Non-Wires Alternatives Guide Posted for Regional Planning
June 1, 2023
A guide to how the IESO assesses non-wires alternatives (NWAs) during Integrated Regional Resource Plans (IRRPs) has now been posted on the Planning Information and Data webpage. The document summarizes various recent improvements made in recent years to better consider NWAs when developing an IRRP, including the process flow diagram, screening mechanism, hourly needs characterization, development of options and economic evaluation methodology.
More information on the engagement activities that supported the development of this guide can be found on the Distributed Energy Resources Roadmap webpage.
