The approval for the biggest single investment for the electricity transmission infrastructure in Britain comes as part of the regulator's scheme, opens new tab to get new offshore wind energy to the market and delivery it quickly.
Ofgem said the Eastern Green Two project for a subsea 'superhighway' with an underground 436 kilometre cable between Scotland and Yorkshire will be able to power up to 2 million homes across Britain.
The construction of the project - a joint venture between National Grid Electricity Transmission and SSEN Transmission - is expected to begin later this year, and the transmission line will be operational in 2029, the regulator said.
