Energy companies have promised to spend up to £77bn over five years to help rewire to Great Britain’s electricity infrastructure in the global race to shift from fossil fuels to clean electricity.
The companies that own the high-voltage power system – National Grid, SSE and ScottishPower – have submitted the spending plans to the regulator Ofgem for the period from 2026 to 2031, which could support about 100,000 jobs.
