Brisbane Airport Corporation (BAC) has announced it is investing in a major renewable energy Solar PV project capable of generating more than 9,315,000 kilowatt hours a year.
The 6MW system, consisting of 22,000 panels spanning an area of 387,500sq ft (36,000m²) will be installed across six sites at Brisbane Airport (IATA: BNE).
Brisbane Airport’s International Terminal alone will support 1.98MW with 7,133 panels covering more than 125,668sq ft (11,675m²) square metres, making it the largest single roof top solar panel installation at an Australian airport and BNE and the largest commercial roof top solar system in the Southern Hemisphere.
Krishan Tangri, BAC General Manager Assets, said electricity is one of the biggest expenses to running Brisbane Airport with dozens of large buildings requiring cool, lighting and heating 24 hours a days, 365 days a year.
“We are acutely aware of the increasing energy needs of running a major airport and since 2012 we’ve had an extensive energy reduction program in place resulting in the completion of 40 projects which collectively save more than 8 GWh per year.
“We are in the enviable position of having thousands of square metres of un-impeded roof space ideal for solar harvesting and, with systems becoming more efficient and more affordable to install, it makes financial sense to invest in this readily available supply of renewable energy to save costs and decrease our carbon footprint.
“Once fully operational, the new system will account for 18% of BAC’s direct electricity consumption, or 6% of our total consumption, further complementing the savings we’re making through air conditioning control optimisation, lighting control upgrades and LED technology within BAC buildings, car parks and street lighting,” Mr Tangri said.
The airport says the solar energy generated per year is equivalent to powering over 1,700 homes for a year, with carbon offset equal to planting over 50,000 trees or taking 1,500 cars off the road each year.
Design of the system is currently underway with installation commencing from December 2017 and completion expected in August 2018.
