Electron, a GridTech company based in the United Kingdom, has agreed to acquire Rhythmos.io, expanding its operations into the U.S. Electron helps provide a marketplace for distributed energy resource (DER) providers, including those like Rhythmos.io, which is a company that offers solutions for EV fleets and utilities manage their electricity usage.

"DERs have the potential to unlock significant system-wide savings by optimizing both energy use and grid infrastructure, and our experience running flexibility markets internationally shows these benefits are real and scalable," said Jo-Jo Hubbard, CEO of Electron. "The challenge isn't on the supply side—virtual power plants have already aggregated gigawatts of flexibility. The challenge lies on the buy side: utilities need better visibility, valuation tools, and market capabilities to build defensible business cases for relying on DERs at scale. With Rhythmos, we're bridging that gap by bringing grid awareness to flexibility markets, which helps both utilities deploy resources more strategically and DER providers capture more value."

According to the companies, their combination will help utilities find and measure the impact of EVs and batteries on specific transformers and substations across their network, providing greater visibility into these systems. Additionally, this will provide data that utilities can use for regulatory purposes.

“For the first time, utilities can cost-effectively see precisely where distributed resources exist and how they affect the grid—right down to the service transformer using data they already have,” said Ken Munson, CEO of Rhythmos. “By pairing Rhythmos’ grid-edge visibility with Electron’s flexibility marketplace, utilities gain the situational awareness needed to make smarter, data-driven investment decisions.”

According to the two companies, the transaction terms were not disclosed. The acquisition is expected to close next month, subject to customary conditions.
