Global resource management group, Veolia, through its subsidiary Veolia CHP UK Limited, is helping the University of East Anglia (UEA) to reduce carbon emissions through a new 10-year combined heat and power contract. This will provide low carbon electricity and heat to the University of East Anglia and see two of the latest generation of Veolia combined heat and power (CHP) units installed to deliver secure energy supplies. The 4MWe CHP installation will help the university reduce campus carbon emissions by 35% by 2020, against a 1990 baseline and support their ‘Sustainable Ways’ vision where the efficient use of resources and self-generated energy support low carbon goals.
Designed to produce around 30GWh of electricity a year and maximise heat efficiency, the CHP will cut annual carbon emissions by a further 4,000 tonnes. The system is based around two of the latest generation of Veolia 2MWe units which will deliver low carbon heat and electricity to the 320-acre campus through the district heating and cooling network and electrical infrastructure. This maintains the energy supply for the buildings that support the academic and research activities for over 18,800 students and staff.
This is the final part of a three-year project to update energy facilities at UEA. Along with new, more energy efficient boilers and pumps, Thermal Stores have been installed to capture excess heat from the CHPs and use it later in the day when needed. These tanks hold 200,000 litres of water, an efficient way to store the excess heat generated by the CHP engines.
The CHP installation phase of the project was completed in October 2017 and will be supported by a 10-year contract using Veolia’s CHP helpdesk to provide lifetime monitoring. Optimised maintenance will be provided by the company’s nationwide field service teams.
Commenting on the new contract, Gavin Graveson, Veolia’s chief operating officer, public and commercial, Veolia UK says, “Our combined heat and power units are already supporting the sustainable goals of over 60 campuses in the UK and reducing their carbon emissions by over 40,000 tonnes each year. By deploying this new generation of units that include the latest industry innovations, we will be able to help the campus to increase energy efficiency.”
Richard Bettle from UEA adds, “These latest CHP engines replaced the original engines installed in 1999 and, along with a third existing CHP engine, will allow us to generate over 80% of electricity on site, reducing costs and CO2 emissions.”
Veolia currently have around 30MWe of CHP capacity that provides energy on over 60 university campuses, supporting their education and research facilities, and housing more than 200,000 students.
