New battery energy storage system proposed for Stanwell near Rockhampton

Plans have been lodged with Rockhampton Regional Council for the proposed new project near Rockhampton. See the details here.

‘Reliable’ energy should be the ‘priority’

A new Central Queensland project is expected to play an “increasingly important role” in the future of the energy market, as well as create dozens of new jobs if it gets the green light from council.

A material change of use application was recently lodged with Rockhampton Regional Council on behalf of Stanwell Corporation, which owns and operates the Stanwell and Tarong coal-fired power stations, for a new 150 MW battery energy storage system.

According to the report, the BESS would be located near the Stanwell Power Station and would be built in two stages.

Stage one would involve the installation of batteries with an output of 150 MW/300 MWh and stage two would have an output of up to 1,300 MW/2,600 MWh.

The project site would be about 12 hectares in size.

“It is anticipated the Project will utilise lithium-ion battery technology for Stage One while Stage Two may use lithium-ion or flow battery technology,” the report says.

“Batteries used in the BESS will be of identical make, model, voltage, power output and storage capacity and will be rack-mounted and housed in airconditioned/thermally managed weatherproof enclosures.”

The batteries would not be electrically connected directly to the power station, but would be connected directly into the transmission network and would charge or discharge directly from or into the grid.

The batteries would also make use of the land, grid connection points and workforce skills at the site.

“The BESS will operate in the wholesale energy market by charging from the grid when supply is high and energy prices are low (typically during the day when solar generation is high),” the report says.

“This energy will then be discharged back to the grid when demand is high and energy prices are high (typically during morning and/or evening peak periods).”

The development report says the project would be subject to a number of other approvals before it could progress.

The project, if approved, would complement a similar stand-alone system planned to be built at the Tarong Power Station.

A spokesperson for Stanwell said the project would complement a similar stand-alone system that is planned to be built near the Tarong Power Station near Nanango in the South Burnett.

The projects are also expected to create dozens of jobs during the construction phase.

The spokesperson said battery storage was expected to play an important part as the energy market transformed and more renewable energy came online.

“Both batteries are located within renewable energy zones, supporting new build renewables to come online while also ensuring system security and reliability at key points of Queensland’s electricity network,” the spokesperson said.

“The projects will provide local employment opportunities, with each project creating around 80 full-time jobs over the construction phases, and six full-time jobs over the 20-year operation and maintenance phases.”
