The UK currently has 75 GW of installed electricity generating capacity.
There are various estimates but some industry estimates suggest that up to £100 billion investment in new electricity generation capacity will be required over the next 10 years to replace those power stations expected to close and build the new renewable generation needed to meet the electricity sector's contribution towards the EU's 2020 target for 20 per cent. of energy consumption in the UK to come from renewable energy sources.
