The utility says energy rates should decline throughout the year. Here’s why. : In an email to ratepayers on Wednesday, NV Energy CEO Doug Cannon said customers should see some of the electric rates in their bills fall throughout the year. The average customer’s electric bill in Southern Nevada should be 15 percent lower at the end of 2024 compared to the end of 2023, he said. The promised reduction was attributed to a continued decline in natural gas prices.
