4-hour battery storage is cheaper to install than gas turbines all across globe

Four-hour battery storage has become cheaper to install than open-cycle gas turbines across all 43 markets analyzed globally, with costs expected to fall further by 2035 due to advancing technology and manufacturing scale. Solar PV with single-axis tracking is now the lowest-cost new-build generation technology in 43 of 48 modeled markets, while battery storage costs are projected to decline significantly as deployment scales. This economic shift is driven by rising gas turbine costs and fuel volatility, combined with expanding battery manufacturing that continues to push storage prices downward.
