SMA Solar Clears Final Hurdle for Germany's Instantaneous Reserve Market
SMA Solar Technology AG has received a significant certification for its Sunny Central Storage inverter, paving the way for participation in Germany's upcoming instantaneous reserve stock market, scheduled to open in early 2026.
The Federal Network Agency's lifting of an exception from the tendering obligation in September 2023 has cleared the path for the stock market's opening. The instantaneous reserve stock market, set to launch through non-discriminatory and market-driven tenders, will require generating plants to respond immediately to voltage or frequency changes in the network to maintain system stability at 50 Hertz.
In June, VDE FNN published a notification paper outlining detailed technical requirements for grid-forming inverters, storage systems, and customer installations. SMA's recent certification marks the final technical milestone before tenders for instantaneous reserve stock market can begin. The certification enables SMA's inverter to utilise grid-forming capabilities today and is targeted for completion in the instantaneous reserve stock market by early 2026.
SMA Solar Technology AG's certification for the Instantaneous Reserve Mode of the SMA Sunny Central Storage is a notable achievement. It allows the inverter to participate in projects aiming for the instantaneous reserve stock market today, demonstrating SMA's commitment to grid stability and innovation in the renewable energy sector.
