MaxSolar signs deal for 100 MWh grid-support BESS in Germany

Entrix has signed an agreement to optimize and trade output from Maxsolar’s 20 MW/100 MWh grid-support battery storage system near Ansbach, as the German developer also commissions a separate 76 MW subsidy-free solar plant in Bavaria.

German renewable energy developer MaxSolar has selected Entrix to optimize and commercialize a 20 MW/100 MWh battery energy storage system (BESS) designed to provide grid-support services in southern Germany.

The five-hour battery project in Winterschneidbach, near Ansbach, Bavaria, is being developed for distribution network operator N-Ergie and is intended to help stabilize the local grid. MaxSolar and Entrix said the system will operate on a fully merchant basis, using AI-supported trading strategies aimed at balancing commercial returns with grid requirements.

MaxSolar said the Winterschneidbach project is the second grid-support battery storage system it has developed on behalf of a German distribution network operator. The company is also building a similar project in the Bayernwerk network area.

Separately, MaxSolar has commissioned a 76 MW solar park in Amerdingen in Bavaria. The subsidy-free project operates under a long-term power purchase agreement covering about 70% of its output, with the remaining electricity to be sold through direct market trading.

The solar facility was developed on land owned by Camilla Princess zu Sayn-Wittgenstein-Berleburg and comprises nearly 127,000 solar modules installed across 51 hectares.

Policy

Voltwise: Extend German grid fee exemption for large batteries to 2034 Germany's Federal Network Agency is consulting on a proposed overhaul of its grid fees to introduce a General Grid-Fee System (AgNES). Battery energy storage systems (BESS) are currently exempt from the charges and Voltwise's head of German operations, Thorsten Klöpper, is suggesting a three-stage system which takes account of battery-related grid benefits.

Grid-forming tech on center stage as search for system resilience steps up Maintaining grid stability becomes more challenging as the share of intermittent renewables grows in the electricity generation mix, but system resilience is essential to continued solar deployment. Grid-forming inverters offer a solution, and their capabilities are increasingly being tested and relied upon in key energy markets globally.

Opinion & Analysis

German battery energy storage: a key technology for grid integration? While Germany's new coalition government has made the right noises about energy storage in its written agreement, the lack of concrete reform and legal certainty in the terms used is not enough for investors to bank on.

“Grid-forming technology is no longer experimental – it’s here and working” In grids increasingly dominated by renewables, grid-forming technology is emerging as critical tool for maintaining stability and ensuring reliable power system operation. In this interview with ESS News, Rui Sun, Sungrow’s Deputy General Manager-Grid Technology Center, explains how grid-forming works, why it matters, and where the technology is already proving its value. He elaborates on technical challenges, regulatory gaps, and why grid-forming could soon become the new industry standard.
