy costs. Although most water heater thermostats are set at 140 degrees F, most households have plenty of hot water when set to 120. Reducing your water termperature can also extend the life of your water heater and pipes by slowing mineral buildup and corrosion.

HELP YOUR COMMUNITY


From waking up early to put in a first load of laundry to working all day and driving the mom taxi all afternoon, most women have little time to think about volunteering for community projects. But busy schedules do not mean we have to write off community involvement completely. In thirty minutes or less, anyone can make a difference in the community.

Check out the following ideas for ways to help your community in the midst of your everyday activities.



Take a garbage bag while walking through the neighborhood. Pick up any litter along the way. As a by-product, you can get some exercise built into your day.
Shop with locally owned businesses, saving time and money. Many locally owned businesses offer services like free gift-wrapping and delivery. And a percentage of your sales taxes go directly to the local community.
Find positive aspects of your community share with other people. A positive image encourages residents to shop locally, increases the chance new businesses will open in the area and promotes growth.
Attend a local festival or other event. Many have free admission and activities. Most festivals are actually fundraisers for non-profit organizations who make their money through sponsorships. Since sponsors look at attendance numbers to decide how much to give, your family can add to the number and help increase what businesses give next year.
Write a letter to local elected officials encouraging them for making good decisions for the community. People work harder when they know they are appreciated. And elected officials seldom hear enough encouraging words.
Put a potted plant on your front porch. When your home looks spruced up, it makes the whole neighborhood and the community to look better as well.
Take left over dinner to an elderly neighbor. If you have a family of four, cook enough dinner for five one night and deliver a plate to the widow next door. Your delivery helps you to get to know your neighbors better. And police promote knowing your neighbors as the best way to fight neighborhood crime.
Look for opportunities to give in your community. Many schools collect items, such as like canned foods, old coats, toys and eyeglasses, for less fortunate families.
Vote. The Presidential election comes around only once every four years. Check out the candidates for local and state elections.
Encourage your employer to sponsor local events, join a civic organization or allow employees to volunteer during work hours. Many businesses have volunteer programs to reward employees for volunteering. Local news media often cover large volunteer events and having employee representation gives businesses extra publicity.
By doing our part to contribute to the community, we add people to our circle of influence and gain opportunities to build relationships with our neighbours. We also demonstrate what it means to be a good citizen to our children.

DOE officially launched the EcoCar2 competition on April 13 and named the sixteen university teams that were selected to participate. EcoCar2: Plugging into the Future is an educational partnership between General Motors and DOE to help prepare future engineers for opportunities in clean energy and advanced vehicle industries.

EcoCAR 2 is a unique three-year collegiate engineering competition that challenges teams to reduce the environmental impact of an existing vehicle without compromising performance, safety, or consumer acceptability. The program's combination of cutting-edge engineering practices, hands-on experience, and knowledge sharing in a competitive and team-oriented environment gives participating students a head start toward future job success. Participants will go on to make contributions that will help keep the North American automotive industry competitive in the global market place, which is increasingly adopting fuel-efficient designs.

EcoCAR2 includes both new teams and veterans to the advanced vehicle technology competitions. These teams will explore a variety of power train architectures and follow a real-world engineering regimen modeled after GM's Global Vehicle Development Process (GVDP). Each EcoCar2 team will use a Chevrolet Malibu, donated by General Motors, as the integration platform for their advanced vehicle design. See the DOE press release and the EcoCAR Challenge website.

DOE Rolls Out Program to Promote Electric Vehicles
DOE is taking new steps to speed up the deployment of electric vehicles (EV), it announced on April 19. These efforts include making available $5 million in new funding for community-based efforts to deploy EV infrastructure and charging stations. DOE is also forming a partnership with Google Inc. and more than 80 EV stakeholders to help consumers find charging stations nationwide. The goal is to reduce U.S. dependence on foreign oil, saving consumers money and helping meet the administration's goal of 1 million advanced technology vehicles on the road by 2015.

Local governments and private companies will partner to apply for the $5 million in funding to help accelerate installation of EV charging stations. Communities will work to develop plans and strategies for EV deployment, update their EV permitting processes, develop incentive programs, or launch other initiatives. See the Funding Opportunity Announcement on FedConnect. Applications are due June 13.

In a related effort, DOE's National Renewable Energy Laboratory (NREL) is joining with Google Inc. and various industry leaders to provide consumers with consistent, up-to-date information about the EV charging stations in communities nationwide. Using Google Maps, this new collaboration between NREL and partners will coordinate an online network of all U.S. charging stations and will serve as the primary data source for GPS and mapping services tracking electric vehicle charging locations. These efforts are supported by the Clean Cities program, a public-private partnership that brings together federal, state, and local governments, the auto industry, private sector fleet operators, and community leaders to help communities make their vehicle fleets more energy efficient. See the DOE press release and Clean Cities website.

DOE Labs Join to Develop Next-Generation Cool Roofs

DOE announced on April 14 that its Oak Ridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) have joined with The Dow Chemical Company as part of a cooperative research and development agreement to research next-generation cool roof technologies. The agreement will support research to increase the energy savings from existing cool roof technologies by more than 50%.

ORNL will partner with LBNL to capitalize on the broad range of cool roof technology experience they bring from their applied research in this field. The research will focus on the development of new solar reflective roof coatings that would increase the energy savings from existing cool roof technologies for new and existing commercial buildings. In partnership with Dow, DOE's national laboratories will work to improve the ability of roof coatings to continue reflecting sunlight after years of exposure to the elements. This includes developing technologies that improve the long-term resistance of these materials to dirt build-up and microbial growth. The goal of the cooperative research partnership is to design and commercialize the next generation of cool roof components that could significantly reduce the energy consumption of new and existing buildings.

The replacement or resurfacing of conventional roofing materials with improved reflective roof coatings could offer building owners energy savings of up to 25% on air conditioning. Improvements could reduce annual carbon dioxide emissions by 5 metric tons for every 10,000 square feet of commercial building roof area. Commercial buildings in the United States today offer an opportunity to retrofit more than 20 billion square feet of roofing space. A recent study by researchers at LBNL found that using cool roofs and cool pavements in cities around the world could help reduce the demand for air conditioning, cool entire cities, and potentially cancel the heating effect of a year of worldwide carbon dioxide emissions. See the DOE press release and the Building Technologies Program Cool Roof Web page.

California CSP Plant Gets $2.1 Billion DOE Loan Guarantee
DOE announced on April 18 its offer of a conditional commitment for a $2.1 billion loan guarantee to support Units 1 and 2 of the Blythe Solar Power Project, sponsored by Solar Trust of America, LLC. The concentrating solar thermal power plant includes two units with 484 megawatt (MW) of generating capacity. The project will be built adjacent to the City of Blythe in Riverside County, California and is expected to create more than 1,000 construction jobs and approximately 80 operations jobs. The plant is estimated to avoid more than 710,000 tons of carbon dioxide emissions annually, an amount equivalent to the annual greenhouse gas emissions from more than 123,000 vehicles.

Units 1 and 2 of the Blythe project represent the first phase of a larger project that, when completed, will generate 1,000 MW of solar power using parabolic trough technology. Units 1 and 2 will include HelioTrough collectors, which feature a larger, yet simplified design, making them less expensive to build and install, and more efficient than earlier trough technology. The project will be the first concentrating solar power (CSP) parabolic trough plant to use an air-cooled condenser unit, which will decrease water use by nearly 90% compared with a water-cooled CSP facility. The project will sell all its electricity output to Southern California Edison. DOE's Loan Programs Office has issued loan guarantees or offered conditional commitments for loan guarantees totaling more than $21 billion to support 22 clean energy projects across 14 states. See the DOE press release and Loan Programs Office website.

PNNL Study: Algae Could Replace 17% of U.S. Oil Imports
Every day, the United States spends about $1 billion to import foreign oil, money that we could be investing in American energy and the American economy. President Obama recently announced an ambitious but achievable goal of reducing our oil imports by a third by 2025. To meet this goal, we will need to increase our use of homegrown advanced biofuels. On April 13, DOE's Pacific Northwest National Laboratory (PNNL) came out with a new study that shows that 17% of the United States' imported oil for transportation could be replaced with American-grown biofuels from algae.

Developing the next generation of biofuels is an important step towards reducing our dependence on foreign oil and advancing new economic opportunities throughout the country. See the Energy Blog post.

King County, Washington, Is Charging Up Savings
Residents of King County, Washington, are seeing several improvements in their community thanks to a $6.1 million Energy Efficiency and Conservation Block Grant (EECBG). The grant, which is funded by the Recovery Act, has allowed King County to conduct a variety of public and commercial energy efficiency upgrades, including the installation of electric vehicle charging stations, upgrades to its vehicle fleet, and energy improvements to senior housing.

With the help of EECBG funds, the county is helping lead a regional effort to install electric vehicle charging stations at strategic locations across the Puget Sound area. This will allow members of the public to charge their vehicles away from home and extend their trips. The installation project is expected to be finished this summer. According to King County executives, it will allow people who are buying electric vehicles to quickly charge them at the new 240-volt charging stations throughout King County. Additionally, the county is also improving the energy efficiency of its extensive fleet of vehicles by replacing conventionally powered vehicles with gas-electric hybrids. This new fleet will lower vehicle emissions and save 4,800 gallons of gas annually compared to the 20 current fleet vehicles. See the Energy Blog post.

DOE Partners to Test Advanced Energy Technologies for Utilities
DOE's Advanced Research Projects Agency-Energy (ARPA-E) has signed a partnership deal that focuses on the electric power utility industries in the United States and abroad to identify opportunities for testing and deploying ARPA-E funded grid projects. Under a Memorandum of Understanding (MOU) DOE announced on April 14, ARPA-E, Duke Energy, and the nonprofit Electric Power Research Institute (EPRI) will seek to expand cutting-edge smart grid developments, including grid-scale energy storage, power electronics, and energy efficient cooling technologies.

Under the terms of the agreement, ARPA-E will facilitate the exchange of information between ARPA-E-supported projects, EPRI, and Duke Energy, which delivers energy to approximately four million customers in five states. Duke Energy could deploy and test ARPA-E technologies at various power plants or wind farms. The technologies may also be studied either at the company's McAlpine substation, a test bed for renewable, grid storage, and smart grid technologies, or at the company's Envision Center, a smart grid demonstration and testing facility in Erlanger, Kentucky.

EPRI, whose members represent more than 90% of the electricity generated in the United States, will offer test-bed facilities at two of its research facilities in Charlotte, North Carolina and Knoxville, Tennessee. The sites are used for tests on consumer electronics, lightings, smart grid components, heating and cooling systems, and electric vehicle infrastructure requirements. See the DOE press release and the ARPA-E website.

United States and Qatar Sign Clean Energy MOU
DOE and the Qatar Science & Technology Park signed on April 6 a Memorandum of Understanding (MOU) to promote collaboration on the development and deployment of cost-effective and sustainable clean energy technologies. The partners will exchange scientific and technical information and will undertake joint research, development, and deployment initiatives. These actions will help spur energy innovation, create new markets for clean energy, and support economic growth. The MOU builds on the historically strong ties between the two nations.

DOE, principally through the Advanced Research Projects Agency—Energy (ARPA-E) and the Qatar Science & Technology Park, will pursue cooperation in key areas including advanced cooling technologies such as next-generation cooling technologies, systems integration, and building controls; renewable power generation, including coating systems to reduce the effects of weather conditions on photovoltaic systems; and energy storage with an eye toward thermal storage for combined heat and power.

Over the next decade, the partners will work with the private sector to foster scientific exchanges and research on cutting-edge technologies, including using Qatari facilities as test beds for large-scale demonstration of U.S. and Qatari technologies. The data collected from these demonstrations will help further refine the development of these innovative technologies and could provide the partners with new capabilities to meet their respective energy goals for the future. This agreement will also serve to reinforce and complement joint U.S.-Qatar participation in multilateral partnerships to achieve clean energy development and shared climate change goals. See the DOE press release.

Ohio State University Readies for its Encore at the U.S. Department of Energy Solar Decathlon 2011
The Ohio State University Team enCore is getting ramped up for its second run at the Solar Decathlon as part of the U.S. Department of Energy Solar Decathlon 2011 this fall. After placing 10th during the 2009 competition, the team is looking to bring a bigger, tougher and more efficient house to this year's event.

Mark Walter, Associate Professor of Mechanical Engineering, provided an insider's perspective. "Our goals are not too different [compared to 2009]," said Walter, who is also a faculty advisor to the team. "With the additional experience we're looking to reach out to the community and really bringing the best possible product to the Mall." In addition, Walter said enCore is looking to solve sustainable design problems with its original home through better efficiency, tighter construction, and smarter engineering. See the Energy Blog entry.

Interior Approves Cape Wind Offshore Construction and Operations Plan
The U.S. Department of the Interior (DOI) announced on April 19 that the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) has approved a construction and operations plan for the Cape Wind project, an energy project located 4.7 miles offshore in Nantucket Sound. The plan from Cape Wind Associates, LLC suggests that construction of the first U.S. offshore wind farm could begin as early as the fall.

The proposed action, including its size and location, remain substantially the same it was when it was analyzed in the Cape Wind Final Environmental Impact Statement (FEIS), which was published in January 2009. The Cape Wind energy project calls for 130 3.6-megawatt wind turbine generators, each with a maximum blade height of 440 feet, to be arranged in a grid pattern in Nantucket Sound. As part of its evaluation, BOEMRE conducted an environmental assessment to determine whether any significant impacts were not discussed in the 2009 FEIS and concluded that all impacts had been properly examined. See the DOI press release and the BOEMRE Cape Wind Web page.

The future Role of Regional Initiatives promoted by CCRES


CROATIAN CENTER of RENEWABLE ENERGY SOURCES

shares to you


COMMUNICATION FROM THE COMMISSION TO THE EUROPEAN PARLIAMENT AND THE COUNCIL
The future Role of Regional Initiatives

1. CONTEXT
The Regional Initiatives were set up in spring 2006 by the European Regulators' Group for Electricity and Gas (ERGEG), at the request of the European Commission, as an interim step in moving from national electricity and gas markets to a single energy market. Seven electricity regions[1] and three gas regions were created.
The Regional Initiatives (RIs) have been beneficial in providing a forum for regulators, network operators and other stakeholders of neighbouring countries to discuss issues of common interest. Many of the RIs have made progress on a great variety of issues. The electricity regions have mainly focused on congestion management, balancing and transparency. The gas regions have worked on interconnection issues, interoperability, transparency, hubs and security of supply.
Five years after their set up, the Commission considers it useful to evaluate the regional initiatives with a view to assessing whether any modifications to the process, composition or governance could further enhance their effectiveness and contribution to the completion of the internal market. Such a review also fits with the entry into force of the the third internal energy market package (also called Third Energy Package)[2]. The Third Energy Package provides for new tools of European rulemaking through network codes which can be made binding by the Commission using the comitology procedure and changes the institutional architecture with the establishment of the Agency for the Cooperation of Energy Regulators (ACER).The Commission has launched a study on the regional initiatives last year.[3] In parallel, ERGEG has put forward its strategy paper on the role of the regional initiatives[4]. Also some stakeholders published their report on regional cooperation[5] and a Regional Initiatives Conference[6] was organized by the Commission and ERGEG jointly in July.
Based on the conclusions from the studies and debate, the purpose of this Communication is to seek stakeholder's views on possible options for strengthening the effectiveness of the regional initiatives going forward.
Following this communication and depending on the reactions from all interested stakeholders it might trigger, the Commission might launch an initiative based on Article 12.3 of the Electricity and Gas Regulation.[7] According to this Article, the Commission can redefine the geographical area covered by each regional cooperation structure within the context of a broader process of reform of the tasks and governance of Regional Initiatives, to which all actors, Commission, ERGEG, ACER, TSOs, Member States and stakeholders will contribute according to their respective roles and responsibilities.
2. TASKS AND PRIORITIES OF THE REGIONAL INITIATIVES
To a large extent, the Regional Initiatives have so far followed a bottom-up approach whereby each region has set its own priorities. That voluntary approach has had important advantages as it has allowed the regions to focus on their specific problems. For example, the South-South-East gas region has been able to focus on security of supply issues in the wake of the gas supply disruption in January 2009.
It has also allowed pilot testing, whereby solutions can be tested in one region before being implemented elsewhere. For example, solutions found to address problems in the volume coupling between the Danish and German electricity markets has helped create consensus towards the benefits of volume coupling.
Finally, the Regions implemented EU measures with a particular cross-border dimension. The electricity Regions, for instance, worked on implementing the requirements of the congestion management guidelines. The gas North-west region has taken forward the implementation of transparency requirements additional to those defined in Regulation 1775/2005. It is likely that progress in implementation would have been less or slower without the regional approach.
Nevertheless, the voluntary bottom-up approach also has significant drawbacks as recognized from the start[8]. There is an inherent risk of different regions implementing different solutions to similar issues without a clear perspective of integration over time. For example, if each region develops its own common auction office with its own structure, own governance etc., without taking into account convergence with similar structures in other regions, it might endanger the establishment of the internal energy market in the longer run.
The study commissioned by the Commission indicated that a lack of clear terms of reference for the Regional Initiatives, compounded by other factors related inter alia to the governance of the Regional Initiatives, has restricted the ability of the Regional Initiatives to perform the intended bottom-up approach most effectively.
Further policy guidance should therefore be given to the Regional Initiatives along the lines set out in this section.
The overarching principle should be that the Regional Initiatives should only focus on issues where they have a clear added value. Also, taking into account resource constraints, it would be preferable to focus work on a limited set of priorities for which substantial progress can be made.
a. Implementation of the EU acquis including network codes
In the past, the electricity Regional Initiatives dedicated a lot of their time on the implementation of those parts of the acquis requiring cross-border co-ordination (especially cross-border congestion, allocation of cross-border capacity and transparency). Although progress was made on these issues, the work of the Regional Initiatives has not yet resulted in Member States' full compliance with the requirements of Regulation 1228/2003. For this reason, the Commission has launched an infringement exercise in June 2010 requesting twenty Member States to implement and apply Single Market rules without delay.[9] Therefore, a first priority of the Regional Initiatives should be to accelerate the correct implementation of the Second Energy Package[10], i.e. those issues requiring cross-border co-ordination.
In the future, Regional Initiatives might have a role not only in implementing specific provisions of the Third Energy Package itself, but also in implementing legislation based on the Third Energy Package, i.e. new annexes to the Regulations and network codes. When codes will have been adopted via comitology, they will be legally binding and be part of the EU acquis. Since the adoption procedures might however be lengthy, market integration could be promoted if Regional Initiatives start implementing those elements of the network codes which can be expected to remain stable throughout the final stages of the adoption process. The Regional Initiatives should in that case ensure that early implementation does not exclude adjustments later on. Regions could move at different speeds for implementing cross-border aspects of the acquis, insofar of course that all regions meet the dates by which implementation is legally required.
Early implementation by one region might provide a useful test bed on how best to implement new codes, on the time needed to do so and practical hurdles to be overcome. Lessons learned may facilitate and speed up implementation in other regions. The work done so far in the Central-West electricity region on market coupling and in the Central-East electricity region on application of flow based capacity allocation provide good examples in this regard.
In order to avoid that individual regions interpret or apply some provisions of the acquis differently or in a manner which makes future integration with other regions more difficult, ACER should actively monitor the coherent implementation of the codes and other acquis across regions.
Electricity Regional Initiatives should collectively pursue the target of full market coupling across the EU by 2015. Market coupling is a way to foster market integration and will be easier to achieve (and thus quicker) if the countries which are still not using market coupling work together regionally in order to join the EU market coupling.
For gas, the potential role of market coupling in fostering market integration between balancing zones is to be examined in the discussion on a gas market target model. Market coupling should be aimed at by 2015 building on the work of the regulators. Necessary steps in this direction, such as making available firm day ahead capacity and joining exit and entry capacities to form one integral hub-to-hub capacity product are already under way.
For electricity, the Central West Region and the Northern Region have achieved full market coupling in November 2010. Therefore they are at the forefront for the implementation.
However, the way market coupling has to be done at the EU scale should be discussed between Regions for example at the Florence and Madrid Fora. Discussions on the method to be followed to achieve market coupling should be held as soon as possible to avoid technical problems at a later stage.
b. Regional issues: Investments in infrastructure, regional balancing and security of supply
Depending on the specific market conditions of a region, there will be a need for each region to work on issues specific to their region even though such issues may at some point become relevant for other regions as well. Against the background of overall EU energy policy, three issues are to be considered as priorities: regional investments in infrastructure, regional balancing and security of supply.
The Commission has set out its vision on infrastructure development needs in its Communication[11] "Energy infrastructure priorities for 2020 and beyond - A Blueprint for an integrated European energy network", in which it is proposed that the Regional Initiatives could play a key role in identifying infrastructure priorities for their respective regions and in coordinating cross-border investments, typically in new interconnectors. In order to promote cross border investments, investment needs must be clearly established, an appropriate regulatory framework put in place and planning and authorisation issues addressed. ACER plays an important role in facilitating cooperation between regulators on the regulatory aspects of investments decisions. Regional Initiatives can also play a facilitating role as they provide a platform of regulators, TSOs, network users and Member States, with the cooperation of the Commission and ACER, where such issues can be addressed. It should in addition remain possible to address those issues in ad hoc settings outside the scope of the Regional Initiatives where such ad hoc settings are more effective and efficient to promote cross-border investments.
Such investments can also be of particular importance in ensuring security of supply (like investments enabling physical reverse flows for gas). The Regulation on security of gas supply recognizes the need for regional cooperation.
Work on consolidation of balancing zones could be another focus for the Regional Initiatives, depending on the outcome of the discussion on the gas market target model.
Finally, regional cooperation is crucial to enhance the integrity of networks, avoid technical disruptions and blackouts, and address those effectively when they arise with minimum disturbance for users and producers.
c. Pilot testing
For issues which are not yet covered by framework guidelines and network codes, the Regional Initiatives can have an important role as test-bed for new ideas. Eventually this pilot testing might result into an initiative to develop new binding rules, e.g. via new network codes.
Regional pilot projects might be useful for the acceleration of smart grids or cross-border retail market. The European Electricity Grid Initiative set up within the Strategic Energy Technology plan (SET plan) have established a framework under which ENTSO-E has presented a detailed roadmap for the coming years. Regional Initiatives could play a useful role in the implementation of R&D projects (see the Roadmap[12]). Obviously, also on other issues, the regions should be free to engage in pilot testing, depending on specific regional needs.
3. NUMBER OF REGIONS
The electricity regions have been defined in decision 2006/770/EC which amended the congestion management guidelines annexed to Regulation 1228/2003.[13] For gas, the regions have not been formally defined in a binding decision. The gas regions resulted from informal consultation between the Commission, regulators, TSOs and other stakeholders. Practice has shown that the gas regions have managed to achieve progress in the absence of a formal decision establishing the regions and their tasks.
Going forward, two options are possible. The first option is to lay down the composition of the gas regions and their tasks in a formal decision, which has as main advantage that it would avoid discussion and uncertainty and would identify more precisely what is expected from the Member States concerned and their energy stakeholders. The second option is to continue with the informal definition of gas regions, which has as main advantage that it would allow for more flexibility in the composition of the regions over time and their tasks.
Apart from the instrument used to define the regions, the question of their composition arises. The composition of the regions should be determined in function of their tasks. If the aim of the region is to make progress on certain specific priorities, the shape of the region will have to correspond to this.
For electricity, the shape of the existing regions seems to be well suited to address the priorities proposed above and there seems to be no reason to change the composition of the current seven Regions. However, over time when sufficient interconnectors will have been developed to physically link the relevant regions, it may be appropriate to integrate the France-UK-Ireland region with the Central-West region and the Baltic Region with the Northern region.
For gas, there are sound reasons to reshape the current South-South-East region. The study commissioned by the Commission concluded that: "Due to the heterogeneity in size and differing interests of members, the Region (South-South-East) has probably suffered more than others from the drawbacks of the voluntary and cooperative approach which characterises the RIs, that is to say a certain organisational looseness and lack of commitments" . Given the importance of developing new gas infrastructure and new interconnections for the creation of the internal gas market and for security of supply reasons, the Commission proposes to split the current "South, South-East" region into three new regions for gas including the Baltic States and the Nordic countries as follows:
- New Central-South region: IT, AT, SK, SI, HU, RO, BG, EL;
- New Central-East region: DE, PL, CZ, SK, AT;
- New BEMIP region: SE, FI, EE, LV, LT, PL, DE, DK.
Reshaping the region may temporarily disrupt the work of the region on operational issues. However, it would be preferable to get the structure right and to set up new more efficient regions even if it will cost some months, rather than continuing with a structure which appears not suitable to deliver the desired results.
There are also reasons to combine Italy with the current South region (encompassing France and the Iberian Peninsula) since, for instance, this region would be the main entry for the natural gas coming from the north of Africa. The change could have a positive effect on liquidity in this new South Region. As an overlapping country Italy could help ensure the necessary coherence of both southern regions.
In addition to market design issues and the implementation of the acquis, each of the regions should focus on the development of new interconnections.
The format and membership of the current North-West region appears adequate and should not be changed.
It is important to underline that the Regional Initiatives should not exclude other formats of cooperation between TSOs, regulators or Member States, such as the North Seas Countries Offshore Grid Initiative signed by Germany, United Kingdom, France, Denmark, Sweden, the Netherlands, Belgium, Ireland and Luxembourg. The fact that a Member State is part of one region does not prevent it from working together with one or more Member States from another region, insofar as this collaboration does not go against the work of the regions.
Moreover, as also suggested by ERGEG, there are sound reasons for regions to work together on certain topics like e.g. the market coupling between Central-West and Nordic countries. However, such collaboration should not delay the work and deliverables of the regions. If one region gives the "good example", the other regions should aim at following that example (taking into account, if need be, regional specificities).
It is quite likely that the number of regions and their composition will have to be changed again over time. At least from a theoretical viewpoint, the regions will be really successful the day they are not needed anymore.
A regular assessment on the work of the regions and their composition could be done at the occasion of the Florence and Madrid fora.
4. GOVERNANCE ISSUES
1. Structure of each region
The current governance structure of the Regional Initiatives consists of three bodies. In each region, there is the Regional Co-ordination Committee (RCC) which comprises all NRAs of the region. The RCC acts as overall co-ordinator of the tasks facing the Region and provides leadership and strategy. The Implementation Group (IG) consists of NRAs and the main stakeholders. It proposes and commits to undertake concrete actions in response to the priority issues identified at the RCC level. Finally, the Stakeholder Group (SG) consists of all stakeholders.
The study on the Regional Initiatives identified the need for providing more political guidance. Very often, progress in the Regional Initiatives necessitates the involvement of governments in order to change the national legal and regulatory framework and support at the political level, e.g. for cross-border infrastructure projects. The involvement of Member States in the Regional Initiatives should also minimize the risk of a possible multiplication of fora by Member States setting up ad hoc structures outside the Regional Initiatives.
From its entry into force onwards, ACER should play an active role in the Regional Initiatives with a view to ensure effectiveness and consistency in the work of the various regions.
Also the Commission has to provide political guidance given its role to promote the establishment of the internal energy market and given its duty as guardian of the Treaties and the EU acquis. The Commission must be able to make proposals concerning any new tasks that a region should deal with.
The governance of the Regional Initiatives could be strengthened creating a Regional Steering Committee (RSC) including ACER, the Commission as well as the Member States and regulators from the region along the Regional Coordination Committee (RCC) and by enlarging the RCC with ACER and the Commission. The scope of the RSC work would be twofold : to promote and foster cooperation at regional level and provide a high level steer to the work plan for the region to be developed by the RCC in co-ordination with that of ACER, in terms of identifying the implications for political goals relating to security of supply, competitiveness and sustainability; and to boost progress on implementation of the network codes given the new role of the RIs in facilitating implementation and encouraging early implementation of other projects as well as infrastructure development at regional level. The RSC could give a high level impetus to implementation when problems arise. Pure regulatory issues would remain with the RCC.
If appropriate, the RCC and the RSC could invite the TSOs, Power Exchanges or other stakeholders to their meetings, depending on the topics and projects addressed. Such early involvement of the industry would warrant that any strategy and policy decisions are feasible and workable and would address concerns, raised in the Commission's study, that stakeholders currently are involved too late.
To complement the RCC and the RSC, the Implementation Group and the Stakeholder Group should continue to function as today.
2. Governance and coherence across regions
Not only a clear governance structure within regions is important; it is equally important to guarantee the coherence of the work across regions. So far, ERGEG regularly published coherence and convergence reports but it is not clear to what extent the reports were followed up on by the regions.
Coherence of the work of the different regions will in first instance take the form of top-down guidance, which concretely will be provided by the framework guidelines and network codes. These, in turn, will be the translation, as far as electricity is concerned, of the reference model developed by the ERGEG Ad Hoc Advisory Group (AHAG). In addition, there will be a need to verify the coherent application of the network codes across regions. If regions are working on issues which are not treated (yet) in the network codes, there is a need for overall guidance in order not jeopardise the establishment of the internal energy market.
There is no need to create an additional structure to provide for coherence across regions. First, it is a deliberate choice, both in the gas and electricity regions that certain Member States are part of more than one region. These Member States will automatically have the tendency to guarantee coherence in order to avoid implementing different solutions at different borders. Secondly, ACER will have an important role to play in this respect in addition to the policy steer provided by the Commission including through participation in the new RSC. As the Florence and Madrid fora bring together the Commission, ERGEG/ACER, the ENTSOs, NRAs, Member States and trade associations of the industry, they may also offer appropriate platforms to provide policy steer to the regions and monitor coherence. Finally, it might be appropriate that work programmes are developed for the coming year or years. The work programme should be sent to ACER that will assess the coherence of the regions' work programmes with other work programmes, Framework Guidelines and Network Codes. In case of inconsistencies, ACER shall inform the Commission so that the Commission can adopt binding rules for the Work Programme(s) concerned in accordance with the last sentence of Article 7(3) of Regulation EC (No) 713/2009. This review function for ACER should be mentioned in ACER's Work Programme. According to Article 7.3 of the ACER Regulation, one of ACER's tasks is to provide a framework within which national regulators can cooperate. Moreover, ACER must monitor the regional co-operation of TSOs (Article 6.9 of the ACER-Regulation). It thus seems appropriate for ACER, from March 2011 onwards, to take over ERGEG's role of co-ordinating the regional initiatives. As ERGEG is doing today, ACER will need to rely on its member NRAs as driving forces behind the Regional Initiatives.
Moreover, it is important that the work of the Regional Initiatives feeds into the overall work of ACER.
5. THE WAY FORWARD
This Communication has presented an assessment of the performance of Regional Initiatives and their contribution to the creation of an internal market for energy, five years after their establishment. It has set out possible directions for reviewing their role, clarifying their membership and reinforcing their effectiveness. As a staging post towards a truly integrated single energy market, regional initiatives have a key role to play in shaping up the future EU energy policy and in promoting the construction of integrated energy networks fit for the needs of the next decades.
The Commission invites the European Parliament, the Council and all interested parties to express their views on the policy orientations expressed in this paper (by 15 February 2011).
Based on this feedback, the Commission will consider possible legislative or policy initiatives to reinforce cooperation at regional level in the second half of 2011.
