AEMO completes pilot testing for world-first grid connections simulator

2 min

AEMO has completed pilot testing for its world-first ‘connections simulator’ ahead of an expected launch later this year. The simulator provides a cloud-based environment for users to run studies against AEMO’s model for new generation and storage projects connecting to Australia’s National Electricity Market (NEM).

Commencing in March 2022, the pilot included generation developers, power system engineering consultants and energy equipment manufacturers to test the end-to-end user experience, including portal access, features and navigation, and importantly running project modelling studies.

Merryn York, AEMO Executive General Manager System Design, said the innovative resource will support Australia’s energy transition.
“In the next decade, Australia will experience our first cluster of coal-generation retirements, equal to approximately 14 per cent of the NEM’s total capacity, which will challenge electricity reliability and power system security,” Ms York said.

“Replacing coal with low-cost renewables, supported by firmed generation and the timely investment in transmission, is needed to provide reliable, secure and affordable energy for all Australians.

“The Connections Simulation Tool will contribute by helping reduce risks, costs and time to approve the connection of new generation and storage projects, critical to replace retiring coal generation,” she said.

With funding support from the Australian Renewable Energy Agency’s (ARENA) Advancing Renewables Program, the connections tool is one of AEMO’s initiatives to streamline the connection process and experience for participants. Other projects include the Connection Reform Initiative, a partnership with the Clean Energy Council to remove delays and deal with the increasing complexity in connecting projects to the NEM.

During the year, AEMO registered 29 new generation and storage projects totalling 4 gigawatts (GW) of capacity, an increase of 1 GW from last year and 2 GW from the 2020-21 financial year. This included Australia’s largest battery (Victorian Big Battery, 300 MW), largest solar farm (Western Downs Green Power Hub, 400 MW) and largest wind farm (Stockyard Hill, 511 MW).

“In addition to the growth in the number of new projects and generation capacity, Australia is also breaking new ground with designing, testing and connecting new technologies, such as grid-forming batteries that provide inertia services,” Ms York said.

The overall number of projects undergoing AEMO connection assessment across the NEM now remains high, with 149 projects representing 22.3 GW at stages from application through to commissioning.
