UNIVERSITY OF WESTERN ENGLAND, BRISTOL, INSTALLS NEW PV SYSTEM
THE NHS COULD SAVE £26.4M ANNUALLY USING CHP TECH
The installation of a 450kWp roof array at its Frenchay Campus means that The UWE Bristol will quadruple its onsite solar generating capacity, report the university authorities. Claimed to be ‘the largest single roof-mounted solar PV array at any UK university’,
this latest investment - more than £650,000 - in green energy involves 1,700 modules designed to generate 400 MW of electricity each year. The innovation will provide annual savings of £55,000 a year as well as reducing carbon emissions by around 200 tonnes annually. The modules will cover the roof of a 10,000 square metre building that houses the University Enterprise Zone and the Bristol Robotics Laboratory, with the aim of generating up to half of the energy consumed annually by the two energy-intensive departments. The university is also developing a combined heat and power system on site that will
burn gas to generate electricity for use on the same campus, with buildings such as the Students' Union and student accommodation making use of the heat via underground pipes. Jointly, the CHP facility and district heating project are xpected to save around 1,100 tonnes of CO2 each year, according to UWE Bristol, which said it recognised the importance of on-site generation in cutting carbon, increasing energy security and enhancing local renewables capacity. The University of the West of England (UWE Bristol) will be opting for a 100% green electricity tariff with EDF from October 2016 under a new framework from The Energy Consortia (TEC). UWE Bristol spends circa £3m/year on electricity and for an uplift of less than 0.3%
has chosen to secure 100% of its electricity supply from renewable sources, verified by the REGO (Renewable Energy Guarantees of Origin) certificates. Energy Manager for UWE Bristol, Fabia Jeddere-Fisher, told UKPN: “The new TEC Framework with EDF has now made it possible for us to purchase electricity guaranteed from renewable sources that is affordable and doesn't put a strain on our budget. This was a no-brainer for us. Our students and staff still get an excellent service overall, plus we know the electricity we consume on site has come from renewable sources either on-site, including our new 450kWp PV array, or from our new renewable tariff. “In addition, this switch will move us into the top quartile of universities making this commitment to purchasing renewable energy. We are currently somewhere in the middle of the Association of University Directors of Estates (AUDE) Green Scorecard for this measure, but this commitment will see us leap up the ratings.” William Liew, Finance Director for UWE Bristol, comments: “This is another big step
in the right direction and shows how we are striving to strategically integrate sustainability across all activities. Together with the decision to invest in the largest PV Array in the HE Sector, this move sends out a positive message to our staff, students and wider community that we are committed to reducing our impact on the environment Buying green electricity integrates with the raft of other sustainable initiatives, from how we plan our building projects to how we develop transport options.” Fabia Jeddere-Fisher concludes: “We believe that UWE Bristol is setting a great example. The more large businesses and institutions that opt to buy into this way of consuming energy, the more we can collectively encourage the industry to deliver more renewable energy options. If there is demand, the pressure to supply will be established. Using the TEC framework, there are a number of other Universities also making this move, and together we can really stimulate this market.”
AUTUMN 2016 UK POWER NEWS
A new report - Securing Healthy Returns - from NHS England’s Sustainable Development Unit - sug- gests that combined heat and power systems could save the UK’s National Health Service (NHS) around £26.4 million annually in energy savings. The reports indicates that out of 18 sustainability measures reviewed, installing CHP systems offered the highest potential yearly cost savings, as well as the potential to cut carbon dioxide emissions by 3750 tonnes. In total, the report found that overall energy efficiency measures could save the NHS £400 million and reduce carbon emissions by 1 million tonnes per year by 2020. The case studies cited in the report included Rampton Hospital in Nottinghamshire, which replaced a coal-fired heating plant with a CHP system and a wood chip boiler, reducing energy costs by 44%,
saving around £790,000 per year and cutting 8614 tonnes of CO2. York Teaching Hospital,
which installed a large CHP system, saved £680,000 per year in energy costs and cut 2997 tonnes of CO2. The NHS has been tasked
by the government with find- ing £22 billion in efficiency savings within five years. Using a CHP or cogeneration plant in a hospital is an ideal way of achieving improved energy efficiency and reduced carbon emissions. A CHP plant facilitates the
high efficiency use of natural gas by recovering not only electricity but also heat. If the hospital has need for cooling, hospital trigeneration tech can produce cold water for refrig- eration or air conditioning.
Kent CHP plant is supported by the UK’s Contract for Difference (CfD) mechanism
A combined heat and power plant in Kent is the first large- scale energy from waste facility supported by the UK’s Contract for Difference (CfD) mechanism. The Green Investment Bank plc (GIB) has committed £80m to the construction of the energy from waste facility near Sittingbourne in Kent. Once complete, the 43 MW plant will supply renewable electricity
to the grid and renewable heat to DS Smith’s Kemsley Paper Mill, which produces sustainable packaging for the retail industry. The plant is expected to help decarbonise the production process
by replacing part of the mill’s gas-fired steam supply and support the UK government’s increasing efforts to cut carbon emissions from the manufacturing sector. The project developer, Wheelabrator Technologies Inc (WTI),
has secured more than £300m of debt from a lending club that includes GIB alongside Barclays, Bank of Tokyo-Mitsubishi UFJ (BTMU), Natixis and Investec. It is expected to generate up to 154 GWh of renewable electricity annually once fully operational – equivalent to the power consumed by 37,500 homes – and 180 GWH of renewable heat. The facility is also expected to help reduce greenhouse gas emissions by over 163,000 tonnes per year.
