Our GSD2023 was released just over 4 weeks ago. Finally today I have a chance to utilise the GSD2023 Data Extract to take a look across all the Semi-Scheduled units (i.e. Wind and Solar) and see who’s been using MaxAvail in their bid to limit their plant availability … and the DUIDs that have not yet used this new facility.
On Thu 29th Feb 2024 (a day when NSW saw high demand, was stretched in terms of available capacity, and benefited from the electricity and other services provided by soon-to-close Eraring) the Dept of Energy in Canberra released a Design Paper on the expanded Capacity Investment Scheme.

A short note about the publication of a richer MT PASA DUID Availability data set in ez2view v9.8 – made possible as a result of the other change that goes live in the NEM on Monday 9th October 2023
Very Fast FCAS, because it operates at a faster timescale, can arrest the rise or fall in frequency more rapidly than the current fast service and therefore provides an avenue to mitigate the costs of needing to procure increasing levels of the existing fast service. The markets (raise and lower) are going live on 9 October 2023.
A short note about the AEMC’s draft determination, published today.
A week’s worth of data provides indications of how semi-scheduled generators are using bid MaxAvail to manage dispatch availability.
It is indispensable to understand how the semi-scheduled unit availability gets produced to optimally manage the critical inputs and comprehend dispatch outcomes. This article explains the key inputs and processes, focusing on the dispatch timeframe.
