Over the past few years, metro corporations across India have been gradually shifting to clean energy and have come up with plans to reduce their carbon footprint by adopting renewable energy and other clean energy measures.

According to Mercom’s India Solar Tender Tracker, DMRC has so far issued tenders for 5.2 MW of rooftop solar projects as of December 2020. DMRC has also used other renewable sources to meet its energy needs. Previously, Mercom reported that DMRC had started utilizing power from a 12 MW waste-to-energy project set up by the East Delhi Waste Processing Company in a first-of-its-kind initiative in Gazipur, Uttar Pradesh.

Some of the recent rooftop solar tenders by the Metro Rail Corporation across the country include the 5 MW tender invited by Maharashtra Metro Rail under the RESCO model and the Mumbai Metropolitan Region Development Authority’s 4.43 MW tender for the Mumbai Metro Rail Project’s station site.
