Background
Network Control Ancillary Services (NCAS) are transmission network services procured by NEMMCO that are critical to the maintenance of secure and reliable operation of the power system, by providing the capability to:
- Maintain the transmission network within its current, voltage or stability limits following a credible contingency event; and
- Enhance the net value of spot market trading by increasing transmission network power transfer capability within those limits.
NEMMCO is required under Clause 3.1.4(a1)(4) of the National Electricity Rules to conduct a review into the provision of NCAS, or NSCS in general (“the NSCS Review”), in consultation with Registered Participants, Intending Participants and interested parties and in accordance with Rules Consultation procedures.
Objectives of the Review
The objectives of the NSCS review are:
- To identify and address issues surrounding the current arrangements for the procurement and delivery of NSCS by TNSPs and NEMMCO; and
- To identify, evaluate and make recommendations on potential alternative arrangements for the more efficient procurement and delivery of NSCS, in accordance with the Rule obligation
