Project overview
We’re delivering a long-term energy solution for Leonora that will provide secure, reliable and affordable power for the community, now and into the future.
Through a Power Purchase Agreement, we will replace ageing generation infrastructure with a modernised power station, supporting growing electricity demand and enabling increased uptake of customer energy resources.

Driving lower emissions
How does Leonora's current system work?
Leonora’s current power supply is primarily generated from diesel and natural gas, with limited renewable energy penetration.
The existing power station includes diesel generation assets that have reached end of life. At the same time, electricity demand has increased, with summer peak loads exceeding reliable capacity.
Prolonged heat events have placed additional strain on ageing equipment, contributing to outages across the town.
Replacing this infrastructure will improve reliability and support future growth.
Community engagement
Communities are at the heart of our Power Projects, which work to ensure active participation among all stakeholders, including residents, Traditional Owners, businesses, and community groups throughout the process.
We consider community aspirations, existing infrastructure, and factors like land, heritage, and the environment to align planning with Leonora's unique characteristics. Our approach includes informing, consulting, incorporating input, and communicating back to the community.
What's happening now?
We’re progressing delivery of a new power station for Leonora. Construction is planned to commence in late 2026 and be completed by early 2027, with first power from the new system expected later that year.
We’ll continue to share updates and consult the community as the project progresses.
What does this mean for the community?
Supporting future growth
The new system will meet increasing electricity demand across the community.

Ensuring we develop long-term solutions aligned with the unique characteristics and interests of the community.
What's happening and when?
Here's a high level timeline of what to expect, subject to change as the project progresses.
Ensuring a secure, reliable and affordable power supply is our priority.
Leonora's existing power station includes diesel generation assets that have reached end of life. At the same time, electricity demand has increased, with summer peak loads exceeding reliable capacity. Prolonged heat events have placed additional strain on ageing equipment, contributing to outages across the town.
Replacing this infrastructure now will improve reliability, support future growth and enable increased uptake of customer energy resources such as rooftop solar and batteries.
Leonora already has some rooftop solar installed across homes and businesses.
We’re continuing to support the safe integration of customer energy resources, including rooftop solar and batteries, to help increase renewable energy participation over time.
The project will improve the reliability of your electricity supply by replacing ageing infrastructure.
It will also support future growth in the town and enable more customers to install rooftop solar and other energy technologies.
The project will deliver a modernised power station to ensure reliable supply.
It is designed to support increased uptake of customer energy resources, such as rooftop solar and batteries, which will play an important role in Leonora’s energy future.
Thermal generation will continue to support reliability, particularly during peak demand and low renewable generation.
The new power station will be built on the existing power station site.
Horizon Power may also consider land for future renewable energy development; however, current efforts are focused on delivering the new power station and supporting customer energy resources such as rooftop solar and batteries.
Horizon Power acknowledges the Traditional Custodians throughout Western Australia and their continuing connection to the land, waters and community. We pay our respects to all members of the Aboriginal communities and their cultures; and to Elders past, present and emerging.
