Fossil‐fuel consumption has tremendously escalated in recent decades, resulting in a significant rise in harmful emissions, contributing to global warming and environmental contamination. Transportation sector is one of the major contributors to rising emission levels across the globe. The ever‐increasing vehicular count has made the development and deployment of eco‐friendly substitutes such as electric vehicles (EVs) imperative. Infrastructure development requiring a high investment becomes a major roadblock for the adoption of EVs. This work focuses on the much‐needed transition to EVs and proposes a design for specialized EV‐charging stations. Energy requirement for the proposed stations is partially met through rooftop photovoltaic plants. It also takes into consideration the present and future vehicular topology along with a differential pricing strategy adopted for effective load management. Three different categories of electric vehicle supply equipment (EVSE) have been analyzed. Using the case for the state of Delhi in India, that houses over 10 million vehicles. A detailed techno‐economic analysis reveals that the proposed design yields a yearly profit of $63 680 and allows the charging stations to recover their setup costs in 2.5 years. Level‐2 EVSE with an output of 22 kW is most efficient and results in reducing greenhouse gas emissions by 104 t.
