The demanding targets for reducing their carbon footprint by 25% and water use by 20% by 2020 incentivised the installation of a combined heat and power plant to help GSK to reduce carbon emissions dramatically. At the same time it helped the company to make financial savings through operating a more efficient power generation system.

ENER-G was contracted to deliver 20MWe of cogeneration to 8 sites across the UK and Europe which equates to a total contract value of £15M. The package included the installation of 6 x 2MWe cogeneration units, 5 x 1150kWe units, 1 x 1600kWe unit and 2 x 1MWe units to provide electricity, hot water and steam supply to the production facility. 

Each year, across the sites, GSK will achieve a 25% reduction on their energy bills and save over 62,915 tonnes of carbon, equivalent to the environmental benefit of 20,972 cars off the road each year, reducing the site’s CO2 output by 15%.
