Delaware Just Put Data Centers on Their Own Electric Rate. Your State Probably Hasn't.

If a data center gets built near you, somebody pays for the wires that feed it. Until recently, in most states, that somebody was you.

Delaware just changed the answer. On August 26, Governor Matt Meyer signed a four-bill package that puts large energy users in their own utility rate class and makes them cover the full cost of the infrastructure upgrades they trigger, instead of shifting those costs onto residential and small business customers. A second bill goes further: within ten years of starting operations, a large facility has to produce or procure 100% of the power it uses, including a renewable share. Delaware is the first state to write that “bring your own generation” requirement into law.

Two more pieces round it out. Large energy users lose access to job-creation tax credits and license fee reductions. And a separate bill limits what a for-profit utility like Delmarva Power can spend on discretionary capital projects and then recover from ordinary ratepayers.

Here is why a small state matters. Spotlight Delaware reported that the data centers proposed there have combined demand that could double Delaware’s entire electricity use, and that an independent analysis found wholesale power prices could rise as much as 80% under that scenario. That is the arithmetic every state is now doing.

What it costs you when nobody does this

The bill is not hypothetical. Clean Energy Group notes that Duke Energy has proposed an 18% rate increase in North Carolina that would add roughly $280 to $355 a year to the average household bill.

Your utility will not send a letter explaining which part of that is grid buildout for a data center. It arrives as “delivery” and “transmission,” the fastest-growing lines on a residential bill, and it stays for the twenty- or thirty-year life of the asset.

Nobody is arguing you should be able to veto a data center. The question is narrower and entirely about money: when the utility spends a billion dollars to serve one customer, does that customer pay for it, or does the rate class with the least bargaining power pay for it? Sticking the bill on households is the dumb answer, and eight states plus Delaware have now said so in writing.

Do this now

Check whether your state is on the list. Texas, Minnesota, Oregon, South Dakota, Florida, Tennessee, Oklahoma, New Jersey, and now Delaware have enacted some form of large-load cost protection. The thresholds are all over the place, from 10 megawatts in South Dakota to 150 in Alabama’s bill, so “we have a law” does not always mean “we have a law that catches the project down the road.”

If your state is not on the list, go to your public utilities commission website and look for your utility’s pending rate case or any large-load tariff filing. Comment periods are open to customers and they close fast. It takes one form.

And keep shopping the part of the bill you already control. If you are in a deregulated state, your supplier rate is still yours to switch, and if you own a home in a sunny state, our solar payback math is the other way out of a rising delivery charge. Neither one fixes who pays for the transmission line. That gets decided at the commission, this year, whether or not you show up.
