About clause 2.16 notices
Clause 2.16 of the Electricity Industry Participation Code 2010 allows the Electricity Authority to issue notices that require industry participants to provide specific information, including on a regular basis or in response to events, to assist in monitoring and understanding the market.
We consult with market participants before issuing a notice under Clause 2.16 to ensure the information requirements are workable and the outcomes can be delivered at a reasonable cost.
The notices allow the Electricity Authority to collect and publish data, information and tools to help monitor the industry and electricity markets. It helps to improve participation in and understanding of the electricity markets by the Authority, industry participants and consumers. It also helps us to put in place the right rules to ensure the electricity system runs smoothly.
