Summary
The National Electricity Rules, made by the Australian Energy Market Commission (AEMC) under the National Electricity Law and having the force of law, govern the National Electricity Market (NEM) across Queensland, New South Wales, the ACT, Victoria, South Australia and Tasmania. Chapter 2 sets the categories of Registered Participants, the eligibility criteria and unit classification requirements for each category, the registration process with the Australian Energy Market Operator (AEMO), transfer and cessation of registration, and how AEMO sets participant fees. Once registered, participants must meet the market rules in Chapter 3 (bidding, dispatch, prudential requirements, settlements, information to AEMO), the power system security obligations in Chapter 4, the metering obligations in Chapter 7 and confidentiality duties. The Australian Energy Regulator (AER) monitors bidding, rebidding and compliance and enforces breaches.
