Gas form of control discussion document released
The Commerce Commission has released its proposals for the form of control to be imposed on the gas distribution
services of Powerco and Vector.
The discussion paper provides a comprehensive review of the issues that the Commission considers are relevant to
determining the final form of control. At present control is administered by way of a Provisional Authorisation.
Submissions are invited from all interested parties, including economists and lawyers working in the regulatory area,
and major gas consumers.
The Commission has considered the following broad forms of control to determine the appropriate form of control for the
Authorisation:
rate of return regulation;
total revenue cap;
average revenue cap;
weighted average price cap;
disaggregated price cap; and
sliding scale regulation.
The Commission’s preliminary view is that the weighted average price cap is the preferred form of control for standard
consumers. For the non-standard customers and metering services the total revenue cap is the preferred form of control.
A table in the background section of this media release is a summary of the proposed control terms for the three types
of control groups.
The discussion paper poses specific questions in relation to the Commission’s proposals, and the Commission also
welcomes wider comments. Questions posed by the discussion paper include:
Are there any other options for the form of control that the Commission should be considering?
Are there issues with a five year initial control period of the Authorisation, starting on 25 August 2005?
Are there issues with using financial incentives to regulate quality?
Submissions on this discussion paper are due by 7 August.
A conference on the form of control is now planned for 5 and 6 September. The conference allows key interested parties
to present their submissions to the Commission. The submissions, conference, and cross submissions will inform the
Commission’s decisions. The Commission’s draft decisions will be presented for further consultation in early 2007.
The document’s full title is Authorisation for the Control of Supply of Natural Gas Distribution Services by Vector Ltd
and Powerco Ltd Form of Control - Discussion Paper.
