Just wanted to get these charts of generation and demand out re the near blackout event last Feb. Full month large chart. Remember Liddell is slated to close early 2022.

3 days large chart. Intro from AEMO report – Keystone cops would have been right at home. In a nutshell – coal gen was off its highs achieved on 5th, 11th and at end of month. Gas was below specs. due mainly low gas supply – ironic for a State with gas exploration bans. Imports were spikey and Hydro were the big heroes in preventing blackouts. Wind ebbed away through the afternoon as of course did tiny solar.

From AEMO – SYSTEM EVENT REPORT NEW SOUTH WALES, 10 FEBRUARY 2017
Published 22 Feb 2017
1. INTRODUCTION
This report provides information on the operation of the National Electricity Market (NEM) and national
power grid in New South Wales on Friday 10 February 2017, during a heatwave in eastern Australia.
On Friday 10 February 2017, the eastern Australian states of South Australia, New South Wales,
Victoria, and Queensland all experienced high summer temperatures. Temperature forecasts for New
South Wales were overall lower during this day than actual temperatures.
New South Wales operational demand (energy demand provided from the grid) peaked at
1630 hours (hrs) at 14,181 megawatts (MW). 1 The New South Wales record peak operational demand
was on 1 February 2011, and was 14,744 MW.
The New South Wales Government publicly encouraged customers to reduce electricity use. AEMO
observed demand reductions of approximately 200 MW below forecast at the time of peak demand on
10 February 2017, which may have been due to customer responses. However, AEMO cannot measure
or verify the extent of the response.
Coincident with the peak of demand for the day, the following also occurred on 10 February:
 The forced outage of Tallawarra generators (408 MW) due to a fault in the gas turbine.
 Colongra units unable to start (600 MW), due to low gas pressure in the fuel supply lines.
 A number of thermal generators reducing output (details in Table 1).
 Reducing wind and solar photovoltaic (PV) generation of approximately 300 MW between 1700 hrs
and 1800 hrs (approximately in line with forecasts).
These factors, all coinciding at approximately 1700 hours, combined to overload the New South Wales
interconnections with Queensland and Victoria, creating an insecure operating state.
With no further generation available to serve the demand and relieve the overloading interconnectors,
as a last resort at 1658 hrs AEMO instructed TransGrid to reduce demand at the Tomago aluminium
smelter (290 MW) to restore the power system in New South Wales to a secure operating state. The
instruction was issued to restore load one hour later.
The sequence of events and data relating to the period are detailed in this report.
All times in this report are market time (Australian Eastern Standard Time (AEST)). In February, New
South Wales local time is market time plus 60 minutes.
Based on information at the time of this report, AEMO has assessed the adequacy of the provision and
response of facilities and services. In addition, AEMO has also assessed the appropriateness of actions
taken to restore or maintain power system security.
AEMO has found generally that all actions and responses of facilities and services were adequate
(operated as expected). AEMO intends to consider further whether plant capabilities during extreme
conditions are accurately reflected in bid and availability information.
