Changes to constrained-on provisions of the Code

The Authority continually monitors market pricing and payments to ensure that the market operates in an efficient and competitive manner. The Board has noted the recent significant increase in generator constrained-on payments and is concerned some of these payments do not reflect the cost to generate.

We are reviewing the constrained-on provisions of the Code. In early 2019, we intend to consult on a proposal to remove constrained-on payments made to generators when plant has been dispatched down at its maximum offered ramp rate (i.e. ramp rate-constrained).
