Google and Voltus Expand PJM Virtual Power Plant to 1 GW

The deal matters because it treats flexibility as capacity that a data-center developer buys, instead of waiting for a new plant or line. Canary Media reported that PJM's cost of securing peak-demand power has risen more than eightfold in a few years, and that the grid operator forecasts 30 to 34 GW of new large-load demand by the early 2030s, driven by data centers. PJM is also struggling to bring new plants online because of its clogged interconnection queue. A virtual power plant needs no construction.

What the contract includes

Voltus CEO Dana Guernsey told Canary Media the company is securing commitments from customers to cut use or supply battery power through 2040. That is far longer than typical demand-response participation: PJM's annual capacity auction secures resources only three years ahead. Guernsey said the long term lets Google show utilities and state regulators that the capacity will persist, and gives customers contracted revenue to justify installing batteries.

She also said the gigawatt is in addition to what Voltus already bids into PJM's capacity market, and that Google has committed to 100% carbon-free capacity from the program, with no fossil backup generators. Voltus says it manages more than 9 GW of demand response and virtual power plant capacity nationally, targets 20 GW by 2030 and raised $225 million earlier this month.

Where it sits in PJM's data-center debate

Earlier this month federal regulators rejected PJM's plan to require new data centers to bring their own capacity or risk being cut off during emergencies, Canary Media reported, on the grounds that it interfered with state authority over retail utility operations. As Voltgrid reported, FERC approved the load registry but rejected the curtailment plan. The Google and Voltus deal is a voluntary route to the same goal: new capacity paid for by the load that causes the need.

Canary Media noted that Google is still the only developer Voltus has publicly partnered with on this approach.

What is not confirmed yet

Google has not shared a timeline for the gigawatt, and neither company has said which existing or planned data centers in PJM territory the capacity would offset. Contract terms are not public. Reports also differ on framing: Google calls the project a 10-fold expansion to 1 GW, while the Voltus release describes 1,070 MW as additional to the original 100 MW. Whether PJM and state regulators will count the capacity toward the data centers' obligations is the next test.
