PJM, ERCOT and the Southwest Power Pool (SWPP) each set a record for hourly peak load during summer 2026, the U.S. Energy Information Administration reported. Based on Form EIA-930 data, PJM reached 162.6 gigawatts (GW) on July 2, 1.3% above its previous 160.6-GW record; ERCOT reached 91.1 GW on July 22, 6.5% above its prior 85.5-GW record; and SWPP reached 58.0 GW on July 27, 3.5% above its previous 56.0-GW record.

These are separate regional transmission-organization peaks, not a single national electricity-demand measure. EIA says the figures are reported through Form EIA-930 and represent each day's highest hourly load. The agency said most of the peaks occurred during regional heat waves, when cooling demand increased.

## Data

### Regional grid operators’ summer 2026 peak loads

Highest hourly loads reported by EIA from Form EIA-930 data, compared with prior records. These are not national totals.

Methodology: EIA reports the highest hourly load for each day. GW values apply to each regional operator’s service area; percentage changes are EIA’s comparisons with prior records.

| Regional operator | 2026 peak date | Hourly peak load | Pre-2026 record | Increase over prior record |
|---|---|---|---|---|
| PJM | July 2, 2026 | 162.6 | 160.6 | 1.3 |
| ERCOT | July 22, 2026 | 91.1 | 85.5 | 6.5 |
| Southwest Power Pool (SWPP) | July 27, 2026 | 58.0 | 56.0 | 3.5 |
