Government Policy Directions

July 2025 Direction Letter

• The AESO will also continue to work with stakeholders on developing a long-term congestion management approach to provide appropriate risk management to support ongoing investability in our market.

July 2024 Direction Letter

• Move away from the current zero-congestion planning standard to an optimally planned transmission planning standard
• Allocate new transmission infrastructure costs and all ancillary services costs based on cost causation principles

December 2024 Direction Letter

• AESO will develop a market-based congestion management mechanism that recognizes incumbency, provides impacted generators with a means of managing the dispatch risk arising from congestion constraints
• Implement a cost allocation framework for new transmission infrastructure based on cost-causation principles by requiring new generators to contribute to transmission infrastructure costs by replacing the Generating Unit Owner’s Contribution (GUOC) with an upfront and non-refundable TRP
• TRP rates will be calculated as a function of the suppliers’ proximity to transmission capacity, their technical attributes and characteristics and the cost of reinforcing the transmission system
