Hyperscale Datacenter Boom Strains California's Resources
The rapid expansion of hyperscale datacenters in California, driven by AI and cloud computing, is creating significant workforce and infrastructure challenges. The industry faces a pronounced skills shortage as experienced workers retire, along with bottlenecks in securing reliable power and essential construction components. These pressures require new strategies for workforce development, supply chain management, and energy procurement.
- Data centers in California consumed approximately 5,580 gigawatt-hours (GWh) of electricity in 2023, which is about 2.6% of the state's total electricity demand for that year. Projections from the Lawrence Berkeley National Laboratory suggest this load could double or even triple by 2028. - In 2023, data centers in California used an estimated 50 billion liters of water, primarily for cooling servers, and that figure is projected to potentially increase to 116 billion liters by 2028. However, a significant lack of transparent reporting from data centers makes it difficult to understand the precise impact on local water resources. - In response to concerns about the strain on resources, State Senator Steve Padilla introduced two bills, SB 886 and SB 887, in early 2026. These bills aim to establish a tariff for data center customers and ensure they are not exempt from the California Environmental Quality Act, while also providing a potential fast-track for construction if certain environmental criteria are met. - Governor Gavin Newsom has previously vetoed legislation that would have mandated data centers to report their water and energy usage. His reasoning was a reluctance to impose rigid reporting requirements on the sector without a full understanding of the potential impacts on the industry. - The competition for skilled labor is intense, with a nationwide survey by the Associated General Contractors of America showing that over 80% of construction firms are struggling to fill both hourly and salaried positions. To attract talent in California, some companies are redefining job roles to focus on transferable skills in areas like power systems and cooling technologies. - Southern California experienced a significant increase in data center leasing activity, with 14.2 megawatts of net absorption in 2022, an 85.6% increase from the previous year. Over 95% of the data center space under construction at the end of 2022 had already been pre-leased. - Supply chain disruptions are causing significant delays, with wait times for grid connections sometimes stretching for years. This has led to completed data centers in Silicon Valley sitting empty as they await power from the local utility, which may not have the capacity to supply them until upgrades are completed. - While California has historically been a major hub, a 2026 report from JLL indicates a shift, with 64% of new data center development in North America occurring outside of primary markets like Silicon Valley. States like Ohio, Tennessee, and Wisconsin are now seeing more data center construction than California.
