Capacity:50MWe or 202T/h

5 x 50 MWe steam generators

Over a period of three years, Aalborg CSP developed and supplied five steam generation systems for concentrated solar power parabolic trough plants located within Europe’s largest solar complex in Spain. Each plant produces 50MW, enough electricity to satisfy the power needs of 25,700 households. 

Each of the five CSP plants consists of 53 km parabolic troughs. The parabolic trough solar collectors collect and reflect the sun's rays onto a receiver pipe wherein thermal oil is heated. The energy is then transfered to the steam generator. Each plant produces 50MW, which is enough electricity to cover the power needs of 25,700 households.
Aalborg CSP's scope included design, engineering, procurement, complete installation and commissioning of the boiler equipment. The five steam generators are from the first and second configuration of Aalborg CSP's steam generation technology.

Scope of  supply: 

  • Evaporator units (incl. steam drums)
  • Economizers, superheaters, reheater
  • Piping gallery (valves, drain, headers etc.) 
  • Mechanical and electrical installation
  • Design and P&I diagrams
  • 3D model
  • Steel structure
  • Strength and flex calculations
  • Documentation
  • Supervision of installation and commissioning
  • Legalization of the plant
