A new power station

A new, more efficient power station will be constructed, reducing the carbon footprint of power supply to Esperance by almost 50% per annum compared to the existing power supply arrangements.

This includes a battery energy storage system which will improve the efficiency of the power station by responding to variabilities in power transmission. This will also help reduce the likelihood of power fluctuations.

A new renewables hub

A new renewables hub will be constructed, bringing together solar and wind power to generate up to 46% of Esperance’s electricity.

Wind turbines: will continue to be an important part of Esperance’s energy mix with the construction of two new state-of-the-art 4.3 megawatt wind turbines.
Improvements in design and technology mean the new turbines will have more power and higher capacity, producing 58% more wind power than the combined output of the current 6 wind turbines.

Solar farm: the construction of a new 4 megawatt solar farm comprising of more than 10,000 solar panels will make it the largest solar farm in Horizon Power’s renewables portfolio to date.
Solar and wind power are complementary renewable energy sources. During the day the solar farm is capturing the energy from the sun, and after dark is when the wind farm is most active.

Combined, these two energy sources will enable electricity to be generated by renewables on a 24 / 7 basis.

What are the benefits of the new power solution?
Esperance’s future power solution is combining a new, more efficient power station with a significant increase in renewables.
This is a long term solution which will deliver cleaner electricity by reducing the carbon footprint and increasing the generation of renewable energy to provide the best outcome for the community.

Will the new power station have lower carbon emissions?
Yes.  Through improved design and technology, a more efficient power station will be constructed. This new power station will deliver a 50 per cent reduction in carbon emissions per annum compared to the existing power supply arrangements.

This significant reduction in carbon emissions is the equivalent to removing approximately 6,458 cars off the road annually.  
That’s almost the equivalent of the total number of registered motor vehicles in Esperance.

How much of Esperance’s electricity will be generated by renewables?
A new state-of-the-art renewables hub will be constructed to deliver approximately double the annual amount of renewable energy being produced by the current power solution.

The hub will includes a new 4 megawatt solar farm and two 4.3 megawatt wind turbines.  Combined, this will deliver up to 46% of Esperance’s renewable energy annually.

Where will the new renewables hub be located?
The new renewables hub comprising of a 4 megawatt solar farm and two 4.3 megawatt wind turbines will be constructed in the Shark Lake industrial area.

This will create an iconic landmark for Esperance, which air passengers travelling into and out of Esperance airport will be able to view.

How large is the new solar farm?
A new 4 megawatt solar farm comprising of more than 10,000 solar panels will be constructed.

This will be the largest solar farm in Horizon Power’s renewables portfolio to date.

Why are you combining wind turbines and solar power?
Horizon Power has been leading the way in developing tailored large and small scale renewable solutions throughout regional WA.  Over the past decade, we have been progressively incorporating more renewables, in particular solar energy, into our portfolio.

Solar and wind power are complementary renewable energy sources and together are ideal for Esperance’s weather conditions.

During the day the solar farm is capturing the energy from the sun, and after dark is when the wind farm is most active.

Combined, these two energy sources will enable electricity to be generated by renewables on a 24 / 7 basis.

Will the current wind turbines be used?
Wind turbines will continue to be an important part of Esperance’s energy mix.

Two new state-of-the-art wind turbines will be constructed to replace the existing, aging wind turbines.

Through improvements in design and technology these new turbines will be able to make more efficient use of the wind resources in Esperance, and have more power and a higher capacity to produce electricity.Each wind turbine will stand more than 100 metres high and combined will have the capability to generate 8.6 megawatts of power. 

That’s 58% more wind power than the combined output of the existing 6 turbines.

Will the wind turbines be located on the existing site?
The wind turbines located on Nine Mile Beach are operated by Synergy.

Horizon Power ran an open procurement process, and Synergy did not engage with Horizon Power as part of this process.

Horizon Power acknowledges the community’s connection to the Nine Mile Beach site and would have welcomed the opportunity to engage with Synergy on how it might have delivered a future energy solution which incorporated the current location.

Will there be an opportunity for the community to become involved in the renewables hub?
Yes. Horizon Power recognises the Esperance community’s strong support for renewable energy. The inclusion the new renewables hub will have the capability to generate up to 46% of the community’s annual power through renewables, and presents an exciting opportunity for Horizon Power to involve the community in exploring an interest in, and the possibility of, a future shared ownership of the solar farm.

As the project progresses, this is an opportunity which Horizon Power will further explore with the community through a comprehensive engagement process.
