Torus, a Utah-based energy storage provider and mini power plant builder, has been selected by Rocky Mountain Power as a commercial battery provider, according to a March 19 news release.

The approval means Torus is certified to deploy up to 1.2 megawatts (MW) for grid-scale energy storage systems across the PacifiCorp service territory as part of Rocky Mountain Power’s Wattsmart Battery Program.

“Commercial-scale energy storage is a necessary piece of the grid of the future, and Torus’ solutions have demonstrated their ability to integrate within the Wattsmart battery ecosystem,” said Bill Comeau, vice president of customer experience and innovation at Rocky Mountain Power. “The Wattsmart program creates a more flexible and resilient grid while saving customers money, and Torus has proven their innovative systems can deliver.”

Torus said it is one of only two commercial battery providers to pass Rocky Mountain Power's rigorous testing standards. As stated in the news release, Torus’ systems achieved a 99% uptime score in telemetry testing and met standards set by the Institute of Electrical and Engineers Standards Association regarding communication protocol requirements for fleet-wide unplanned demand response during certification.

“Torus’ Nova Spin flywheel technology, recognized in TIME’s Best Inventions of 2024, delivers a C-rating 10 times higher than traditional batteries and twice the operational lifespan,” according to the release.

The certification approval milestone builds on a January 2025 memorandum of understanding between Rocky Mountain Power and Torus to deploy a 70-MW demand response initiative capable of powering the equivalent of about 20,000 homes using Torus’ Nova technologies, Torus said in the news release.
