Acton Energy develops, builds, owns and optimizes grid-scale battery storage in Europe, starting in Germany. As a next-generation independent power producer, we keep every asset we build and run it for the grid, every quarter hour.
The German storage market splits its roles: developers sell, contractors build, traders optimize assets they do not own. We integrate all three, because the value compounds when they sit under one roof.
We develop proprietary project rights and acquire projects from the market. What enters the portfolio stays in the portfolio: we do not flip projects. Ownership keeps every incentive long term, from site selection through the last operating year.
We take each project through construction, grid connection and commissioning, then operate it for the long term. Our two current builds, Lauta (40 MW) and Plettenberg (30 MW), follow exactly this path.
We market each asset's flexibility across balancing reserves (FCR and aFRR), day-ahead and intraday arbitrage on quarter-hour products and further system services. Stacking these markets and shifting between them as prices move is how an owner earns more than a landlord.
The first generation of power producers burned fuel. The second harvested wind and sun. The third produces flexibility: it stores surplus electricity and releases it when the grid needs it. The full argument is on our homepage; the numbers behind it are below.
of renewable electricity was curtailed in Germany in 2024. Wind and solar plants were switched off while the energy was needed elsewhere. Storage converts that surplus into supply.

of stationary battery storage is what Fraunhofer ISE estimates Germany needs by 2030, rising to around 180 GWh by 2045. Today's installed base covers only a fraction of that.

are the horizons of Germany's grid development plan. Its scenarios depend on large-scale flexibility to balance a renewable power system, with grid-scale batteries as a central option to provide it.

A portfolio is only as strong as its inflow. We source projects through four independent channels, so no single market condition can stall our growth. Exclusive framework agreements with established German project developers secure a predictable inflow of ready-to-build projects on top of our own development work.
We acquire projects and project rights where sellers need speed and certainty. That requires fast underwriting: we assess, decide and close quickly.
Our own team develops large grid-scale sites from origination to ready-to-build status. Six proprietary projects totalling 960 MW are advancing today.
Smaller, standardized storage units deployed close to demand and to distribution grids. Standardization keeps unit costs, permitting and timelines predictable and repeatable.
We develop storage together with industrial energy users on their sites, combining value for the grid with value behind the meter.
The dates for 2027 and 2029 are targets and we treat them that way: openly stated, tracked and updated. Every project behind this roadmap is listed by name, location and size on our Projects page.
