Solar container lithium battery power station in Lithuania

How many battery energy storage systems are there in Lithuania?

The four battery energy storage systems (BESS), 50MW/50MWh each, have been handed over by Fluence and are now providing services to Litgrid, the transmission system operator (TSO) in Lithuania. They followed a smaller, 1MW/1MWh pilot project to test the use case back in 2021.

Which power plant provides energy storage in Lithuania?

Kruonis Pumped Storage Plant provides energy storage, averaging electrical demand throughout the day. The pumped storage plant has a capacity of 900 MW (4 units, 225 MW each). Kaunas Hydroelectric Power Plant has 100 MW of capacity and supplies about 3% of the electrical demand in Lithuania.

How much balancing capacity does Lithuania need?

So the whole region would need around 1GW of balancing capacities but Lithuania alone will need around 700-800MW of capacity for FRR. We have applications to build 800-900MW of storage, and those with a letter of intent (LOI) and bank deposit total around 150MW today.

How does Litgrid use pilot battery storage?

Audrius Baranauskas: We as Litgrid have a 1MW/MWh pilot battery storage as a transmission system asset and we use it to implement the grid booster concept in three different ways. The battery can react to the frequency and react instantly, faster than FCR provided by traditional generators. Another way is to react to the voltage.
