Executive Summary

Ontario’s Long-Term Energy Plan (LTEP) places significant reliance upon Distributed Energy Resources (DER) consisting of renewables and storage to address a gap in the province’s electricity supply mix that will emerge over the next fifteen years. This report examines the economics of meeting this supply gap with renewables-based (solar and wind) DER and how the intermittent output of these variable generation sources interacts with storage to undermine those economics.
