The Big Story
Google signs up for a gigawatt of virtual power plant capacity

Google signed an expanded "bring your own capacity" contract with Voltus for a 1,070 MW virtual power plant in PJM, Latitude Media reported. The VPP will offset load from multiple Google data centers in the region, and batteries are expected to play a significant role.

"We're actually creating a market where they don't need to take merchant risk anymore because we have the longer-term contract here."

  • The contract runs through 2040, Guernsey confirmed. Other terms are not public.

  • It builds on the more than 100 MW Voltus developed for Google in PJM this summer, which Guernsey said was "over-subscribed."

  • Behind-the-meter commercial and industrial batteries will make up "a chunk" of the portfolio, alongside some residential batteries through partners like Sunrun.

  • Most VPP deployments to date have been in the hundreds of megawatts, according to Latitude Media.

The Capital Stack
GM leads a $108 million bet on sodium-ion grid storage

Peak Energy closed a $108 million Series B led by General Motors Ventures, with Maverick Silicon, Eclipse, Infinite Capital, Xora Innovation and LG Technology Ventures joining, Energy Monitor reported. The startup makes passively cooled sodium-ion storage for grid and data center use and says the money will expand US manufacturing and help fill more than $1 billion in existing customer orders. Its planned 4 GWh factory in Sacramento is slated to begin production in the first quarter of 2027.

Also in the capital stack:

DOE selected 63 tribal energy projects across 16 states for more than $125 million, the largest round in the Office of Indian Energy's history, including electrifying 150 homes without power. The projects are selected for award negotiation. U.S. Department of Energy

Policy Watch

  • New York regulators have ordered utilities to file inventories of how they use AI, and Connecticut has petitioned for a similar review. Guardrail found 70% of energy and utility filers name AI as a cyber risk, but only 23% of utilities document a process to manage it, so AI tools for load planning now face audit trails. Utility Dive

  • The Commerce Department has blocked about 60 solar importers in recent weeks while approved importers grew from about 200 to more than 400, according to Roth analyst Philip Shen, Heatmap reported. The 120-day runway before Section 232 polysilicon tariffs ends Dec. 3, and utility-scale carveouts are "not being worked on," which leaves developers sourcing 2027 modules little room. Heatmap
