With a handful of leading regions deploying grid-scale storage at a faster rate than ever, what sort of impact are these additions having so far on the problems they are intended to solve?
Wisconsin investor-owned utilities Madison Gas and Electric (MGE) and WEC Energy have received regulatory approval to buy a 200MW solar and 110MW battery energy storage system (BESS) in Kenosha County.
Energy storage could garner a market share of one-third by 2025 for the new, pan-European automatic frequency restoration reserve (aFRR) market, which is set to launch in the middle of this year with France and Germany mutualising capacity first.
