The Mayor's office says that the Northern Line extension will reduce pressure on Vauxhall station and existing Northern Line services, in addition to boosting the area's economy.
It is expected that work on the line could begin by 2015, with services in operation by 2020.
A consultation on the plans is already underway.
The Chancellor has announced a £1 billion pound loan to London Underground to finance the extension of the Northern Line to Battersea.
Mayor of London Boris Johnson said:
“I am delighted that after months of intensive discussions and hard work we have got the go ahead from Government on financing an extension to the Northern Line, which is hugely significant as Nine Elms is one of the areas with the greatest prospect for new development in the whole of the capital.
"It will be an incredible confidence boost for developers preparing to invest there and it will also be a considerable boost for local people who will benefit from the new Tube link.”
The Chancellor has announced that the Northern Line will be extended to Battersea, as part of his Autumn Statement.
George Osborne also announced £1 billion of investment in the country's roads, including upgrades to the A1, the A30 and the M25.
