Planning and construction of an emergency power system with black start capability

eins energie in sachsen GmbH & Co. KG (eins) operates a lignite-fired power plant in the city of Chemnitz for electricity and heat generation. As part of the planned coal phase-out, the Chemnitz Heat Supply Project Team (WV) is implementing the construction of new gas-based motor heating power plants (MHKW) at the North (MHKWN) and Altchemnitz (MHKWA) sites.

In order to be able to act flexibly and safely in emergency situations, the new MHKWs will be equipped with the ability to start black. The planned concept envisages carrying out a grid reconstruction with the Motorheizkraftwerk Nord (MHKWN) in the event of black. The personal requirements required for the black start are to be provided by a stationary emergency power supply system (diesel generator). This unit is also intended to supply two other consumers in the event of black.
