HOUSTON (Reuters) -The state of Texas' power-grid operator on Friday called on residents to cut their electricity use this weekend after six generating plants fell offline in a heat wave.

Record temperatures have pushed up demand for air conditioning, contributing to soaring wholesale prices this week. The call for residents to conserve came after prices soared to more than $4,000 per megawatt hour (MWH) in Houston briefly on Friday afternoon, from less than $6 MWH earlier.

The Electric Reliability Council of Texas (ERCOT) said six generation plants, providing 2,900 megawatts (MW), tripped offline on Friday afternoon. All of the grid's generation facilities had resumed operation, Interim ERCOT Chief Executive Brad Jones said in a revised statement.

"We're asking Texans to conserve power when they can," Jones said in a statement, asking residents to push up thermostats to 78-degrees Fahrenheit or above (25.5 Celsius) and not run power-consuming appliances during peak hours through the weekend.
