Infrastructure WA

43. Enable transformation of the South West Interconnected System by evolving the Whole of System Plan and ensuring implementation actions are transparent, including:  

1. updating modelling inputs, assumptions and scenarios to incorporate the following: 
   • achieving interim emissions reduction targets (once defined) and net zero emissions by 2050 targets through the lowest-cost mix of generation, storage, network transmission and distribution
   • potential renewable energy generation locations on the network, such as the Mid West, on energy network infrastructure requirements 
   • electricity offtake associated with the development of new industries in line with state government industry development objectives
   • potential entry of existing off-grid large users connecting to the South West Interconnected System and rates of potential electrification across commercial, industrial and residential users
   • using technologies (such as energy storage) to reduce the curtailment of renewable energy generation, and the practicality and community acceptance of any curtailment assumptions 
   • accelerated delivery of energy storage and other Distributed Energy Resources technologies, including the impacts these have on the overall energy infrastructure investment program 
   • increased uptake of electric vehicles on the energy network, including increased demand for energy and energy storage opportunities from electric vehicle batteries  
2. publishing a detailed short-term to medium-term implementation plan for the most likely scenario, which is updated periodically and identifies:
   • current and planned investment
   • network constraints
   • opportunities for investment in programs and projects to deliver energy transformation, including the nomination of priority projects eligible for streamlined approval processes.
