NV Energy to end Tahoe power by May 2027, hitting Microsoft data centers
NV Energy will end wholesale electricity deliveries to the Lake Tahoe region after May 2027, jeopardizing power supply for Microsoft’s expanding data centers in northern Nevada’s Tahoe-Reno corridor. Liberty Utilities relies on NV Energy for 75% of its supply and must secure alternative sources in a highly competitive market.
1. NV Energy to end Tahoe power supply after May 2027
NV Energy has informed the local utility that it will stop wholesale electricity deliveries to the Lake Tahoe region after May 2027 as part of a long-planned transition. This ends a supply relationship dating back to 2009 under agreements renewed most recently at the close of 2025.
2. Data center demand surges in northern Nevada
Northern Nevada’s Tahoe-Reno Industrial Center has attracted major tech firms including Microsoft, Google and Apple, with projected data center load growth of up to 5,900 megawatts by 2033. Data centers already accounted for roughly 20% of Nevada’s electricity demand in 2024, potentially rising to 35% by 2033.
3. Impact on Microsoft’s Tahoe-Reno facilities
Microsoft’s expanding data center operations in the region rely on Liberty Utilities, which sources 75% of its power from NV Energy. The scheduled cutoff exposes Microsoft to potential power cost increases or delays unless alternative supplies are secured.
4. Replacement sourcing and procurement challenges
Liberty Utilities must launch a formal procurement process in summer 2026 to replace up to 75% of its supply under “extremely competitive” market conditions. Building new transmission lines to California’s grid would cost hundreds of millions of dollars, complicating the search for viable alternatives.
