Energy Trading System (ETS) - Reporting Changes for Unit Commitment Directive Settlement

The AESO will be implementing a new public settlement report and changes to several market participant specific settlement reports that require the use of a digital certificate to access in the Energy Trading System (ETS). These changes are related to the Supply Cushion Regulation, where a pool participant who has received a unit commitment (“UC”) directive for their long lead time asset may be eligible to recover incremental generation costs.  Unit commitment payments and the charged volumes associated with production and consumption in each settlement interval will be reflected through a new public facing settlement report. There will be the addition of extra columns or rows, and an update in format, to several settlement reports.

Public Settlement Report (New)

• UC Summary Report

Market Participant Specific Settlement Reports

• Daily Detail (Production and Consumption)
• Daily Summary (Production and Consumption)
• Monthly Summary (Production and Consumption)
• Settlement Changes (Production and Consumption)
• Pool Statement

The change will take effect after release on Aug. 28, 2024. The UC Amount ($), UC Payment and UC Charge will display either empty or zeros until a UC payment is settled.

Below are visuals of the upcoming changes:
