Rising data-center demand is pushing up electricity costs across multiple generation sources, with solar and onshore wind also climbing more than 10% to multi-year highs.
U.S. natural gas power costs reached $90/MWh (dollars per megawatt-hour) in 2026, marking the highest level in at least 17 years. The move reflects a broader rise in electricity costs as data-center demand increases strain on power markets. Solar and onshore wind prices were also up more than 10%, reaching multi-year highs at the same time. The development points to tightening power supply economics across the generation mix rather than pressure confined to a single fuel source.
