HB 233 Delaware House · 153rd General Assembly (2025-2026)

AN ACT TO AMEND TITLE 26 OF THE DELAWARE CODE RELATING TO LARGE ENERGY USE FACILITIES.

Summary
This Act requires regulated utilities to establish a separate rate class for large energy use facilities that mitigates the risk of costs associated with expanding infrastructure and maintaining reliability in the face of growing demand from being shifted to residential, small business, and other electric customers. Wherever possible, the costs of large energy use facilities should be directly assigned to those facilities, and where direct assignment is not possible, the costs should be allocated to the class of large energy use facilities and not to other customer classes. To accomplish this, the Act sets forth minimum requirements for Electric Service Agreements (ESAs) and Transmission Security Agreement (TSAs) to be in place for any large energy use facility. The Commission shall promulgate regulations to implement these agreements. ESAs shall be reviewed and approved by the Commission prior to the interconnection of a large energy use facility and provide a regulatory framework to enable responsible developers of large energy use facilities to enter into agreements to fairly allocate costs among customer classes. The Public Service Commission will consider several factors in determining whether to approve an ESA, including consistency with the Commission’s regulations; whether the ESA and tariff ensure that all costs attributable to the large energy use facility are assigned to the class of large energy use facilities; whether other customers are adequately protected from the risk of paying stranded asset costs; the impact of the large energy use facility on delivering safe, adequate, and reliability electricity; the impact on the State, including the economy, other ratepayers, and environmental impacts; and the viability of the developer of the facility. In combination, the ESAs and the large load tariff shall ensure that, wherever possible, distribution infrastructure investment costs, capacity procurement costs, reliability backstop procurement costs, transmission infrastructure costs, and study costs attributable to a large energy use facility are all directly assigned to that large energy use facility. Where direct assignment is not possible, these costs should be allocated to the class of large energy use customers. The Commission shall develop an “incremental cost test” to measure the revenues and costs from a large energy use facility to ensure that there are not cost shifts to other customers. The Act further establishes interruptability requirements for large energy use facilities to ensure other customers are protected from reliability impacts caused by large energy use facilities. Facilities that construct or cause to be constructed new in state generation may exempt themselves from interruptability. Finally, the Act requires large energy use facilities to contribute to the low income fund and green energy fund at higher rates than other customers and requires large energy use facilities to contribute to renewable portfolio standard costs and qualified fuel cell provider costs. The Act takes effect upon enactment and regulated utilities must file an application to establish rates required under this Act within 180 days of the effective date.

SA 2 to HS 1 for HB 233 Bill Text · 10 edits
MAJOR
This is the transition from Senate Amendment No. 2 to the final enacted Bill Text of HB 233, which establishes a comprehensive regulatory framework for large energy use facilities (primarily hyperscale data centers) in Delaware. The final text significantly lowers the threshold for what qualifies as a large energy use facility (from 75 MW to 50 MW at 85% load factor), removes the petroleum refinery exemption and the NAICS-code-based prong, adds detailed minimum requirements for Electric Service Agreements and Transmission Security Agreements, creates an Incremental Cost Test mechanism, establishes curtailment protocols, and imposes specific per-kWh fees on large energy use facilities. The bill also changes sponsorship to a multi-chamber coalition and takes effect immediately upon enactment.
DEFINITION

The threshold for 'large energy use facility' was lowered from 75 MW to 50 MW at an 85% load factor. The third prong (30 MW plus NAICS code 518210 for data center services) was removed entirely, and the petroleum/refinery exemption was also removed. New definitions for 'load ramp period' and 'contract capacity' were added.

REQUIREMENT

Section 203G now requires ESAs to include 12 minimum provisions: 10-year minimum contract term (15 years total including load ramp), 90% demand floor for distribution and supply charges, 5-year maximum load ramp period, 5-year advance termination notice, exit fees for unrecovered costs, curtailment readiness measures, enforceable interruptibility obligations, bonding or letters of credit backed by investment-grade entities, and local labor/prevalent wage considerations.

A detailed load shed protocol was added requiring utilities to curtail large energy use facilities before other loads during emergencies, with a hierarchy: pre-emergency curtailment under PJM Connect and Manage framework first, then non-critical large energy use facilities, then critical large energy use facilities. Facilities that build new in-state generation meeting specific criteria (not previously in PJM Base Residual Auction, matching load characteristics, consistent with state emissions and RPS targets) are exempt from curtailment requirements.

ENFORCEMENT

A new Incremental Cost Test (ICT) mechanism was added requiring an independent consultant retained by the Commission to measure revenues from a large energy use facility against incremental costs on a 3-year cycle. If revenues are lower than incremental costs, the utility must develop a proposal to bring additional revenues, potentially including a class-specific Consumer Protection and Infrastructure Fee. Surplus funds after cost recovery must be applied as direct bill credits to residential and small commercial customers.

The Commission's approval factors for ESAs were expanded to 9 items, adding consideration of Community Benefits Agreements, developer viability and experience, impact on the local area, and whether the project triggers supplemental transmission projects. Application requirements now include 8 specific items including studies of impact on electricity costs and grid reliability in Delaware.

A new annual reporting requirement was added: utilities must provide the Commission with detailed project-specific information for each anticipated large energy use facility, and the Commission must submit a report to the Governor and General Assembly by December 31 of each year listing ESA applications received and their disposition.

FISCAL

Large energy use facilities must contribute to the Low-Income Charge at $0.000190 per kWh and to the Green Energy Fund at $0.000712 per kWh. They are classified as 'end-use customers' for renewable portfolio standard purposes (losing any exemption) and must bear a proportional allocation of fuel cell provider charges.

TIMELINE

The Commission must act on ESA applications within 90 days (extendable by 90 days for good cause). Utilities must establish the new rate class within 180 days of finalization of Commission regulations. The load shed protocol applies only to loads interconnected after December 31, 2026. The Act takes effect upon enactment.

SCOPE

A grandfathering provision was added: facilities already in operation as of the effective date are not considered large energy use facilities, but any expansion that increases usage above the thresholds triggers the ESA approval requirement. ESAs also cannot be transferred to another entity without written Commission approval.

The bill changed from a single-sponsor Senate amendment (Sen. Hansen) to a multi-chamber bill sponsored by Rep. Burns, Rep. Heffernan, Rep. Minor-Brown, and Sen. Hansen with additional co-sponsors from both chambers, indicating broader legislative support for the final version.
