Electric and cleaner

The report examines how India can transition to cleaner EV charging by utilizing time-of-day (ToD) tariffs, green tariffs, rooftop solar, and open access. While states like Assam, Bihar, Maharashtra, and Madhya Pradesh use ToD tariffs to encourage charging during solar hours (10 AM to 4 PM), the prevalence of nighttime home charging and limited public charging infrastructure (approximately 26,367 stations) hinder effectiveness. Green tariffs are currently restricted to consumers with loads over 100 kW, and while rooftop solar is gaining traction in Delhi and Bengaluru, high deployment costs remain a barrier. Open access for renewable energy is available for operators with a 100 kW load, but high upfront and third-party charges limit its adoption.

• Time-of-day (ToD) tariffs are being used in several Indian states to shift EV charging to solar-rich hours, typically between 10 AM and 4 PM, through rebates, while applying surcharges during evening peaks. This is implemented in states including Assam, Bihar, Maharashtra, Madhya Pradesh, Karnataka, and Tamil Nadu.
• The effectiveness of ToD tariffs is limited because most EV charging occurs at home during late evenings and nighttime, and the public charging station (PCS) network is moderately deployed with approximately 26,367 installations nationwide.
• Green tariffs allow consumers to procure certified renewable energy by paying a premium over the standard tariff, but they are currently inaccessible to home users as they require a connected load greater than 100 kW.
• Rooftop solar is an emerging clean energy source for charging stations in cities such as Delhi and Bengaluru, though high deployment costs lead to higher charging prices.
• Since June 2022, EV charging station operators with a minimum sanctioned load of 100 kW can purchase green energy via open access, but adoption is restricted by high upfront costs and third-party open access charges.
