Regulation on the Procedures and Principles Regarding the Use and Leasing of Water Surfaces for the Establishment of Floating Solar Power Plants Published

The Regulation on the Procedures and Principles Regarding the Use and Leasing of Water Surface in the Establishment of Floating Solar Power Plants (Regulation) entered into force after being published in the Official Gazette dated 10.12.2025 and numbered 33103. The Regulation includes comprehensive regulations on the establishment of floating solar power plants on dam lakes, artificial lakes and canal surfaces and the use and leasing of these floating solar power plants.

The applications are made for:

1. Floating SPP facilities to be established for the purpose of meeting the energy requirements of irrigation facilities,
2. Floating SPP facilities to be established as auxiliary source energy generation facilities based on energy generation facilities whose main source is hydraulic,
3. Floating SPP facilities to be established within the scope of renewable energy resource area,
4. Floating SPP facilities to be established by municipalities or their affiliated organizations within municipal boundaries.

A lease agreement is concluded with the General Directorate of State Hydraulic Works (DSI) for the installation of Floating SPP. The lease fee is calculated by formula considering the installed capacity, average annual energy production value, Floating SPP island areas, market clearing price and Floating SPP site area. A three-year term guarantee in the amount determined and announced by DSI according to the facility's installed capacity is submitted to DSI and is updated every three years.

Project approval, construction supervision and acceptance procedures for Floating SPP facilities are carried out in accordance with the existing regulatory provisions applied in terrestrial SPP projects. Reservoir operation plans prepared by DSI must be complied with.

For projects where the Floating Solar Power Plant feasibility report has been approved by DSI or a lease contract has been signed prior to the publication of the Regulation, a feasibility report must be prepared in the format determined in the Regulation within three months.
