What’s involved?

We’re taking a balanced, future-focused approach by supporting more rooftop solar, battery storage, smart EV charging and other technologies that help manage electricity demand, while also planning ahead to ensure enough electricity can be supplied into the region. This includes investigating a new transmission line between Cromwell and Queenstown, alongside the non network solutions that could help meet future demand.

Why is a new transmission line being investigated?

Electricity demand in Queenstown is expected to keep increasing through the 2030s as the population grows and more people switch to electric heating, vehicles and appliances. While solar and batteries will play an important role, they are unlikely to meet future demand on their own. We’ve already made significant upgrades to the existing network, including major improvements at our Frankton substation and Transpower increasing capacity on their current Cromwell–Queenstown transmission line. Even with these improvements, forecasts show additional capacity will be needed in the future to maintain a reliable supply. While the new line is being investigated, we’re also exploring non network solutions that could influence the timing of when the line is required, such as battery storage, optimised EV charging and incentives to shift electricity use.

What happens next?

Large infrastructure projects like this take time to investigate, content, plan and deliver (usually 5-8 years). The current investigation phase will help determine what is needed, where a new line could go, and when it may be required.
