Johnny Ronan and Richard Barrett’s Treasury Holdings along with Transport for London are holding public consultations, starting this week, on an extension to London Underground’s Northern Line. This would see the line extended from Kennington to Nine Elms and Battersea.

Treasury is obviously hoping the project will go ahead because it is crucial to allowing the development of Battersea Power Station. The Qatari royal family is expected to become involved in the Battersea project imminently as a joint venture partner.

As part of the consultation, 40,000 leaflets have been circulated to local residents. “The iconic Battersea Power Station and its surrounding area have lain dormant too long but the incredible potential of the area could be realised by a privately funded extension of the Tube,” London mayor Boris Johnson said last week.

The private funding will come from levies on development within the area, and the redevelopment of the power station in particular will play a key role.

Documents circulated in March suggest the mayor’s office anticipates the regeneration of the power station to result in development levies of more than €240m, that would be used for infrastructure like the Northern Line extension.

Rob Tincknell, managing director for Treasury Holdings in Britain, said that the extension is necessary for the full regeneration of the Nine Elms Opportunity Area and that it will integrate the area into the rest of central London.
