California Data Center Deal Puts New Large Loads on a Cost-Causation Track

Core Elements of the California Package

Implications for Developers and Hyperscalers

• Power diligence will need to start earlier. Developers will need a clearer picture of a project’s expected load and the cost of serving it before making significant development and financing commitments. The proposed tariffs would tie those assumptions to minimum-payment, load-ramp and credit requirements, with financial consequences if expected load does not materialize. Interconnection applicants also would have to disclose applications for the same data center in other utility territories or jurisdictions.
• The consequences of delay or underperformance will need to be addressed contractually. SB 886 and AB 2383 contemplate financial consequences if a project fails to ramp as expected or exits early, including early-termination charges and protections against stranded interconnection and generation costs. Those risks should be considered in utility arrangements and other project documents that depend on the timing and cost of energization.
• Behind-the-meter generation is not a complete safe harbor. AB 2383 expressly allows qualifying zero-emission-behind-the-meter resources to reduce a data center’s obligation to pay incremental generation costs, but only to the extent attributable to those resources. The legislation does not otherwise displace applicable permitting and environmental requirements.

Implications for California Electric Utilities

• Utilities will need to develop new tariff structures. Investor-owned utilities can anticipate CPUC filings addressing threshold design, service categories, cost causation, upgrade assignment, generation procurement, ramp requirements, deposits, exit fees, and protections for bundled and unbundled customers.
• Build a defensible interim pathway. The compromise legislation permits interim utility agreements before final statewide rules. Utilities will need to document cost allocation, nondiscrimination, credit protection, consistency with existing tariffs and transition mechanics into the permanent regime.
• Coordinate planning assumptions. Because the legislation ties cost recovery to expected load and protects against inadequate ramp-up and early departure, utilities will need greater confidence in projected data-center demand when planning interconnection and generation procurement.

How California Compares with Other Major State Initiatives in Texas and New York

Texas. Texas enacted SB 6 in 2025 and, on August 3, 2026, Gov. Greg Abbott directed Public Utility Commission of Texas (PUCT) and Electric Reliability Council of Texas (ERCOT) to verify and audit data centers advancing through ERCOT’s interconnection process. The review calls for information concerning incentives, electricity supply and demand, water and cooling, community mitigation, and ownership. PUCT later allowed ERCOT to proceed under modified Batch Zero procedures while conducting verification.

New York. Gov. Kathy Hochul issued Executive Order 62 on July 14, 2026, temporarily pausing specified state environmental permits for new hyperscale data centers while the state develops a generic environmental impact statement and a broader regulatory framework. New York also is pursuing utility rate and cost-allocation reforms and reconsidering incentives. The Legislature separately passed the Responsible Data Center Development Act, but that bill has not yet been signed by Gov. Hochul.

The broader trend. California, Texas and New York use different legal tools, but point toward the same national baseline: Large data-center loads increasingly must demonstrate project maturity, bear identifiable system costs, provide stronger long-term commitments, and address power, water, environmental and community impacts. California’s negotiated model is less restrictive than New York’s moratorium and more tariff-centered than Texas’s audit, but all three approaches reduce the value of a queue position unsupported by commercial readiness.

Pillsbury Perspective
California is choosing managed growth rather than a statewide moratorium. The policy bargain is a clearer development pathway in exchange for tighter cost causation and stronger commitments. For credible, well-capitalized projects, dedicated tariffs may ultimately improve visibility into service requirements and reduce the risk that speculative requests consume scarce planning capacity. But the transition period will carry execution risk as project economics depend on evolving tariff, upgrade-cost, procurement and power supply requirements.

Developers, hyperscalers, utilities, lenders and power suppliers should work from a common project record that reconciles site control, megawatt ramp, interconnection studies, procurement assumptions, credit support, water and cooling design, local approvals, and contractual milestones. Transactions should include change-in-law and regulatory-delay mechanisms broad enough to capture both final legislation and subsequent CPUC implementation.

Immediate Action Checklist for Data Center Developers, Hyperscalers and Utilities

• Map each California project to the likely tariff threshold, service voltage, utility territory, community choice aggregation (CCA) or direct-access status, and anticipated energization date.
• Reconcile queue applications and prepare a disclosure record for duplicate or alternative applications.
• Quantify transmission, distribution, generation-procurement, cancellation, ramp and early-exit exposure under downside scenarios.
• Add regulatory milestones, cost caps or sharing rules, extension rights, and termination protections to land, power, customer, financing and construction documents.
• Engage early in CPUC implementation rulemaking proceedings to address thresholds, exemptions, interim agreements, confidentiality, locational maps, and treatment of onsite generation, storage and flexible load.
