As part of a review of the effectiveness of the framework of economic regulation applying to gas pipelines in Australia, Brattle was retained by the Department of the Environment and Energy and the Australian Energy Regulator to review the financial disclosures of 14 pipelines. Identified inconsistencies in the reported information across pipelines and over time. Assessed the usefulness of the disclosed information, and in doing so, discussed the framework to use the reported information to calculate pricing benchmarks for accessing the pipelines. Estimated the pricing benchmarks for each pipeline. Suggested recommendations to improve the consistency, clarity, and usability of future reporting.
