On May 28th, 2026, the Town of Hinton (the Town) filed a compliance application with the Alberta Utilities Commission (AUC or Commission) in proceeding 30867 regarding a reassessment of appropriate water rates concerning Mondi Hinton Inc. (Mondi). This proceeding is a continuation of an earlier AUC decision, in which the Commission found that the Town had improperly imposed rates to its customers.
On June 19th, Fortis Alberta Inc. (Fortis) filed with the Alberta Utilities Commission (AUC) its arguments regarding the appropriate compensation for the transfer of service-area sites and distribution assets from the Battle River Power Coop (BRPC). After the Alberta Court of appeal rejected an earlier Commission ruling, Decision 28358-D01-2024, the AUC initiated proceeding 30555 to redetermine how much Fortis should compensate BRPC under an alternative section of the relevant Hydro and Electric Energy Act (HEEA).
In proceeding 30895, ATCO Electric Ltd. (ATCO) filed a notice of dispute (Form B) with the Alberta Utilities Commission (AUC) on June 11th, contesting the micro-generation application of a customer in Sherwood Park, Alberta. The dispute involves whether the customer’s proposed 10kWh combined heat and power (CHP) unit qualifies as micro-gen under the existing Micro-Generation Regulations (MGR).
On March 31, 2026, the Alberta Electric System Operator (AESO) held a workshop concerning the Internal Demand Rate (IDR) revamp. Previously called the ISO tariff, the new name reflects the fact that the current tariff application changes are part of the broader Restructured energy market (REM). The goal of this workshop was to engage stakeholders and solicit feedback on potential transmission rate design features.
For context, the AESO had last asked for approval for a tariff redesign in 2021, but was rejected by the Alberta Utilities Commission (AUC). While not set in stone, many of the features discussed in the recent workshop were heavily based on earlier AUC feedback.
On January 30, 2026, the Alberta System Electric Operator (AESO) released its Optimal Transmission Planning (OTP) Framework, outlining significant changes to the transmission planning process as part of the broader restructured energy market (REM).
The new framework was released following significant stakeholder feedback earlier in Fall 2025. This included submissions from ENMAX, ATCO Electric, TransAlta, and 17 other major market participants on the proposed changes to transmission planning. The AESO has stressed that optimal transmission planning works hand-in-glove with the implementation of Locational Marginal Pricing (LMP), which we’ve covered earlier.
