Under the agreement, Siemens will run the Source London operations, including the registration of drivers and the network of charging points, which will be strategically located across the capital.
TfL also said Siemens will run Source London's back office through to March 2014 "at no cost to taxpayers".
Drivers of electric vehicles will initially be charged £100 to join Source London, which will provide free charging at all its points.
By the end of 2013, the number of charging points is expected to grow from the current 250 to at least 1300 in public locations, installed by over 40 partners ranging from supermarket chains Sainsburys and Asda, to Scottish and Southern Energy and London boroughs.
“One of the biggest hurdles to greater use of electric vehicles has been a lack of charging points. But now Londoners will see Source London points popping up in locations all over the capital,” saod Mayor Boris Johnson.
Nick Fairholme, TfL interim director of congestion charging and traffic enforcement, said the launch demonstrated the company's commitment to reducing London's transport emissions.
"Even in these economically challenged times, the mayor and TfL continue to work to make London one of the greenest cities in Europe," he said. "London already has the highest number of EVs in the UK; Source London, in conjunction with the new vehicles coming to market this year and the government consumer grant, will keep us in the lead."
London already has the highest number of electric vehicles in the UK and, now coupled with the Government’s £5000 grant for electric vehicles, hopes to maintain its leading position.
