CCGT Generating Station, Pembrokeshire

Pembroke is one of the largest and most energy efficient Combined Cycle Gas Turbine (CCGT) power stations in the UK and will form an important part of the energy supply mix as older plants are phased out. The £1bn project, owned and commissioned by RWE npower, will produce 2,000MW and supply up to 3 million homes.

Alstom chose John Sisk & Son for their innovative and coherent solution to the civil engineering work. This award follows on from the relationship developed between Alstom and John Sisk & Son on the power station project in Aghada, Ireland.

Detailed control of the programme and close relationships with client and supply chain enabled Sisk to bring the clients a cumulative saving of 8 weeks against our original 54 week programme.  The work incorporated the construction of the substructure and reinforced concrete work for the five turbine halls together with the associated cooling water pipework, site services, station control and ancillary buildings.

Community engagement is of paramount importance to Sisk, Alstom and RWE npower. John Sisk & Son submitted detailed plans to minimise disruption to the area and to work closely with RWE npower’s Local Liaison Committee (LLC) to promote local employment opportunities and keep local communities regularly informed of the work schedule.
