  • Economic benchmarking of Jemena Gas Networks' NSW gas distribution operations to assess relative efficiency and forecast productivity growth. Partial indicators, productivity index analysis and econometric cost functions were used in the analysis. Click here to see the report which JGN submitted to the AER as part of its 2019 Access Arrangement Proposal.
  • For three Victorian gas distribution businesses (AGN, Multinet Gas and AusNet Services) carried out productivity and benchmarking analysis to support their proposed access arrangements submitted to the AER in 2016. Click here to see the report "The Productivity Performance of Victorian Gas Distribution Businesses" and here for the report "Benchmarking the Victorian Gas Distribution Businesses' Operating and Capital Costs Using Partial Productivity Indicators".
  • On behalf of Multinet Gas, carried out econometric analysis of the gas distribution opex cost function to support its forthcoming access arrangement proposal (2016). Click here to see the report "Gas Distribution Businesses Opex Cost Function".
  • Advice to the Netherlands' Authority for Consumers and Markets on the use of data envelopment analysis (DEA) in energy network regulation. Our reports examined relevant issues for consideration in developing candidate variables to include in benchmarking studies of gas and electricity transmission system operators, in calculating capital costs, in choosing a preferred benchmarking model and in explaining and evaluating the results of the DEA benchmarking analysis.
  • For three Victorian gas distribution businesses (AGN, Multinet Gas and AusNet Services) carried out productivity and benchmarking analysis to support their forthcoming proposed access arrangements to be submitted to the AER (2016).

  • Report for the New Zealand Commerce Commission advising on the rate of change for the initial default price paths for gas pipeline businesses. The report assesses whether the long–run productivity growth rate of New Zealand gas transmission and gas distribution businesses has been significantly different from that of the New Zealand economy as a whole. It also examines available evidence on whether input price growth for New Zealand gas pipeline businesses has been significantly different to that for the New Zealand economy as a whole.
