The energy ministry is considering yet another revision to its investment support plan for standalone batteries that would reduce support offered for batteries with two-hour durations to 50,000 euros per MWh and maintain support offered for batteries with four-hour durations at 100,000 euros per MWh, the objective being to ensure that batteries with a total capacity of 1,700 MW end up receiving investment support, energypress sources have informed.

An additional battery capacity of between 400 and 500 MW is expected to become available for investment support as a result of the revisions.

The ministry is planning a forthcoming RES auction, next month, to offer investment support for two-hour standalone batteries representing a total capacity of 175 MW.

It will be followed by an auction exclusively supporting four-hour batteries, planned to be installed at some of the country’s former lignite-dependent areas, and, further ahead, an additional session auctioning off any remaining capacity.

A preceding auction, earlier this year, had offered RES projects energy-storage investment support of 200,000 euros per MW, now being reduced to widen the support program’s coverage.
