Long-Term Transmission Plan
The AESO Long-Term Transmission Plan (LTP), published every two years, presents a 20-year plan for developing Alberta's transmission system.
The plan outlines how the AESO aims to meet Alberta’s growing energy demands, support economic development, and ensure our grid operates safely, reliably and efficiently. It is a comprehensive roadmap that addresses the grid’s challenges and opportunities, guided by Alberta’s Electric Utilities Act and Transmission Regulation.
