UK grid-lock? | Top GE Vernova exec sounds alarm bells over getting Scottish wind power south | Recharge
Expanding renewable generation on the scale that the UK needs to help meet its climate targets will require urgent market and regulatory reform, while the country could still face the risk of severe curtailments due to congestion or limitations in transmission capacity, according to a study by power technology group GE Vernova.
The GE Vernova analysis examines three different energy generation and transmission investment scenarios and models pathways considering the build-out of renewables, nuclear, storage and lower-carbon thermal generation across the UK, which aims to decarbonise its electricity system as soon as 2035.

Over the next decade, U.S. offshore wind power is expected to grow from a single 30-megawatt wind farm off Rhode Island to more than 2,000 MW of capacity along the Atlantic Seaboard. There are contracts for wind power off the coasts of Massachusetts, Connecticut, New York, Maryland, New Jersey, Rhode Island, and Virginia.
The National Renewable Energy Laboratory has estimated the United States has over 4,000 gigawatts (GW) of offshore wind potential, enough to power the country four times over.
The growth in part being spurred by state solicitations, including in New York, where then-Gov. Andrew Cuomo (D) set a commitment of 9,000 MW of offshore wind by 2035, and in Connecticut, where in June 2021, Gov. Ned Lamont (D) signed legislation authorizing the construction of 2,000 MW of offshore wind by 2030.
The offshore development is also being driven by an investment tax credit set to end in December 2019 and is equal to 12 percent of expenditures. U.S. Sens. Susan Collins (R-Maine) and Tom Carper (D-Del.) have introduced a bill to extend the tax credit for up to eight years.
The Interior Department has held eight competitive lease sales that resulted in 15 offshore wind leases over 1.7 million acres that has the potential for 21 GW of capacity. In February 2022, the Bureau of Ocean Energy Management completed a bidding process that realized $4.37 billion for 488,000 acres across six lease areas in federal waters off New York and New Jersey.
Projects have also been proposed off the Southeast coast, off California and Hawaii, and for the Great Lakes.
