The path forward: ensuring resource adequacy central to 2021 priorities

The province’s electricity landscape is changing – and fast. After a period of robust supply, a number of factors – including expiring contracts, nuclear refurbishments and retirements, and growing demand – will create a growing capacity gap in the province over the second half of the decade. Against this backdrop, the IESO has established clear priorities to enable Ontario to continue to meet system needs cost-effectively and reliably, while laying the foundation for future change.
