July 9, 2025 | Consultants Selected

Benefit of Service Study | 1-on-1 Confidential Interviews July- Aug, 2025

We have selected a consortium of consultants to complete the Benefit of Service (BoS) study. We are excited to announce that Boost Energy Ventures, Energex Partners, and Power Team Consulting (BoS Consortium) will be completing this first of a kind study for Alberta’s electricity industry.

The BoS Consortium will perform a quantitative and qualitative analysis to help answer: “What is the value of service from transmission connectivity in Alberta?”

They will study 13 archetypes in grid-connected and off-grid configurations. View the summary of their methodology and archetypes.

They will be directly engaging with electricity consumers to gather information on:

  • the value of grid service,
  • the impacts to consumers when it is interrupted (value of lost load), and
  • how they make decisions related to their electricity needs.
The BoS Consortium representatives will be reaching out to targeted consumers in July and August, 2025. If you have comments on their methodology, are part of one of the economic sectors identified and would like to participate in the one-on-one confidential interviews with the BoS Consortium throughout July and August, please contact ISOTariffRedesign@aeso.ca.
