German residential battery storage provider Sonnen and Swiss smartgrid developer Tiko have been given the green light to provide grid balancing using a “virtual battery” comprising home energy storage systems networked across Germany.”

Transmission system operator TenneT has pre-qualified the system— under which Tiko will deploy its real-time smartgrid network technology paired with Sonnen’s network of lithium iron phosphate batteries.

According to Sonnen, the company has “around 30,000 SonnenBatterie systems in Europe” for a total network capacity of up to 300MWh— enough to supply around 120,000 households with power for one hour.

Dutch electricity transmission system operator (TSO) TenneT is working with German battery storage firm Sonnen, Amsterdam-based energy company Vandebron and IBM to launch pilot projects integrating storage batteries into the power supply system via blockchain technology.

Blockchain, a platform developed by IBM, ensures the verifiability and transparency of the transactions of the small-scale batteries. It is expected to simplify how suppliers of locally distributed flexible energy provide services to support power grid operators in the future.
