The Authority is interested in receiving economic modelling and information that other parties may have to assist the Authority's consideration of options for the transmission pricing methodology (TPM) review.

In March 2012, the Authority met interested parties to discuss the decision-making and economic framework for the review. At the meeting with Meridian, the Authority was offered access to Meridian's economic modelling and information used in preparing its submissions to the consultation paper on the decision-making and economic framework for the TPM review. The Authority last week accepted Meridian's offer and is interested in receiving similar information from other parties.

The Authority will review all information received, and will decide what information might be included in the consultation paper intended for release in September 2012.

The Authority will publish economic modelling and information that it receives on its website.

Professor Bill Hogan visited the Authority on Friday 20 July. In addition to meetings with consumer, industry and Authority personnel he gave a two-hour presentation to invited guests on competitive electricity markets and his approach to deciding transmission expansion and transmission pricing.
