Impacts of long-term temperature change and variability on electricity investments

Z. Khan, G. Iyer, et al.

This study by Zarrar Khan, Gokul Iyer, Pralit Patel, Son Kim, Mohamad Hejazi, Casey Burleyson, and Marshall Wise explores how long-term temperature variations affect electricity investments in the United States. Under high-emissions scenarios, temperature changes lead to notable increases in electricity demand and capital investments, emphasizing the critical need for thoughtful electric sector planning.

Abstract
This study investigates the impacts of long-term temperature change and variability on electricity investments. Using the United States as a case study, the researchers show that under a high-emissions scenario (SSP2-RCP 8.5), mean temperature changes increase annual electricity demand by 0.5–8%, while peak temperature changes drive increases in capital investments by 3–22%. These temperature-induced investments are highly sensitive to socioeconomic assumptions and spatial heterogeneity in fuel prices and capital stock characteristics, highlighting the need for a comprehensive approach to long-term electric sector planning.
