Government departments use combined heat and power
GSH Group, ENER-G and Telereal Trillium teamed up to install a combined heat and power (CHP) system at Quarry House in Leeds. The occupiers, the Department for Work and Pensions (DWP) and Department of Health are set to save £90,000 per year and reduce annual carbon emissions by over 430 tonnes with the high-tech energy-saving system.
The 500kW ENER-G CHP system, which produces 500kW of electricity and 568kW of heat, is set to transform the way DWP and the Department of Health use heating and reduce carbon emissions by converting a single fuel into both electricity and heat in a single process at the point of use. It represents the first installation of its kind within DWP’s portfolio and is designed to reduce energy consumption by up to 20 per cent at Quarry House.
Richard Fountain, head of sustainability and climate change at Department for Work and Pensions commented: "We are very proud of this installation and it is a highly rated example of the close working relationships within the government and with the service providers. We estimate net financial savings of around £90,000 a year and half a percent contribution to DWP’s overall carbon reduction target."
Simon Phillips, energy environment director for Telereal Trillium said: "Of all DWP’s properties, Quarry House uses three per cent of the total energy across the estate. In terms of electricity consumption, this was more than £1,000 a day, so the new system will deliver real savings immediately on the DWP’s energy costs."
Tommy Fisher, technical project manager for GSH said: "We have worked closely with our partners Telereal Trillium and ENER-G to provide an innovative energy solution at Quarry House that will achieve considerable value for the two Government departments. It was a challenging project involving heavy plant equipment and technical challenges, so the successful installation is testament to the efforts and expertise of everyone involved."
Mark Pollard, senior project engineer at ENER-G said: "We all feel that the installation has been a great success. We finished within the budget and time frame, which given some of the restrictions at the start, was a fantastic achievement."
CHP is the simultaneous production of electricity and heat that is carbon reducing and offers an alternative to traditional fossil fuel power sources. An engine (normally gas fuelled) is linked to an alternator to produce the electricity; whist heat produced by the engine is collected from oil, jacket water and exhaust gases by heat exchangers, and used to heat the building. The process increases fuel efficiency and minimises energy loss.
