The Delhi Metro Rail Corporation (DMRC) has made preparations to generate approximately one crore units of electricity from sunlight on the Metro Phase-IV corridor under construction. Metro will receive approximately 10 MW of additional solar energy from all three corridors. There is currently about 47 MW of solar energy being generated in the metro network within Delhi-NCR. It will be used by Metro itself. At the same time, network expansion in 2031 will save 573 million hours per year. This allows thousands of passengers to make good use of the time wasted in traffic jams on the road.

Construction is underway within a 40-mile radius of the three corridors of Phase IV of the Delhi Metro. About 33% of construction has been completed on RK Ashram-Janakpuri (West), Tughlakabad-Aerocity and Maujpur-Majlis Park corridors. By 2025, metro services will also start on the phase IV corridor. Solar equipment and installations will be installed on rooftops, parking lots and sheds, including subway stations, to capture solar energy.

In the year 2014, DMRC took a step towards renewable energy with 500 KW solar power in Dwarka Sector-21 for solar power. Currently, out of 115 station complexes in Delhi, 37 are getting solar power equipment while Noida is getting 10 MW. With the generation of additional 10 MW of solar energy in metro stations on all three corridors of Metro Phase-IV, Delhi Metro will reach 60 MW productive. Solar energy covers 35% of the total power consumption for Metro operations and meets the needs of stations.

Energy production also increases due to the Resco model

Under the Renewable Energy Service Company (RESCO) model, solar power stations have been installed on the roofs of government buildings. On this basis, the initiative office does not receive a subsidy, but it also does not have to spend anything on solar installations on the roofs of the metro and parking.

Earned millions of rupees from 35.5 lakh carbon credits in six years

Delhi Metro is the first such service in the world, which also earns the carbon credits earned by reducing greenhouse gas emissions. Four of his projects are registered with the United Nations Framework Convention on Climate Change (UNFCC). This includes activities related to solar energy projects apart from regenerative braking. Under the Kyoto Protocol, it allows the public and private sectors in countries to purchase carbon credits from projects that reduce greenhouse gas emissions. DMRC has earned an income of Rs 19.5 crore for the past six years from the sale of 35.5 lakh carbon credits by investing in Clean Development Mechanism projects.

Metro will reduce lakhs of vehicles from the roads

According to a study by Tata Energy Research Institute (TERI), clean energy initiatives and metro network expansion will reduce five lakh vehicles per day off the road by the year 2021. This also saves 2.55 lakh tons of fuel spent on private vehicles. Metro services will also reduce carbon emissions by 7.66 lakh tons annually. To date, more than 5,35,150 saplings have been planted by DMRC. In this, along with the lack of oxygen in the environment, it also helps in reducing pollution.

kinetic energy is stored

In regenerative braking, the kinetic energy generated by braking is stored rather than dissipated to reduce the speed of the subway. It will be used later according to the requirement. This reduces dependence on other sources to meet energy needs. Other devices, including batteries, compressed gas, and supercapacitors, are used to store energy. Regenerative braking increases the overall energy efficiency of the subway. For example, the service life of the system is also longer with the brakes.

sources of solar energy
