Hydrogen gas nuclei on the sun form helium nuclei through fusion, and a large amount of energy is released during this time. A small portion of the energy generated as a result of the reactions occurring in the sun reaches the earth by radiation method. The basic principle of the system is to collect this radiation through solar panels or panels called solar panels and convert it into electrical energy through photons.

Today, with industrialization and a growing population, the need for energy is increasing exponentially. The decrease in resources such as oil and natural gas and the increasing cost of generating energy from these resources has encouraged the use of the sun that does not emit harmful gases and pollution. We can group solar power plants under 3 main chapter, taking into account the regulations and practices in Turkey.

Solar Power Plants Without License

Before 09.05.2019, Solar Power Plants Without License are the applications with an installed power below 1 MW. There is an obligation to show consumption at a rate of 1/33. It is possible to sell it to the distribution network in accordance with the principles of electricity balancing. The state’s purchase guarantee for unlicensed projects is 10 years, and it is said that it will be reviewed according to market conditions in the next 10 years.

There is no obligation for solar radiation measurement. If there is sufficient electrical power capacity confirmed by TEIAS (Turkish Electricity Transmission Corporation), it can be applied to the relevant electrical distribution company.

The Solar power plant application is done by preparing the necessary documents according to the capacity status of the relevant electrical distribution companies every month, and the feedbacks of the relevant distribution company can be obtained within the following two months. Environmental Impact Assessment (EIA) is not required for these facilities. Unlicensed Solar Power Plants up to 1 MW, established as a land application in Turkey had a special value in the sector until the beginning of 2018 with government incentives and 10-year purchase guarantees. However, with the end of the incentives given to facilities below 1MW and the increase in average distribution and operating system costs, the amortization period of the investment costs of these facilities has increased significantly.

After 09.05.2019 some changes were made in the regulation with the Presidential Decree No. 1044. As a result of these changes, the upper limit for unlicensed GES installations was determined as 5MW. Monthly offsetting was introduced. The mandate was a balance between electricity generation and consumption. Rooftop installation is mandatory (except for public ones). Organized Industrial Zones permit and project approval was established. It is estimated that the unlicensed Solar Power Plants installation will accelerate again in the coming period.

Licensed Solar Power Plants

They are plants with an installed power of more than 1 MW. There is no obligation to show consumption, and the generated electricity can be directly given to the grid. The license term for licensed projects is 49 years, and it is also possible to sell the generated energy under market conditions. Before the application process of the project file, a minimum of 6 months solar statistics and real meteorological solar radiation are required.

The licensed SPP starts with the project file application process established by EMRA (Energy Market Regulatory Authority) in line with the strategies of the Ministry of Energy. This application process takes 3 to 4 days and a certain capacity is determined for the year in which the application is submitted. In the process after the submission and examination of the project files by EMRA, the project is also examined by TEİAŞ based on the capacity of the transformer substation and according to the application process criteria.

Applications over 10 MW are done for medium or high voltage transmission lines level. It is not necessary to supply incoming feeder for solar power plants below 10 MW. Environmental Impact Assessment is required for licensed Solar Power Plants. Within the scope of many large and small Renewable Energy Resource Area projects, companies participate in the competition in line with the capacities determined by the state and the winning company makes an investment. These facilities are established as land applications.
