1. Gas Transmission Access Code: Next Steps following GIC Preliminary Assessment
27 March 2018

2. General support for continuing with GTAC process
Is GTAC materially better than MPOC / VTC?
YES NO
Discontinue single code process
Revise and consult on GTAC to address reasons

3. Comments on timeframe Refinement
7 submitters supportive of a 6 month of refinement process
Most parties noted that this would depend on the willingness to compromise
Submitters wanted to maintain momentum on GTAC
Balanced with need to avoid being schedule driven
IT and Approvals
Robust consultation process for GIC approval needs to be maintained and guidance on the time for this is required
First Gas wants to expand software system development to a 9 month timeframe
First Gas will not commit to software development without an approved code

4. Code Refinement - format going forward
Most submitters agreed that the following were important:
Continue with current workshop process
Single issue workshops
Independent facilitator
Making sure everyone was heard
Get to an agreed resolution prior to the end of the workshop
Other suggestions:
Involvement of independent experts on specific issues
First Gas is not the leader

5. Implications for timeline
Time to completion will depend on:
Number of issues that need to be resolved
Level of engagement and iteration required
Approach to gaining GIC decision
IT implementation
March 2018
Submissions on preliminary assessment
+ ? months
Further work on code development
+ ? months
GIC decision making process
+ 9 months
IT implementation programme ?
