Unfortunately for British nuclear advocates - their plants have substantially worse economics than US ones. Hinckley C was granted its license in 2012 and authorized in 2013 with a strike price of £89.50 per MWh when the projected cost was £7 billion -- it's now scheduled to be completed in 2030 at a cost nearing £50 billion. There is literally no amount of baseload generation worth that cost.
The wholesale price coming out of Hinckley will be higher than the retail price in most of the US.
What made the cost to balloon so much, and the timeline to set so huge a delay? Technical problems? Regulatory hurdles? Locals resisting? Running out of money?
