How energy works
From that slice of toast in the morning to switching off the lights at bedtime, our lives run on electricity. It’s easy to not give much thought to how energy works when it’s such a normal part of your life – but imagine getting through the day without it!
A lot needs to happen to make sure electricity gets delivered safely to you. And Western Australia's electricity system is changing fast.
Here’s a behind-the-scenes look at how energy works.
How powerlines work
Once electricity is generated, it is then transmitted to our distribution network (powerlines) to power your home or business.
Substation transformers raise the voltage of the electricity
So it can be transported safely over long distances through the transmission network.
The transmission network then moves the electricity
From the generators to the distribution network.
At the other end, substation transformers lower the voltage
Of the electricity. It's now ready for distribution through the powerlines.
And finally...the distribution network
This is the overhead powerlines and underground cables. They carry the electricity to your home or business.
Decentralised electricity generation in WA
A 'traditional' source like a gas power station, provides a central point for electricity generation. But there are new types of “decentralised” systems changing WA's energy future.
We’re working with our communities to shift our 'traditional' system, towards a renewable energy future. We've joined Synergy and Western Power to support the State Government’s commitment to net zero greenhouse gas emissions by 2030.
That's why we’re exploring a range of decentralised generation such as virtual power plants, microgrids and stand-alone power systems.
Virtual power plants
A VPP is a network of smaller-scale electricity generation and storage sources such as rooftop solar PV systems, batteries and electric vehicles which have been combined.
These smaller electricity sources can be combined and coordinated as a VPP. This way, they can provide the same services to the electricity system as traditional centralised generation.
A VPP can help to balance supply and demand for electricity across the system.
Microgrids
Our service area is about one-quarter of the size of Australia’s land mass. Microgrids are a solution we can use to power remote communities which are not connected to our main grid.
Its technology can include a mix of renewable energy sources, such as solar, wind power and battery storage.
Our customers in Onslow have been part of a world-first energy trial that proved that it's possible to run an energy network on 100% hydrocarbon-free energy without any traditional backup generation.
Moving into the future
As more and more households, businesses and organisations take up solar power, we need to make sure our systems can manage higher levels of renewable energy.
Our electricity systems were originally built for a one-way flow of power when electricity was only generated from a central source. Renewable energy involves a two-way flow of power and can send excess energy back into the network.
We’re working with the State Government and local communities to transition our 'traditional' electricity systems to the future
This includes increasing the amount of solar farms, rooftop solar and battery storage.
Renewable energy is a cleaner way of generating electricity from solar, wind and other renewable sources. But we need to manage the way these sources work to maintain safe and reliable power supply across our networks.
Our unique position in WA
Being separate from the rest of the country, our energy systems have the chance to set an example of how to transition to a cleaner energy future.
We can explore the best ways to move away from relying on fossil fuels to invest in renewable energy and storage, while keeping electricity reliable and affordable.
You might have seen the WA Government has committed to closing the state’s two remaining coal-fired power stations located near Perth by 2030 and ruled out any new gas-fired power stations in the Southwest Interconnected System (SWIS) after 2030.
We’re reducing our reliance on diesel generators
By tapping into more sustainable energy sources like solar, wind, batteries and hydrogen.
We’re also working with local, regional suppliers to further invest in our communities, create local jobs and help build local economies.
By doing this, we can move into a new energy future and create a more sustainable energy supply for our customers.

Restricted Access to Esperance WA EV Network Charger When: Thursday 16th & Friday 17th May 2024 Civil works are being completed around the EV Charging Station in the James St Precinct. Due to these works the charging stations will be unavailable for use during this time. The Temporary Barricade Fencing will be removed Saturday morning to enable access to the facility. You can access a 22kW charger for free at the Horizon Power depot in Esperance, located at Horizon Power, 143 Sims Street.
