Pembroke CCGT

Client: Alstom

Project: Pembroke Combined Cycle Gas Turbine Plant (CCGT).  Construction and installation of the largest and most energy efficient CCGT plant in the UK, supplying up to 3 million homes.

Handover Date: January 2011

Materials management - Many of the reinforced concrete elements required were identical, so the site team designated an area within the site and set up a production line (similar to that used in manufacturing industry).  A precast yard and batching plant were set up on site and used to successfully manufacture many construction elements including 895 drawpits/manholes, 2200 precast sleepers, 2900 precast fingered lids.  This effected waste, resource efficiency, quality, and time improvements.  Local communities and roads were relieved of heavy traffic as a result. 

Wastewater management - The close proximity of Pembroke Bay rendered wastewater a significant potential environmental aspect.  Project wastewater was directed through oily water separators, bypass seperators, and/or foul treatment units.  All wastewater treatment units were manufactured on site.
