The energy centre was built to meet rising energy needs while reducing the hospitals’ operating costs by 15%. It replaced an existing CHP plant.
Matching technologies to needs
The new facility uses a gas turbine CHP unit to meet base load, with a biomass steam boiler fuelled by locally sourced wood chip meeting higher winter demand and three dual fuel (gas/oil) boilers kicking in to meet peak demand. This is a unique combination of technologies in Europe. Operating efficiencies have delivered annual operational savings of 9830t CO2e and £2.95m, at 2010 prices, beating the efficiency target by 24%.
