Germany’s BESS offtake volumes up 7% in H1, says Pexapark

Total German BESS offtake volumes in the first half of 2026 exceeded full-year 2025 totals by 7%, Pexapark said in its latest market brief. The shift was driven in part by the first wave of co-located BESS structures entering the market.

Fixed-price agreement (FPA) volumes rose from 254 MW across all of 2025 to 642 MW in the first half of 2026, an increase of 153%, said Pexapark. The Switzerland-based firm said the shift reflects the growing role of debt financing in the BESS sector, with lenders requesting a higher share of fixed revenues for battery assets.

Tolls are the dominant structure in the German market, Pexapark said, while day-ahead swaps are an emerging alternative. The company noted that three such deals have been announced to date, two of them in June.

Among deals listed in Pexapark’s tracker was a co-located solar deal in Germany involving Enertrag and e2m on June 30, and a co-located solar deal in Great Britain involving OnPath Energy and Smartest Energy on June 29.

The shift toward fixed-revenue structures echoes recent comments from Akaysha Energy, which said German lenders require 60% to 80% contracted revenue before committing project debt to BESS projects.

Pexapark’s “Renewables Market Outlook 2026” report flagged the emerging trend when it was published earlier this year. It said that Europe contracted nearly 24 GWh of BESS capacity under flexibility purchase agreements and optimization agreements in 2025 – triple the volume recorded in 2024.
