The CEC supports the changes proposed by AEMO in the ISP methodology issues paper to address the actions identified by Energy Ministers in their response to the review of the ISP with a view to better integration of gas and suggests considering the lack of co-optimisation between the gas supply expansion model and electricity models, how alternative investment or technology could be used to meet any gaps in the gas requirements (such as electrification) and tradeoffs in relation to electricity and gas generation and infrastructure.
The CEC is supportive of expanding the ISP’s analysis to include a greater consideration of the existing and future distribution network capabilities driving integration of CER and other distributed resources but notes the ability for AEMO to access relevant information regarding distribution network hosting and augmentation capacity will be essential. To that end, the CEC recommends AEMO establish a reference group with DNSPs to meet regularly and discuss information building capacity with each consecutive ISP.
