The requirement for the very fast raise contingency service is set to increase to 100 MW. We review availability and bids to consider the impact.
An article in the Australian this morning alerted me to yesterday’s Federal Court ruling against AGL Energy for not supplying contingency FCAS services (from Bayswater and Loy Yang A) when enabled by NEMDE. Here’s a quick look…
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.
Following the low levels of demand over the weekend (Sat 16th and Sun 17th Sept 2023) here’s a few quick notes.
Don’t forget about FCAS when the energy market starts to steal the spotlight.

A first after-the-fact review of the price volatility seen in QLD and NSW on Tuesday evening, 2nd May 2022. What were some of the causal factors?
On Thursday 17th March, Jonathon Dyson presented at the CEC Wind Industry Forum in Melbourne about the increasing role of auto-bidding and self-forecasting in the modern-day NEM. In this article, he shares some of the key points from that presentation.

A rainy Saturday morning reminds us the price volatility for Q2 in QLD has not totally gone away … with elevated prices for ENERGY and also Contingency FCAS (Raise 6 second and Raise 60 second).
High Contingency FCAS prices (Raise 6 second) in response to what’s happened at Callide Power Station drove the Cumulative Price to (6 times) the Cumulative Price Threshold. Administered Pricing began Saturday evening for QLD.
