HOUSTON (Reuters) - Texas power use peaked on Monday afternoon at a higher level than in any previous June even as the state urged consumers to limit appliance use to avoid straining power plants, as much of the state broiled under triple-digit temperatures.
Power demand reached 65,047 megawatts in the hour between 4 p.m. and 5 p.m. CDT (2200 GMT), surpassing the June record of 63,102 MW set last year, according to preliminary grid data.
Real-time power prices briefly exceeded $100 per megawatt-hour Monday afternoon and next-day power prices in the state traded between $165 and $175 per megawatt-hour, down several dollars from Monday's trades.
The extreme heat hit Sunday when the mercury hit 100 degrees Fahrenheit (38 Celsius) in Houston, San Antonio and Dallas, the three biggest cities in the Lone Star State, prompting residents to crank up air conditioners. Triple-digit highs are forecast for several more days this week, with some high enough to set records, AccuWeather.com forecast.
