UK hospital claims CHP saving of US$575,000 a year

A Surrey hospital claims to be making considerable cost saving through installing a new combined heat and power (CHP) plant.

The plant, which has four blast coolers and two absorption chillers, has resulted in a carbon saving of 1260 tonnes each year, the hospital claims, with surplus electricity sold to the National Grid.

The NHS trust puts total savings at à‚£367,000 ($575,000) a year.

Frimley Park Hospital received a grant of à‚£2.7 million for the CHP plant, which began operations in October 2008.

A new surgery unit and increased theatre capacity had led to a higher demand for energy, said the NHS trust. It provides a heat sink to run air conditioning systems in the summer and warms the main heating system in the winter.

The trust has a carbon management plan which sets out how it will reduce its carbon footprint by 15% by 2015. The plan includes the replacement of 9000 lights for energy-efficient lighting and upgrading the heating system in ward areas, saving about 90 tonnes of carbon dioxide per year.
