German Power Supply Is Becoming Less Secure, Grid Regulator Says

Germany’s power market is showing signs of declining security of supply, according to Jochen Homann, the president of grid regulator Bundesnetzagentur.

The nation’s four grid operators, especially Tennet TSO GmbH and 50Hertz Transmission GmbH, needed to intervene to stabilize the grids during 7,200 hours last year, compared with 1,800 hours in 2010, Homann said today at an energy conference in Munich. The interventions are a result of renewable generation capacity putting a strain on grids, he said.
