Germany: NGEN starts building 100MWh BESS, Harmony Energy secures 3GWh pipeline financing

NGEN and Harmony Energy have made strides in deploying large-scale BESS projects in Germany, launching construction and securing pipeline financing respectively.

NGEN

Owner-operator NGEN has broken ground on a 50MW/100MWh battery energy storage system (BESS) project in Wilhelmshaven, Germany, being deployed in partnership with power firm Uniper.

Commissioning is scheduled for Q4 2026. It is on the former site of a Uniper thermal power plant, and the BESS is part of a redevelopment of the entire site as a renewable energy hub, the Energy Transformation Hub Nordwest (ETHNw).

NGEN is based in Slovenia but has deployed or is deploying BESS in multiple European countries, including its home market, Austria, Croatia, Poland, Portugal and now Germany. We spoke to founder and CEO Roman Bernard just before it expanded outside its initial core markets in 2023. It has typically used Tesla for its projects.

Held alongside The Battery Show Europe, Energy Storage Summit provides a focused platform to understand the policies, revenue models and deployment conditions shaping Germany’s utility-scale storage boom. With contributions from TSOs, banks, developers and optimisers, the Summit explores regulation, merchant strategies, financing, grid tariffs and project delivery in a market forecast to integrate 24GW of storage by 2037.

Launching September 2026 in Berlin, Energy Storage Summit Germany is a new standalone event dedicated to Germany’s energy storage market. Bringing together investors, developers, policymakers, TSOs, manufacturers and optimisation specialists, the Summit explores the regulatory shifts, revenue models, financing strategies and technology innovations shaping large-scale deployment. With Germany targeting 80% renewables by 2030, it offers a focused platform to connect with the decision-makers driving the Energiewende and the future of utility-scale storage.

Battery Asset Management Summit Europe is the annual meeting for owners, operators, investors, and optimisation specialists working with operational BESS assets across the continent. The Summit focuses on how to maximise performance and revenue, manage degradation, integrate advanced optimisation software, navigate evolving market and regulatory frameworks, and plan for repowering or end-of-life strategies. With insights from Europe’s most active storage markets, it equips attendees with practical guidance to run resilient, profitable battery portfolios as the sector scales.
