NGET - Capacity Market Rules CP326
Change Proposal
Publication date
Currently when a New Build CMU has not been finalised by the start of the Delivery Year they still receive payments. If that CMU does not finish the project after a year then the payments are recouped via lack of Satisfactory Performance Days (SPDs). If for example, the CMU is built 3 months into the Delivery Year they could continue to get payments throughout the whole year (if they fulfil their SPDs) despite not being there for the entire period. The Delivery Body therefore recommends that the Auction Acquired Capacity Obligation (AACO), defined in Rule 8.5.3, is set to zero pending Substantial Completion or Minimum Completion by the start of the Delivery Year. Related to this change, we consider it appropriate to allow the Delivery Body to change the AACO of New Build CMUs who meet Minimum Completion but not the Substantial Completion Milestone. Rule 6.7.1 should be amended to include Minimum Completion ie “A Capacity Provider is not liable for, or entitled to, any payments in respect of a particular CMU if the relevant System Stress Event precedes the date on which the Substantial Completion Milestone, or failing that Minimum Completion Milestone, for such CMU is reached”. In addition the Delivery Body believes that there should be more formal reporting for Minimum Completion. With Substantial Completion Milestones, an ITE signs off reports, we believe that we should align this process with Minimum Completion for assurance purposes.
