Under rule 15.2 of section III of part F of the Electricity Governance Rules 2003, a designated transmission customer, an authorised representative of parties substantially affected by the Grid Upgrade Plan, or Transpower, may, within 10 working days of the date of publication of the notice of intention (that is, by 5pm on 17 July 2009), request that the Commission hold a public conference if they consider that:
