Washington Advances Data Center Regulation Bill

In late February 2026 Microsoft testified against Washington's HB 2515, with senior director Lauren McDonald urging the Senate Ways & Means Committee to amend the bill. HB 2515, passed by the House, would require data centers to shield ratepayers, report energy and water use, forecast loads, and reach 80% clean power by 2030 and 100% by 2045; the Senate is now deliberating.
