Backup energy supply in the event of large power plant outages

For a number of years now, Brestanica Thermal Power Plant (TEB) has played a special role in the national electric power grid and the GEN Group. With its specific technology, gas turbine units with a combined capacity of 297 MW, and favourable location, it provides critical ancillary services inside the national electric power grid (tertiary frequency control, capability to perform secondary frequency control with the larger gas turbine unit in operation, operating black-start generators, and delivering an independent and direct power supply to NEK).

TEB's electricity output is largely dependent on how often the power plant needs to be started up to serve as a backup power source in the event any of the large power generation units in the national electric power grid comes offline. With an impeccable start-up track record, TEB in 2015 fulfilled its role in helping ensure stability of Slovenia's electric power grid.
