en.Wedoany.com Reported - July 13, 2026,German bank UmweltBank has provided financing for an 11 MW/22 MWh standalone battery energy storage system (BESS) in Halle (Saale), relying entirely on commercial market revenues rather than minimum price or tolling agreements.
The project was developed in cooperation with CCE. UmweltBank stated that the ten-year financing structure is designed to maximize operational flexibility and revenue opportunities for investors.
Holger Donhauser, Head of Renewable Energy Financing at UmweltBank, noted that it took only nine weeks from the client's investment decision to the first loan disbursement, reflecting the coordination among all parties involved.
UmweltBank entered the battery storage financing market earlier this year and has already financed several standalone and co-located battery projects.
Goran Basic, Member of the Management Board at UmweltBank, pointed out that the main challenges in battery storage financing lie in assessing long-term technical performance and future revenues. He stated that banks typically take a more conservative view of commercial market risks and battery degradation compared to developers and investors.
The bank plans to finance more storage projects, adding that co-located solar-plus-storage plants are becoming an industry standard due to their strong economics. Such projects are often supported by hybrid power purchase agreements (PPAs), an area where the bank has already gained experience in solar and wind financing.
UmweltBank also announced plans to finance the first wind farms with integrated battery storage next year and is already developing suitable PPA structures.
