The peak demand charge allows NV Energy to impose a higher kilowatt (kW) rate for the time of day with the most energy use. Evidence presented by NV Energy suggests the daily demand charge “will lower power bills for nearly all of NV Energy’s customers…” according to a PUC news release. The shift, another effort to reduce the disparity between rooftop solar and traditional customers, applies to homeowners who install rooftop solar after Oct. 1 of this year. In 2024, NV Energy served roughly 505,000 non-solar residential customers and 105,000 rooftop solar customers, according to a federal regulatory filing. Rooftop solar customers “would be the third-largest customer class, behind single family residential and multifamily residential,” says Chairez.
