Electricity demand in the PJM Interconnection and ISO New England (two regional grid operators covering the Northeast United States) reached multiyear highs on June 23 and June 24, respectively. Electricity demand increased significantly due to a heat wave that affected most of the Eastern United States this week.

PJM Interconnection
Electricity load in the PJM Interconnection, the largest wholesale electricity market in the country, peaked at 160,560 megawatts (MW) on Monday, June 23, between 5:00 p.m. and 6:00 p.m. according to data from our Hourly Electric Grid Monitor. The load on the grid surpassed PJM’s seasonal peak load forecast of 154,000 MW but remained below the record load of 165,563 MW in 2006 (PJM has expanded numerous times, and this data point is based on PJM’s current footprint). PJM’s footprint includes 13 states

In our Annual Energy Outlook 2025 (AEO2025) Reference case, we project the electricity consumed for commercial computing will increase faster than any other end use in buildings. Computing accounted for an estimated 8% of commercial sector electricity consumption in 2024 and grows to 20% by 2050. Ultimately, more electricity could be consumed by computing than for any other end use in the commercial sector, including lighting, space cooling, and ventilation.

We expect commercial computing growth will outpace computing efficiency improvements which, in the past, have moderated the growth in electricity consumption associated with computers. Commercial computing electricity demand growth is significant enough in our projections to contribute to a reversal in the trend in declining commercial electricity intensity, as measured in kilowatthours consumed per square foot. Many of our assumptions about future
