First solar power plant with a tracker system launched in Chechnya

07 october 2024

A new solar power plant with a system tracking the Sun’s movement has been commissioned in the Achkhoy-Martanovsky district of the Chechen Republic. The system will allow a 9.2 MW plant to increase electricity generation by 20% - 25% compared to conventional installations.

The project was financed by the Hevel Group of companies which invested more than 1 billion rubles in the power plant. It is expected that the plant will generate about 13 million kWh of electricity per year, which will reduce carbon dioxide emissions by 4,500 tons.

The power plant is located on an area of about 18 hectares near the village of Samashki. About 30,000 solar modules manufactured in Russia have been installed at the station, and over 90 kilometers of cable lines have been laid. The heterostructural modules used can work effectively in all weather conditions and at extreme temperatures.

This is the second solar power plant in the republic. The first was the Naurskaya plant with a capacity of 5 MW, according to nia.eco.
