Energy: Power Stations

Volume 712: debated on Tuesday 7 July 2009


Asked by

To ask Her Majesty's Government what would be the likely cost of building new power stations to provide 25 gigawatts (25,000 megawatts) of electricity by (a) coal, (b) gas, and (c) nuclear power; and what would be the likely load factor of the new plants in each case. [HL4691]

The cost of building power stations depends on a number of factors which investors will take into account in deciding whether to build coal, gas or nuclear plants. These include the cost of raising finance, the length of construction as well as the materials. Load factors will depend on commercial decisions taken by companies when assessing how to run their power stations—these will be driven by fuel and other operational costs relative to electricity prices.
