PROJECT BACKGROUND
Guy’s and St Thomas’ has a staff of 13,000 managing two million patients each year. With a 900 year history it is one of the oldest and largest hospitals.
Recognising the potential for CHP technology to achieve their sustainability targets and make significant financial savings they turned to NIFES for specialist assistance.
OUR APPROACH
NIFES began with a detailed feasibility study for the two hospitals that showed the enormous potential benefits, then produced a Full Business Case and helped the Trust to secure a £10m grant from the Department of Health’s Energy and Sustainability Fund.
3MWe CHPs were installed in both hospitals, each connected to waste-heat boilers and heat exchangers in nine plantrooms. The steam mains and high-voltage networks had to be extensively reconfigured whilst ensuring the hospital’s activities were never disrupted.
Challenges with the available space, noise restrictions and tough Planning criteria were all successfully overcome.
SUMMARY
Project Results
The completed installations are producing CO2 savings of 20% – double the client’s target. The annual savings of £1.7m helped to fund the biggest instrument sterilising facility in Europe which also uses the steam generated by the CHP.
”This has been one of our largest projects, but it supports many of our key objectives. It is the most effective way of cutting our carbon footprint, and the savings can go back into providing care for our patients.
