On-Site Power Is Not Only a Data Center Story

Data centers have stopped waiting for the grid. In an April Bloom Energy survey, about a third of hyperscalers and colocation providers said they expect to be running campuses entirely with on-site power by 2030. Bloom sells on-site power, so that is likely the bullish case, but the overall direction is hard to argue with.

What has gotten less attention is everyone else on the same grid. Manufacturers, food processors, chem plants and large commercial sites are paying for the data center buildout whether or not they ever see one. In PJM, the price of securing future power supply has hit its cap in three straight auctions, and that cost effectively lands on every industrial bill in the region. Equipment is tight too. GE Vernova is already selling turbine delivery slots for 2031. And the new rules PJM is writing for large power users do not stop at data centers. A plant that adds enough new load gets caught by them as well.

That does not mean most plants will build their own power (they probably will not). But a meaningful slice will: big sites that run around the clock, cannot afford outages, or are planning to expand. Bloom says demand from its commercial and industrial customers remains strong alongside its data center business. For everyone else, on-site power will look smaller. Solar and batteries to shave peak costs, better backup, and a harder look at utility contracts.

For companies that sell into this market, that is worth watching. Data center buyers are few and enormous, and they tend to buy the same way. C&I buyers do not. A 20 MW food plant and a 200 MW chemical complex do not have the same problem or the same budget, and neither looks like a hyperscaler's procurement team. They need smaller systems, financing, long-term service, and someone who can explain the tradeoffs. A product line and sales approach built for data centers will not automatically carry over.
