PROJECT DETAILS
- Energy appraisal
- Design
- Contract management
PROJECT BACKGROUND
Facing a shortage of power, escalating running costs, and government demands for reduced emissions, The Trust turned to NIFES for a solution.
OUR APPROACH
Having carried out a full energy appraisal to establish the electrical base load, a gas-fired CHP was selected, comprising:
- 1.8 MWe gas-fired Jenbacher engine, continuously generating electricity
- HV/LV ring main alterations to accept the new power supply
- Waste-heat boiler generating steam from engine exhaust gasses
- Cooling jacket heat piped to the plantrooms for heating and hot water
Particularly challenging was the assessment of over-pressure risks in the CHP exhaust system in light of changing NFPA68 guidance published after the contract was let. The capital value of the CHP was £2.3m
In a separate contract, the hospital’s ageing stand-by generators were replaced with two 1,250kVA oil-fired engines in purpose-built acoustic enclosures. The capital cost was £1m.
SUMMARY
Project Results
The Trust’s aspirations were all met with significant carbon emission reductions and running cost savings that amounted to almost £2,000 every day!
