Bankable BESS contract in Germany expands European footprint; supply starts March 2026

The agreement commits e-STORAGE to deliver a 20.7 MW / 56 MWh integrated BESS and a 20-year LTSA in Lower Saxony, Germany. The deal ties supply, commissioning, and long-term services to a project developed by Kyon Energy with EPC-M responsibilities, creating a single accountable delivery chain.

Dependencies and risks include timely shipments starting March 2026, successful on-site commissioning later that year, and long-term performance under the LTSA. Contractual execution, supply chain timing, and commissioning outcomes will determine near-term revenue recognition and future service income.

Watch for three concrete items: shipment commencement in March 2026, commissioning status updates later in 2026, and any LTSA performance KPIs or warranty claims during the first year of operation. Expect materially visible milestones across the next 12–18 months.
