 capability. Freezing tempetures resulted in the total failure of both of the city's natural gas power plants, resulting in rolling blackouts across the city. The loss of power had a ripple effect across the region, as the power failure left water and gas utility without the power needed to operate pumps to move the water and natural gas to customers. This resulted in the complete cancellation of activities at all area independent school districts and institutions of higher education on Wednesday, Thursday, Friday, and the following Monday. In total, nearly 200,000 El Paso Electric customers have gone without power at some point as a result of the storm, while 1,200 Texas Gas Service customers have gone without gas. Over 157 water main breaks due to cold temperatures have been reported to the El Paso Water Utilities, which when combined with the frozen water pumping equipment and abnormally high demand for water left El Paso water reservoirs dangerously low. Stage 2 mandatory water restrictions, which permit the use of water for drinking only were, were implemented Monday night as the water utility worked to raise the water levels in the reservoirs, and on Wednesday the water restrictions were lifted. That same Wednesday it was announced that Federal and State officials would conduct an investigation into El Paso Electric as a result of the spectacular failure of the utility during the blizzard.
