California is experiencing a unique opposition to data centers, driven not only by public concern but also by significant economic and regulatory barriers. While communities across the state are enacting bans and restrictions, high electricity prices, grid connection delays, and generator size limitations are inherently curbing the expansion of these facilities.
Unlike other states grappling with proposals for massive data center complexes, California's industrial electricity rates, which are more than double the national average, present a substantial deterrent. Coupled with lengthy waits to connect new facilities to the power grid, these factors have led to some data centers remaining unoccupied in Silicon Valley. Furthermore, state regulations cap the size of backup generators, restricting facilities to a capacity insufficient for the growing demands of artificial intelligence.
"California isn’t even on the map today," stated Mehdi Paryavi, chairman of the International Data Center Authority, citing high taxes, expensive land, water scarcity, and energy challenges as additional obstacles. Consequently, many data center demands originating from California are being met by adjacent states like Arizona and Nevada, which offer more affordable power, land, and less stringent regulations, according to Andrew Batson, head of data center research at JLL.
Despite these challenges, California anticipates future growth. Fifty-one new data centers are planned, representing an 18% increase from the current 277 operational facilities. Data center electricity consumption in the state doubled between 2019 and 2023. However, this projected growth is modest compared to other regions and is expected to represent a smaller share of national data center power demand. While concerns remain about increased electricity demand, particularly from electric vehicles, projections indicate that data centers will contribute a significant but manageable portion of California's future energy needs.
Regulatory measures, such as a rule requiring backup generators over 100 megawatts to be certified as power plants, further limit the scale of data centers in California. This regulation means most current and proposed facilities fall below the threshold, unlike the larger facilities planned elsewhere. This, combined with the state's high energy costs and land prices, has led to a situation where California facilities currently account for approximately 5% of national data center power demand, a figure projected to decrease significantly if national building plans proceed as anticipated.
The growth that does occur is raising concerns among utility ratepayer advocates and environmentalists. Mark Toney, executive director at The Utility Reform Network, highlighted that Pacific Gas & Electric anticipates a substantial increase in demand from data centers, potentially requiring significant grid upgrades borne by ratepayers. Efforts are underway to shield ratepayers from these costs, with proposed legislation aiming to ensure data centers cover the full costs of new transmission infrastructure and contribute to clean energy generation. The industry, however, is resisting these proposed regulations.
