In 2005 with their heating boilers are at the end of their operational life and not able to meet the future energy demands of the hospital, the Trust looked for ways of replacing them. As part of the ongoing improvements to the hospital’s services and in line with the mandatory NHS targets and the Climate Change Programme, the Trust looked to upgrade its energy facilities and improve continuity of supply, reduce carbon emissions and achieve cost reductions. 

To meet the Hospital’s heating, cooling and electricity needs Dalkia designed, built, financed, a new energy centre that includes a 1.4MWe gas fired CHP engine and waste heat boiler, two additional boilers, a 330kW absorption chiller, heat exchangers and high and low voltage switchboard.


  • CO2 Emissions cut by 4000 tonnes per year
  • £2.9million funding for the scheme - this preserves the Trusts capital resources
  • Cost savings of £245,000 per year
  • Expert support, maintenance and risk transfer for 15 years
  • Export electricity revenues maximised
