How climate change, new technology are shaping the future of extremes in peak power demand

A closer look at How climate change, new technology are shaping the future of extremes in peak power demand

What this article reports

A University of Michigan-led study models how extremes in peak electricity demand in U.S. buildings may evolve from 2020 to 2060, focusing on heating and cooling.

The researchers examined effects of climate change and technology diffusion (notably insulation and heat pumps) and published results in Proceedings of the National Academy of Sciences.

What the study actually did and found

The team used machine learning to model demand across 183 U.S. counties under four climate scenarios and 18 technology diffusion pathways, including cases with only climate change, only tech diffusion, and both combined.

Key reported outcomes: with only climate change, extreme peak demand rises 3%-9% everywhere except the Northwest (which shows a 3% decrease). With only technology diffusion, heat pump adoption increases peak demands by 60%-104% in cold regions and about 15% in temperate regions, while hot regions like Texas and California see decreases. Combined effects are more complex because warming can improve heat pump efficiency in winter.

Who might find this useful

The forecasts and scenario comparisons are aimed at utilities, policymakers, researchers, and grid professionals who need to plan for reliability under extreme demand conditions.

The study is also relevant for people interested in how heat pump adoption and insulation trends interact with changing temperatures to affect electric load extremes.

Questions people ask about How climate change, new technology are shaping the future of extremes in peak power demand

Does the study say climate change or technology will matter more?

The study reports that tech diffusion may have a larger impact than climate change on peak demand in many regions, but it also emphasizes that climate change remains an important source of risk and uncertainty.

What technology did the researchers focus on?

They focused on insulation and heat pumps and how broader adoption of those technologies changes extreme peak electricity demand.

Who conducted and supported the research?

The study was led by University of Michigan researchers with collaborators at MIT and Cornell and was supported in part by the U.S. National Science Foundation and the U-M Graham Sustainability Institute.
