ERCOT 7月22日小时峰值负荷达91.1吉瓦，创纪录

Hourly peak load in ERCOT set a new record, exceeding 91 GW on July 22

AI 导读

美国能源信息署称，得州电力可靠性委员会（ERCOT）7月22日小时峰值负荷达到91.1吉瓦，创下新纪录，比此前2023年8月10日的85.5吉瓦高6%。该峰值出现在中部时间下午6时，主要由天然气（48%）和太阳能（32%）发电满足；高峰期间得州正经历热浪。

推荐理由

ERCOT创纪录峰值负荷及天然气、太阳能供电占比，为观察得州高温期间的电力需求与发电结构提供数据。

ERCOT hourly peak load

Data source: U.S. Energy Information Administration, EIA-930, Hourly Electric Grid Monitor
Note: ERCOT=Electric Reliability Council of Texas

Hourly peak load in the Electric Reliability Council of Texas (ERCOT), the regional transmission organization serving most of Texas, reached a record 91.1 gigawatts (GW) on July 22, 2026, according to data reported to us for our Hourly Electric Grid Monitor.

Set against the backdrop of growing U.S. electricity demand:

The July 22 peak was 6% greater than the previous peak of 85.5 GW, set on August 10, 2023 according to ERCOT.
The July 22 peak occurred at 6:00 p.m. CT and was primarily met with generation from natural gas (48%) and solar (32%) resources according to data reported to us.
The peak occurred during a heat wave and could be surpassed again this summer, especially if Texas experiences another heat wave. Electricity demand and generation in ERCOT have been increasing in Texas.
More recently, electricity demand in the Southwest Power Pool reached a record 57.9 GW on July 27 at 5:00 p.m. CT.
In regions with increasing electricity demand and generation, periods of high demand, such as heat waves, are likely to continue to set records.
