According to DCD, California utility Pacific Gas & Electric has seen its data center pipeline decline by 400MW to 9.6GW in its Q3 earnings report. CFO Carolyn Burke attributed the reduction to the company’s “no big bets plan,” while CEO Patricia Poppe noted the pipeline remains robust with 18 projects totaling 1.6GW now in final engineering stage, up from 1.5GW in Q2. The utility expects 95% of these advanced-stage projects to achieve operational status by 2030, with several coming online as early as 2026, and maintains its $73 billion capital investment plan unchanged from Q2 results. This strategic shift reflects a more selective approach to data center development while advancing projects with higher certainty of completion.

The California Power Reality Check
What PG&E’s pipeline adjustment reveals is the harsh reality of power constraints in America’s most populous state. Unlike states like Virginia or Texas with abundant land and power capacity, California faces unique challenges including wildfire risks, environmental regulations, and transmission bottlenecks. The utility’s decision to avoid expanding its capital plan due to low stock valuation indicates investor pressure for disciplined spending rather than chasing every potential data center customer. This represents a significant departure from the “build it and they will come” mentality that has characterized some utility approaches to data center growth.
The Strategic Bet on AI Inference
PG&E’s emphasis on AI inference workloads represents a sophisticated understanding of the AI compute landscape. While AI training requires massive, concentrated power loads often located near renewable energy sources, inference workloads—where trained models process real-world data—benefit from proximity to end-users and existing technology ecosystems. Silicon Valley’s concentration of AI companies, venture capital, and technical talent creates natural demand for inference capacity. This positioning allows PG&E to leverage its geographic advantage without competing directly with regions offering cheaper power for training workloads.
The Grid Innovation Imperative
The partnership with Smart Wires highlights a critical trend: utilities can no longer simply build more capacity—they must optimize existing infrastructure. Smart grid technologies that dynamically manage power flows represent the future of data center power delivery in constrained markets. PG&E’s Implementation Agreement with San Jose to guarantee power delivery for large loads suggests the utility is developing new commercial models to manage risk and provide certainty to data center developers facing uncertain interconnection timelines.
The Ratepayer Economic Balancing Act
PG&E’s claim that data center connections could reduce other customers’ bills by 1-2% represents a crucial public relations strategy. As data centers face increasing scrutiny for their energy consumption, utilities must demonstrate broader economic benefits. However, this calculation depends heavily on how infrastructure costs are allocated and whether data center demand drives new capacity investments that ultimately benefit all ratepayers. The reality is more complex than simple arithmetic, involving regulatory decisions about cost recovery and the timing of capacity additions.
Broader Market Implications
PG&E’s more selective approach signals a maturation of the data center market in premium locations. We’re likely to see similar patterns emerge in other supply-constrained regions like Singapore and Ireland, where utilities are becoming more discerning about which projects they can realistically support. This could accelerate development in secondary markets with better power availability while forcing data center operators to innovate in energy efficiency and power management technologies. The era of unlimited data center growth in any location is ending, replaced by a more strategic, infrastructure-aware approach to site selection.
