STOCKHOLM, 5, November – Green Voltis, a Stockholm-based route-to-market (RTM) optimiser that uses AI to operate and trade battery storage across European power markets, today announced it has raised €13.5 million in a Series A round, with Lochpine Capital as the sole investor. Green Voltis optimises standalone battery storage and co-located renewable-plus-storage projects, with more than 1.2 GWh under contract and in operation.

Europe is building battery storage faster than ever, but owners keep running into the same problems. Grid connection is getting slower and more complex, and new grid-forming requirements have added another hurdle that many control systems were not built for. Prices across day-ahead, intraday and balancing markets now move every 15 minutes, which makes revenues hard to predict and projects harder to finance.

Green Voltis covers the full path from grid connection to trading. Its engineering team handles hot commissioning and prequalification for ancillary services, so projects start earning sooner. Chronos, its energy management system designed in Sweden, controls the site, is certified against grid codes and supports grid-forming operation. Aether AI, its trading agent built on time-series foundation models, forecasts prices and stacks revenue and capacity across several markets at the same time, rather than committing a battery to one market at a time. On top of this, Green Voltis offers bankable commercial structures, including revenue sharing, tolling and revenue floors, that help owners secure project finance.

Assets managed by Green Voltis have consistently outperformed the Clean Horizon index, an independent benchmark of battery storage revenues. The company has market access in place or underway in 10 European countries.

Green Voltis is now applying the same capabilities to AI infrastructure. In Europe’s main data centre hubs, a grid connection can take seven to ten years, and regulators from Ireland to Finland are starting to require new data centres to provide flexibility to the grid. Through its Power-to-Compute business, Green Voltis aims to connect the grid on one side and compute on the other, running data centre sites as grid-friendly flexible assets so that compute can get 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 be used to expand R&D on Aether AI and Chronos, grow the business in key European markets, and build out the company’s Power-to-Compute business.

The Green Voltis team brings together people from Ericsson, T-Mobile, Rolls-Royce, Brady and Varberg Energi, among others, combining experience in telecoms, cloud and AI with power systems and power trading.

Martin Kievit, CEO and co-founder of Green Voltis, said: “Every new gigawatt of renewables makes Europe’s grid harder to balance, and flexibility now sets the pace of the energy transition. We built Aether and Chronos to turn storage and renewable plants into assets the grid can rely on and investors can bank on. The next wave of demand comes from AI. Data centres need power faster than grids can deliver it, and the intelligence that operates a battery can also manage a data centre’s energy. Green Voltis will provide the AI energy infrastructure layer between the grid and compute. With Lochpine Capital as a long-term partner, we are ready to build it.”

“As renewables take a larger share of the energy mix, grid connection and power trading are becoming key to the value of energy assets, and they are among the scarcest capabilities in Europe’s energy transition,” said Blake Niu, Partner and Head of Private Equity at Lochpine Capital. “We followed this field for a long time before choosing Green Voltis. The team combines AI-native technology with a global industrial perspective, and its operating results, which have consistently beaten the industry benchmark, show what it can do. We believe Green Voltis can become a leading operator of flexible energy assets in Europe and create greater value where AI and energy meet.”
