Green Voltis raises €13.5M Series A to trade Europe’s batteries
Green Voltis raised €13.5 million from Lochpine Capital to trade batteries with AI, as SolarPower Europe forecasts annual European storage installs quadrupling to 138 GWh by 2030.

Stockholm, Sweden
Stockholm-based Green Voltis has raised €13.5 million in a Series A from Lochpine Capital to fund R&D on its Aether AI and Chronos platforms, grow in key European markets and build its Power-to-Compute business.
Europe’s grid gets harder to balance with every wind and solar farm it connects, and a Swedish software team has just raised €13.5 million to operate the batteries that help. Below, I lay out the round, the company, the market and what the deal says about where storage money is going.

€13.5 million from Lochpine Capital for a Stockholm battery trader
Green Voltis announced its Series A on 5 November 2026 in a post on its own site, and ArcticToday carried the news the same day. Lochpine Capital is the only investor named. It is a global asset management platform focused on the energy transition, investing across private equity and other asset classes.
The company says the money will go to research and development on Aether AI and Chronos, growth in key European markets and the build-out of Power-to-Compute. Martin Kievit is CEO and co-founder; the announcement names no other founders.
Blake Niu, Partner and Head of Private Equity at Lochpine Capital, said “the team combines AI-native technology with a global industrial perspective.” That team includes people from Ericsson, T-Mobile, Rolls-Royce, Brady and Varberg Energi, with backgrounds in telecoms, cloud, AI, power systems and power trading.
Aether AI splits one battery across several power markets
Green Voltis calls itself an AI-native “route-to-market” optimizer, meaning it operates and trades battery storage and other flexible assets across European power markets for their owners. Its trading agent, Aether AI, is built on time-series foundation models. It forecasts prices and stacks revenue and capacity across several markets at once, so one battery can earn in more than one market at the same time.
Chronos is an energy management system designed in Sweden, certified against grid codes and able to support grid-forming operation. The engineering team also runs hot commissioning and ancillary-services prequalification. Deals come as revenue sharing, tolling or revenue floors, which the company presents as a way to help owners secure project finance.
The scale figures are the company’s own. Green Voltis says it has more than 1.2 GWh under contract and in operation, market access in place or underway in 10 European countries, and about 120 MW of powered land in the Nordics for Power-to-Compute. It also says its managed assets have consistently outperformed the Clean Horizon battery storage revenue index, a claim we have no independent data to test.
Power-to-Compute connects the grid to compute by running data centers as grid-friendly flexible assets, in partnership with compute operators. “The next wave of demand comes from AI,” Kievit said.
36 GWh installed in 2025, 138 GWh a year forecast for 2030
Europe installed 36 GWh of battery storage in 2025, up 48% year on year, and operational capacity passed 100 GWh, according to SolarPower Europe’s European Market Outlook for Battery Storage 2026-2030 (June 2026), published via Battery Storage Europe. The report forecasts annual installs above 50 GWh in 2026 and 138 GWh in 2030, a fourfold increase on 2025, with utility-scale projects at about 75% of installed capacity by 2030. Investment reached €17 billion in 2025, up 20%, per the same report as summarized by EES Europe on 30 June 2026. By our calculation from SolarPower Europe’s figures, that climb from 36 GWh to 138 GWh works out to roughly 31% a year over 2025-2030.
“Every new gigawatt of renewables makes Europe’s grid harder to balance,” Kievit said. Each new battery also needs someone to decide which market it serves. That growth adds owners who need an operator, and Green Voltis presents its tolling and revenue floors as a way to help them secure project finance.
Two recent Series A rounds in our funding data give the amount its scale. Epyr raised €15 million for thermal energy storage in a round led by SlateVC on 13 October 2026. Furo raised €4 million for industrial battery storage, led by TQ Ventures, on 11 September 2026. Green Voltis lands just below Epyr and at more than three times Furo.
A transition investor backs Nordic battery software
Across these three deals, storage money went to both hardware and software. Epyr and Furo raised for storage technology, Green Voltis for the software and trading on top of it.
The investor also stands out. Lochpine is an energy-transition asset manager, and its Head of Private Equity, Blake Niu, pointed to the team’s industrial perspective alongside its technology. Chronos is designed in Sweden, and the powered land sits in the Nordics.
What the next gigawatt-hours will show
What happens to the Clean Horizon outperformance claim once Europe adds more than 50 GWh of new batteries a year? I will also be watching whether revenue floors and tolling help owners close project finance, and whether compute operators sign up to run data centers on the grid’s terms.
Batteries help balance a grid when someone runs them across several markets at once. Green Voltis now has €13.5 million and a transition investor behind it to show its software can do that job at European scale. Let’s build that operating layer here, from Stockholm outward!
