South Australia household batteries keeps lights on in Queensland after coal unit fails

Print Friendly, PDF & EmailThe South Australia government and the Australian Energy Market Operator have hailed the success of the state’s solar and battery virtual power plant, after it came to the rescue during an unexpected coal power outage in Queensland last month.AEMO said on Friday that on October 9, the South Australia VPP – which currently combines the stored solar resource of hundreds of homes with rooftop PV and storage – injected energy into the National Electricity Market (NEM) in response to a large generator outage in the Sunshine State.
The outage at Queensland’s Kogan Creek coal power station happened when the unit – the biggest single unit in Australia – tripped, reducing supply by 784MW, and causing the power system to drop well below the normal level of system frequency.The VPP detected the frequency drop and immediately injected power into the grid from residential batteries installed on SA Housing Trust properties across the state, contributing with other providers to return the system back to normal, said South Australia energy minister Dan van Holst Pellekaan in a separate statement.

Costa Rica went entirely renewable. Well, almost. The residents still drive gas-powered cars, but the electrical grid used 98% renewables for the year. That’s an incredible feat, and one that larger countries have been unable to accomplish. Of course, the smaller population and the pleasant temperatures have some effect but does little to dampen the accomplishment. Costa Rica has become a positive example to encourage larger nations to follow suit.

“Although the Virtual Power Plant is in its early days, it is already demonstrating how it can provide the network support traditionally performed by large conventional generators,” the minister said.The South Australian Virtual Power Plant, which has more than 900 systems installed so far, has been led by US battery and EV maker Tesla, with support from the South Australian government and energy retailer Energy Locals.In September 2019, the offer was expanded to private households through the Tesla Energy Plan.
The outage information was captured by AEMO through its VPP demonstrations program, in which the Housing Trust-based Virtual Power Plants has been participating since mid-September.AEMO’s executive general manager of emerging markets and services, Violette Mouchaileh, said the VPP had proven that coordinated home batteries could benefit the broader power system, including other consumers.“The SA VPP has proven the aggregation of distributed energy resources can benefit the power system and participating consumers,” Ms Mouchaileh said.

energy sources are used, the demand for fossil fuels is reduced.

“The opportunity for VPPs to reach a large scale will benefit all energy users through added competition to deliver services at reducing prices.

“We encourage more VPPS to register to accelerate the shared learning on how to safely and efficiently integrate, operate and regulate these emerging technologies into the NEM,” she said.
