Switched On: Entrix Hits 3GW With a €43M Jolt

Munich's Entrix raises €43M and locks in 3GW of battery contracts across five European markets, with 2GW going live this year

Electricity grids have always disliked surprises. Too much power at noon, too little at dusk, and the consequences range from costly to catastrophic. For most of the past century, operators managed this with brute force: build more cables, burn more gas, hope for the best. That model is fraying, and a small firm in Munich thinks it knows what comes next.

Entrix, founded in 2021, has this week closed a €43m funding round and crossed 3 gigawatts of contracted battery storage capacity across five European markets. Two gigawatts are due to be operational before the year is out. At that scale, its portfolio could, in theory, meet the peak electricity demand of roughly three million households.

Junction Growth Investors and Korys led the round, joined by BNP Paribas via its Solar Impulse Venture Fund, Allianz, AENU, Enpal, Abacon, and Arvantis Group. Allianz's involvement is the detail that matters most. When insurance capital moves into battery storage, it signals that revenues underpinning the sector are no longer considered speculative. Conservative institutional money does not chase yield curves; it follows contracts.

Operating more than 70 battery systems across Germany, Italy, Spain, Poland, and Portugal, Entrix uses artificial intelligence to dispatch stored energy in real time, reading price signals, balancing service needs, and intraday market conditions at once. Germany is its largest market. Poland is its fastest-growing one, where structural shifts in the country's energy mix are opening flexibility markets that barely existed two years ago.

Steffen Schülzchen, founder and chief executive, frames the moment in sweeping terms. Volatile fossil fuel prices, surging data-centre demand, and rapid renewable deployment are, he argued, creating grid conditions that traditional infrastructure cannot manage alone. "Batteries dispatched by intelligent software," he stated, "are no longer optional."

Harder to answer is whether the business scales. Five distinct regulatory regimes bring five different approaches to flexibility services. An AI optimisation system that works well across 70 batteries must prove equally effective across 200. That is the test Entrix now faces, and investors, for the moment, seem willing to pay for the answer.
