NEW DELHI: 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.“The government is considering amendments to Urban and Regional Development Plans Formulation and Implementation Guidelines, 2015 and Model Building By-Laws, 2016 to accommodate promotion of electric vehicles in infrastructure planning and power distribution services norms,” said the official.The proposal also includes increasing electricity load for all buildings. India plans to shift one-third of its vehicle base to electric fleet by 2030.Sohinder Gill, director corporate affairs at Society of Manufacturers of Electric Vehicles, said the electric vehicle industry has seen a decent leap in 2017-18, especially in the electric two-wheeler segment. “The numbers indicate that citizens are accepting electric vehicles as an economical as well as a cleaner mode of transportation in comparison to conventional vehicles. However, the absence of adequate finance mechanism, price gap between an electric two-wheeler and petrol two-wheeler, awareness among citizens are challenges, which need immediate redressal,” he said.In the four-wheeler segment, lack of infrastructure, ambiguity over policy remain a major deterrent, which is holding the segment back.This year looks positive, especially for the electric two-wheeler segment and we anticipate the sector to perform better than last year, Gill said.Alekhya Datta, fellow and area convenor, electricity and fuels division at The Energy & Research Institute, said shifting 25% of the vehicle base to battery operated fleet will require additional 20.7 terawatt hours of electricity and would generate Rs 7,000 crore additional revenue to power discoms.ET had earlier reported that the government is preparing a fresh policy for promotion of electric vehicles. According to the proposal, the government will begin creating favourable ecosystems in nine polluted cities with population of over 4 million, and gradually move to cities with population of one million-plus.
