Four-hour BESS undercuts gas peakers in 43 global markets

Four-hour battery energy storage systems (BESS) have become cheaper than open-cycle gas turbines in 43 global markets, driven by advancing technology and manufacturing scale, although the US faces near-term cost challenges due to tariffs and import restrictions. Federal tax credits in the US help offset these costs, and growing power demand from data centers is increasing pressure on grid capacity, reinforcing the economic advantage of renewables plus storage over gas peakers internationally.
