The government has given the go ahead to build Britain's first new nuclear power station in a decade at Hinkley Point near Bridgwater.
The announcement will see an investment of £16 billion, and the creation of 25,000 jobs.
As part of the deal, the government has agreed a so-called strike price with EDF for the amount it gets per megawatt hour of electricity.
The figure settled on today is £92.50 which is more than double the current market rate, the Prime Minister said it was a good deal.
David Cameron has insisted that plans for the UK's first nuclear power station in a generation at Hinkley was "not a deal at any price".
