Our people

We work and live in the regions we serve - and we recognise we have a special responsibility to the people of WA. We are on a mission to create regional employment opportunities and foster a workplace where our people’s stories, backgrounds, abilities and differences are celebrated.

Being part of our teams creates unique opportunities for our people to learn and develop in a range of trades, professions, skills and experiences.

Whether it's in our Perth office, in one of the regional depots or out in the field - there are dedicated teams throughout the communities working to provide safe, more sustainable and affordable energy solutions across 38 microgrids.

The diverse roles and responsibilities are extensive and include some of the following areas:

Shaping the energy systems of the future

Our Integrated Resoource Planning and Major Projects teams are testing and exploring the future... today. Combining data, innovation, technology and community engagement - they're cocreating the next generation of energy solutions to support regional WA including Hydrogen, Net Zero towns and Standalone Power Systems powers.

Supporting our customers and communities

Embedded in our regions, the interests of our customers is at the heart of everything we do.

Whether it's helping them to manage their energy or reduce their bills, supporting their local community organisations or designing innovative solutions to deliver greener, more affordable energy - there's a great range of roles and teams leading our transition to a customer-centric organisation.  

On the ground delivering safe and reliable energy

The field crews are out in the regions building, maintaining and replacing our energy system assets across 38 microdgrids.

Our diverse range of operational roles from structural, civil and renewable engineers to electrical tradespeople, field trainers, electrical technicians, cable jointers and lineworkers.

Accelerating our digital transformation

The future of energy is evolving fast - as customer demand and new technologies drive the need for better, greener solutions. That's why it's such an exciting time to be part of the digital teams - as we accelerate and broadern our digital capabilities to keep pace with a rapidly evolving industry.

The use of innovative technologies such as process automation, big data, artificial intelligence, machine learning, the Internet of Things (IoT) and the Cloud underpin our transition towards decentralised and decarbonised microgrids.

Our day-to-day operations are managed by our Chief Executive Officer and executive management team. Their number one priority remains the safety and wellbeing of our people and the communities we serve.
