55033MARKET SUSPENSION29/09/2016 10:04:25 AM
South Australia Market suspension update
Further to Market Notice 54987 and 54989 issued at 16:27 and 16:32 respectively on 28/09/2016.
AEMO confirms the conditions for suspension of the electricity spot market in the South Australia region described in clause 3.14.3(a) of the National Electricity Rules (NER) remain in place. Although a substantial amount of load has been restored in South Australia, AEMO is unable to operate the spot market in significant parts of the north of South Australia in accordance with normal dispatch processes. Consequently the spot market in South Australia remains suspended until further notice.
For the duration of the suspension, spot prices and ancillary service prices in South Australia are determined by the relevant market suspension pricing schedule developed and published in accordance with clause 3.14.5(l) of the NER. The schedule is available on AEMO's website at https://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data/Market-Management-System-MMS/Market-Suspension-Default-Pricing-Schedule.
Prices in the DISPATCHPRICE report will be substituted with prices for energy and ancillary services in the published market suspension pricing schedule (see Market Notice 54989). The suspension flag in the report is only changed once those prices have been substituted. We are working on uploading the suspension prices as soon as possible.
Suspension pricing will be applicable until AEMO issues a further market notice lifting the spot market suspension. AEMO will give four hours notice prior to lifting the spot market suspension.
AEMO will then review prices in other regions as required by the National Electricity Rules, within one business day after the suspension is lifted. Spot prices in other NEM regions that have had actual flow towards South Australia may also need to be capped in accordance with clause 3.14.5(m). This will also be done as soon as practicable.
