We don't have it, we rely on imports - about 13% of our needs..
Overnight an interconnexion between France and the UK was on fire and closed down. This morning wholesale electricity jumped 19% to £475 per megawatt hour (MWh). That interconnect normally supplies 2GW but will be restricted to 1GW, once repaired, this will last over winter.
We should not be in this position. A mature economy such as the UK's should be self-sufficient, and more, in its energy needs and this fire shows us that we are not. The fire also shows us that renewables cannot pick up the slack, we need a mix of generation. We certainly need more nuclear, especially for the future.
