Mount Hopeful Battery Overview
The Mount Hopeful Battery is a proposed grid-scale energy storage project in Central Queensland and forms a key part of the broader Mount Hopeful Wind Farm and Battery Project.
The battery will be located on the eastern side of the wind farm site, along South Ulam Road.
With a planned capacity of up to 600 MW and up to four hours of stored energy, the battery will enhance the delivery of clean, reliable electricity to the National Electricity Market, while supporting grid stability and flexibility.
Significant cost savings for consumers
Aurecon undertook independent reviews of Neoen’s Hornsdale Power Reserve Big Battery performance in South Australia in 2018 and 2019. The studies showed how the project supports the National Electricity Market (NEM) and delivers savings to all electricity consumers.
In 2019 the battery reduced electricity costs by $116M through the provision of Frequency Control Ancillary Services (FCAS). Thanks to HPR, average Regulation FCAS costs have been reduced by more than 90% meaning major savings for all South Australian energy consumers.
Basic Function
When there is excess energy, the battery will charge. When there is high demand for energy, the battery will discharge.
Frequency support
To maintain the stability of the system, the grid has frequency control. The battery discharges electricity in response to frequency changes. The battery will also add competition to the market which helps reduce consumer electricity prices, helping to reduce electricity costs.
Virtual Inertia
As with vehicle suspension on an uneven road, inertia services are essential for stabilising the grid. A big battery can enable the advanced power inverters to emulate the existing inertia services being supplied by an ageing fleet of fossil fuel power plants. This service is currently being trialled at Hornsdale Power Reserve.
Network support
Grid-scale batteries can provide dynamic warp-speed responses so existing transmission lines can operate at full capacity. Like adding another lane to a freeway, the battery can unlock additional capacity on existing transmission networks – saving customers millions of dollars in expensive transmission line upgrades.
Firming renewables
Along with wind and solar technologies, large-scale batteries help to firm variable renewable energy. Batteries are an essential component in the stable transition to clean electricity and achieving emissions reduction targets.
Big Battery Expertise
Neoen are leading the way in delivering big batteries in Australia and around the world.
Neoen’s 150 MW Hornsdale Power Reserve, more commonly as the ‘Tesla Big Battery’, has been keeping the lights on and electricity costs low for South Australians, since 2017.
Our 560 MW Collie Battery, currently in operation near Collie in Western Australia, is one of the world’s largest batteries.
