Project Description:

  • When Line 1 of the TREA Leuna plant was erected it was originally one of the largest single-line power plants (195,000 t/a) in Germany. It was also unique in the country in that it was built according to the architect-engineer model, i.e., development was the responsibility of the owner, with Envi Con as the overall plant engineer and five individual lot suppliers
  • The plant was planned so that the boiler house and power building could be erected separately – spatially as well as chronologically
  • Live steam, at 40 bar and 400 °C, is conveyed via a pipe bridge to the power building
  • Water-steam circuit includes a single-casing condensing steam-extraction turbine with gearbox and synchronous Generator
  • Air-cooled condenser is located on the roof of the power building


Scope of Services:

  • General engineering and project management
  • Invitation to tender and specialist overall coordination of the five supplier lots
  • General layout planning and construction engineering
  • Site supervision and erection/assembly coordination
