Currently, a homeowner in Las Vegas using 2700 kilowatt hours in July would pay approximately $300 for the electricity (excepting taxes, etc.). If the California, Pacific Gas and Electric rate schedule E-1 and baseline zone X were applied to the same amount of electricity the charge would be approximately $1047. In certain part of California the charge would be still higher.
The California billionaire Thomas Steyer is trying to convince Nevada to copy the extreme energy policies of California. In hot Las Vegas, electricity consumption for air conditioning is sky high. The typical southern Nevada resident uses almost triple the amount of electricity that the typical California resident uses. With California policies, July bills of $1000+ would become normal. A Tom Steyer proposition to lock Nevada into California style solar energy will be on the 2020 ballot.
California electricity is expensive because they insist on using very expensive solar energy. As part of their green policies they charge a higher rate to big users of electricity. If you are a typical resident of Las Vegas, you are a big user according to California thinking
