Governor Matt Meyer signed four energy bills on 26 August, all effective immediately. The package is being described as the first state law in the country requiring data centres to bring their own clean power. The description is close to right, and the two qualifications that go with it are the whole story.
What the four bills do
HB 445 is the one making headlines: it requires large energy use facilities to produce or secure the power they consume, ramping under a plan filed with the Public Service Commission so that by the 10th year of operations the facility covers 100% of its usage. HB 233 creates a separate rate classification for large energy facilities so they "pay the full cost of infrastructure upgrades rather than shifting those costs to residential and small-business customers." HB 310 denies those facilities access to job-creation tax credits and licence-fee reductions. SB 326 expands regulatory review of non-mandatory capital expenditure by for-profit utility monopolies.
What the common framing gets wrong
The bill as introduced required generation in state. Senate Amendment 1, introduced on 19 June, widened the acceptable location to PJM transmission zones contiguous by land with the Delmarva zone, where sufficient transmission resources exist. In practice that admits generation from neighbouring states — an expansion of the Salem nuclear facility in New Jersey being the example most often cited. So "data centres must build clean power in Delaware" became "data centres must contract for power in Delaware or an adjacent grid zone." That is still a meaningful obligation, and it is a materially weaker one than the headline conveys. The second gap is time: nothing binds at full strength until year ten of a facility's operations, and for a facility that has not broken ground, that is well into the 2030s.
Why the cost bill may matter more
HB 233 is the less-discussed measure with nearer-term teeth. Interconnection and transmission upgrades for a large load are expensive, and the default in most jurisdictions is that some of that cost is socialised across the ratepayer base. A separate rate class that assigns the full cost to the facility requesting it changes the arithmetic of siting immediately, on the next application — not in a decade.
What is not settled
The Public Service Commission still has to write the tariff and the ramp-up plan requirements, and the definition of "large energy use facility" determines who is covered at all. Neither the megawatt threshold nor the compliance mechanics are resolved by the signing. What was signed is a framework and a deadline a decade out; what will determine whether Delaware's grid absorbs data-centre load without pushing costs onto households is regulatory work that has not started.
