The existing coal fired heating boilers were over 25 years old and at the end of their operational life. The Trust identified the need to move replace the plant with a gas fired solution which would remove the burden of coal handling on site and would improve environmental emissions and improve cost performance.
Under an agreement with Dalkia, a 1.4 MWe gas fired reciprocating CHP engine was installed alongside two new 6 te/hr steam boilers and a combination waste heat and fired boiler. The agreement also includes the subsequent operation and maintenance of the new plant and will provide secure and stable future energy supplies that provide a more cost effective and reliable energy solution for the hospital.
Benefits
Stable heating and electricity supplies to improve the patient care environment
Reduced environmental emissions as CHP units are typically twice as efficient at generating electricity than conventional generation -scheme reduces carbon dioxide emissions by approximately 4000 tonnes per year
PFI investment of £1.5million to cover the cost of construction
Cost and logistic savings compared to the previous energy plant
