The team is currently progressing several major capital projects and regional plans to increase transmission capacity into Auckland, Waikato, Canterbury, Tauranga, and Queenstown. The team also works on new connection projects to seamlessly integrate generation and load into the power system.
About The Opportunity
Based in Wellington or Auckland, you'll lead complex generation connection studies and play a key role in shaping the future of New Zealand's transmission grid: championing the ongoing development of Transpower's connection study processes as Grid Owner.

You'll gain exposure to some of the most interesting and high-impact challenges in the sector! From integrating offshore wind and large-scale data centres to supporting decarbonisation through future-focused planning, you'll bring your technical expertise and commercial awareness to deliver robust, strategic outcomes.
You'll work across teams and with external partners, translating technical ideas for a wide range of audiences, including project teams, regulators, industry groups, and service providers.
About You
You're inquisitive and collaborative, with the ability to lead technical workstreams while engaging across disciplines. You enjoy solving novel, system-level problems, feel energized when working with others to get results, and take pride in mentoring and developing team members.
To be considered for this role, your career to date, cover letter, and CV should clearly demonstrate:
