Overview
Zagorskaya PSPP is a 1,200 MW hydroelectric pumped-storage power plant in Russia, operated by PJSC RusHydro. It plays a key role in grid stability and peak load management.
Zagorskaya PSPP is a hydroelectric pumped-storage power plant located in the Moscow region of Russia, with an installed capacity of 1,200 MW. Operated by PJSC RusHydro, it is one of the largest pumped-storage facilities in the country, providing essential grid balancing and peak power generation services. The plant utilizes pumped-storage technology, which allows it to store energy by pumping water to an upper reservoir during low demand and releasing it to generate electricity during peak periods. This technology enhances grid reliability and integrates variable renewable sources. Russia's hydroelectric sector is regulated under national environmental standards, with oversight from the Ministry of Energy and Rostechnadzor. As a pumped-storage facility, Zagorskaya PSPP contributes to the stability of the Moscow power system, supporting the region's industrial and residential electricity needs. Its operation reduces reliance on fossil-fuel peaking plants, offering environmental benefits through lower emissions and improved grid efficiency.
Environmental context
Hydroelectric pumped-storage plants like Zagorskaya PSPP have a low carbon footprint during operation but can affect local aquatic ecosystems through water level fluctuations and habitat alteration. The facility's location in the Moscow region, a densely populated area, requires careful management of water resources and noise. Its role in displacing fossil-fuel peaking plants provides net environmental benefits by reducing greenhouse gas emissions and air pollutants.
