Join the System Operator in Wellington, Auckland, Hamilton or Christchurch
Perform power studies and analysis to support generator connections
Validate dynamic models of generation connecting to the power system
Our core purpose is to empower the energy future for New Zealand - a future that delivers a net-zero carbon economy and a reliable and secure electricity system.
At the heart of ensuring security of our 24/7 power supply is the System Operator who operates the wholesale electricity market and manages power system security now and into the future. Our Power Systems group is responsible for providing a service of power system analysis and engineering, risk and assurance management to enable Transpower in its role as System Operator to meet principal performance obligations.

About the team
Our Power Systems Engineering team, along with both Power Systems Development and Engineering Assurance teams in the System Operator, work closely with electricity industry participants to understand how their assets perform against their obligations, as well as studying and understanding existing and future power system risks and technologies.
In doing so the teams ensure our National Coordination Centre (balancing power supply and demand in real time), and the wider System Operator teams have access to the right information, models and engineering support for operating the electricity market and power system.
Our Power Systems Engineering team are experts in power system modelling and analysis and support the Engineering Assurance (Commissioning) Team, by reviewing power system connection studies provided by Asset Owners and Generators. They review risks and impacts to the System Operator as a result of connection, to ensure compliance to the electricity industry participation code.
They also produce industry information including the following

The Opportunity - energise your career at the heart of the electricity sector!
If you love power systems analysis and have a passion for renewable energy, working in the System Operator will give you the opportunity to collaborate with subject matter experts and enjoy stimulating, meaningful work including conducting or assessing:
Generator Connection and System Impact studies
Exploring the impacts of Inverter Based Resources and Battery Energy Storage
Compliance Assessment Studies
You'll explore and communicate the challenges and opportunities that the transition to a 100% renewable electricity system will bring. You'll also be involved in engaging with the Electricity Authority, and industry participants to enable a secure and resilient power system for generations to come.
What will you bring?
Experience in time domain simulations, dynamic modelling, and analysing operational challenges of integrating renewable generation.
You may have worked for a Transmission System Operator, Grid Owner or Engineering Consultancy, modelling and analysing complex power systems but whatever your background, you'll enjoy working both autonomously, and as part of a team, with as you consider the implications of system stability, and system security to power system operations.
To be considered, your CV and cover letter will demonstrate:
A minimum of a bachelor's degree in electrical engineering, or related field with Power Systems papers
~7 or more years leading power system studies
Proven experience with preparing/validating power flow cases and dynamic models in PowerFactory for conducting power system analysis and simulations. Where applicable, please share reports you have been involved with.
Working knowledge of power system analysis tools to support building dynamic power system models and performing load flow and time domain simulations; ideally in DIgSILENT PowerFactory (or Siemens PSS®E). DSA Tools or PSCAD are a bonus!
Demonstrated ability to analyse and interpret complex problems or processes, identify and understand requirements and develop alternatives.
Well-developed verbal and written communication skills to concisely convey complex technical information and grow the power system modelling and analysis/engineering capability of others
