Stockholm’s Green Voltis raises €13.5 million to operate and trade battery storage across European power markets using AI
Green Voltis, a Stockholm-based route-to-market optimiser that uses AI to operate and trade battery storage across European power markets, has raised €13.5 million in a Series A round. Lochpine Capital is the sole investor. Founded in 2024 by Martin Kievit, Ali Shi and Gino Zhang, the company optimises standalone batteries and co-located renewable-plus-storage projects, with more than 1.2 GWh under contract and in operation. It has market access in place or underway in 10 European countries.
The company says grid connections are slowing and getting more complex, and that new grid-forming requirements are a hurdle many control systems were not built for. Prices in day-ahead, intraday and balancing markets now move every 15 minutes, which makes revenues hard to predict and projects harder to finance. Green Voltis says it covers the full path from grid connection to trading. Its engineers handle hot commissioning and ancillary-services prequalification so projects earn sooner. Its Swedish-designed energy management system is certified against grid codes and supports grid-forming operation. Its trading agent, Aether AI, is built on time-series foundation models and forecasts prices, stacking revenue and capacity across several markets at once instead of committing a battery to one. It also offers revenue sharing, tolling and revenue floors to help owners secure project finance. The company says its managed assets have consistently beaten the Clean Horizon index, an independent benchmark for battery storage revenues.
Green Voltis is now applying the same capabilities to data centres. In Europe's main hubs, grid connections can take seven to ten years, and regulators from Ireland to Finland are starting to require new data centres to provide grid flexibility. Its Power-to-Compute business aims to run data centre sites as flexible, grid-friendly assets so compute gets power sooner. It has a pipeline of around 120 MW of powered land in the Nordics and will partner with compute operators to develop it.
The funding will go to R&D on Aether AI and the Chronos energy management system, growth in key European markets, and building out Power-to-Compute. Lochpine's Blake Niu said grid connection and power trading are becoming key to the value of energy assets, and that he believes Green Voltis can become a leading operator of flexible energy assets in Europe.
