3.1 About availability
To facilitate intermittent generation forecast accuracy, the availability interface allows
participants’ operational staff to input the following information for intermittent generating
units:
l
l
Upper MW Limit: An MW limit applied in the intermittent generator’s control
system to limit its MW output to below the limit.
Elements unavailable: The number of elements (turbines, strings and so on) within
each cluster that are unavailable for generation (due to maintenance, turbines not
being built, or the inability to generate because transmission or distribution networks
are unavailable).
A cluster is a group of intermittent generating units; there may be more than one cluster in
an intermittent generator. AEMO may agree to have non-identical elements in a cluster in
exceptional circumstances.
The resolution for entering the above information is 30 minutes for pre-dispatch and ST
PASA (where eight days data is entered), whereas daily information is in the MT PASA time
frame (where two years of data is entered).
The Upper MW Limit and Elements unavailable do not apply to the Dispatch and 5 minute
Pre-dispatch time frames – local limits in these time frames can be managed by adjusting
generator bids.

Guide to Intermittent Generation
In this menu you can:
l

l
View availability information for Energy and MT PASA.
Enter availability information (Elements Unavailable and upper MW limit) for Energy
and MT PASA.
l
l
Enter elements unavailable for each cluster.
l
Enter an upper MW limit for each intermittent generator.
3.2 Availability submission guidelines
In this section:
3.2.1 Upper MW limit submission
12
3.2.2 Elements unavailable submission
13
3.2.1 Upper MW limit submission
For the Upper MW Limit entries enter an integer value not greater than the registered MW
capacity of the intermittent generator. For example, if an intermittent generator has a
capacity of 150 MW, and a participant user enters 200 MW as the Upper MW Limit, the
system generates a suitable error message prompting them to enter the information again.
Notes:
l
l
Zero is a valid entry meaning the intermittent generator is restricted to a zero limit, so
is not allowed to generate any electricity.
The unrealistic value of –1 means there is no availability limit in place on the
intermittent generator. This is the default situation.
There are two columns for each registered cluster in the intermittent generator, being the
Elements Unavailable and MW Available. The Elements Unavailable column header reflects
the cluster element corresponding to each generation technology. For example, for wind
farms the column header shows Turbines Unavailable and for solar farms the column header
shows Strings Unavailable. Enter the number of unavailable elements in the cluster under
Elements Unavailable and the system calculates the available power (MW Available).
Adding new clusters is part of the registration process with AEMO, and cluster
characteristics cannot be altered using the energy market systems web portal. To add new
clusters, contact the AEMO Information and Support Hub.

12
Chapter 3 Availability
3.2.2 Elements unavailable submission
For the Elements Unavailable entries ensure the number of elements does not exceed the
total number installed in the cluster. For example, if a participant user enters six under
elements unavailable for a cluster with only five, the system generates an error message
prompting you to enter the information again.
Only enter the total number of elements unavailable in a cluster with non-identical elements.
The system assumes each of them to be the average size in the cluster. For example, consider
an wind farm cluster with 40 turbines each with rated capacity of three MW and 10 elements
of 4 MW rated capacity. The cluster has 50 turbines and the cluster rated capacity is (40 X 3
MW) + (10 x 4 MW) = 160 MW. If four of the four MW elements and two of the three were
unavailable, then just enter six unavailable in total. The system uses the average size of the
cluster for each of the six unavailable turbines (such as, a rated capacity of 3.2 MW each,
being 160 MW/50 elements).
Notes:
l
l
Enter whole numbers of elements only. A zero entry is a valid entry (meaning that
none are unavailable, or equivalently that all elements in the cluster are available).
Negative numbers are invalid.
The default value is either blank or zero.
3.3 About derivation of MW Available from elements unavailable
In this guide, capacity is usually measured as energy in a trading interval (half-hour period).
Dispatch is every five minutes with financial settlement every half-hour (the trading
interval). Forecasting data, and thus availability data, uses the trading interval as its time
basis.
In this section:
3.3.1 Cluster Rated Capacity
13
3.3.2 MW Available
14
3.3.1 Cluster Rated Capacity
Each cluster has the rated capacity of the sum of rated capacity of all the elements (for
example, turbines for a wind farm or strings for a solar farm) in the cluster. If each element
in the cluster has the same capacity, the rated capacity of the cluster is the number of
elements in the cluster multiplied by rated capacity of each element. For example, consider a
wind farm with 50 turbines of 3 MW. The Cluster Rated Capacity is (50 X 3 MW) = 150 MW.
© 2016 AEMO
13
Guide to Intermittent Generation
The average turbine rating for this cluster is the same as each turbine (such as, 3 MW),
equivalently calculated as 150 MW/50 = 3 MW.
If AEMO agreed to include non-identical element types in a registered cluster, then the
calculation involves the grouping of like-capacity elements. For example, consider a wind
farm cluster with 50 turbines (installed turbines) in total. In this cluster, the rated capacity
of 40 turbines is 3 MW each and 10 turbines are of 4 MW. In this scenario, the Cluster Rated
Capacity is (40 X 3 MW) + (10 X 4 MW) = 160 MW. The average turbine rating for this
cluster is 160 MW/50 = 3.2 MW.
3.3.2 MW Available
The MW available for a cluster is the Cluster Rated Capacity less the multiplication of the
number of unavailable elements by the average element capacity of the cluster. This is
equivalent to MW Availability = Cluster Rated Capacity – (number of Elements
Unavailable X Average Element MW Rating). For example, consider a wind farm with
50 identically-rated turbines of 3 MW in a cluster, with 22 of these unavailable due to
planned maintenance:
MW Availability
= Cluster Rated Capacity – (Elements Unavailable X Average Element MW Rating)
= 150 MW – (22 X 3)
= 150 – 66
= 84 MW
Or, consider a wind farm with 50 non-identical turbines (40 of 3 MW and 10 of 4 MW) in a
cluster, with 4 x 4 MW and 2 x 3 MW of these unavailable due to planned maintenance:
Cluster Rated Capacity
= (40 x 3) + (10 x 4)
= 120 + 40
= 160 MW
Average Element MW Rating
= 160/50
=3.2 MW
MW Availability
= Cluster Rated Capacity – (Elements Unavailable X Average Turbine MW Rating)
= 160 MW – (6 X 3.2)
= 160 – 19.2
= 140.8
= 141 MW (after rounding to integer)

3.5.5 Submit energy availability using FTP
About using FTP
Intermittent generators can submit their energy availability in aseXML format, using FTP, to
their participant inbox directory on the EMMS file server. The aseXML file is compressed
inside a .ZIP file with one aseXML file per .ZIP file.
Participants receive an acknowedgement (.ACK file) in their outbox directory advising of a
successful or failed submission. The Intermittent Generation application handles the
decompression of incoming files for processing and compressing of .ACK files. The message
acknowledgment indicates success or failure of the incoming file (for example, does it
conform to the aseXML schema?). Each transaction within the incoming aseXML file is
acknowledged with a separate transaction acknowledgement file. The transaction .ACK
indicates success or failure of uploading the data in the transaction (for example, Does it pass
business validation rules and was it successfully added to the database?). If errors are
encountered in either the message or a transaction, the .ACK file includes relevant error
messages.
It is participant's responsibility to remove the .XML file from their inbox directory after
receiving the .ACK file from AEMO in their outbox directory.
The XML file must pass the following validations:
l
l
l
l
l
It must be placed in the same participant ID inbox directory on the EMMS file server
as the participant ID in the file, otherwise it will not be processed.
There is only one participant ID per file, you cannot submit one file for multiple
participants.
There is only one transaction section per XML file.
The Trading Date is in the following format: YYYY-MM-DD.
The Cluster ID must be valid.
In the XML file, only enter the required period IDs, you do not need to include Period IDs 1–
48, see Figure 10 on page 33.

Guide to Intermittent Generation
Creating XML files
To create XML files, participants can use an application such as XML Spy. For an example of
the aseXML schema and and energy availablility XML file, see "Energy availability aseXML
schema examples" below.
For more details about the aseXML standards, guidelines and file examples, see aseXML
Standards.
Uploading XML files
Participants can setup the Participant Batcher software (this is a different application to the
pdrBatcher used for Data Interchange) to move files between their participant gateway and
the EMMS file server. To obtain the Participant Batcher software and user guide, see Using
Energy Market Systems.

3.7.1 About MT PASA availability
Wind generation forecasting in the MT PASA time frame involves predicting the wind
generation peak demand half-hour period during the day. Therefore, providing MT PASA
Availability means providing the maximum energy expected to be available from each unit in
any trading interval in the day (such as, half-hour period), together with the number of
unavailable elements in each cluster in the unit in that same trading interval.
You can enter MT PASA availability submissions manually into the Create MT PASA
availability submissions interface or you can upload a prepared file in CSV format from
your computer, see "Upload MT PASA availability" on page 38.

being identified by a region ID (such as: SA1, VIC1, TAS1, NSW1, QLD1).
Only regions with intermittent generating units have data available.
Visibility of forecasts is limited. For example, only owners, their participant users and their
TNSP can see all forecast periods for a single intermittent generator. TNSPs can see forecasts
for all intermittent generators in their respective regions. The regional forecasts are
available in real-time to all participants, whereas the individual intermittent generator actual
MWs for a given day are made available the following trading day (such as after 4.00 am
next day).
The types of forecasts are:
l
Dispatch (DS)
l
5-minute pre-dispatch (5MPD)
l
Pre-dispatch (PD)
l
Short-term Projected Assessment of System Adequacy (ST PASA)
l
Medium-term Projected Assessment of System Adequacy (MT PASA)
The DS and 5MPD forecast is at the medium reliability level (probability of exceedence POE - of 50%). For other forecast types, the forecast information is at three different
reliability levels, being low, medium and high POE (90%, 50% and 10% respectively).

5.2.1 About overriding forecasts
The Intermittent Generation Overrides Creation interface provides ability for
participants to input forecasts for their own intermittent generators covering all time frames,
except dispatch (such as, 5-minute pre-dispatch, pre-dispatch, ST PASA and MT PASA). If a
forecast override is entered by a participant, the Intermittent Generation web application
automatically applies those forecasts to the applicable time frames. The business rules
include:
l
l
AEMO uses discretion in using participant supplied forecasts and can cancel those
forecast overrides.
AEMO overrides always take precedence over participant overrides.

5.2.2 Enter an override
To create an override for a selected unit:
1. Place your cursor over Intermittent Generation, then Forecasts, then Override
and then click Enter Overrides.
2. The Intermittent Forecast Overrides Creation interface displays, similar to the
one below. Initially the interface displays the first Unit for the participant, the
Profile Start Time as the nearest half-hour time in the future, the Profile End
Time as two hours from Profile Start Time and four rows of half-hour periods.
The interface allows the entry of details to override a forecast for a nominated
participant unit over a given time range.
You can also:
l
Select another Unit: Click the down arrow to the right of the Unit item to show the
list of visible units. Selecting a unit in the Forecasts Overrides window displays the
overrides for the selected unit, according to the other selection; see 2.7.1 "Select the

l
l
l
The Profile Start Time is the date and time when the forecast override takes effect,
initially set to the nearest half-hour time in the future.
The Profile End Time is the date-and-time when the forecast override ceases to be
active, initially set to two hours from Profile Start Time.
At the time of submission, the Profile Start Time must be in the future (and, since
the Profile End Time must be after the Profile Start Time, so must the Profile
End Time also be in the future).
Changing either date causes the interface to show rows for each half-hour spanning
from the half-hour boundary on or after the Profile Start Time to the half-hour
boundary on or after the Profile End Time, with each row having empty POE fields.
Each row starts and ends on a half-hour boundary.
5.2.4 Enter a reason
The Reason is the description of the circumstance causing the override of the forecast. For
successful submission, a reason is mandatory. It can be longer than displayed on the interface
but only the first 200 characters are accepted by AEMO for processing.
