ElectroRoute selects Arenko’s Nimbus software to support entry to the UK BESS market

ElectroRoute, a renewable energy trading company and subsidiary of Mitsubishi Corporation, has agreed a strategic software partnership with Arenko that will facilitate its entrance to the UK Battery Energy Storage System (BESS) market. Under this new agreement, ElectroRoute will licence Arenko’s Nimbus Trade software to optimise and operate its fast-growing UK battery portfolio.

Nimbus Trade will be seamlessly integrated with ElectroRoute’s existing trading desk and proprietary CORE Platform, enabling its dedicated 24/7 in-house trading team to efficiently trade and optimise battery assets. The platform will provide a highly sophisticated suite of automation capabilities across market access, asset control and dispatch, and optimisation.

ElectroRoute has built an impressive market position across Ireland, Japan and the UK. With the recent announcement of over 0.5GW of solar balancing contracts in the UK, ElectroRoute now trades and optimises over 3GW of renewable and flexible assets globally. The adoption of Nimbus Trade highlights ElectroRoute’s commitment to leveraging cutting-edge technology to drive innovation and operational excellence within the UK BESS sector.

This new partnership marks a significant milestone for Arenko taking it to over 2.5GW of BESS and renewables contracted across their Nimbus product suite, demonstrating the market’s growing confidence in Nimbus.

Arenko’s Nimbus software suite delivers robust digital infrastructure for large energy companies, enabling standardised, data-driven operations across renewable energy assets and markets. It supports automated trading, asset management, and back-office functions – empowering organisations to drive digitalisation, scale efficiently and maximise asset value.

Rupert Newland, Founder and CEO of Arenko Group, said: “We are delighted to be supporting ElectroRoute with their exciting UK BESS expansion. They have a proven track record of strong performance and growth. This is further evidence of the bankability of our Nimbus software with top tier trading houses and big energy companies.”

Brian Kennedy, Chief Commercial Officer of ElectroRoute, said: “We are thrilled to partner with Arenko and integrate their cutting-edge Nimbus Trade software into our operations as we expand into the UK BESS market. This collaboration underscores our commitment to leveraging innovative technology to optimise our growing battery portfolio and deliver best-in-class energy trading solutions.  By combining Arenko’s advanced automation capabilities with our in-house expertise, we are well-positioned to accelerate our mission of making net zero a reality and maximising value for our clients.”
