A new Powerlines study reported Wednesday by Ohio Capital Journal finds that the country's 51 investor-owned utilities plan to spend $1.4 trillion on capital projects through 2030 — and have already filed $31 billion in rate-increase requests in 2025 alone that have not yet fully reached customer bills. The two largest Ohio-facing plans are Duke Energy's $103 billion national program ($3.25 billion of it in Ohio) and AEP's $72 billion across 11 states ($5.7 billion of it in Ohio).
On the same day the study surfaced, two Ohio rate decisions made the abstract capex picture concrete on April bills.
AEP Ohio. The Public Utilities Commission of Ohio approved AEP Ohio's distribution rate case — an $11 million revenue increase, scaled down sharply from the $97 million the company originally sought. The settlement also introduces a new minimum monthly charge for new data-center customers under the data-center-specific tariff PUCO ordered in a prior docket. The settlement is the first real-world test of whether that tariff actually holds large-load customers accountable for the distribution costs they create, or whether residential customers continue to absorb the spread.
Ohio Edison and Illuminating Co. Customers of both FirstEnergy utilities began paying higher bills on March 1 under a February PUCO order that spread $245 million in storm-restoration expenses over 25 years rather than the five years FirstEnergy originally requested. Ohio Edison residential customers are paying about 87¢ more per month; Illuminating Co. residential customers are paying $9.67 more per month — a difference that reflects the different cost allocations under each utility's recovery structure. The storm-cost story is not a data-center story directly, but it shows the mechanism by which utility capex lands on residential bills: a PUCO order, a 25-year amortization, and a line item that most ratepayers will not notice until it compounds.
The Powerlines study's top-line number — $1.4 trillion over five years — is not a forecast of spending that may or may not happen. It is the filed capital plans of the utilities themselves, already submitted to state commissions, already moving through proceedings. What it describes is the next wave of rate cases, transmission additions, and cost-recovery filings that every state's PUC will be adjudicating through the back half of the decade. Ohio's April rate decisions are an early sample.
What You Can Do
If you are an AEP Ohio customer:
- The AEP Ohio settlement was approved by PUCO in Case No. 24-875-EL-AIR. Public documents, filings, and the full settlement text are available at puco.ohio.gov — search the case number.
- The Ohio Consumers' Counsel (OCC), the statutorily designated advocate for residential utility customers, is the office to contact with concerns about how the new data-center tariff is applied in practice. OCC accepts public input at occ.ohio.gov and publishes its intervention positions there.
- Any future rate case filed by AEP Ohio will require new PUCO proceedings with a separate public comment window. PUCO publishes case filings and hearing schedules daily.
If you are an Ohio Edison or Illuminating Co. customer:
- The storm-cost amortization order is PUCO Case No. 24-508-EL-AAM (Electric Security Plan / storm deferral). The five-year vs. 25-year amortization question is the one to read in the order.
- OCC also represents FirstEnergy's Ohio residential customers.
If you live in another state:
The Powerlines study covers 51 investor-owned utilities nationally. Your state's public utility commission has the filed capital plans on record. The two questions worth asking at any rate case hearing: (1) what share of this capital is driven by large-load (data center, industrial) customers, and (2) what cost-allocation mechanism ensures those customers pay for it? If the utility's answer is “the tariff is still being designed,” the answer is that residential customers are currently bearing it.
Community Takeaway
The “data centers bring investment” pitch gets its rebuttal on the distribution-rate line of the bill. AEP Ohio's data-center-specific tariff is the right idea on paper — a separate cost class for large loads, with a minimum monthly charge that captures the grid capacity they reserve even when not drawing full power. Whether it works in practice depends entirely on how PUCO applies it across the next three to five years of rate cases. The April settlement is the first real data point.
The Ohio Edison storm-cost spread is the less visible pattern — an 87-cent-a-month increase that no one will protest, compounding across 25 years, recovered from residential customers rather than from the large industrial and commercial accounts that also benefit from grid reliability. When the next wave of $1.4 trillion in utility capex lands in rate cases across every state, the Ohio Edison mechanism is the one to watch for. Small dollar amounts, long amortization windows, and allocation formulas that push costs down the customer hierarchy are how the buildout actually gets paid for — and the customer class with the least leverage absorbs the most of it.
