The plan would provide two new Tube stations – one at Battersea Power Station and another just off Wandsworth Road. They would connect to the rest of the Northern Line at Kennington Station.
Wandsworth Council believe it would support 25,000 new jobs and more than 18,000 new homes in Nine Elms, with journey times to and from the West End and the City cut to 15 minutes.
Wandsworth Council leader Ravi Govindia said: “This vital Tube link will breathe new life into Nine Elms, creating thousands of jobs, thousands of homes and a new riverside town centre at Battersea Power Station. It will revive the last dormant district of central London and yield billions of pounds in new economic growth and tax revenue.
“The council has championed this infrastructure project for the last five years and we are now within touching distance of delivery. It’s incredibly exciting for Wandsworth.”
If planning powers are obtained from the Government, and a funding package is in place, then construction of the Northern line extension could begin in 2015 with the two new stations opening in 2020.
The extension would reduce pressure on Vauxhall station and provide relief to the existing Northern Line south of Kennington.
Michèle Dix, Managing Director of Planning for Transport for London, said: “We look forward to fully outlining our proposals for the Northern line extension.
“This public inquiry is part of the planning process. If this transport link goes ahead it would create access to the Tube for thousands of people in south London as well as helping to support new jobs and homes in the area.”
The inquiry is expected to last for four weeks.
