Rapid growth in energy demand — driven in part by data centers, electrification, and population growth — is reshaping regional electricity markets and infrastructure planning throughout the country. For communities in the Sierra, and particularly in the Tahoe Basin, those changes are becoming increasingly relevant.

Electricity to the Tahoe Basin is primarily supplied by Liberty Utilities, a California-serving investor-owned utility that receives about 75% of its power from NV Energy. NV Energy’s current contract to provide energy to Liberty Utilities and its customers extends until May of 2027.  Earlier this year, NV Energy announced that it would not be renewing that contract, leaving Liberty Utilities searching for new electricity supplies. Liberty Utilities subsequently filed a Tier 3 advice letter with the California Public Utilities Commission (CPUC), asking for an expedited timeline to secure new power contracts. The letter also highlighted NV Energy’s recent forecast that it will need 47% more electricity due to the rise of data centers in the Reno area. 

The Tahoe Reno Industrial Center, where Apple, Alphabet (the parent company of Google), Microsoft, and other major tech companies have opened or will open new data centers, is the third-largest data center market in the country. There are over 60 operating data centers in Nevada, with a massive, rapid expansion focused in NV Energy territory, particularly around Reno and Las Vegas. As of mid-2025, roughly 13 million square feet of data center space was under construction, with a dozen new projects requesting 6 gigawatts of power capacity.

So what does this all mean for Liberty Utility customers in the Tahoe Basin and the seven counties in rural California that it serves? The cancelled NV Energy contract will lead to Liberty Utilities having to compete in the open market for power purchase contracts against some of the largest players in the world, which raises valid concerns about affordability, supply reliability, transmission capacity, and availability of renewable energy as a percentage of our local Liberty energy portfolios. 

Average electricity costs in California are already among the highest in the nation, averaging about $0.33 per kilowatt hour (kWh). Liberty’s average cost has been consistent with this average, but could get pushed much higher if competition forces it.

The energy burden in the Lake Tahoe region is already exceptionally high, with residents facing costs roughly 47% higher than the national average, at approximately $0.34 per kWh as of April 2026. This burden is exacerbated by a winter-peaking grid driven by tourism and a high percentage of second homes. Utility rates for Liberty customers roughly doubled between 2020 and 2025, and the new rate case approved earlier this year calls for an additional 20% increase before the NV Energy announcement. 

Meanwhile, western wholesale electricity prices — which serve as a baseline for contracts — surged in early 2026 to more than double current NV Energy rates in some peak periods. There is no way to anticipate exactly what rate Liberty Utilities will be able to secure; however, upward pressure on rates is certain to continue as data centers and demand proliferate. 

Local businesses in the Tahoe region, especially in energy-intensive businesses like hospitality, grocery, recreation, and tourism, are already feeling the pressure of rising operating costs and the ever-increasing cost of living. 

The Tahoe region — with its unique intersection of rural communities, tourism economies, environmental stewardship, and proximity to growing, major tech infrastructure — stands to serve as a bellwether for challenges other Western communities will increasingly face as rapid data center expansion reshapes regional energy markets, utility systems, and, ultimately, household energy costs.

Rural and mountain communities must have a voice in these conversations.

Concerned advocates from local communities, Tahoe SPARK, and other Tahoe Basin residents are speaking out about how the rapid growth of data centers and the resulting competition for clean, reliable, and affordable energy might impact the Tahoe Basin and Liberty’s 50,000 customers. 

Alongside these community advocates, SBC intends to file a request to become party to the California Public Utilities Commission proceedings to advocate for transparency, ratepayer protection, long-term grid resilience, and expanded access to renewable energy resources in Liberty’s procurement process. 

This is an opportunity to have larger conversations about transmission infrastructure, regional energy coordination, and how the costs of rapid energy demand can be most equitably distributed among the industries, companies, and communities benefitting from these emerging and evolving technologies.

If we approach this challenge with transparency, collaboration, and long-term thinking, Tahoe has an opportunity to not only protect its own future but help model what resilient regional energy leadership can look like for communities across the West.
