Retail Competition Workshop - April 2011
Some submissions on Gas Industry Co's November 2010 Retail Competition and Transmission Capacity: Statement of Proposal expressed a strong preference for a non-regulated approach to improving competition in the retail market supplied by Vector's North Pipeline.
On 14 April Gas Industry Co held a workshop to explore ways to improve competition without regulation.

Retail Competition and Transmission Capacity Statement of Proposal: Submissions Analysis and Next Steps
Retail Competition and Transmission Capacity: Statement of Proposal
Date Published: 12 November 2010
In the paper Retail Competition and Transmission Capacity: Statement of Proposal, Gas Industry Co proposed introducing the Gas Governance (Constrained Transmission Pipeline) Rules.
The Rules are Gas Industry Co's preferred option for ensuring there are no unintended effects on competition arising from a TSO's commercial arrangements for transporting gas on constrained transmission pipeline.

The Bridge Commitments
The Bridge Commitments are a series of commitments made by the majority of shippers aimed at addressing short term concerns about competition on the North Pipeline. They have been in place since August 2011
Following the April 2011 Retail Competition workshop, key members of the gas industry put in place a package of measures to address the short-term issues large end users on the constrained North Pipeline were facing. The 'Bridge Commitments' comprise seven commitments. Notably each signatory supplier agreed that, where it supplies an end user, and that end user tenders its gas supply, it will make pipeline capacity available to competing suppliers.
Gas Industry Co assessed the Bridge Commitments and considered that they should:
· ensure existing large end users on the constrained North Pipeline have an effective choice of supplier in the short term;
· help to facilitate development of longer term access arrangements and investment; and
· materially change the market.
As a result of these conclusions, Gas Industry Co determined that intervention by way of Rules was not justified at this time.
Gas Industry Co will continuously monitor the effectiveness of the Bridge Commitments and update industry if anything occurs that may change its assessment.
In the mean time Gas Industry Co continues to work with the industry on the Gas Transmission Investment Programme. For more information on this work please refer to the 'Long-term' tab.

Investment and Access Workshop
Individual industry participants say that the need for new investment is a significant issue for the industry, possibly even the most pressing and important issue. Yet there is no forum in which key stakeholders are frankly discussing the issue.
On April 14, Gas Industry Co held a workshop to consider whether, how and when investment in additional North Pipeline capacity should occur, and what associated commercial access arrangements should be.
