Green Voltis raises €13.5 million for AI-driven grid assets

By Amara Osei

Stockholm-based Green Voltis has raised €13.5 million in a Series A round led solely by Lochpine Capital, with more than 1.2 GWh of battery capacity under contract and in operation.

Green Voltis develops AI-powered route-to-market (RTM) optimization technology for battery storage and renewable energy assets. The company says its platform helps operators manage grid connections, control energy systems and trade electricity across European power markets.

What does the €13.5 million fund?

Green Voltis will use the proceeds for further research and development of Aether AI and Chronos, expansion in key European markets, and development of its Power-to-Compute business. Lochpine Capital was the round’s sole lead investor.

Green Voltis says Aether is an AI trading agent that forecasts electricity prices and optimizes revenue across multiple power markets. It uses time-series foundation models to coordinate trading and combine opportunities rather than commit battery capacity to a single market.

Green Voltis says Chronos controls on-site operations, supports grid-code compliance and enables grid-forming functionality. The system manages batteries and renewable plants while helping operators meet grid requirements.

How does Green Voltis turn storage into a bankable asset?

Green Voltis provides grid connection, commissioning, market access and commercial services across the asset lifecycle. Its engineering team handles hot commissioning and prequalification for ancillary services, helping storage projects enter the market.

The company offers revenue sharing, tolling agreements and revenue floors. Green Voltis says those structures are intended to provide more predictable income for asset owners and support project financing.

Green Voltis operates across 10 European markets and has market access established or under development in 10 European countries. The company says the battery assets it manages have consistently outperformed the Clean Horizon index, an independent benchmark for battery-storage revenue.

Green Voltis said the investment arrives as Europe’s battery-storage capacity expands and its trading environment becomes more complex. Operators must manage grid-connection requirements, technical standards and price swings across day-ahead, intraday and balancing markets as electricity prices change at 15-minute intervals.

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.”

Can AI data centers become flexible grid assets?

Alongside battery storage, Green Voltis is developing Power-to-Compute for AI infrastructure’s growing energy requirements. The company points to lengthy grid-connection timelines in some of Europe’s main data-center hubs, where connections take an estimated seven to 10 years.

Green Voltis says regulators in countries including Ireland and Finland increasingly require new data centers to provide flexibility to the electricity grid. Its model treats data-center sites as flexible energy assets by linking grid infrastructure with computing capacity so operations can respond to grid conditions.

Green Voltis has identified approximately 120 MW of powered land in the Nordic region. The company plans to develop the opportunity in partnership with compute operators.

“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.”

The next milestone is a partnership that activates part of the approximately 120 MW Nordic powered-land pipeline while Aether and Chronos advance in additional European markets. That execution will test Green Voltis’s claim that one operating layer can manage batteries, electricity markets and grid-responsive data-center demand.
