Ontario's Integrated Energy Plan Overview

This document is a report on Ontario's Integrated Energy Plan (IEP), released by the Government of Ontario on June 12, 2025. The IEP aims to establish a comprehensive policy strategy for energy planning and regulation in Ontario, focusing on four core principles: affordability, security, reliability, and clean energy. The report outlines the directives issued to the Ontario Energy Board (OEB) and the Independent Electricity System Operator (IESO), mandating their adherence to the IEP. Key components of the IEP include an Integrated Planning Framework, a Natural Gas Policy Statement, and a focus on Distributed Energy Resources (DERs). The plan emphasizes the importance of nuclear and hydroelectric resources, market design, and procurement reforms. Additionally, it highlights the role of Indigenous participation and low-carbon technologies in shaping Ontario's energy future. The IEP is supported by legislative instruments that enhance the Minister's powers and align planning frameworks to accelerate infrastructure development.
