Pre-Engagement - Phase II: Large Load Integration

Important Dates and Materials

Purpose

The AESO rolled out Phase I of the Large Load Integration Program on June 4, 2025. Phase I included a 1,200 MW interim large load connection limit and a process for allocating that load among qualified project developers.

Phase II of the Large Load Integration Program will explore the changes necessary to create the long-term framework for large loads (including data centres) across the AESO’s mandate, including connections, planning, operations, markets, tariff and reliability.

The design of Phase II engagement is still in development and requires careful planning and coordination. To help shape its scope and direction, we are seeking stakeholder input on:

  • key questions and related topics to address; and
  • structure and timing, considering the interdependencies with other engagements.

See pages 3 and 4 of the latest Data Centre Update for the relevant information to complete the survey below.
