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.
In 2018 and 2021, they successfully completed the investment in the new gas units PB6 and PB7, with a nominal power of 53 megawatts and 56 megawatts. With this, Termoelektrarna Brestanica realized the first phase of the development project for the replacement of gas blocks PB1-3. The project was completed in accordance with the financial and time schedule.
The TEB generated 52.3 GWh of electricity in 2021.
