Salisbury District Hospital gains green rewards from combined heat and power
Salisbury District Hospital is using an innovative low carbon energy generation system to save money, reduce carbon dioxide emissions and ensure patient comfort.
Salisbury NHS Foundation Trust partnered with cogeneration specialists ENER-G to supply a combined heat and power (CHP) and district heating system.
This is generating the majority of the hospital’s heating and low temperature hot water requirements and a third of its electricity needs. In addition, the district heating scheme is feeding hot water and heating to its spinal treatment centre and day surgery unit, located in separate buildings.
The 850kWe ENER-G CHP system, which began operation 12 months ago, is releasing cash savings to the Trust of more than £240,000 per year. It is also reducing annual carbon dioxide emissions by 2,900 tonnes, which equates to the environmental benefit of removing 967 cars from the road or the carbon sequestered annually by 618 acres of pine forest.
“This innovative CHP project is key to the Trust’s carbon reduction strategy and is making a big contribution to achieving our green goals.”
Said George Atkinson, Head of Estates for Salisbury NHS Foundation Trust.
“The district heating system provides the perfect constant warm temperature required by people recovering from spinal injuries at our specialist treatment centre. Our CHP system satisfies normal heat requirements, with the back-up boilers only used if there is peak demand.”
Tony McDermott, Business Development Manager (Healthcare) for ENER-G Combined Power Ltd, said:
“Salisbury NHS Foundation Trust is demonstrating leadership in reducing carbon and proving that utilising energy efficient CHP makes financial sense too. By generating low cost energy, the CHP system will pay for itself within five years. The electricity produced is also exempt from Climate Change Levy carbon taxes, which increases the return on investment.”
Combined heat and power (CHP) is a well-proven technology, recognised worldwide as a cleaner and cheaper alternative to traditional centralised generation. It provides the simultaneous generation of electricity and useful heat and is around twice as efficient as conventional power generation where the generated heat is wasted and further losses of approximately 7% occur in transporting the electricity from remote power stations to end users.
ENER-G’s engineering team created a 520 metre network of pipes to deliver the heat and low temperature hot water from the CHP unit to the spinal treatment centre and neighbouring day surgery unit.
Salisbury NHS Foundation Trust provides a range of clinical care, which includes general acute and emergency services, to approximately 225,000 people in Wiltshire, Dorset and Hampshire.
Specialist services, such as burns, plastic surgery, cleft lip and palate, genetics and rehabilitation, extend to a much wider population of more than three million people.
The Duke of Cornwall Spinal Treatment Centre at Salisbury District Hospital covers most of southern England with a population of approximately 11 million people.
Trust staff provide outpatient clinics in other locations in Dorset and Hampshire. Specialist staff hold outreach clinics in hospitals within the Wessex area and, in total; the Trust employed 3,860 staff at 31 March 2012. This includes full and part-time staff
