The U.S. Energy Information Administration (EIA) reports a significant rise in the share of solar generation that includes co-located battery storage. As of September 2026, over 16% of new utility-scale solar capacity added this year is co-located with operable battery storage, up from 2% in 2017. Plans for the last quarter of 2026 suggest this could increase to 19%. The trend is expected to continue, with projections indicating over 30% for 2027 and 2028. This co-location allows operators to manage solar electricity output based on wholesale prices, maximizing value in fluctuating markets.
