National Grid has awarded Alstom Grid an £18M contract for the design, supply and commissioning of two 400kV boosters to be used with wind energy projects.
The North West of England is experiencing a huge surge in the growth and development of wind farms located off the shore of Cumbria. The 400kV Quadrature Booster implemented at Penwortham will allow National Grid to control the increased power flows generated by them and optimise the load sharing in this part of the network.
The first Quadrature Booster, which has been designated by National Grid as a spare unit, will be designed and manufactured in 2012, whilst the second will be manufactured in 2013 for installation at Penwortham Substation near Preston, Lancashire.
Each Quadrature Booster comprises two transformers, individually weighing around 270T. Once installed at site, filled with oil and connected together they will have a total weight in the region of 1,040T.
The units will be built at Alstom Grid’s transformer factory in Stafford where the contract will create additional work for the 300-strong workforce over the next three years.
