We recently caught up with Georg Gallmetzer, managing director of German BESS platform Eco Stor, about the firm’s role in formulating flexible connection agreements (FCAs) and how this was intimately tied to the debate on grid fees. 

A roundup of some of our key takeaways from the Energy Storage Summit Germany this week, including around FCAs, inertia, the capacity market (CM), EU restrictions on China, and the future of one very notable system integrator.

Flexible Connection Agreements (FCAs) must not be used simply to exclude BESS from connecting to the grid, but the industry will have to make do with them and all their imperfections for the foreseeable.

Australia’s 58 grid-scale battery storage systems in the NEM generated a combined AU$28.79 million in estimated gross energy and FCAS revenue.

Speaking to ESN Premium, Kashish Shah of Wärtsilä explains why Australia’s volatile market structure makes it uniquely suited for battery storage.

If BESS are to be given restricted grid access, they should be given a commensurate reduction in the BKZ fee, Marie-Sophie Braun, head of markets & regulatory affairs for developer Kyon Energy, said.

South Australia battery storage developer Lunio Energy has energised its first grid-scale BESS at Strathalbyn and started trading in the NEM.

BW ESS’ executive director Roberto Jimenez discusses the company’s recently-announced first Germany project, in Klostermansfeld, Saxony-Anhalt, which could be one of Europe’s largest when completed in 2028.

Australia’s 55 grid-scale BESS generated a combined AU$17.98 million in estimated gross energy and FCAS market revenue during June 2026.

The upcoming German capacity market must be designed in such a way that enables BESS to generate revenue, according to industry experts.
