Overview
- Official data show that between January and September 2026 Germany added about 8.2 GWh of new battery capacity, a 91 percent increase over the prior year.
- Large‑scale 'Großspeicher' accounted for roughly half of the new capacity, with their additions more than quadrupling to about 3.8 GWh and shifting the market toward utility‑scale projects.
- The solar industry group BSW‑Solar has published a 15‑point reform package seeking easier grid connections, auctions for grid‑supportive substation storage, changes to redispatch rules, net‑fee protections, and stronger storage R&D support to sustain the rollout.
- Industry cites Fraunhofer IEE modelling that estimates an extra 80 GWh of storage could have lowered costs to taxpayers and the federal budget by nearly €4 billion in 2025, framing storage as a measurable system saver.
- Commercial and local activity is expanding: vendors showcased higher‑power modular home storages at IFA 2026 (availability for some models in Germany is still being reported as pending), while regional projects such as a planned ~12.2 MWh/4.5 MW Bad Wörishofen battery using new automotive cells aim to smooth PV peaks and give tangible benefits to about 1,200 households per day; current rules that cap household feed‑in at 800 W are driving more households to add storage to capture midday solar output.
