The Kempegowda International Airport here has achieved net energy neutral status in the Financial Year 2020-21 as part of its sustainability goals. Bengaluru international airport (BIAL) has been able to save nearly 22 lakh units of energy in the Financial Year 2020-21, enough to power nearly 9,000 houses for a month.
According to BIAL, these measures were achieved through solar installation at rooftops of utility buildings, car parks, ground-mounted solar installation at the airside, rooftops of cargo buildings and project offices. It has also begun purchasing 40 million units of solar power through open access and wind power purchase through open access. Adoption of LED and optimal use of natural light contributed to energy-neutral status.
