NV Energy to end power supply to Lake Tahoe by May 2027 amid rising data center demand

NV Energy announced it will stop providing power to Liberty Utilities for the Lake Tahoe region after May 2027, affecting about 49,000 residents served by Liberty Utilities around the lake ^{[1, 2]}. Liberty currently obtains roughly 75% of its power from NV Energy and the remaining 25% from its own solar facilities ^{[1, 2]}.

The decision comes amid a surge in power demand driven by rapid data center development in Northern Nevada. NV Energy's 2024 Integrated Resource Plan projects 12 data center projects could add 5,900 megawatts of new demand by 2033 ^{[1, 2]}. Major companies like Google, Apple, and Microsoft are building or planning data centers in the region, one of the fastest-growing data-center corridors in the US ^[1].

Liberty Utilities’ grid lies within NV Energy’s balancing authority, connects at 38 points, and depends entirely on Nevada transmission lines. This arrangement creates regulatory complexity for continuing power supply ^[1].

NV Energy denies that data centers are the sole or main reason for ending power supply. The utility said the termination is part of a long-term transition predating the recent AI boom and that capacity needs are driven by broader factors ^[2]. However, some local stakeholders see the data center expansion as a key driver. Danielle Hughes said, "It’s like we don’t exist," reflecting concerns of residents affected by the changes ^[1].

NV Energy sold its California assets to Liberty Utilities in 2009 and has maintained temporary agreements to continue supply until Liberty finds alternative sources ^[2]. The shift will require Liberty to secure new power contracts to serve its customers around Lake Tahoe.

Meanwhile, Amazon signed contracts to help fund NV Energy’s plan to add 700 megawatts of low-carbon energy capacity, including 100 megawatts of geothermal power, to serve Reno data centers ^[2].

The power supply cut-off from NV Energy to Liberty Utilities is scheduled for May 2027, marking a key deadline for utilities and customers in the Lake Tahoe region to adapt to the changing energy landscape ^{[1, 2]}.
