Estonia-based energy company Eesti Energia plans to install what will be its home country’s first grid-scale battery energy storage system (BESS), of 25 MW/50 MWh in size. The state-owned group said last week it has launched a procurement to find a supplier for the facility this summer. The process will be open internationally.
The proposed facility is planned to be installed in Ida-Viru county in Estonia’s northeast. It will provide one hour of storage capacity, during which it will release electricity equal to the consumption of around 150,000 households. It will enable the storage of solar power produced by 2,500 residential installations for over two hours.
The concept will potentially be used as a viable solution both in Estonia and the company’s other retail markets. Eesti Energia aims to cease producing electricity from oil shale by 2030 and transition exclusively to renewable electricity production.

Last summer, it unveiled a plan to build an up to 225-MW pumped-storage hydropower plant in Ida-Viru County and secured state funding a few months later. Choose your newsletter by Renewables Now.
