BVES statement: Modernize the grid connection process NOW!
The German Energy Storage Systems Association welcomes TenneT’s intention to modernize the grid connection process! However, forward-looking planning is crucial. Those who only plan switch panels according to current needs will always be lagging behind in terms of grid expansion.

TenneT was also right to raise the issue of construction subsidies. The current regulations create false incentives and systematically disadvantage storage facilities—not only in the north, but nationwide. A sustainable electricity market can no longer afford this.
Expansion areas & prioritization
It remains unclear why network operators are not proactively securing expansion areas—after all, the increasing demand for infrastructure has been known for a long time, not just since yesterday. We therefore believe that the idea of prioritizing connection requests is fundamentally correct. However, this must not trigger technology wars. Storage facilities should be ranked above end consumers. This is the only way to reduce electricity costs and relieve the burden on grids. Non-discriminatory procedures are not a “nice to have” but a must. The procedure planned by 50Hertz has already shown how quickly storage facilities can be unfairly disadvantaged.
Regarding KraftNAV: Not a total failure for storage, but not a perfect fit either. Together with the industry, we are ready to help develop a more tailored approach. However, abolishing it at short notice without a replacement would cause further uncertainty and significantly slow down the ramp-up of storage.
Grid fees: Yes to costs, no to investment killers
The same principle must apply to grid fees: yes to cost reflection, no to investment killers. The storage market is still in its infancy: just around 2 GW are currently connected to the grid. Tightening the fee screw now would nip growth in the bud.
Flexibility is key for the renewable energy system: Flexible grid connections enable more storage in the grid, measurably reduce the load on it—and all without compensation payments to operators. #FLEXILLIENZ
