From Concept to Impact: How REGIOlink Stabilizes Regional Grids with Large-Scale Battery Storage
The energy transition is considered one of the largest infrastructure projects of our time. Yet while the national electricity market often dominates the debate, one crucial question is still too rarely asked: How can storage solutions be operated in a way that makes them not only efficient in the electricity market, but also effective at the regional level? A project in the Allgäu region is now providing answers.

"REGIOlink" concept for regional grid support – first implementation already underway
With its “REGIOlink” model, green flexibility has developed a practice-oriented and cooperative concept for regionally grid-supportive operation of large-scale battery storage systems. While terms like “grid-supportive” or “grid-neutral” are currently widely discussed, a uniform and regulatory clear definition is often missing. This is exactly where the white paper (in German) by the Research Center for Energy Economics (Forschungsstelle für Energiewirtschaft, FfE) comes in.
