While its great that we are getting more electricity from low carbon sources and that we have mechanisms to nudge people to shift demand, the costs are a bit more complex. We are still paying for that electricity because of the agreed strike price, and then paying again for people to take it off the grid. The strike price is now essential, as it would be foolish to build a new wind farm that produced most of its output at a time when no one wants to buy it. The difference between strike price between wind (For 2025 up to £73 for offshore, £176 floating) and nuclear (£92 for HPC or £89 with Sizewell C) is not huge. Fun fact strike prices are always quoted in 2012 pounds.
