Green Voltis, a Stockholm company that operates and trades battery storage across European power markets, raised €13.5m (about $15.5m) in a Series A round announced on 5 November 2026.
Lochpine Capital, an asset manager focused on the energy transition, was the sole investor. Green Voltis did not disclose a valuation or any earlier funding.
The company said it will spend the money on research and development for its two in-house software systems, on growth in key European markets and on a new business it calls Power-to-Compute, which applies its energy software to data centres.

What Green Voltis does
Battery owners need someone to connect their sites to the grid, run them day to day and sell their flexibility in electricity markets. Green Voltis describes itself as a route-to-market optimiser that handles all of these steps, from grid connection and commissioning through to energy management and power trading. It works with standalone batteries and with renewable plants paired with storage.
The company runs on two systems it built itself. Chronos is an energy management system for battery sites. Aether AI is a trading agent that forecasts electricity prices across markets.
Green Voltis said it has more than 1.2 GWh of storage under contract and in operation, and that it has market access in place or underway in 10 European countries. It also said the assets it manages have consistently performed better than the Clean Horizon index, an independent benchmark for battery storage revenue. That claim comes from the company and was not independently verified in the announcement.
From batteries to data centres
The Power-to-Compute business aims to deliver data centres that work with the grid rather than against it, built with compute partners. Vestbee reported that it is meant to ease the long waits data centre developers face for grid connections. Green Voltis has a pipeline of about 120 MW of powered land in the Nordics for the business.
"Green Voltis will provide the AI energy infrastructure layer between the grid and compute," said Martin Kievit, chief executive and co-founder. He argued that the software that runs a battery can also manage a data centre's energy use, and that data centres need power faster than grids can supply it.
Kievit also said that each new gigawatt of renewable capacity makes Europe's grid harder to balance, which makes flexible assets such as batteries more valuable.
Who is backing it
Lochpine Capital invests in private equity and other asset classes. Its description in the announcement says it draws on China's technology and industrial resources in new energy, and targets battery technology, renewable energy and related industries.
Blake Niu, a partner and head of private equity at Lochpine Capital, said grid connection and power trading are becoming central to the value of energy assets and are among the scarcest skills in Europe's energy transition. He said the firm followed the field for a long time before choosing Green Voltis.
The Green Voltis team includes people who previously worked at Ericsson, T-Mobile, Rolls-Royce, Brady and Varberg Energi, mixing telecoms, cloud and AI experience with power systems and trading. The company did not give its headcount or founding year.
