As many as 21 railway buildings, including key installations in Mumbai, have been awarded the prestigious ‘Shunya’ label by the Bureau of Electrical Energy for achieving energy self-sufficiency.

These buildings generate their own electricity, primarily through solar power, meeting their annual energy needs without relying on external supply. In the list are two Mumbai-based facilities, including local train POH (Periodical Overhauling) workshop and Sanpada carshed, with surplus power generation enabling them to supply electricity to other railway installations. This puts them in the ‘Shunya+’ category.
