Amendments and clarifications

On this page you can find input methodologies related correspondence. From time to time the Commission may also publish updates on process relating to input methodologies.

Correspondence and process updates published up to December 2010 can be located under Consultation Prior to December 2010.

On 8 March 2011 the Commission published a memorandum on its process for considering requests for amendments or clarifications of the Part 4 determinations it made in December 2010. This memorandum can be located below under the heading 'Amendments to Determinations', along with a summary spreadsheet of the Commission's responses. Requests for amendments or clarifications and the Commission's full response are published on the input methodologies page for the relevant regulated service(s).

For information on the input methodologies review, see the input methodologies review page. Note that consideration of IRIS for gas pipeline businesses will now be made as part of the review of input methodologies.
