NOIDA: Noida Metro corridor is going to be India’s greenest metro once it becomes operational as it will have the capacity to generate enough of solar power to operate not just 21 stations en route but also the train and the offices.The 29.7 km metro corridor is scheduled to start within the period of about one year and it will have the production capacity to generate enough of renewable energy to make it a self-dependent corridor.
Noida Metro will stand out as India’s most environment-friendly Metro project because the entire corridor will homogenously use solar power, right from its head office to parking lots and footbridges, though the practices being followed are similar to those Delhi Metro is employing in Phase-3 and some of its existing stations.
Noida Metro has set a target of generating 12MW of solar power daily, its managing director Santosh Yadav said on Tuesday. For the yield, it has started the installation solar panels around the rooftops of stations, footbridges, its main office building, the parking and depot lot boundary walls. “We are going to also obtain a diamond rating for the buildings by the Indian Green Building Council (IGBC),” Yadav said. “Metro’s total power consumption can be reduced further with better engineering practices, sleek design, recycle and reuse,” Yadav said solar energy will run fans, air, escalators, elevators and lights-conditioning systems at its offices and stations. If required or as a backup if there is a glitch, officials said, the conventional power connection will be used as a supplementary source.
Metro officials estimate the corridor’s total power consumption, excluding the electricity needed to run the trains and some other crucial operational facilities, is going to be under the 12 MW solar energy the corridor collectively generates. If there is a surplus, Metro will route it to the conventional power grid and claim a rebate on its power usage, cutting operational costs.
“Each one of the stations will be powered by its very own green energy. Rooftops of stations will have solar panels installedand the buildings will fit with LED bulbs. The two sub-stations that will supply power for trains running on the corridor may also support solar power panels,” Yadav said.
The corridor, which is being built by DMRC, can also be recycling construction waste. “Wasted concrete is being utilized to make kerbstones and tiles, which will be used at stations. We are also using wasted iron for grilles and railings of stations,” Yadav said. “We have been using fly ash in construction, preserving the top soil. The water used in our train depot will be 100% recycled. It will likely be a zero-discharge facility,” he added.
Noida Metro Railway Corporation’s headquarters in Sector 29 would be the first building in the NCR city to completely generate solar power for its own consumption. “We are going to generate about 30 kW electricity for the building,” Yadav said. The project’s environmental initiatives have been taken up under the terms of reference issued by the State-level Environment Impact Assessment Authority (SEIAA), which it approached after a direction from the National Green Tribunal (NGT) to obtain environmental clearance.
Under those guidelines, Noida Metro must also build sound barriers along the entire line, 576 rainwater harvesting pits and plant nearly 18,000 trees to compensate for the loss of greenery because of construction.
