PG&E's Initiative to Expand Data Center Energy Supply in Northern and Central California

Accelerating Energy Supply for Data Centers in California

Pacific Gas and Electric Company (PG&E) is embarking on a significant initiative to address the increasing energy demand from data centers across Northern and Central California. Over the next decade, PG&E is preparing to support approximately 5.5 gigawatts (GW) of new energy requirements from these facilities, with the first phase of 1.4 GW already in the final design phase and set to operational between 2026 and 2030. This expansion signifies not only a response to technology's growing footprint but also an innovative approach to energy distribution that could benefit millions of customers.

Understanding the Impact of 5.5 GW Energy Demand

To put the projected 5.5 GW of energy demand into perspective, this amount of electricity is sufficient to power approximately 750,000 homes simultaneously. The demand stems from 15 customers across 27 unique sites, located primarily within Silicon Valley and the broader San Francisco Bay Area. PG&E's projections highlight that for every gigawatt of new load served, residential customers could see a decrease of 1-2% in their monthly bills over time. The underlying principle is that expanding the energy load helps to optimize the existing electric infrastructure, allowing costs to be spread out among a larger base of energy units, effectively lowering individual customer expenses.

The Rule 30 Tariff Proposal

To accommodate this growth, PG&E has proposed a new 'Rule 30' tariff to the California Public Utilities Commission. This plan is designed to provide a clear and streamlined process for connecting large power consumers, such as data centers and tech campuses, to the existing grid. The proposed tariff outlines the interconnection process and associated costs in a manner that ensures transparency and equity.

This new regulation aims to meet the rising demands efficiently, while also allowing large load customers the option to fund their projects upfront, streamlining the timeline for service connection. By enabling these customers to cover their initial costs, PG&E anticipates a quicker transition to new energy sources, enhancing service responsiveness and stability for its consumer base.

The Future of Energy with Data Centers

In an evolving energy landscape, Jason Glickman, PG&E's executive vice president, expressed optimism about this strategy, noting that embracing beneficial load growth—in this case, the energy demands of data centers—will not only optimize current resources but also pave the way for future electricity developments. This thoughtful approach signifies a partnership with leading innovators in technology, affirming California's status as a hub for technological advancement.

In addition to powering data centers, PG&E is witnessing an influx of applications for other large energy loads such as warehouses and electric vehicle facilities, marking a shift towards an energy-efficient future for the state. As PG&E embraces innovative technologies and rushes to meet these demands, the company is also ensuring that current customers remain safeguarded from financial burdens associated with infrastructure that may not deliver the anticipated energy load.

As part of this initiative, PG&E will also host the upcoming DTECH Data Centers and AI conference in San Jose from May 27-29, 2025. The event will focus on the utilities' role in adapting to AI-driven data center demands, highlighting PG&E's commitment to sustainability and innovation in serving California's energy needs.

By facilitating new energy projects and focusing on collective benefits for its consumers, PG&E stands at the forefront of an energy revolution, poised to make significant strides in navigating the future of power supply, infrastructure utilization, and technological growth.
