NV Energy (Sierra Pacific Power & Nevada Power) Solar Tariff FAQ
Should I choose NV Energy’s Flat Rate or Time-of-Use (TOU) rate with solar in Las Vegas?
If you have solar ONLY (no battery), stay on the Standard Flat Rate so midday exports net 1-for-1 against evening A/C within the month. If you have a large 28.6 kWh battery that can cover 100% of 6 PM–9 PM Summer Peak, TOU can unlock 36¢/kWh evening export credits.
Does NV Energy offer a battery storage incentive?
Yes, NV Energy’s Energy Storage Incentive program offers upfront rebates for residential batteries paired with Time-of-Use rates.
