Slightly Anti-Data Center Policies
Delaware requires large data centers seeking regulated utility service to obtain approval, cover grid costs, and meet energy and operating conditions; some projects face delays while a special tariff is developed. These rules can raise costs and risks but do not ban construction.
Incentives
Water and electricity
The measure provides for amounts collected under a possible Consumer Protection and Infrastructure Fee to be applied, after specified costs are recovered, as direct electricity bill credits for residential and small commercial customers to offset impacts from large energy use facilities (“direct bill credit to residential and small commercial customers”).
current law · StatewideRequires data centers using at least 30 megawatts to secure enough approved clean-energy generation for their annual power use, immediately or through a plan to reach that level within 10 years.Delaware HB 445 (2026)
What this means
The measure would make large data centers meet strict energy conditions: they must arrange for all their annual energy needs from qualifying nearby sources, and some may take up to 10 years to meet that target. The generation, grid-connection, contract, and penalty requirements could substantially raise costs and make projects harder, though they do not ban them outright.

The 30-megawatt threshold for code 518210.
Utilities or their regulatory bodies may aggregate multiple facilities and treat them as one large energy use facility if their location, electricity use, and operating characteristics pose reliability risks. Bulk crude-oil and petroleum-product facilities are generally excluded, but the exemption does not cover a qualifying new facility that adds unrelated uses. Multiple facilities may be aggregated.
A covered facility generally must produce or procure generation sufficient to meet 100% of its annual energy needs from facilities interconnected in Delaware, PJM’s DPL transmission zone, or a land-contiguous transmission zone with sufficient existing transmission capacity to deliver the electricity to Delaware. 100% of the facility’s annual energy needs.
Procured generation must have sufficient existing transmission infrastructure to reach Delaware and must not already have been committed in a prior PJM capacity auction. Previously auctioned capacity qualifies only to the extent attributable to an uprate or repowering. Not already been committed in a prior PJM capacity auction.
Generated power must meet the applicable renewable portfolio standard percentage and be produced by clean-energy technology. Eligible sources include qualifying renewable or clean-energy generation interconnected in Delaware, nuclear power, and Delaware-interconnected storage used primarily to store energy from the specified resources. Single-cycle and open-cycle generation are not acceptable. All power generated must meet the renewable energy portfolio standards.
A facility that does not initially meet the full-generation requirement must submit a plan for regulatory approval to reach 100% of its annual energy needs within 10 years of beginning operations; the plan must meet the generation and clean-energy rules. Within 10 years of commencing operations.
Facilities using the 10-year ramp-up option are subject to curtailment at price-impact thresholds set by the regulatory body and during specified reliability events, and must participate in PJM demand-response programs. If they keep operating during curtailment, their backup systems must meet at least 50% of power needs through battery storage or clean-energy technology. Must participate in PJM demand response programs.
The facility must seek out and fund new generation, either fully or in part. New energy production generation must be sought out and funded.
A facility may not connect to the electric distribution and transmission system until at least 25% of its required generation and 25% of its backup power from clean-energy technology are energized and interconnected. At least 25% of its required energy generation.
Before connecting, the facility must enter a 15-year binding contract with the utility’s regulatory body. The contract must include an insurance bond payable to the General Fund for specified failures, including failing to meet clean-energy obligations, attempting to terminate the contract, bankruptcy or similar proceedings, or violating the section. A 15-year binding contract.
A facility that falls short of its required renewable-energy production or procurement must pay a penalty set by the regulatory body, at least sufficient to cover the cost of the missing energy or the infrastructure needed to produce or procure it. Must pay a penalty.
The utility’s regulatory body may recover from the facility costs it incurs to make determinations or administer these requirements. Costs incurred by the electric utility’s regulatory body.
An electric distribution company may impose additional requirements on a large energy use facility. Imposing additional requirements.

A facility that cannot initially supply all its annual energy needs may operate under a plan approved by the utility’s regulatory body to reach 100% within 10 years. During that period it is subject to curtailment and demand-response requirements; if it continues operating during a curtailment, at least 50% of its backup power must come from battery storage or clean-energy technology. The 10-year ramp-up option
A facility may connect to the electric system before all required generation is in place once at least 25% of its required generation and 25% of its backup power from clean-energy technology are energized and interconnected. It must also enter a 15-year binding contract containing a guaranteed insurance bond. The 25% interconnection threshold
Facilities may meet their energy obligations through a combination of onsite or directly interconnected generation, power-purchase agreements, procurement, or another mechanism approved by the utility’s regulatory body. Eligible sources include qualifying renewable or clean-energy generation and nuclear power; energy storage interconnected in Delaware may also qualify when primarily used to store energy from specified eligible sources. Approved procurement methods
Generation procurement may draw on facilities in Delaware, the PJM DPL transmission zone, or a land-contiguous transmission zone with sufficient existing infrastructure to deliver the electricity to Delaware. Eligible supply may include new generation at an existing facility, uprates, and repowering of certain deactivated or retired units, subject to limits on capacity already committed in a prior PJM capacity auction.

current law · StatewideRequires large data centers to obtain state-approved power agreements, pay the costs they cause, and accept electricity cutbacks during grid emergencies.Delaware HB 233 (2026)
What this means
This is not a ban, but large data centers seeking service from regulated utilities must get approval, sign long-term agreements, provide financial guarantees, and pay costs tied to their grid connections; expanding an existing facility past the thresholds can also trigger the rules (ESA approval and cost protections). Emergency curtailment rules add operating risk, although qualifying new generation can avoid some curtailment requirements and existing facilities are generally exempt unless they expand (curtailment rules and exemptions; existing-facility provision).

The rules cover facilities meeting any of these thresholds: at least 75 MW monthly maximum demand at an 85% load factor; at least 100 MW instantaneous demand; or at least 30 MW monthly maximum demand for a facility primarily providing data-processing services. Facilities may be aggregated when the utility or regulator finds their combined electricity use, location, or operations create reliability risks. The large-facility thresholds and aggregation rule
A covered facility served by a regulated utility may not begin operating without Public Service Commission approval of an Electric Service Agreement (ESA) and a Transmission Security Agreement (TSA). The ESA must be approved before interconnection, and the facility cannot receive utility service until the applicable large-load tariff is approved. Prior ESA approval and a TSA are required
An ESA must impose a minimum contract term of 10 years after the load-ramp period and 15 years total including ramp-up. It must also require payment of at least 90% of contract capacity for distribution charges, and for utility-provided supply costs. Separately, the TSA must limit the load-ramp period to 10 years and set a demand floor of 90% of contract capacity. Minimum ESA terms and TSA ramp and demand-floor requirements
An ESA must require at least five years’ advance notice of termination and exit fees sufficient to cover unrecovered costs. Exit procedures and fees
Facilities must provide financial security, such as qualifying bonds, letters of credit, or cash-equivalent guarantees, to protect other customers against costs and obligations if the facility defaults, becomes insolvent, or terminates service. Financial guarantees in the ESA and TSA security
Facilities interconnected after December 31, 2026, are subject to utility load-shed protocols. In pre-emergency or emergency reliability events, large facilities must be curtailed before other comparable noncritical or critical loads, as applicable. They must support targeted or whole-facility curtailment with appropriate equipment, load separation, readiness measures, and telemetry. The statute provides an exception to specified curtailment requirements for facilities that construct or cause qualifying new generation meeting its location, capacity, and clean-energy criteria. Load-shed rules and their date limitation and new-generation exception
The ESA and tariff must assign costs attributable to the facility—including distribution upgrades, capacity procurement, transmission upgrades, studies, and certain PJM reliability-backstop obligations—to the facility or, where direct assignment is not possible, to the large-facility customer class. An independent incremental-cost test must compare facility revenues with incremental system costs; if revenues fall short, the utility and facility must propose added revenues, which may include a customer-specific fee. Cost assignment and the incremental-cost test
Facilities must contribute $0.000190 per kWh to the Low-Income Charge and $0.000712 per kWh to the Green Energy Fund. They are also treated as end-use customers for renewable portfolio standard purposes and must pay a proportional share of the specified qualified-fuel-cell-provider charge. Required per-kWh contributions and other charges
An ESA application must include specified information and studies, including transmission and distribution upgrades, electricity by generation type, curtailment plans, backup power, facility lifespan, and studies of Delaware electricity costs and grid reliability. The Commission reviews the agreement against regulatory requirements and considers cost allocation, reliability, economic and ratepayer impacts, environmental targets, public welfare, and the developer’s viability. Required application materials and Commission approval factors
A facility already operating on August 26, 2026, is excluded from the large-facility definition unless a change increases its use above the thresholds, in which case ESA approval is triggered. Bulk petroleum storage, processing, refining, or transfer facilities are excluded, subject to an exception if a new facility later adds unrelated uses and meets the thresholds. Existing-facility rule and bulk-petroleum exclusion
Benefits & exceptionsHide benefits & exceptions6
The Public Service Commission must decide a completed application for an Electric Service Agreement (ESA) within 90 days, with one possible extension of up to 90 days for good cause and in the public interest, providing a defined review timeline. ESA review deadline
A large energy use facility may buy electricity from a certified electric supplier; interconnection, distribution, or transmission service cannot be conditioned on buying supply from the regulated utility. Right to use a certified supplier
Building or arranging qualifying new generation is a positive factor in ESA review. The generation must meet specified location, capacity, and other criteria; certain criteria require consistency with state emissions targets or renewable portfolio standards. New generation as a positive factor
A facility that builds or causes construction of qualifying new generation can be exempt from specified curtailment requirements. The generation must be in Delaware or an eligible nearby transmission zone, not previously participate in PJM’s Base Residual Auction, match the facility’s demand, and meet state climate and renewable standards. Curtailment exemption
A facility already operating on August 26, 2026, is not treated as a large energy use facility under the new framework. An existing facility that later increases usage above the specified thresholds must obtain ESA approval. Treatment of existing facilities
The special large-facility framework applies only when a facility meets at least one statutory demand threshold: 75 MW monthly maximum demand at an 85% load factor, 100 MW monthly maximum instantaneous demand, or 30 MW monthly maximum demand for a facility primarily providing data-processing, hosting, or related services. Facilities below these thresholds do not meet this definition. Definition and thresholds

current law · StatewideDoes not specifically regulate data centers; it changes oversight, rate transparency, and cost-recovery rules for public utilities.Delaware SB 326 (2026)
What this means
The bill does not set data-center-specific rules; it mainly changes how public utilities are regulated. Its limit on certain utility spending excludes spending for new business and new customer requirements, so the sources do not show a meaningful barrier or benefit for data center projects.

Requires utilities to provide each customer class with a Rate Summary Table showing the total effective rate, every rate component, and the schedule for predictable rate changes. Utilities must include it in tariffs, websites, and customer bills and update it at least 30 days before rate changes, helping data centers plan and monitor electricity costs.
Limits recovery of annual non-mandatory capital spending by Commission-regulated electric distribution companies to 5% of the approved rate base, but excludes spending related to new business and new customer requirements. This preserves rate recovery for infrastructure needed to connect new data centers or expand service to them.
Beginning September 1, 2027, requires Commission-regulated electric utilities to bill standard offer service customers for transmission charges using the same monthly billing determinants as distribution rates, providing more consistent billing for data centers receiving standard offer service.

current law · StatewideGenerally excludes covered data centers from business tax incentives but preserves qualified-facility status for qualifying generation meeting annual energy needs.Delaware H 310 (2026)
What this means
The measure would remove job-creation tax credits and license-fee reductions for qualifying large energy-use facilities, including some data centers, making new projects or expansions a little less financially attractive (excludes large energy-use facilities from tax-credit eligibility). It does not add operating requirements or prohibit construction, so the practical impact appears minor.

Restrictions & requirementsHide restrictions & requirements2
Large energy-use facilities are excluded from eligibility for employment-creation and qualified-investment business tax credits and license-fee reductions. The definition generally covers facilities using at least 75 megawatts at an 85% load factor, 100 megawatts of instantaneous demand, or at least 30 megawatts while primarily providing data-processing, hosting, or related services under NAICS 518210. Multiple facilities may also be aggregated when an electric utility or regulator determines that their combined electricity use poses reliability risks. The bill excludes large energy-use facilities from qualified-facility status.
A large energy-use facility can retain qualified-facility status only if it produces or procures enough generation to meet 100% of its annual energy needs, obtains that generation from specified interconnected areas with sufficient transmission capacity, satisfies applicable renewable or clean-energy requirements, and does not rely on single-cycle or open-cycle generation. Compliance may use onsite or directly interconnected generation, power-purchase agreements, or other approved mechanisms.

A large energy use facility may qualify as a qualified facility—and therefore potentially remain eligible for the applicable business tax credits or license-fee reductions—if it produces or procures enough generation to meet 100% of its annual energy needs. The generation must meet specified geographic, transmission, renewable or clean-energy requirements; procurement cannot rely on capacity already committed in a prior PJM capacity auction, and single-cycle or open-cycle generation is excluded.

current law · StatewideProhibits state agencies, counties, and municipalities from agreeing to keep information about proposed or existing data centers using at least 100 megawatts of power from the public.Delaware Senate Bill 312 (2026)
What this means
If enacted, the measure would stop state and local governments from agreeing to keep information about data centers of 100 megawatts or more secret from the public (county rule, municipal rule). It does not ban data centers or set rules for building or operating them, so its direct practical effect on development is limited.

What this means
The measure delays new data centers needing at least 25 MW in Delmarva Power’s territory until a special electricity tariff is set, and that tariff could add costs. It does not ban projects, but its cost and timing are uncertain because the tariff is still being developed (tariff terms to be developed).
