Independent Panel - Gas Rate of Return Instrument

The National Gas Law requires the ERA to produce a gas rate of return instrument. The gas instrument sets out the methods the ERA will use to estimate the allowed rate of return and value of imputation credits for gas transmission and distribution service providers. These regulated gas pipelines are the Dampier to Bunbury Natural Gas Pipeline, the Goldfields Gas Pipeline and the Mid-West and South-West Gas Distribution Systems.

The ERA will review the current gas instrument and replace it with the 2022 Gas Instrument. This provides an opportunity to undertake a comprehensive review of approaches for determining the allowed rate of return on capital.

As part of the consultation process for the 2022 gas instrument review, the ERA will use an Independent Panel to review its draft gas instrument. The Independent Panel will review the draft gas rate of return instrument to ensure that the ERA’s approach is supported by sound reasoning and is capable of achieving the national gas objective.

As soon as practicable after the ERA publishes the draft instrument the Independent Panel will give the ERA a written report about the instrument.
