Arenko has launched its international expansion programme with the rollout of its AI-enabled Nimbus software platform across battery storage assets in the US, Germany and Ireland.
The move follows the company’s £9m fundraise earlier this year and marks a major milestone in Arenko’s growth, extending its energy optimisation technology from the UK to high-growth North American and European markets.
Nimbus, which processes around five billion data points per day, provides real-time optimisation and digital infrastructure for battery energy storage systems, helping owners and operators maximise returns while improving grid stability and resilience.
Arenko founder and chief executive Rupert Newland said: “This expansion is a pivotal moment for Arenko. Built and proven in the UK, one of the world’s most advanced and volatile energy markets, we are now taking our proven expertise to the global stage. Our mission is to provide the digital backbone for the zero-carbon grid. By partnering with asset owners in North America and Europe, we are delivering tangible improvements in grid stability, renewable energy profitability, and the overall pace of the energy transition. This expansion demonstrates that our technology is not just scalable, but essential for de-risking investments and maximising returns in the new energy landscape.”
The expansion includes deployments across three Texas-based battery projects – Sweetwater, Snyder and Westover – with a combined capacity of 30MW, as well as the 22MW Cremzow project in Germany and two additional assets in Ireland.
Arenko said use of Nimbus has delivered average EBITDA improvements of around 21% while reducing capital and operating costs for site owners.
The company’s expansion underscores the UK’s growing influence in global clean energy technology, with Arenko’s software already supporting major international operators including RWE, Ørsted, Vattenfall, ElectroRoute and Gore Street Energy Storage Fund.
