Energy firms to spend £70bn to rewire Great Britain’s electricity grid

National Grid, SSE and ScottishPower submit plans amid global race to shift from fossil fuels to clean electricity

Energy companies have promised to spend almost £70bn over five years to help rewire 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 spending plans totalling about £68bn to the industry regulator Ofgem for the period from 2026 to 2031, which could support about 100,000 jobs.
