Connections Simulation Tool Project

The Connections Simulation Tool is a joint ARENA AEMO initiative.   

Securing a new grid connection for renewables has become a barrier to the transition of Australia’s energy system away from traditional energy sources. 

A world first, the Connections Simulation Tool will provide developers, Original Equipment Manufacturers (OEMs), Network Service Providers (NSPs), and consultants with a unique opportunity to streamline the approval of connection applications.   

This optional service provides applicants portal access to protected wide-area PSCAD models, equivalent to those used within AEMO. Simulations will show the network impacts of the prospective generator and rapidly verify that the plant can be securely connected to the National Electricity Market (NEM).  

Commercial and technical confidentiality will be preserved throughout the process.   

This aims to provide:   

Greater Confidence in Studies 

Connections applicants will be able to better design their generating system and be confident that the study outcomes will meet the acceptance criteria as defined in the rules.  

Faster Application Process 

Utilising a full power system model will provide applicants data and insights that will reduce the number of iterations with AEMO required to complete the connections process. The approval process will therefore be streamlined reducing risk, cost and time.  


The project aims to deliver the Connections Simulation Tool in the following timeframes.  

Connections Simulation Tool Trials. (2021 - 2022) 

A Minimal Viable Product (MVP) and BETA release trials will be conducted, collaborating with a small number of industry users.  

Connections Simulation Tool V1 release. (2022)  

PSCAD will be used to simulate network conditions. This will be available to a set of users that will be expanded over time. 

Related projects  

The AEMO Operations Simulator project will introduce HYPERSIM into AEMO operations. The Connections Simulation Tool was identified as an extension to that project providing further industry benefits.  

More Information  

Opportunities to find out more on the Connections Simulation Tool will be listed here including workshops, presentations, webinars, and forums. AEMO aims to provide regular updates to the industry over the coming months as this work progresses.
