Previous WA GSOO 5-year reviews
Five-Yearly Review - August 2018
The WA GSOO was first published by the Independent Market Operator (IMO) in 2013. In 2015, certain IMO functions transferred to AEMO, including the responsibility for developing and publishing the WA GSOO. AEMO has published the WA GSOO from 2015 onwards. Modifications have been made annually to improve the modelling methodology and forecasting accuracy, to increase engagement with stakeholders, and to address issues of importance to the WA gas industry.
