A solar farm big enough to power 20 percent of residential Christchurch is to be built at the city's airport. 

Kowhai Park is 400 hectares of land at Christchurch Airport that will be used to generate renewable energy. 

Phase one will deliver a 220-hectare solar array capable of generating 150 megawatts of electricity, enough to power 30,000 homes, on the airport campus. 

Australian renewable energy fund, Solar Bay, is committing $100 million to the development of Phase One. They say there is nothing else like this in New Zealand; it’s innovative, far ahead of its time and absolutely world leading in every sense. 

Solar Bay co-founder Andrew Archibald joined Kerre McIvor.
