Mongolia is launching a large project to build solar power plants with a total capacity of 110 MW and battery energy storage systems. These installations are aimed at optimizing renewable energy production and enhancing the stability of the power grid. The project is designed to accumulate excess energy generated during the daytime for use during peak evening hours and to smooth out fluctuations caused by weather changes.

The Government of Mongolia has announced a tender for the construction of five solar power plants, which will include energy storage systems with a capacity of 52 MW/188 MWh. The Ministry of Energy has already identified land plots for all the facilities put out to tender, three of which are located in the west of the country, and two in the east.

The construction plans include solar power plants in various aimags. In Bayankhongor, a 10 MW installation will be built with a battery storage of 10 MW/20 MWh, while in Sukhbaatar, a similar station will also be 10 MW but with a 2 MW/8 MWh battery. In Bayan-Ölgii and Dornod, power plants with capacities of 20 MW and 30 MW respectively will be installed, each with storage systems of 10 MW/40 MWh. The largest solar power plant with a capacity of 40 MW and a battery of 20 MW/80 MWh is planned for the Uvs aimag. All complexes will be connected to existing substations in these regions.

The projects will utilize the independent power producer (IPP) model. Once interest in the project is announced, the government will conduct a competitive selection of developers who will be responsible for the design, financing, construction, and operation of the power plants. The request for proposals (RfP) is expected to be published in the second half of the year, but it is still unclear whether auctions will be held for each project separately or collectively.

Developers will be able to submit their applications for participation until August 16.
