Sky is about to take a major step closer towards its target of cutting carbon emissions by a quarter, by commissioning  a new combined cooling heat and power (CCHP) plant that could supply up to 40 per cent of energy to the broadcaster’s main studio complex, near Heathrow, London.

Steve Holford, head of engineering projects and energy at Sky, said he hopes to turn on the Turboden-made Organic Rankine Cycle turbine by the end of this month. This will provide both heat and electrical power to the company’s new sustainable studios.

At full capacity, the plant will take delivery of 32 tonnes of wood chips a day, sourced from local businesses in a 25-mile radius

After the higher grade heat has been extracted, lower-grade heat is recovered to create chilled water for cooling. The remaining heat is used for hot water, while some of the ash produced in the process can be sold to local horticulture businesses as a fertiliser.

The generator will also help Sky achieve targets to reduce its greenhouse gas emissions by 25 per cent, as well as improve energy efficiency by 20 per cent.

Sky decided to combine the CCHP plant with a bespoke 100kw wind turbine designed by Northern Power, which is expected to go live in March.
