Scope of the AUC’s inquiry

The inquiry is separated into two modules (Module A and Module B) to explore the key issues identified in the Alberta government’s order-in-council. Module A, which was considered in Proceeding 28501, explored the land impact issues identified in the Alberta government’s order-in-council. The Module A report is available here.

In Module B, the AUC has been directed to consider the impact the increasing growth of renewables has to both generation supply mix and electricity system reliability. The AUC is aware that the Alberta Electric System Operator (AESO) is undertaking complementary work relating to system reliability. The AUC intends to take the AESO’s work into account to support the inquiry.

The AUC has commissioned two expert reports as summarized below. The scope of work for each report is set out in detail in a separate letter.

Expert report Scope of report
  • Review and assess prior studies that evaluate the evolution of the Alberta electric system from a technical and/or economic perspective in order to inform reliability and affordability questions.
  • Following stakeholder engagement, development of a technical, simulation-based assessment of future wholesale market fundamentals under the current energy market design over the long term to evaluate future system reliability (e.g., resource adequacy) and consider electric utility bill impacts for retail customers.
Longview Communications & Public Affairs
  • Using targeted stakeholder engagement and other means, gauge current perception of Alberta’s power market by relevant generation developers (incumbent and non-incumbent) and sources of capital to review attractiveness of Alberta’s market structure, views on potential market structure changes, and appetite for merchant power risk.
  • Identify the drivers behind stakeholder perception of Alberta’s power market.
