Cutting NHS Energy Bills
UK firm Edina is helping slash British health sector energy expenses.
A
s hospitals grapple with high energy costs and carbon emission targets, many hospital trusts are looking for new ways to tackle the problem. Edina’s involvement with the provision of CHP (COMBINED HEAT AND POWER) to the Health Sector began nearly 30 years ago with the project to install and maintain the energy centre at St. James’s Hospital Dublin, the largest in the city. The Edina group of companies has specialised in onsite power generation for over 25 years. With over 140 qualified staff operating at 5 locations in 2 countries “true” national coverage for all service and maintenance requirements is provided. The spectrum of fuel sources are catered for in the product range, diesel, natural gas, biogas and synthetic gases. Edina offers design, supply, hire and full turnkey solutions and constructs the container and all related operational products at its manufacturing premises in Lisburn, Northern Ireland. Edina Group is the official
distributor in the UK and Ireland of the MWM engine range. MWM is the oldest manufacturer of gas powered generating equipment, being in the business since 1881. Gen-sets are noted for their market leading efficiency and proven track record for dependable and predictable service, thus making them the most cost effective, efficient solution.
Successfully bidding to replace the St James Hospital unit recently, Edina installed and maintains the MWM TCG2020 V12K engine which generates 1MWe and is
specially enhanced by MWM for its steam capacity which is used by the hospital for heating and sterilisation. The ability of these systems to provide Low Pressure Hot Water (LPHW) and steam makes them a particularly attractive proposition for hospital applications. Fuelled by natural gas, the energy and carbon savings are apparent instantly with typical pay-back in approximately three to four years.
Reducing bills in Liverpool At Liverpool and Broadgreen NHS
Trust, two MWM TCG2032 V12 CHP units were ordered by Dalkia from Edina in 2001 to reduce energy and carbon emissions whilst maintaining a high level of availability for this critical site. Each unit is rated at 2.65MWe, one of the largest installations of its type in the country at the time. The CHP systems provide power,
LTHW (Low Temperature Hot Water), HTHW (High Temperature Hot Water) and steam to the hospital. Throughout its installation, the system has performed to a consistently high standard achieving an average availability of 95% over this period. The installation recently received a “highly commended” award at the 2012 CHPA Awards ceremony as it was one of the first of its type at this size using reciprocating gas engine technology in lieu of the conventional gas turbine approach (the industry standard at the time of installation). “This project has not only significantly reduced the Trusts’ energy bill across both hospital sites, but also enabled us to

substantially improve the reliability and resilience of our electrical supplies,” commented AJ Wilkes, Executive Director of Finance Royal Liverpool and Broadgreen University Hospitals NHS Trust.
Reduction of emissions in
Glasgow Uptake of this technology has increased dramatically with projects for Altnagelvin Area Hospital and Craigavon Hospital in Northern Ireland, Chorley and South Ribble
