Millcroft provided access scaffolding services worth over £3.4 million on this major energy construction project which was completed in May 2010. Alstom was the contractor on the new 1,275 MW power plant located at the Isle of Grain in Kent, creating the largest combined Heat and Power plant in the UK. The plant, consisting of three natural gas-fired units, is capable of generating enough electricity to supply around one million homes. The waste heat from the power station is used to heat a closed circuit water cooling system which in turn is used to convert liquefied natural gas (LNG) at -160 degrees centigrade back to gas for entry into the UK gas distribution system. This process takes the efficiency of the plant to over 70% and saves over 300,000 tonnes of CO2 in emissions per year. Access scaffolding on the project ranged from basic access towers during construction of the main plant to a rolling temporary roof over a 400 ton transformer whilst a technical investigation was carried out. A team of up to 50 scaffolders worked on the project over a period of two years.
