WeStorix® Green Power Station
Grid-forming power for a renewable grid
WeStorix develops and operates Green Power Stations - large-scale energy storage hubs with grid-forming power conversion that connect renewable energy and major electricity users behind a single grid connection.
More renewable power used. More capacity for industry. A stronger grid.
The challenge
Grid capacity is now the bottleneck of the energy transition
Across Denmark and Europe, renewable projects and new industrial demand are queuing for grid connections that will take years to build. At the same time, the retirement of conventional power plants removes the inertia and voltage support that keep the power system stable.
Our answer
The Green Power Station
A Green Power Station combines a high-voltage substation, a BESS with grid-forming power conversion and at least four hours of energy storage. Renewable producers and large consumers connect to it by direct line and share one grid connection, optimized around the clock. The result: more renewable power used locally, more capacity for industry and stronger support for the public grid.
How it fits together
One connection point. Large producers and consumers. One optimized system.
Text description of this illustration
The public transmission grid connects by a high-voltage connection to the high-voltage substation inside the Green Power Station. The substation feeds a medium-voltage busbar, and the BESS is connected to that busbar: a grid-forming Power Conversion System and energy storage based on LFP battery technology. Direct lines start at the busbar inside the station and run to renewable generation, industry, a data center and transport charging. The WeStorix Energy Management and Trading Center controls the station around the clock.

Our response on flexible grid access
WeStorix has responded to the Danish Energy Agency's consultation on flexible grid access. Storage-led Energy Hubs are well suited to it.
Why data centers can be grid-friendly
Data centers are usually judged on peak demand alone. Inside an Energy Hub, they can reduce their load on the grid and support it.
