Slough, London
Main Contractor
Project Length

The SSE Slough Power Station project comprises decommissioning and demolition of over 75% of plant and structures on the site, with the remaining facilities to remain live and operational during the course of the contract.

Due to the complexity of ongoing decommissioning and isolation works being carried out by other contractors, the site is being released to Keltbray in stages, with Keltbray’s appointment extended by SSE to cover the critical role of coordinating all on-site activities.

Slough Power Station was originally built in the 1920s as coal fired, but was modified over the years to the use of multi-fuel (mainly waste and wood chip) for the generation of both power and heat supplied direct to the surrounding Slough Trading Estate – the largest in Europe.

Because of its location surrounded by high value businesses, environmental issues including noise, dust and vibration are of the highest priority, with appropriate demolition methodologies and control measures developed to ensure compliance with stakeholder requirements. These include:

  • Breaking down the concrete chimney working from an elevated moveable platform.
  • Heavy crane lifting to remove the Boilers, Cyclones and the original Coal Bunkers.
  • Dismantling the main Boilerhouse structure using a tower crane located within the plan footprint of the building and built off the existing heavy pile caps.
  • Hydraulic bursting of heavy foundations to make way for the site’s redevelopment
