Metro rail transport is becoming a popular means of public transport in India. The Delhi Metro, India's first modern metro caters to more than 25 lakh passengers daily. The metro system in Delhi constructed and operated by the Delhi Metro Rail Corporation Ltd. (DMRC). The network consists of six lines with a total length of 189.63 kilometres (117.83 mi) with 142 stations, of which more than 100 are elevated.

In 2011, GIZ through their project ComSolar entered in a MOU to support DMRC in harnessing solar energy through initial pilot projects and then to scale it up on other metro stations and buildings. Accordingly, three metro sites with different roof types were selected - Dwarka Sector-21 metro station building, Yamuna Bank Depot buildings and Yamuna Bank metro station. Detail feasibility studies were conducted for three sites identifying a potential of 2 MW.

Out of the three sites, the first pilot project of capacity 500 kW is already installed on the roof of Dwarka Sector-21 Metro Station. It was inaugurated by the Union Minister of Urban Development, Sh. M. Venkaiah Naidu in the presence of Union Minister of State for Power, Coal and New & Renewable Energy, Sh. Piyush Goyal as first-of-its-kind plant realised on a RESCO business model. It is built by SunEdison - one of the winners in the bidding organised by Solar Energy Corporation of India (SECI). SunEdison will own, operate the plant and DMRC will purchase electricity from SunEdison through a power purchase agreement (PPA). Comsolar further supported DMRC to replicate similar projects to 10 MW of capacity on other stations and buildings. DMRC has now dedicated a team for implementing solar energy and ComSolar supported in building their internal capacities.

GIZ in partnership with Delhi Metro Rail Corporation Limited (DMRC), the Institution of Engineering and Technology (IET UK) and lnstitution of Railway Electrical Engineers (IREE) organized a one day workshop and exhibition on 10th January 2015 in New Delhi to promote solar energy in metro and rail transport sector. The event was an initiative to highlight the potential of solar energy in the transport sector. It also aimed to inspire the participating organizations to learn from success of implementing solar energy in DMRC stations and buildings. 

DMRC aims to implement solar photovoltaic plants with a cumulative capacity of 50 MW by 2017 on the roof of the stations, depots and other office buildings. In the long term, DMRC is also looking forward to procure 500 MW of power from a large scale ground mounted solar power plant in Rajasthan.
