Power deals are getting harder to sell—and somebody’s finally drawing the liability lines. This is The Data Center Daily. Today, we're looking at the structures meant to protect the grid when giant loads change their minds. We’ll start with the ringfence, then get to exit fees and a Chicago office conversion with an $82 million entry ticket. Here's Bianca Giacobone at Latitude Media:
The idea, the analyst laid out, is to wall off all the generation a new data center might need, so it’s not owned by the parent utility directly and therefore regular ratepayers don’t finance any of it — and therefore are not exposed to risks if things go south.
Here’s how Latitude’s GenCo works: NIPSCO Generation owns dedicated supply and sells it to NIPSCO under a PPA, while Amazon and Alphabet sit on the load side. Existing customers are supposed to stay outside that financing chain. “Supposed to” leaves a lot hanging. If those Amazon or Alphabet commitments soften, that GenCo owns generation built for a customer who may no longer need it—and then we find out whether the ringfence is steel or drywall. And NIPSCO is still the only utility that’s actually done this, per Latitude. Approval came in September 2025; everybody else is interested, but nobody else has an operating structure. I’ll give it this: putting dedicated generation in a separate affiliate is a more grown-up answer than asking a legacy utility balance sheet to gamble on a hyperscaler’s five-year planning model. But the contracts have to survive the bad case. From Brian Martucci at Utility Dive:
More utilities are asking prospective large-load customers to pay upfront for system impact studies, ramp up to full load within a set number of months and pay an exit fee if they stop or significantly reduce service before their contract expires, according to a recent technical brief prepared by researchers with Lawrence Berkeley National Laboratory and the Brattle Group.
Halcyon counted 264 large-load tariff filings by August 17. Utilities have stopped treating a 500-megawatt customer like a very enthusiastic mall. The LBNL-Brattle brief spells it out: pay for the system-impact study upfront, ramp to contracted load on schedule, and pay an exit fee if you shrink early. Those are underwriting inputs, not regulatory garnish. Good. But an exit fee has to cover more than somebody’s study invoice. If the utility commits transmission and generation around a giant load that vanishes, the fee needs to reach the stranded steel. NIPSCO’s GenCo ringfence handles the ownership side. On the tariff side, it’s contracts, collateral, and minimum billing demand—with fewer chances to socialize a customer’s change of heart. Here's Dave Mueller at Utility Dive:
Today's AI training campuses are not simply larger versions of traditional data centers. With proposed loads reaching 1,000 MW or more, they represent a new category of grid-connected customer whose size and electrical behavior challenge many longstanding planning assumptions.
A 1,000-megawatt AI campus that can swing hundreds of megawatts in seconds isn’t the nice, flat industrial load planners grew up modeling. You don’t get to plug that into the grid as a static spreadsheet cell and call it studied. EnerNex gets at the technical side of the tariff conversation: conventional interconnection studies were built for stable blocks of demand. AI training loads start, pause, checkpoint, and change the grid picture while the study assumptions are still sitting there. Right—and power-electronic gear reacts faster than the old planning models expect. Before anybody blesses a multi-hundred-megawatt campus, run the EMT studies, validate the equipment models, and make sure it can ride through a disturbance without throwing a tantrum across the system. The GenCo can ringfence the money, and an exit fee can ringfence the contract. Neither fixes a facility that behaves electrically unlike the customer the utility thought it was connecting. Here's Sawdah Bhaimiya at CNBC:
Verdant, which advocated for tighter controls on data center development, estimates that existing U.K. data centers support about 4,400 direct jobs, compared with techUK's estimate of 24,300. For planned developments, Verdant projects about 10,400 permanent operational jobs by 2035 — roughly a quarter of techUK's forecast of 40,200 roles.
TechUK sold policymakers 8.5 permanent jobs per megawatt. Verdant looked across 20 facilities and got 1.2. That’s a very expensive rounding error when a town is being asked to allocate power and land. Verdant puts planned U.K. sites at roughly 10,400 permanent operational roles by 2035, versus techUK’s 40,200. The government has used the higher figures while approving development. Older, smaller facilities need more people; hyperscale campuses tend to need fewer. Construction jobs count, sure. But permanent jobs are the promise that stays after the cranes leave. If the operating footprint is 1.2 jobs per megawatt, planning boards need to quit treating a gigawatt campus like a giant local employer. The tariff protections we just covered need equally specific math on the public-value case, too. “Career paths” is not a staffing model. Commercial Real Estate Direct’s Dan Moynihan is tracking this. Digital Realty just paid $82 million for 485,000 square feet in Rolling Meadows—$169 a foot—for an office building that likely still needs its power-and-cooling plan figured out. Twenty-five miles from Chicago, and the purchase price is just the start. Conversion economics now hinge on interconnection, the cooling plant, and how quickly usable megawatts can actually arrive. And after what we just covered on tariffs, that timeline comes with a price. Study payments, the cost of missing a ramp schedule, and exit exposure all add up—buying cheap-ish office space is one thing; carrying a half-converted building while the grid catches up is another.
