The devastating Texas blackouts provided a fresh reminder of the challenge of meeting electric demand in unusually cold weather. These threats are expected to increase as extreme weather events become more frequent and as more home heating is electrified. A new ACEEE report will assess the future of “winter peaks” in electricity use and show how implementing energy efficiency and other demand-side measures could mitigate the threat, even in cold regions of the country. ACEEE researchers will present the findings and an expert panel will discuss recommendations for policymakers, grid planners, regulators, utilities, and efficiency program administrators.
