Timeline: How the Hinkley Point C development has played out so far

A guaranteed price for the electricity generated at the power station is expected to be around £15 per megawatt hour less than the £92.50so-called strike price awarded to EDF for the Hinkley Point C nuclear power station being built in Somerset.
