The Ministry of Power has issued the revised consolidated guidelines & standards for charging infrastructure for electric vehicles on 14th January 2022. The objective of the promulgation is to enable a faster adoption of electric vehicles in India by ensuring safe, reliable, accessible and affordable EV charging infrastructure and eco-system.

Key Highlights of the Guidelines and Standards

  • Owners may charge their electric vehicles at their residences and offices using their existing electricity connections.
  • Exhaustive compliance requirements for public EV charging stations have been clarified.
  • Connection would be provided to public EV charging stations within 7 days in metro cities, 15 days in other municipal areas and 30 days in rural areas.
  • The ceiling of Service Charges to be charged by such charging stations would be fixed by the state governments.
  • The tariff for supply of electricity to public EV charging stations would be a single part tariff and would not exceed the “average cost of supply” till 31st March 2025.
  • Through open access, public EV charging station or chain of EV charging stations may obtain electricity from any power generation company.
  • BEE would develop and maintain a national online database of all the public EV charging stations in consultation with State Nodal Agencies
  • Public EV charging stations would be required to tie up with at least one online Network Service Provider to enable advance remote/online booking of charging slots by EV owners.
  • At least one EV charging station shall be available in a grid of 3 Km X 3 Km. Furthermore, one EV charging station shall be set up at every 25 Km on both sides of highways/roads.
  • A phase wise installation of EV Charging infrastructure for mega cities and big cities has been envisaged under the guidelines.
