IESO Releases 2025 Annual Planning Outlook  Demand Forecast

Overview

Earlier today, the Independent Electricity System Operator (IESO) released one component of the agency’s Annual Planning Outlook (APO), the 2025 Demand Forecast. The next APO is anticipated for Q1 2025 and will present additional forecasts on electricity demand, the supply and transmission outlook, and system needs for 2026-2050 while identifying what steps need to be taken to address emerging shortfalls.

The early release of an updated demand forecast is to ensure the industry is aware of the rapidly changing system based on a growing queue of load connections and the related increasing demand for electricity in Ontario.

Canada’s Nuclear Renaissance, Continued

Canada unveiled its first-ever sectorwide Nuclear Energy Strategy, setting concrete build-out targets: up to 10 new domestic reactors by 2040, four new export markets by 2040, across a four-pillar plan covering domestic builds, exports, fuel/waste management, and fission/fusion innovation. The strategy stays technology-agnostic between CANDU, AP1000, and Gen IV designs, leans on existing financing tools rather than new funding (with a dedicated financing policy due next April), and frames nuclear as central to doubling Canada's grid capacity and capturing global export demand as countries move away from Russian supply chains.
