Inspenet, December 3, 2023.
An international consortium composed of Sener, GE Vernova and Bonatti will be responsible for the engineering, supply and construction of the two new thermoelectric power plants of the company EnBW in Heilbronn and Altbach/Deizisau, located near Stuttgart, the capital and largest city of Baden-Württemberg, Germany.
The contracts cover both the provision and construction of the facilities, as well as software solutions, maintenance and services over ten years, as announced in a statement by the Basque company.
The transition to natural gas
These projects aim to replace existing coal plants with more efficient natural gas facilities. Additionally, these new plants are planned to enable future combustion of fuel mixtures, including up to 100% hydrogen by volume, by the 2030s. The gas business division of GE Vernova, leader of the consortium, has confirmed the obtaining of two orders from EnBW to supply combined cycle power generation equipment fueled by Class H natural gas for these facilities.
The highly efficient Heilbronn and Altbach/Deizisau thermal power plants are projected to supply a total capacity of almost 1,340 MW to the national grid, equivalent to the amount needed to power approximately 2.4 million German homes. In addition, they will provide steam for district heating for citizens, businesses and industries in Heilbronn and the Stuttgart metropolitan area.
Each of these 680 MW power plants will replace pre-existing coal units in Heilbronn and Altbach/Deizisau, and these new facilities are anticipated to come online by the end of 2026. The transition from a coal plant to its gas equivalent can result in a 60% reduction in carbon emissions , while reducing emissions of other pollutants such as mercury, NOx, SOx and particles, thanks to the use of turbines more advanced HA gas.
