(Reuters] – Texas will continue to be tested by the heatwave this week, with record monthly demand on Tuesday. Monday’s cooler weather has kept use below a new low.

Friday saw power plant problems cause prices to rise to over $4,000. Per megawatt hour (MWh) on Friday. The grid operator requested that consumers conserve their energy.

Electric Reliability Council of Texas – which oversees most of Texas’ grid, reported that the conditions in Texas were good early Tuesday.

AccuWeather predicted that Houston would see high temperatures of 94°F (34.4 Celsius) Tuesday, before dropping to the lower to middle 90s the remainder of the week. This compares to a typical high temperature of 86 for this time of the year.

Houston saw a Monday record high of 93 degrees, well below forecasts.

Extreme weather brings back memories of the February 2021 freeze in Texas that saw millions of people without heat, power or water for several days. ERCOT was scrambling to stop a collapse of their grid after a large number of generators were shut down.

ERCOT predicted that Tuesday’s demand would be 71.5223 megawatts, (MW), breaking the May 9th grid record of 70.703 MW. In August 2019, the all-time record of 74 820 MW was reached.

On a normal day one megawatt could power approximately 1000 homes across the USA, while only around 200 houses in Texas can be powered by it on a hot Texas summer day.

ERCOT reported Monday that economic growth will continue to boost peak demand, which is expected to reach 77.317MW in the summer. Grid expects that it will have around 91.392 MW of energy resources in order to provide power for this summer.

Prices at ERCOT North, which also includes Dallas, dropped to $79 per MWh on Tuesday after an 11-month peak of $246.
