GSI Rule Changes

Amending Rules Proposed by the Minister

The Public Utilities Office (PUO) is currently preparing amendments to the GSI Rules to facilitate the abolition of the Independent Market Operator (IMO). These Amending Rules are to be approved by the Minister and published in the Gazette. These Amending Rules are to be made in conjunction with regulations to dissolve the IMO, and will come into effect on a date determined by the Minister, likely to be in April 2018.

The PUO previously consulted on the Amending Rules, and comments closed on 9 March 2018. A copy of the Amending Rules that were the basis of this consultation are available here: Draft amendments of GSI Rules for IMO abolition

Please contact the PUO by email at if you would like further information.
