Question

To ask the Secretary of State for Energy and Climate Change, what the (a) fuel type and (b) individual generating capacity expressed as a proportion of the total maximum UK demand for electricity is for each (i) operating and (ii) mothballed UK-based nuclear generating unit.

The fuel type for UK nuclear electricity generation is Uranium.

Total simultaneous maximum load (total peak demand) met in 2013 was 51,811 MW in Great Britain – (Northern Ireland is excluded because their network is attached to the Irish Grid). [1]

Table 1 shows the current operating plants alongside their percentage of the total peak GB demand mentioned above. We do not have any mothballed UK-based nuclear generation.

Table 1 – Operating plants installed capacities (Sum total may not add up due to rounding)
