The deal
AEP will take an initial 190 megawatts in 2027, with an option for 200 megawatts a year through 2034, Bloomberg reported. Mainspring values the agreement at more than $4 billion.
Why it matters
Utilities are turning to on-site generation because grid connections for new data centers can take years. What to watch: whether other utilities sign similar orders, and how regulators treat the cost of these units in customer rates.
