In a move to make its operations more sustainable and reap some overhead savings, Hawke’s Bay Airport is investing in a rooftop solar system to be installed in the next few months.
The new system will help us better manage our energy costs, says Hawke’s Bay Airport CEO Nick Flack.
“Currently, electricity consumption in the terminal is 86% of our total electricity usage. With energy prices high, it makes sense to make the most of our significant roof area and Hawke’s Bay’s beautiful weather to reduce our costs. Our new system will go a long way help us do that, as well as support our net zero carbon aspiration.”
The airport’s rooftop solar system will be one of the largest rooftop solar arrays in Napier, and is a solar plus battery solution. Six hundred and fifteen solar panels will produce 477,171 kWh per annum, equivalent to 44% of the airport’s annual terminal demand.
Including batteries allows the airport to be smarter about how it uses electricity, says Nick Flack.
“It’s not necessarily about storing to sell back to the grid, but rather taking electricity from the grid at times of the day when it is cheaper, storing it, and then and using that stored energy at peak times when electricity is more expensive.
“Our system uses AI to predict the most cost effective energy source (grid, solar, battery) to optimise energy management. Sustainability is at the heart of everything we do, so to be able to have this intelligence built into the system is a fantastic addition to our sustainability story,” says Mr Flack.
After a competitive tender process, the contract to supply the new solar system was awarded to Ecoefficient, a local Hawke’s Bay business. The new solar system has a pay-back period of just over five years, and an estimated life of 30 years. It will also support Hawke’s Bay Airport’s renewal of its Level 4+ airport carbon accreditation early next year.
Laura Andrews, Co-Founder of Ecoefficient Solutions NZ, says this project is a statement about the future of Hawke’s Bay.
“It demonstrates how commercial sites can take bold, practical steps toward energy independence and carbon reduction, while securing long-term cost savings. We’re proud to deliver one of Hawke’s Bay’s largest rooftop solar and battery installations, setting a benchmark for sustainable leadership in our region.”
In addition to the solar system install, the airport undertook an energy audit to identify quick wins in the bid to improve terminal comfort, and to optimise terminal energy systems such as air conditioning and lighting.
