Power producer urges conservation as Vegas hits record high July 11, 2021 GMT LAS VEGAS (AP) — As Las Vegas hit record-high temperatures, Nevada’s largest power provider urged customers to conserve electricity Saturday and Sunday evenings because of extreme heat and wildfires affecting transmission lines in Western states. Customers should turn off lights and pool pumps, unplug appliances not in use and avoid using large appliances such as dishwashers from 6-9 p.m. each day, NV Energy said Saturday in a statement. “Conservation is the best way to reduce strain on the local power grid.” At 5:12 p.m. Saturday, temperatures at Las Vegas’ McCarran International Airport hit a record high of 117 Fahrenheit (47 Celsius), the National Weather Service said.
