Why the Funding Matters

Voltus will use the funding to expand its platform toward a target of 20 GW by 2030. The company also plans to advance its BYOC program in the PJM and MISO electricity markets and strengthen its position across the United States and Canada.

The investment comes as electricity demand is expected to rise. According to the company’s announcement, the North American Electric Reliability Corporation (NERC) expects peak demand to grow 24% over the next decade, more than twice the growth forecast it made two years earlier.

Who founded Voltus?

Voltus was founded in 2016 by Dana Guernsey, Matthew Plante, and Neil Lakin. The company is headquartered in San Francisco, California.

It operates a distributed energy resource technology platform and virtual power plant service that helps commercial and industrial customers and energy partners earn value from flexible electricity capacity.

“As electricity demand rises, the fastest, most cost-effective and lowest-carbon source of new capacity is often the one already connected to the grid,” said Dave Easton, Partner, Growth Equity, Generation Investment Management.

Market and Business Growth

Voltus works with businesses and distributed energy resource partners to connect flexible electricity loads, power generation, energy storage, energy efficiency, and electric vehicle resources to electricity markets.

Its platform coordinates energy resources that can respond to market needs, helping customers manage energy costs while supporting grid reliability.

The company aims to expand its platform to 20 GW by 2030 and grow its presence across the United States and Canada. The announcement does not provide specific revenue or customer growth figures.
