It might seem strange to be celebrating an airport given the aviation sector is still so reliant on fossil fuels, but the Rewiring philosophy is to electrify what you can and make the right decision when the time comes. There are not many, if any, electric equivalents available when it comes to planes, but there's plenty more that can be done in other areas.

One of the airport's biggest initiatives is the Kōwhai Park solar farm, which is located beside the airport. With around 300,000 panels, Boswell says it will be the biggest in the country and could power 30-40,000 homes. This is just phase one and it has the ability to replicate that two or three times over.

The solar farm will be providing power to the grid (and also helping to irrigate the Canterbury Plains in summer when solar production is high) but it will also provide a chunk of that generation to the airport. Part of the rationale for the deal was that it helped the airport avoid a significant cost that would have been required for an upgrade as it reached the limits of its connection.  

While Gary Freedman's Electric Air plane, the Pipistrel Alpha Electro, can often be spotted at the airport, Air New Zealand is currently trialling an electric plane and the innovation continues in this space. Boswell thinks the next generation of domestic turboprop planes will be battery and sustainable aviation fuel hybrids.

There are now a number of electric ground support vehicles at the airport, from tugs to the country’s first electric fire engine. And it also has a number of electric fleet vehicles and chargers.
