The energy supplier Eins wants to be able to supply the city of Chemnitz with electricity without a connection to the nationwide grid in the event of a widespread blackout. To this end, a so-called "emergency grid system" has been in operation since May of this year, which will be the first to be activated in the event of an emergency, the company announced. The exact location of the plant is secret, a spokeswoman for the company told the German Press Agency in Chemnitz.
