Wood Mackenzie's latest global LCOE report lands a clean verdict: four-hour battery energy storage is now cheaper to build than open-cycle gas turbines in all 43 markets where both technologies were modeled. This is not a regional anomaly or a subsidy artifact. It is a structural crossover driven by manufacturing scale on one side and supply-chain constraint on the other. The numbers are stark across every region. In the Middle East and Africa, where utility-scale solar already sets the pace at $37/MWh, four-hour storage LCOE is forecast to drop 33% to $80/MWh by 2035. China anchors the global floor at more than 55% below the rest of Asia Pacific's average of $134/MWh, a gap built on vertically integrated domestic supply chains. Saudi Arabia and the UAE are on track to push solar below $20/MWh by 2033. Single-axis tracker solar is already the lowest-cost new-build technology in 43 of 48 modeled markets. The gas side of the ledger is moving in the wrong direction. Investment in gas generation capacity is entering a supply deficit cycle through the late 2030s, driven partly by data center load growth. Gas turbine shortages and fuel price volatility are pushing peaking costs up precisely as battery costs fall. In Europe, levelized carbon costs are projected to surpass fuel costs by 2030, making fossil generation the most expensive in any modeled region. North America is the outlier under stress. Tariffs, anti-dumping actions, and Section 232 import restrictions are creating near-term headwinds for solar, with module prices expected to rise roughly 5% annually through 2030. Residential and commercial solar faces steeper exposure — module prices forecast up 6% in 2027 and 14% in 2028. Storage retains a tax-credit cushion but faces a cost spike when ITC credits phase out from 2038. The U.S. is essentially testing whether policy friction can slow a global cost curve. The answer so far is: partially, temporarily, and at a price. Latin America and Asia Pacific are riding the manufacturing tailwind. Chinese turbine OEMs are compressing onshore wind costs across Southeast Asia, Egypt, and Morocco, with capacity factors of 40-45%. Latin American storage LCOE is forecast to fall 42% by 2060. Regional disparities remain wide — Asia Pacific solar costs vary by 200% between cheapest and most expensive markets, widening to 250% by 2030 — but the direction is uniform. The report's most consequential finding is not about any single technology but about the combination. As Wood Mackenzie's Ahmed Jameel Abdullah put it, storage and solar together are redefining power system economics. Long-term contracted renewables increasingly set the ceiling on power costs, not the floor. The economic case for new gas peaking capacity is closing across every modeled region. This is the kind of structural shift that rewrites infrastructure planning for decades. The question is no longer whether batteries beat gas peakers on cost — they do, everywhere — but how fast incumbent systems, regulatory frameworks, and trade policies adapt to a reality the cost curves have already decided.
