AEMO publishes Handbook for Wind and Solar Generators

Given our keen interest in supporting wind and solar generators in the NEM (via our ez2view software, through insights freely shared here on WattClarity, and through other methods discussed here) it was of interest that we noted that the AEMO has published their new ‘NEM Operational Forecasting and Dispatch Handbook for wind and solar generators’ today (Tue 11th Feb 2021):



A couple of our team had noted that the AEMO had announced (late last year in the two-part Intermittent Generation Forum) that this was on the way, so we were keenly awaiting.  Today their email says:

As previously communicated in AEMO’s Intermittent Generation Forum in November 2020, AEMO has prepared a handbook to provide general guidance to semi-scheduled generators, and non-scheduled intermittent generators with semi-scheduled obligations, about the requirements and expectations for registration and ongoing participation in central dispatch and related processes in the NEM. It highlights key requirements of relevant parts of the NER, and references formal guidelines, procedures and standards published by AEMO under the NER. The handbook provides an overview of:

•    Registration requirements from an operational forecasting perspective.
•    Integration into AEMO’s Australian Wind Energy Forecasting System (AWEFS) and Australian Solar Energy Forecasting System (ASEFS).
•    Ongoing requirements for data inputs for bidding and dispatch, pre-dispatch and PASA, and the potential consequences for generators and participants of inaccurate inputs to the AWEFS/ASEFS forecasting model, and non-compliant behaviour.
•    How generators can register and participate in self-forecasting.

AEMO plays a unique role in that it provides short-term forecasts of available capacity in the NEM on behalf of variable renewable energy (VRE) generators. With this role, AEMO is committed to assist the VRE industry in effectively managing generators and ensuring their obligations are met.

No doubt we will be referring back to this in future…


Speaking of outcomes on the Intermittent Generator Forum, now that the year has ticked over to 2021 we’re fast approaching Five Minute Settlement and so, in thinking about the structure of how bid data changes from 1st October 2021 (or sooner for some participants) we are keen to understand how some of Marcelle’s suggestions here for streamlining processes for Semi-Scheduled plant might be implemented?
