Planned outage of Heywood No.1 500kV Bus in Victoria region from 10/08/2016 0700 hrs to 12/08/2016 1700 hrs
AEMO ELECTRICITY MARKET NOTICE.
This market notice is FOR INFORMATION ONLY.
The Heywood No.1 500 kV busbar in Victoria Region is planned out of service from 0700 hrs on 10 August 2016 to 1700 hrs on 12 August 2016. During this outage, Heywood 500/275 kV M1 transformer will be off-loaded and Heywood - Tarrone - Alcoa Portland No.1 500 kV line will be open at Heywood.
During this outage, a credible contingency can separate South Australia region from the rest of the NEM.
Under these circumstances, 35 MW of Raise and Lower regulation FCAS will be sourced from South Australia for the duration of this outage. In addition, consistent with AEMO existing procedures, adequate contingency FCAS lower requirements will also be sourced from South Australia at times when power transfer is from South Australia to Victoria.
The following constraint sets have been invoked for this outage:
F-I_HYSE (includes F-S_LREG_0035 and F-S_RREG_0035)
S-BOTH_BLKRG_C_OS
V-HYTX_M12
V-HY_500BUS

Planned outage of Tailem Bend 275kV - South East 275kV No.2 line from 16/07/2016 0745 hrs to 24/07/2016 1730hrs
Planned outage of Tailem Bend - South East No.2 275kV line from 16/07/2016 0745 hrs to 24/07/2016 1730hrs
?
During this outage, South Australia (SA) will remain connected to the NEM via the Tailem Bend - South East No.1 275kV line and the 132kV network.
?
A trip of the Tailem Bend - South East No. 1 275kV line will sever the 275 kV connections between the NEM and SA. SA will remain connected to the NEM via the 132kV network, which if it remains in service will pose a system security issue.
?
In the event of a trip of the Tailem Bend - South East No. 1 275kV line, AEMO will invoke FCAS regulation constraint sets F-S_LREG_0035 and F-S_RREG_0035
?
In addition,? AEMO will take all necessary steps as outlined in Section 6.1 of SO-OP-3715 Power System Security Guideline to separate the 132kV network and therefore manage an orderly separation of SA from the NEM.?
