PHOTOVOLTAIC POWER PLANTS IN CROATIA
In Republic of Croatia exists legislative frame for investments in power plants on renewable sources of energy according to Cratian governments by law for getting a status of privileged electricity producer and tariff system for electricity production from renewable sources of energy and cogeneration.
The photovoltaic systems are classified depending privileged energy prices in three categories:
1) 10 kW and less
2) 10,1 to 30 kW
3) over 30 kW
In reality that means PV s instalation up to 30 kW on family houses, warehouses and other factories, and over 30 kW installation on the ground (on grid).
Comparison shows following economic investment criteria:
a) SHARE OF INVESTMENT PVs ON THE ROOFS
85% facilities and installation (90% modules, 10% converters)
Investment per 1 kW+vat=4,50 EURO app.
b) SHARE OF INVESTMENT PVs FOR BIG SOLAR POWER PLANTS
60% facilities and installation (80% modules, 10% converters, 10% installation)
10% project preparing, projects and studies
15% transformer station and connection
10% carriers construction and infrastructure
5% land,buying or renting with license building
Investment per 1 kW+vat=4 EURO app.
The small PVs on the roofs are the most effective in the Croatian regions with insolation under 1200kWp/h (northern parts of Croatia).On the coast and particulary hinterland of Dalmatia and the islands all kinds of PVs are effective because of the insolation much over 1200kWp/h including bigger photovoltaic systems.Particulary interesting are the special care areas because of the lower interest rates ( 4% Croatian Bank for Reconstruction and Development ), and later smaller taxes.More information on
Low costs of servicing and line connection with the investor and facility supplier are a guarantee of safety and reliablity for the business.
The recent growth of interest to invest in new power plants in Croatia resulted from implementation of laws and regulations that stimulate electricity production from renewable energy sources ( RES ).
Most of these plants tend to connect to the distribution network.
Distribution system operator HEP - ODS ltd.( DSO ) in cooperation with other entities;
HEP - TRANSMISSION SYSTEM OPERATOR ltd, Ministry of Economy, Labour and Enterpreneurship, The Croatian Energy Market Operator continues working on the adjustments and simplifying necessary procedures for connecting power plant to DSO network, as well as on defining the necessary technical requirements on connection of production unit to the power distribution network.
This document gives a procedure for a potential electric energy producer to go with DSO starting the first contact and finishing with a final connecting to the DSOs network. The document gives the actual experiance and current status of inplementation of given procedure; connecting the power plants to power distribution network.
