Summary

National Grid commissioned Pick Everard to renew and upgrade all of the critical cooling systems and plant items serving its National Electricity Control Centre, as well as associated computer apparatus rooms.

The brief

The project involved replacing the computer room air conditioning (CRAC) systems serving the main control centre for electricity distribution throughout the UK. As a critical part of the national power infrastructure, the site had to remain operational throughout all phases of the work.

Our response

Our designs allowed rolling replacement of dilapidated equipment with rapid deployment in a live environment. We also made it possible to carry out planned maintenance on critical systems without compromising resilience or needing temporary support. By using ethernet-based control systems, we improved monitoring and facilitated targeted preventative maintenance.

Key facts

  • We maximised chiller operating efficiencies.
  • We incorporated EC/DC fan technologies and improved BMS strategies.
  • We incorporated comprehensive energy monitoring.
  • We achieved a 20% improvement in power usage effectiveness.
