The ten-year deal includes the installation of two CHP units, which has already been completed, as well as an additional contract signed this week for lifetime monitoring and maintenance.
The 4 MW CHP units are expected to help the university in reducing its carbon emissions by approximately 35 per cent by 2020 against a 1990 baseline – an expected annual emissions reduction of 4000 tonnes.
The CHP units replace the originals installed in 1999 and join a third existing unit. Together they are designed to generate roughly 30 GWh of electricity per year, and to supply power and heat to the campus via a district heating and cooling network.
New, more energy-efficient boilers, pumps and thermal stores have also been installed to capture surplus heat from the CHPs and use it throughout the day if required, Veolia said, adding that the storage facilities can hold 200,000 tonnes of water in order store the excess heat.
The installation of the CHP units represented the final phase of a three-year project to modify the university’s energy facilities.
University representative Richard Bettle said the new systems “will allow us to generate over 80 per cent of electricity on-site, reducing costs and carbon dioxide emissions”.
