Nearly 50,000 people around Lake Tahoe face a looming power crisis as data centers built by tech giants including Alphabet, Amazon and Meta consume a growing share of Nevada's electricity. The area's utility, Liberty Utilities, gets roughly 75 percent of its power from Nevada-based NV Energy, which plans to end its decades-long supply agreement with Liberty in May 2027.
The region, often called a "billionaire playground," is home to sprawling lakeside estates that have sold for more than $100 million. California's side of Lake Tahoe counts Meta founder Mark Zuckerberg, Google co-founder Sergey Brin and Oracle co-founder Larry Ellison among its residents. The area also draws more than 25 million tourists a year to its ski resorts and lakeside casinos.
Liberty told California regulators on March 6 that NV Energy had changed its position on the arrangement, pointing to growing data center demand around the Tahoe-Reno Industrial Center and constraints on northern Nevada's transmission system as reasons for ending full service. Nevada already hosts at least 70 data centers, and a 2026 study estimated they could consume 35 percent of the state's electricity by 2030.
Danielle Hughes, a Lake Tahoe resident and California Energy Commission supervisor, told Fortune that it feels like Liberty's customers don't exist, describing them as 49,000 customers with no leverage. NV Energy disputed the idea that the decision came without warning, telling Fortune the transition had been under discussion for years. A company spokesperson also told FOX5 that NV Energy is not cutting power and will keep serving Liberty as it does now until Liberty secures its own transmission access, in order to ensure reliability throughout the process.
Why Northern Nevada Draws Data Centers
Northern Nevada has become a prime location for data centers because of its abundant undeveloped land, proximity to California's tech hubs and favorable tax incentives. Liberty is a California-owned utility whose rates are approved by state regulators, but its power network is deeply tied to Nevada. According to a regulatory filing, Liberty's grid falls within NV Energy's balancing authority, connects to the company at 38 points, and depends entirely on Nevada's transmission lines.
Fortune reported that unlike nearly every other California utility territory, Liberty's narrow service area along the state's eastern border sits outside the grid coordinated by the California Independent System Operator. That dependence has left Liberty scrambling to line up a replacement power supply before NV Energy's service ends. In March 2026, Liberty asked the California Public Utilities Commission for permission to fast-track bids for new electricity starting June 1, 2027.
Calls for a Fuller Review
Hughes and the Sierra Club's Tahoe Area Group are urging regulators to reject the expedited process in favor of a full public proceeding. In an April 1 letter to CPUC commissioners, Sierra Club Vice Chair Tobi Tyler argued that a decision affecting 49,000 customers on an isolated and rapidly changing grid requires greater transparency and public participation. A protest filed by Tahoe Spark warned that California does not produce a Liberty-specific forecast assessing electricity demand, peak conditions or the power needed by communities in an area at high risk of wildfires.
Data centers consumed 22 percent of Nevada's electricity in 2024, a share that could climb to 35 percent by 2030. Sierra Club testimony filed with Nevada regulators found that data centers account for roughly 75 percent of the expected increase in demand from major projects under NV Energy's 2024 resource plan. Most of that growth is concentrated in northern Nevada, adding further strain to the same power system that supplies Lake Tahoe.
