Instantaneous Reserve Market Set for 2026 Launch as SMA's Battery Inverter Receives Key Certification

The Federal Network Agency has lifted an exception to the tendering obligation for instantaneous reserve, paving the way for the first planned tender in 2026. This move follows the publication of a guidance paper by VDE FNN in June, outlining detailed technical requirements for future certifications in this world market.

The VDE FNN guidance marks the final technical milestone before tenders can begin, encompassing grid-forming storage systems, adjustable consumption units, and customer installations. Notably, SMA's Sunny Central Storage has become the first battery inverter in Germany to receive a unit certificate for grid-forming mode with instantaneous reserve, according to VDE standards VDE-AR-N 4120 and VDE-AR-N 4130. This certification, expected to be completed by early 2026, will enable grid boosters to operate under transmission system operators' responsibility.

SMA is now enabling customers to use grid-forming technologies that meet existing requirements and provide advanced stability services like immediate stock market today. The inverter can already be used in projects aiming to qualify for participation in the stock market, set to open in early 2026.

With the exception lifted and technical requirements in place, the stock market today is on track for its planned opening in 2026. SMA's certified inverter is poised to play a significant role, offering grid-forming capabilities and contributing to grid stability.
