Solar PV manufacturer Trina Solar will provide the lithium iron phosphate (LFP) battery energy storage system (BESS) units from its storage arm Trina Storage, while H&MV Engineering will construct the project. Trina’s BESS product Elementa uses in-house manufactured battery cells.

Strübbel is in the onshore wind area between Hamburg and St. Peter-Ording, which Aquila said creates ideal conditions for balancing out intermittent renewable energy generation.

Schleswig-Holstein is in northern Germany, where most renewable energy generation is, while most demand centres are in the south. That imbalance creates a need for energy storage, to balance regional differences in supply and demand but also for storage-as-transmission projects, covered most recently here.

System integrator Fluence’s senior manager for policy and market development said on LinkedIn this week that revenues for BESS in Germany have soared this summer, to around €308,000 per MW on an annualised basis, six times higher than in the UK. It’s been a volatile time however, with BESS owner-operator Gore Street revealing that revenues there for the year to March 2024 had fallen by 47% to around €95,000 per MW.

Andrew Wojtek, CEO of Aquila Clean Energy EMEA, said: “Battery storage systems contribute significantly to system stability in an electricity mix with a high share of renewable energies and are therefore a crucial factor for the achievement of our objective of making affordable, clean electricity available to market participants.”

Aquila Clean Energy, part of Aquila Capital, is a renewable and energy storage developer active across Europe and Australia. In energy storage, it was an early mover in Belgium, and is also actively developing projects in Italy, Poland, Australia and elsewhere.
