The recovery of payments for Regulation Services is based on the 'causer pays' methodology. Under this methodology, the response of measured generation and loads to frequency deviations is monitored and used to determine a series of causer pays factors.
Non Market Ancillary Services Annual Summary
AEMO is required, under the clause 3.13.5 of the National Electricity Rules (Rules), to publish annually the quantities and types of NSCAS covered under existing ancillary services agreements. This only covers services acquired by AEMO to meet an ‘NSCAS gap’ in accordance with the requirements of the Rules. AEMO does not report on NSCAS acquired by TNSPs.
