Northern line extension to Battersea

The Northern line extension to Battersea is a proposed extension of the London Underground to Battersea in South London initially to Battersea Power Station from and then, possibly, onto Clapham Junction. The extension would form a continuation of the branch of the line.

The extension is proposed as a privately-funded project by the site developers, Treasury Holdings, with contributions from other sources such as the new US embassy. The plan has been given planning permission and could be open by 2015.

Battersea would be the new southern terminus, extending the line from Kennington with a new station at Nine Elms on Wandsworth Road. . It would be in Travelcard Zone 2.

Nine Elms tube station may be situated by the junction of Wandsworth Road and Wilcox Road, at a site that is currently used as a car park for the Nine Elms branch of Sainsburys. However a May 2010 consultation put forward four proposals (two slightly different locations for Nine Elms, an interchange at station (for the Victoria line) instead and a direct link with no in between station. In addition to serving the mostly residential communities, the Nine Elms would also provide improved access for the nearby New Covent Garden Market and the proposed new Embassy of the United States in London.

Major landowners and council leaders in London's Nine Elms area said in November 2010 that the extension could be funded largely from developer contributions and would provide an economic windfall for the entire Nine Elms regeneration area. At the inaugural meeting of the Nine Elms and Vauxhall Strategy Board, members were told that a study commissioned by the Greater London Authority (GLA) had put the total cost for new link at £560 million.

On 11 November 2010 Wandsworth Council granted planning permission for a two station extension of the Northern Line from Kennington with one of two new tube stations located at the power station site and the other at Wandsworth Road.
