• FAME I (2015-2019): Focused on demand creation through subsidies for EVs and supporting infrastructure development. Approximately 371,000 EVs were supported with total incentives of around ₹634 crore (~USD 79.6 million) as of July 2021, and 427 charging stations were installed under this phase.
  
• FAME II (2019- 2024): Emphasizes the electrification of public transportation and the development of charging infrastructure. Under FAME II, ₹1,000 crore (~USD 125.6 million) was allocated for the development of charging infrastructure in the country. FAME II Scheme has been phased out & now replaced with PM E-Drive Scheme.

• PM Electric Drive Revolution in Innovative Vehicle Enhancement (PM E-DRIVE) Scheme (Oct, 2024 – Mar, 2026): In October, 2024, Government of India approved the “PM E-Drive Scheme”, effectively replacing the older “FAME” scheme and it will remain in force until March 31, 2026. Its primary aim is to accelerate the adoption of electric vehicles (EVs), establish charging infrastructure, and build a robust EV manufacturing ecosystem in the country. PM E-Drive is the current primary scheme for EV incentives in India. The PM E-DRIVE scheme is proposed to be implemented through Subsidies, and grants for creation of capital assets. e-2W, e-3W, e-ambulances, e-trucks and other new emerging EV categories will be eligible for support.

State-Level Initiatives

Several Indian states have introduced their own EV policies, offering incentives such as tax exemptions, subsidies, and support for charging infrastructure development. For instance, Delhi’s EV policy provides subsidies for the purchase of EVs and aims to establish a robust charging network across the city.

Assessing Demand and Setting Targets for EV Charging

Accurately assessing the demand for electric vehicle charging infrastructure is crucial for effective planning and resource allocation.

Estimating EV Growth

India’s EV market is expected to reach $48.6 billion by 2030. This anticipated growth necessitates a proportional expansion in charging infrastructure to support the increasing number of EVs.

Setting Infrastructure Targets

To meet the projected demand, India will require approximately 1.32 million charging stations by 2030, necessitating the installation of around 400,000 chargers annually. citeturn0search2 Setting such ambitious targets underscores the need for coordinated efforts between government agencies, private enterprises, and other stakeholders.
