India’s projected transition to electric vehicles (EVs) will produce major changes across its automotive manufacturing sector. These changes risk disrupting the relationship between large enterprises (comprising original equipment manufacturers [OEMs] and large Tier-1 automotive component manufacturers [ACMs]) and ACMs that are micro, small, and medium enterprises (MSMEs). Currently, over 75–80 percent of ICEV components are manufactured by domestic MSMEs and supplied to large enterprises. However, about 60–70 percent of EV components are imported because MSMEs lack the capacities and technological capabilities to produce them. Thus, accelerating the transition risks inequity by leaving MSMEs behind. There is a strong interdependence among large enterprises and MSMEs in the current ICEV ecosystem. A business case can thus be made for OEMs and large Tier-1 ACMs to help their MSME suppliers diversify to EV component production. This paper identifies a clear business case and outlines practices for large enterprises to support a just EV transition for their MSME suppliers.
