According to a recent report by Fingrid, Finland has connected 261 battery storage systems to its electrical network, totaling 1050 megawatts of power, which surpasses the output of the two nuclear reactors in Loviisa. These battery storage systems help balance the electricity network by storing energy when production is high and electricity prices are low, and then supplying power back to the grid when electricity is scarce and expensive. Jussi Jyrinsalo, responsible for network planning at Fingrid, predicts that the pace of constructing new battery facilities will continue to accelerate, with thousands of megawatts expected to come online within the year.

Despite the promising development, Jyrinsalo has expressed concern regarding the overwhelming number of preliminary connection inquiries, which amount to tens of thousands of megawatts. He suggests that while many projects will not materialize, the sheer volume could potentially clog the entire network if all proposed constructions are realized. This situation highlights an urgent need for careful planning and management of battery storage installations to ensure they contribute effectively to the stability of Finland's electricity system instead of overwhelming it.
