NATIONAL GRID AWARDS COSTAIN CONTRACT TO UPGRADE

PETERBOROUGH AND HUNTINGDON COMPRESSOR STATIONS

21 November 2016

Costain, the engineering solutions provider, has been awarded a contract worth £113 million by National Grid to upgrade its Peterborough and Huntingdon compressor stations. The programme of work is part of National Grid's Emissions Reduction Project and will conclude in 2021.

Following completion of a successful Front End Engineering Design (FEED) project, Costain will now undertake the detailed design, decommissioning, build and re-commissioning of the two compressor stations. The work will ensure both compressor stations comply with the Industrial Emissions Directive and Pollution Prevention and Control regulations. The project will also increase system resilience and reduce overall risk on the National Transmission System by replacing aging assets with modern, efficient equipment.

Andrew Wyllie CBE, Chief Executive explained:

"This is another example of Costain's strategy in action. From design and delivery to programme management, we are providing a full range of engineering solutions to National Grid to help them meet national needs by providing a secure and sustainable energy supply."
