National Grid: Carbon Emissions

The question

To ask the Secretary of State for Energy Security and Net Zero, what recent estimate his Department has made of the cost of decarbonising the electricity grid by 2030.

Answered by Michael Shanks

NESO's analysis confirmed delivering clean power by 2030 is deliverable, more secure, and could see a lower cost of electricity, and lower bills.

We are committed to working with industry to grow our clean energy system with once-in-a-generation levels of energy investment – an estimated £40 billion, the vast majority of which will come from the private sector.

The government is leveraging public finance institutions like the National Wealth Fund and Great British Energy to catalyse private investment.
