Eco Stor starts building 238MWh BESS in Germany

EPC and developer Eco Stor has initiated construction on a 238MWh battery energy storage system (BESS) in Germany, which is being touted as one of the largest in the country.

A groundbreaking ceremony for the 103MW/238MWh BESS project in Bollingstedt, Schleswig-Holstein, was held on 19 April, attended by company executives and local stakeholders.

The project, spanning 1.2 hectares on the Gammelund industrial park, will consist of two of Eco Stor’s ‘Eco Stor ES-50C’ BESS array configuration.

Each array will include a 110kV substation, 16 inverter and transformer containers, and 32 containers equipped with lithium-ion batteries.

Eco Stor is currently developing several large-scale BESS projects across Germany, including 300MW/600MWh systems as part of its ‘Eco Power’ series.

The company aims to commence the construction of the first system by late 2024.

While Eco Stor covers various aspects of a project’s lifecycle, such as early-stage development and BESS technology, it collaborates with external companies for route-to-market and optimization activities once operational.

Other notable projects claiming the title of the largest in Germany include a 100MW/200MWh system that commenced construction in late 2023, and a 275MWh system for which developer Kyon Energy received approval around the same time.

Germany’s significant push for renewable energy, particularly its ambitious solar PV deployment target, is driving the growth of the energy storage market.

BloombergNEF has forecasted that by 2030, Germany will become the world’s third-largest energy storage market, following China and the US, with cumulative installs reaching 62GW/109GWh.

Georg Gallmetzer, managing director at Eco Stor Germany, commented: “Electricity prices are becoming increasingly sensitive to the weather.

With increasing production of wind and solar power, more and larger storage systems and their balancing effect are needed.

They ensure more stability in the network, affordable prices and a clean mix of renewable energy.”
