Damage to unit 7 of the Heilbronn power plant
Heilbronn. Last week, a major damage event occurred at unit 7 of the coal-fired power plant at the Heilbronn site. For unknown reasons, parts of flue gas ducts in the boiler house have loosened and sunk downward. No one was injured. The unit was not in operation at the time of the collapse. The collapse of the duct did not cause any emissions.
It is expected that the block will be out of service for a longer period due to repairs. The damage is currently being assessed at the power plant. More detailed information on the cause and effect of the collapse can only be provided after a complete assessment of the damage.
Unit 7 has an electrical output of 778 megawatts. Based on the principle of cogeneration, unit 7 produces climate-friendly district heating in addition to electricity. District heat generation at the site is ensured by so-called auxiliary steam generators despite the outage of unit 7. Only two industrial customers cannot be supplied temporarily from the site. These customers have been informed and have switched to self-supply.
Grid reserve units 5 and 6 at the Heilbronn site are not affected. They have been in the operational control of the transmission grid operator Transnet BW since 2015 and are called upon if necessary to support system security in the event of grid instabilities.
With over 26,000 employees, EnBW is one of the largest energy companies in Germany and Europe. It supplies around 5.5 million customers with electricity, gas, water as well as services and products in the areas of infrastructure and energy. The expansion of renewable energies is a cornerstone of the growth strategy and a focus of investment. EnBW will invest around 4 billion euros in the further expansion of wind and solar energy by 2025. By the end of 2025, more than half of the generation portfolio is set to consist of renewable energies. This is already having a noticeable effect on reducing CO₂ emissions, which EnBW aims to halve by 2030. EnBW is aiming for climate neutrality by 2035.
