Three regional electricity transmission organizations in the United States, including PJM, ERCOT, and SWPP, set new hourly loading records this summer. These records occurred due to extreme heat and increased cooling demand, especially during heat waves this season.
Record Details
According to data reported in the EIA-930 form, hourly loading in PJM reached 120,000 megawatts, in ERCOT it reached 73,000 megawatts, and in SWPP it reached 40,000 megawatts. These records indicate peak demand at times when temperatures were at their highest, leading to increased energy needs for cooling.

Impact of Heat on Energy Consumption
While these organizations set new records, two other organizations, namely CAISO and ISO-NE, also approached 2 percent of their previous records. Additionally, NYISO was only 3 percent and MISO 4 percent away from their previous records. This increase in loading reflects the direct impact of heat on energy consumption patterns in the United States.
The data collected from the EIA-930 form is recognized as the best values at the time of reporting, but reporting issues may affect the quality of this data. Moreover, the data published by each balancing entity may differ from the EIA-930 form data.
Consequences and Analyses
These records not only represent increased demand during heat but may also lead to greater challenges in energy supply and load management. Especially as climate change and global warming increasingly impact energy consumption patterns, this highlights the need for careful planning and optimization of infrastructure.
Ultimately, these records could influence energy policies and economic decision-making, particularly regarding investment in renewable energy resources and energy transmission infrastructure.
