A 15 MW solar power plant, having a project cost of Rs 8.8 million, is under trial at Kolkata airport. It will be connected to the Calcutta Electric Supply Corporation grid through the net metering arrangement. Spread over an area of 65 acres to the east of the primary runway, the plant consists of 5,454 solar panels each having a capacity of 330 watt. The solar power plant is expected to generate 1.3 million units of electricity a month sufficient to electrify approximately 1,000, homes. In addition, the power plant will bring down the airport’s monthly electricity bill from Rs 600,000 to Rs 475,000, resulting in annual savings of Rs 1.5 million.
