캘리포니아의 새로운 데이터센터 계약은 대규모 부하 간 연계 비용 배분을 위한 비용 유발 프레임워크를 확립했다.

California lawmakers have announced a negotiated legislative package centered on Senate Bill 886 (SB 886) and Assembly Bill 2383 (AB 2383). This framework places qualifying data centers under dedicated interconnection, transmission and distribution, and generation-service regimes overseen by the California Public Utilities Commission (CPUC). Designed to prevent stranded costs and avoid shifting expenses to ratepayers, the package requires developers and hyperscalers to prepare for earlier due diligence, extended procurement timelines, firm load commitments, heightened cost responsibility, explicit ramp and exit protections, and stricter scrutiny of duplicate queue applications. Concurrently, California utilities must prepare updated tariff records, cost studies, service maps, interconnection agreements, and interim contracting protocols.

September 1, 2026. On August 28, 2026, California lawmakers announced a late-session compromise involving Governor Gavin Newsom regarding two bills that address the electricity demands of data centers. Following passage by both chambers on August 31, 2026—the final day of the legislative session—the bills now proceed to the Governor’s desk for signature. The package directly addresses ratepayer concerns over generation and grid-upgrade costs tied to data center expansion while deliberately avoiding a statewide development moratorium. The core legislation consists of SB 886, introduced by Senators Steve Padilla and Jerry McNerney, and AB 2383, introduced by Assemblymember Rick Chavez Zbur. The enacted framework mandates that the CPUC establish specialized rates and updated regulatory rules for data center electricity consumption, explicitly assigning qualifying facilities responsibility for grid upgrades necessitated by their interconnection requests.

**Core Elements of the California Package**

**Implications for Developers and Hyperscalers**

Power due diligence must begin earlier. Developers will require a precise understanding of a project’s anticipated load and the associated service costs before advancing major development and financing commitments. Under the proposed tariff structures, these projections will be bound by minimum payment, load ramp, and credit requirements, triggering financial penalties if projected demand fails to materialize. Additionally, interconnection applicants must disclose any concurrent applications for the same facility across other utility territories or jurisdictions.

Contractual provisions must explicitly address delay or underperformance. Both SB 886 and AB 2383 outline financial repercussions for projects that fail to meet ramp schedules or terminate operations prematurely, including early-termination fees and safeguards against stranded interconnection and generation expenses. These risks must be systematically integrated into utility agreements and ancillary project documentation governing energization timelines and costs.

Behind-the-meter generation does not provide a comprehensive exemption. While AB 2383 permits qualifying zero-emission behind-the-meter resources to offset a data center’s incremental generation cost obligations, relief applies strictly to the portion of costs directly attributable to those resources. The legislation does not waive existing permitting, environmental, or compliance requirements.

**Implications for California Electric Utilities**

Utilities must develop new tariff architectures. Investor-owned utilities should anticipate forthcoming CPUC filings that will define threshold designs, service classifications, cost-causation methodologies, upgrade assignments, generation procurement strategies, ramp specifications, deposit structures, exit fees, and consumer protections for both bundled and unbundled ratepayers.

Establishing a defensible interim pathway is critical. The compromise legislation authorizes provisional utility agreements ahead of finalized statewide regulations. Utilities must meticulously document cost-allocation methodologies, nondiscrimination principles, credit safeguards, alignment with existing tariffs, and transition mechanisms into the permanent regulatory framework.

Planning assumptions require tighter coordination. Since cost recovery is explicitly tied to projected load and statutory protections guard against insufficient ramp-up or premature departure, utilities must achieve higher certainty in data center demand forecasts when scheduling interconnection studies and generation procurement.

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

Texas. In 2025, Texas enacted SB 6. On August 3, 2026, Governor Greg Abbott directed the Public Utility Commission of Texas (PUCT) and the Electric Reliability Council of Texas (ERCOT) to verify and audit data centers progressing through ERCOT’s interconnection pipeline. The review requires detailed disclosures regarding incentives, electricity supply and demand dynamics, water and cooling infrastructure, community mitigation strategies, and corporate ownership. Subsequently, the PUCT authorized ERCOT to continue processing applications under modified Batch Zero procedures while verification efforts proceed.

New York. On July 14, 2026, Governor Kathy Hochul issued Executive Order 62, temporarily suspending certain state environmental permits for new hyperscale data centers while the state drafts a generic environmental impact statement and establishes a comprehensive regulatory framework. New York is simultaneously advancing utility rate and cost-allocation reforms and reassessing existing incentives. Although the state Legislature independently passed the Responsible Data Center Development Act, Governor Hochul has not yet signed it into law.

The broader trend. While California, Texas, and New York employ distinct regulatory instruments, they converge on a common national standard: large data center loads must now demonstrate project maturity, assume identifiable system costs, secure robust long-term commitments, and comprehensively address power, water, environmental, and community impacts. California’s negotiated approach is less restrictive than New York’s permit moratorium and more tariff-driven than Texas’s audit mechanism, yet all three frameworks diminish the strategic value of interconnection queue positions lacking commercial readiness.

**Pillsbury Perspective**

California has opted for managed growth over a statewide development moratorium. The resulting policy trade-off offers a more predictable development pathway in exchange for stricter cost-causation principles and binding operational commitments. For financially sound and well-capitalized projects, dedicated tariffs may ultimately enhance transparency regarding service requirements and mitigate the risk that speculative applications monopolize limited planning capacity. However, the transitional phase introduces notable execution risk, as project economics will hinge on continuously evolving tariff structures, upgrade expenditures, procurement timelines, and power supply conditions.

Developers, hyperscalers, utilities, lenders, and power suppliers must operate from a unified project record that aligns site control, megawatt ramp schedules, interconnection studies, procurement assumptions, credit enhancements, water and cooling engineering, municipal approvals, and contractual milestones. All transactional documents should incorporate change-in-law and regulatory-delay provisions sufficiently broad to encompass both enacted legislation and subsequent CPUC rulemaking.

**Immediate Action Checklist for Data Center Developers, Hyperscalers and Utilities**

• Map each California project to its anticipated tariff threshold, service voltage, utility territory, community choice aggregation (CCA) or direct-access classification, and projected energization date.

• Cross-reference interconnection queue submissions and compile a comprehensive disclosure record for any duplicate or alternative applications.

• Model transmission, distribution, generation procurement, cancellation, ramp, and early-exposure liabilities under downside scenarios.

• Integrate regulatory milestones, cost caps or cost-sharing mechanisms, extension rights, and termination safeguards into land acquisition, power purchase, customer, financing, and construction agreements.

• Participate proactively in CPUC implementation rulemaking proceedings to shape thresholds, exemptions, interim contracting frameworks, confidentiality protocols, locational mapping, and the regulatory treatment of onsite generation, storage, and flexible load.
