REMEMBERING Stephen Crabb, the Pembrokeshire Conservative, who opened Pembroke combined cycle gas turbine (CCGT) Power Station and knowing that gas-fired power stations are cleaner than coal-fired power stations, it surely follows that voters will be very interested to know where Mr Crabb and other politicians stand on the Shale Gas issue?
To be sure, the relatively new (December 2009) Marchwood Power Station on the River Test overlooking the port of Southampton is also a natural gas CCGT power plant. Modern generators of this kind represent advanced technology as they offer high operating efficiencies and low emissions, and will operate at approximately 58% fuel efficiency, compared to around 30-35% efficiency in the case of the oil-fired power station which was formerly on the site. Marchwood Power Station has two gas turbines, cost £380 Million, can supply nearly one million homes (how many ineffective wind generators would be needed to fully compete - that’s when the wind is blowing of course?), and is one of most efficient power stations in the UK.
The term ‘combined cycle’ refers to the use of two processes to produce electricity.
The burning of natural gas is the first. The recovery of heat from the waste gases to produce steam to drive a steam turbine is the second.
Together, these processes capture much more of the energy in the gas.
Modern CCGT plants of this kind represent advanced generating technology as they offer high operating efficiencies and low emissions – Pembroke CCGT Power Station has more than sufficient capacity to supply the whole of Wales, the remainder available for exporting to England and thus renders ineffective Welsh wind farms redundant - therefore perhaps Welsh MPs would be good enough to enlighten Welsh readers to their views on Fracking, gas-fired power stations and the absurdity of wind farms?
