India’s first super-fast bullet train, which will connect Mumbai and Ahmedabad, will consume 40% more electricity than what the entire Delhi Metro network requires, according to an estimate by the National High Speed Rail Corporation Limited (NHSRCL), which is executing the project.
NHSRCL said the project, once operational, will require 1,100 million units of electricity per year to power the train and the stations it will stop at. In comparison, Delhi Metro, which runs on eight lines spanning 350 kilometres serving 236 stations and connects the capital with satellite towns like Gurugram and Noida, consumes 850 million units per annum.
Officials said this difference in consumption is because bullet trains need to attain a certain speed — much higher than what a metro train is capable of — and because metro trains deploy regenerative braking, a technology that recovers some energy while stopping and converts it back into usable electricity.
