In order to ensure that electricity demand gets evenly distributed throughout the day, TPDDL is planning to introduce differentiated tariff and time-of-day metering to incentivise the public to charge EVs during off-peak hours.
Aiming to tap the growing business of electric vehicle (EV) charging, Tata Power Delhi Distribution (TPDDL) is set to spend about Rs 600 crore to upgrade its power transmission network and install 1,000 EV charging stations across its distribution area in New Delhi. Speaking to FE, the company’s CEO and MD Praveer Sinha said a minimum of 20% of the network cost is needed to prepare the infrastructure for the surge in power demand anticipated from more EVs on roads. Charging fifty electric public buses can raise the demand load by 50 MW, as per an estimate. Sinha noted that since there could be abrupt changes in electricity consumption pattern with EV charging coming into the picture, TPDDL is working to implement software for balancing the grid according to time and requirement. In order to ensure that electricity demand gets evenly distributed throughout the day, TPDDL is planning to introduce differentiated tariff and time-of-day metering to incentivise the public to charge EVs during off-peak hours. The present rates for EV charging are at par with the higher domestic slab category of Rs 6-7/unit. With time-of-day metering, the rates can drop to as low as Rs 3-4/unit, and can go up to Rs 10/unit during peak hours, Sinha noted.
The discom is targeting bus depots and other public parking areas in shopping malls and metro stations to set up EV charging stations. It is currently discussing the possibilities with New Delhi Municipal Corporation and the Delhi Metro Corporation. Apart from cutting down emissions, augmented uptake of EVs would be a blessing for the Indian power generation industry which is reeling from low capacity utilisation in the face of tepid power demand growth. The installed power generating capacity in the country is more than 3,30,000 MW while peak demand stays around 1,50,000 to 1,90,000 MW. According to Bloomberg New Energy Finance, electricity consumption globally from electric vehicles will rise to 1,800 billion units (BUs) by 2040 from 6 BU in 2016. It also estimated that on the back of falling battery prices, 54% of new car sales and 33% of the global car fleet will be electric by 2040. Companies such as JSW, NTPC and PGCIL have already expressed their interests in foraying into electric vehicles and charging stations businesses.
