Voltus raises $225M Series D to turn homes and batteries into data centre power
Voltus, a San Francisco company that runs a virtual power plant, raised a $225 million Series D led by Generation Investment Management, with Activate Capital and energy trader Vitol as co-leads and Broadscale Group, Climate Investment, NGP, Ajax Strategies and All Aboard Fund also participating. Voltus pays businesses and homes to cut, shift or supply power when the grid needs it, then sells that flexible capacity into electricity markets; it says its platform holds 8.5 GW today and targets 20 GW by 2030 across the US and Canada, and it did not disclose a valuation. The money will expand its Bring Your Own Capacity programme, which includes a three-year June deal with Google for up to 100 MW a year in PJM and an August agreement with Sunrun to supply home solar and battery capacity for Voltus deals with AI hyperscalers.
AI data centres are straining grids, and virtual power plants that aggregate batteries and flexible demand offer an alternative to building more fossil-fuel generation.
Voltus has raised $225 million in a Series D round. The San Francisco company pays businesses and homes to cut, shift or supply power when the grid needs it. Generation Investment Management led the round, with Activate Capital and the energy trader Vitol as co-leads.
Broadscale Group, Climate Investment, NGP, Ajax Strategies and All Aboard Fund also invested. Voltus called the round oversubscribed. It did not disclose its valuation.
“Electricity is now the constraint behind almost every major ambition we have, but it doesn’t have to be,” said Dana Guernsey, Voltus’s chief executive.
