  • Off-site construction – minimises time on site and carbon footprint
  • Zero high grade heat dump
  • Maintain security of power supply

Welsh government incentive to reduce energy consumption and carbon emissions in leading hospitals Withybush General and Prince Philip utilise Combined Heat and Power (CHP) technology, ensuring the best possible spend on NHS money. The government incentive forms part of the Hywel Dda University Health Board (UHB) to reduce the rise in energy costs within the NHS.

Worth up to £9.3million, the funding will future proof Withybush General and Prince Philip Hospitals to significantly reduce energy consumption, provide long term security of power and achieve high standards of environmental performance.

The project to replace and deliver a new CHP plant at Withybush General Hospital and Prince Philip Hospital was awarded to energy management service provider British Gas. Through a competitive tender process British Gas awarded Edina Group the project to design, supply, install and maintain the two CHP plants. The scope of work proposed at the central boiler house included the installation of two 600kW MWM TCG 2016C V12 CHP gas engines.

Edina’s CHP installations and on-going maintenance obligations is a key part of this project that will support the Health Board in meeting its carbon and energy saving objectives.

The engines included exhaust heat recovery to produce steam, used for hygiene and sterilisation, and engine jacket cooling recovery to produce Low Temperature Hot Water (LTHW). Both MWM gas engines have the potential to deliver an annual energy saving of up to £250,000 and a carbon emission reduction by 1,500 tonnes.

MWM are world renowned for achieving maximum electrical and thermal efficiency, low operating and servicing costs and high reliability and availability. Edina also containerised the engines at its manufacturing facility based in Lisburn, Northern Ireland and supplied all auxiliary equipment and were both constructed to support all equipment inside such as the silencers. The waste heat recovery steam generator was located in the boiler house.
