FINANCE: Frimley Park Hospital says its combined cooling, heat and power plant (CHP) is saving it £367,000 a year.

The CHP plant – also called tri-generation – was funded by a £2.7m grant from the Department of Health’s energy and sustainability fund and a £450,000 investment from the FT itself.

The plant has been in place since October 2008 and is now saving more than a third of a million pounds a year and resulting in a carbon saving of 1,260 tonnes of carbon dioxide, according to the trust, which is also able to sell back surplus electricity that it generates to the National Grid.

Trust general manager of facilities Colin Mapperley said: “The project has been a big success both in terms of the money it has saved and the lower impact on the environment.

“We have also seen energy prices go far higher than anyone anticipated in recent years, but the success of the project has meant that we have been able to cope well with these extra unit costs.”

The tri-generation plant incorporates two absorption chillers and four giant blast coolers. It provides a “heat sink” for the CHP to run air conditioning systems in warm weather and return heat to the main heating system when the weather is colder.
