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.
