For customers looking to provide market services, the Gridcognition software allows you to model potential revenue from all six contingency FCAS markets in the NEM. By default, we use the last 12 months of historical contingency FCAS prices published by AEMO. The prices are cast forward for future years. The prices are capped at the 75th percentile for each market for each month to avoid ‘over indexing’ on volatile historical events that would have a very significant bearing on the future forecast. The price is averaged for each market for each month – the expected value for randomly occurring events should be equal to the mean.
