“Safety grid for power”

Power grid operator Tennet and household power storage provider Sonnen plan to use a network of small-scale batteries to help reduce costs caused by grid bottlenecks between Germany’s windy North and the power-hungry South, reports Michael Bauchmüller in Süddeutsche Zeitung. “We want to integrate renewable power in the best possible way,” Tennet board chair Urban Keussen told the newspaper. “We can manage that not only with copper, but also with intelligence.” Sonnen managing director Philipp Schröder said that in a first stage, 6,000 batteries would be used to optimise the power grid. Households making their batteries available for the project, which will use blockchain encryption technology, will receive free power, according to the article. Keussen told newspaper Die Welt the use of blockchain was “the first step into a new energy world.”
