Las Cruces owns its gas, water, wastewater, and trash services outright — a genuine local counterexample to the investor-owned model, and the reason the city's gas bills aren't set in Austin or Tulsa. Rate changes are argued at the Utilities Board and city council, in town, on the record.
It's also proof that public ownership isn't the whole story for a household's utility costs: the electric bill in every Las Cruces home still goes to private-equity–owned El Paso Electric, which is currently asking New Mexico regulators for a $70.4 million increase. The same house pays a municipal utility and a JPMorgan-advised fund every month.
One quirk worth knowing: your yearly sewer rate is set by your metered water use during the winter months — conserve water in December through February and you pay a lower wastewater rate all year.
