Delhi Metro goes green with solar power

Delhi Metro is turning more eco-friendly with installation of solar panels for electricity at its headquarters which will prevent 2.35 tonnes of greenhouse gas emissions per year.

The 64 panel five kilowatt (KW) solar power plant installed at the Metro Headquarters in Connaught Place can generate 15 Kilowatt hour (KWh) electricity per day, Delhi Metro spokesperson Anuj Dayal said.

This will result in preventing 2.35 tonnes of greenhouse gas (GHG) emissions per year by the Delhi Metro, recently registered by the United Nations as the first Railway project in the world to earn carbon credits.

The solar power plant presently caters to the need of lighting electrical equipments including the terrace lightings at the Metro Bhawan from dusk to dawn.

Installed at a cost of around Rs 20 lakh on an experimental basis, the five KWp Solar Photovoltaic (PV) power plant includes the crystalline silicon solar PV modules (5 Kilowatt), a maintenance-free Battery Bank of 1000 Ah capacity, Charge Controller and an Inverter.

The Delhi Metro also plans to use solar energy for IT Park and LED street lightings along Patel Chowk and Chandni Chowk Metro stations, the official said.

The system has been designed for providing uninterrupted operation of the specified loads for a period of three consecutive sunless days.

Delhi Metro fights against global warming

The Delhi Metro, the first railway project in the world to be registered for carbon credits by the United Nations, have received a UN certificate for preventing over 90,000 tonnes of carbon dioxide from being released into the atmosphere by reducing its power requirement, thus contributing to the fight against global warming.

The certification report was given by Germany-based validation organisation TUV NORD which conducted an audit on behalf of United Nations Framework Convention on Climate Change (UNFCCC), a DMRC release said. The DMRC was found to have restrictesd the emission of 90,004 tonnes of carbon dioxide from 2004 to 2007 by adoption of regenerative braking systems in the Delhi Metro trains.

Under this regenerative braking process for which DMRC earned carbon credits, whenever trains on the Metro network apply brakes, three phase-traction motors installed on these trains act as generators to produce electrical energy which goes back into the Over Head Electricity (OHE) lines. The regenerated electrical energy that is supplied back to the OHE is used by other accelerating trains in the same service line, thus saving overall energy in the system as about 30 per cent of electricity requirement is reduced.

The DMRC also claims to have saved 1,12,500 megawatt hours of power by restricting and reusing power on its trains through regenerative braking, thus saving the emission of 90,004 tonnes of carbon dioxide into the atmosphere from 2004 to 2007. It is estimated that in 2008, release of 39,000 tonnes of CO2 was prevented and this figure will increase to over 100,000 tonnes per year once Phase-II of the Metro project is fully operational.

Delhi Metro gets UN certificate for preventing carbon emission

NEW DELHI: Adding yet another feather to its cap, Delhi Metro has become the first rail network in the world to get a UN certificate for preventing over 90,000 tonnes of carbon dioxide from being released into the atmosphere, doing its bit to fight against global warming.

The certification report, given by Germany-based validation organisation TUV NORD which conducted an audit on behalf of the UN Framework Convention on Climate Change Change (UNFCCC), found that the DMRC stopped the emission of 90,004 tonnes of carbon dioxide from 2004 to 2007 by adopting regenerative braking systems in the metro trains.

“The UN certificate was given to the DMRC for preventing over 90,000 tonnes of carbon dioxide from being released into the atmosphere by deducing its power requirement, thus contributing to the fight against global warming,” Delhi Metro spokesperson Anuj Dayal said today.

Under regenerative braking process for which DMRC earned carbon credits, whenever trains on the Metro network apply brakes, three phase-traction motors installed on them act as generators to produce electrical energy which goes back into the Over head Electricity (OHE) lines.

The regenerated energy that is supplied back to the OHE is used by other accelerating trains in the same service line, thus saving overall energy in the system as about 30 per cent of electricity requirement is reduced.
