ERCOT manages electric power to more than 26 million Texas customers and represents 90% of the state's electric load, according to the company.
On Monday ERCOT asked customers to voluntarily raise thermostats a degree or two, turn off lights, avoid using ovens, washing machines and dryers, and unplug appliances if possible during the hours of 2-8 pm.
According to ERCOT, a heatwave along with very low winds is causing the latest conservation alert. In a press release it said:
"Wind generation is currently generating significantly less than what it historically generated in this time period. Current projections show wind generation coming in less than 10 percent of its capacity."ERCOT was forced to take emergency action two days after it issued a conservation alert.
Comment: Wind turbines consistently prove to be a costly investment with unreliability when most needed. Turbines must have wind to run and quit if it exceeds 50 MPH.
