Commencement of the Formal Rule Change Process

The formal Rule change process under the Wholesale Electricity Market Rules (the “Rules”) commenced on 15 December 2006.

The table below details the final status of the Rule change proposals received by Office of Energy whilst it was administering the Rule changes process on behalf of the Minister for Energy.

The Office of Energy will no longer accept any further Rule change proposals.
