Small Airport, Big Solar Farm – New Plymouth's Renewable Energy Story

A small regional airport. A 15-hectare solar farm. 96% of the electricity going straight to the national grid. This is what commercial ambition meets community purpose looks like.What does it take for a regional airport to become a significant contributor to New Zealand's renewable energy grid? New Plymouth Airport CEO David Scott has a practical answer: vision, commercial discipline, and a willingness to take the harder road.Over the past two and a half years, the airport has developed Te Matakupenga — a 12 megawatt solar farm generating approximately 14,700 megawatt hours annually. The airport uses just 4% — the rest goes to the grid, with a portion sold at a discounted rate to the local council via Ecotricity.This is more than an energy project. It's a story about what's possible when an organisation decides to own the entire process.In this episode, host Nick Morrison talks with David Scott about:How the project evolved from a post-COVID income diversification strategy into something much more meaningfulThe structure of the airport's private power network and how tenants, hangars, and rental car operators all benefitThe Battery Energy Storage System (BESS) coming online in the next few weeks — and what it means for energy resilienceWhy the farm was built at a scale far beyond the airport's own needs, and the commercial logic behind selling to the gridThe partnership with Ecotricity and how the local council is now buying discounted renewable power generated at the airportEV charging infrastructure already powered by the solar farm — and how the airport has future-proofed for electric rental car fleetsThe role of Puketapu Hapū as mana whenua, and how they helped shape the vision and name of the projectThe emissions story — 1,500 tonnes of CO2 equivalent avoided annually, with a carbon payback period of just three and a half to four yearsWhy fixed panels were chosen over rotating ones, and how sheep grazing between the panels solves a land management challengeThe financial payback timeline of seven to ten years — and what future battery storage investments could mean for the bottom lineWhat it would look like for electric aircraft to one day charge from the farm — and why that's closer than you might thinkWhat makes this conversation particularly compelling is David's refreshing honesty. This project started as a commercial decision, and it remains one. But along the way, it became something the whole community can be proud of — a model for how regional infrastructure can lead the way on New Zealand's energy transition.New Plymouth Airport may not be a large organisation, but Te Matakupenga is a large statement about what's possible when you decide to take the harder road.Progress in Practice is a Go Well Consulting series profiling the real-world sustainability initiatives being brought to market by the businesses we work with — the good ideas, the hard work, and the honest lessons learned along the way.To watch this podcast episode and for others, check us out on YouTube here.Click here to find out more about the New Plymouth Airport solar project.To learn more about Go Well Consulting, visit our website here.
