With the second-largest road network in the world, India's road transport contributes towards nearly 64% of the country's overall goods movement and caters to around 90% of India's total passenger traffic. This provides a huge opportunity to decarbonize the transport sector but there are also challenges. Government of India has taken proactive measures towards fostering a clean, connected, shared and cutting-edge transportation system by providing policy and regulatory support.

5 As India embarks on this ambitious journey towards sustainable mobility, a robust CHARGING infrastructure will play a pivotal role. It must be understood that sector coupling between the energy and transport sectors is vital for e-mobility. With the growing number of EVs, the need for development of large network of CHARGING infrastructure will only increase in the future. To support deployment of CHARGING infrastructure in the country, the Government of India has allocated a total fund of INR 1000 Crore under the FAME II scheme. Under public procurement, Department of Heavy Industry (DHI) has sanctioned 2,636 EV CHARGING Stations, in 62 cities across 24 States/UTs and 1,544 such stations on highways under FAME II.

6 Scheme. EV CHARGING is a delicensed activity in India and the Ministry of Power (MoP) has published revised guidelines for CHARGING infrastructure for ELECTRIC VEHICLES to facilitate the deployment of CHARGING infrastructure. Apart from this, several states have announced targets for EV deployment including special EV tariff to incentivize EV CHARGING in India. For the uptake of EV adoption in India, a major challenge of integrating the CHARGING infrastructure with the electrical network needs to be tackled. The continued development of EV CHARGING infrastructure and its INTEGRATION will depend, among other things, on policy and regulatory environment, which must also account for grid stability. I am glad to know that the Deutsche Gesellschaft f r Internationale Zusammenarbeit GmbH (GIZ) has initiated a study focused on EV CHARGING infrastructure, related policy and regulatory measures, grid INTEGRATION of EVs, critical international review from eight countries, and way forward for smooth INTEGRATION of EV CHARGING infrastructure with the Indian grid.
