Moiseus Infrastructure Brief — No. 07
Every week we cut the noise to a handful of stories that matter — and add what they mean from where we sit. This is our read, not a news wire.
Nearly 4,000 MW of data-center load tripped offline in Virginia — the largest such event in PJM history
A July 22 transmission fault in Ashburn, Va. was cleared normally, but data centers across the Dominion zone unexpectedly disconnected and transferred to backup power — dropping roughly 3,800 MW off the system in an instant and spiking voltage and frequency.
The grid’s fastest-growing load class is also its least predictable. A site that rides through a fault instead of walking away from it is worth more to a utility than one that simply shows up with a big number.
Ride-through rules for large computational loads move from guidance to mandate
PJM is evaluating changes to its interconnection reliability requirements after the event — following ERCOT, whose ride-through rules (NOGRR 282) took effect Aug. 1, and FERC, which directed NERC in July to address the issue. NERC’s tally of these load-loss events has climbed steadily since 2023.
This is the same path inverter-based resources walked: voluntary guidance, then reliability guidelines, then enforceable standards. Grid-compliance engineering is becoming a real line item — and a quiet barrier to entry for thinly capitalized projects.
PPL and Blackstone lock in 5 GW of gas turbines for Pennsylvania data centers
The joint venture secured turbine capacity to serve large loads in PJM. Although PJM aims to hold a backstop reliability auction in late September, PPL’s CEO said he expects bilateral contracting to be the main pathway for adding new generation.
Turbine slots, not megawatts on paper, are the binding constraint of this cycle. Whoever reserved manufacturing capacity two years ago now effectively decides who gets to build — and the deals are being struck bilaterally, outside the auction.
FERC sides with demand-response firms, unlocking at least 4.9 GW in PJM
FERC ruled for Voltus and the Mission:data Coalition and against PJM’s smart-meter data rules, finding it “unjust and unreasonable” that the current approach keeps at least 4.9 GW of demand-side capacity — several large power plants’ worth — out of the market.
Regulators are now treating flexible demand as real capacity. The cheapest gigawatt is the one nobody has to build, and it competes head-on with new generation — which sharpens, rather than softens, the premium on firm power that cannot be curtailed.
Vendors begin selling grid compliance as a product
DIMAAG launched a modular grid-to-800 VDC conversion and stabilization platform with immersion-cooled battery storage, independently validated to meet ERCOT’s low-voltage ride-through requirements and to smooth cyclic load swings to under 1% as seen by the grid.
When reliability rules tighten, an equipment market forms around them within months. The cost of being grid-friendly is falling fast — which means the excuse for not being grid-friendly is disappearing just as fast.
Five stories, one signal: the grid has stopped treating large computational load as a passive customer — ride-through, flexibility and self-supplied firm power are becoming conditions of interconnection, not optional extras. The advantage shifts to owners who engineer for the grid instead of around it.
