Battery storage, read in context

Market analysis, regulatory updates and strategic perspectives on battery energy storage across the Nordics, Baltics and wider Europe. Two reads a week, no fluff.

Regulation

Bulgaria Selected 13,700 MWh of Batteries for Grants. Its Minister Puts First-Round Payouts at About 6 Per Cent.

RESTORE 2, the second round of Bulgaria's recovery-plan storage programme, reaches its latest permitted build date on 31 July. In June the energy minister put payments under the first round at about 6 per cent and under the second at nothing.

Batteries Pay to Use the Grid Twice. Europe Is Unwinding That in 2026

France cuts storage grid fees in August, Ireland follows in October and the EU principle is already law. The Nordics and Baltics have not moved, so the grid-fee line stays full. Here is what that does to a BESS model.

Romania Just Made Grid Access an Auction. Batteries Have to Win It

Romania has EUR 150 million in battery grants and a queue of 81 GW behind 1,407 permits. From 2026 it stops handing out grid access first-come and auctions it. The money was never the hard part. The grid is.

The Baltic Battery Window Is Open. The Clock Is Running.

Fifteen months after the Baltics unplugged from Russia and began running their own grid frequency, the reserve markets they stood up in weeks are paying like scarcity. They are scarce. Here is how long that lasts and what to underwrite on.
