Transport for London (TfL) is preparing to spend £18 million on upgrading London's power grid, in order to supply electricity to charging ports for the first generation of electric black cabs.
In an effort to cut down on the toxic air pollution in the capital, all new black cabs must be battery powered from 1 January 2018.
300 rapid charge ports will be installed by 2020, by Centrica, the owner of British Gas.
75 charging ports will be installed by the end of this year, and some of the ports will be open to electric vehicle owners. Others will remain exclusively for electric cab users.
Taxi drivers who drive a car 10 years or older will be able to claim up to £5000 from TfL towards the cost of a zero-emission taxi, which are being built in Coventry.
