Alice Springs Airport nears 100% renewables with new solar array

Alice Springs Airport will soon have one of the largest airport solar systems in Australia, with plans to install more than 1000 PV panels on the roof of a shaded long-term parking bay.

The $1.9 million project will add to the Airport’s award-winning solar energy station, and will boost its total solar capacity to 800kW and its self-generation capacity by around 40 per cent – it currently gets more than half its power needs from the existing solar energy stations on site.

Construction of the project will begin next month, marking the third stage of the Airport’s long-term strategy to boost the sustainability of the its operations.

Local company Sitzler Bros has been appointed as contractor for the project and will continue the work it started with the existing solar shade structures, constructed in 2014. The rooftop solar array is expected to be completed in late 2015.

“Our solar power projects have been hugely successful for the business,” said airport general manager Dave Batic. “We’re committed to further developing our solar energy capabilities, especially when it comes to thinking outside the square to make it happen.

“This latest phase will turn our entire long term car park into a solar energy station, and when it’s complete will offset the equivalent of 430 tonnes of carbon dioxide emissions per year. The combined total of our solar power output, more than 800kw, will offset a massive 1270 tonnes of annual carbon dioxide emissions.

“ASP was the first Australian airport to see the benefits of investing in large scale PV technology that feeds back to our grid,” said Dave. “Now with a system large enough to power 280 homes for a year we believe it’s one of the biggest airport solar stations in the country as well.”

In 2014, ASP was named Major Airport of the Year by the Australian Airports Association (AAA) for its investment into solar power infrastructure. The solar energy project also won the Safe Climate Award at the Environment Centre NT’s inaugural Ochre Green awards, which recognise outstanding efforts and outcomes by Territorians for the environment.

    That’s about $6 a watt. I wonder what the average cost of rooftop solar in Alice Springs is? They may have gotten more bang for their buck if they spread it out on roofs across Alice Springs. Pay to put a system of the roofs of people who want them, give them a discount on their bills, and the airport uses the solar electricity generated through the existing grid. I’m all for creative accounting if it results in greater reduced emissions and is honest creative accounting.

    I realize that pretty much everything costs more in Alice Springs due to its isolation, but I suspect new rooftop solar averages under $6 a watt.

      I wonder how much it would cost for a traditional shade structure as well.

        Quite a lot, I would imagine. The introductory paragraph says, “…plans to install more than 1000 PV panels on the roof of a shaded long-term parking bay.” which made it seem like the shaded long-term parking bay already existed to me. However, when I look down at Alice Springs Airport from above – like a god! I see no sign of any shaded parking. Note however, there is a slight delay of a year or so on my god vision, so the solar shades the article mentions were built in 2014 could definitely be there. So it certainly seems like the shading is new. Then there’s potentially the cost of surfacing the carpark. And the fence in the mock up photo dosen’t seem to exist and they are really expensive to build. So expensive it makes me wonder why they didn’t put the solar panels of the roof of the airport where they wouldn’t need a fence, but maybe kangaroos can jump that high around Alice and frequently bound across the airport roof.

        Mind you, if the close to $6 a watt is just for the solar shades, and nothing else, since the shades aren’t too different from fixed utility scale solar panels with longer legs and presumably the ability to handle more wind loading, and fixed PV can installed for under $2 a watt in foreign type places, there should still be room for considerable price decreases in solar carpark shading – although I’m not suggesting it is likely to get as cheap as just sticking stumpy legged PV in a field somewhere.

    @Ronald B: Ever thought that long term car parking might imply security fence? That fence is where it is for a reason.

      No I have never thought that in my life. But now that you mention it, perhaps it is something I should consider. Deeply.
