The government proposes to amend building by-laws to make it mandatory to set up electric vehicle charging stations in residential and commercial buildings and parking lots. The proposals include offering round the-clock charging infrastructure facility to all electric vehicles in residential buildings, setting up charging bays at 20% capacity of all vehicles, on-spot metering and payment services in both commercial and residential buildings, a government official said. Town and Country Planning Organisation under the ministry of housing and urban affairs has prepared draft enabling guidelines for electric vehicle charging infrastructure, based on which governments shall amend their building by-laws and master plan regulations. These will be applicable to residential, institutional buildings, multi-level parking complexes, bus terminals and service stations, he said.
