Iraq ranked fourth globally with 49.8 gigawatts (GW) of gas-fired capacity in development as the government ramps up efforts to tackle chronic power shortages faced by the OPEC member. Saudi Arabia ranked sixth globally with about 31 GW, driven by the Kingdom’s strategy to replace oil-fired generation with gas. Kuwait ranked eighth, with roughly 21GW of gas-fired capacity under development as the country focuses on upgrading its power fleet to meet rising peak demand. Globally, the U.S. had the most gas-fired power capacity in development at 252 GW in the second half of 2025, representing nearly one-quarter of the world’s total, followed by China at 153GW. While the U.S. leads for total capacity in development, China narrowly leads in capacity under construction (30.9 GW).
