The Energy Agency must on an annual basis in accordance with Article 373 of the Energy Act issue a public call, inviting investors to submit projects for generation units using renewable energy sources or high-efficiency cogeneration for entry into the support scheme. The public calls are carried out by the Energy Agency in a two-stage competition procedure, within the limits of the financial resources defined in the energy accounts of the Republic of Slovenia for each year.

The investors in the submitted projects of RES and CHP generating plants offer the price of electricity generated by the power plant, determined in accordance with the Methodology for determining the support to electricity produced from renewable energy sources and high-efficiency cogeneration of heat and electricity, in accordance with which they will be able to produce electricity commercially. A notified project is included in a competitive selection process if offered price of electricity from a generating unit does not exceed the above reference electricity prices defined as the reference cost of electricity production determined by the Energy Agency prior to the publication of each public call, depending on the technological and economic parameters of each technology and the nominal power of the generating plants. The electricity price offered for electricity produced is the key project selection criteria.
