Staff for New Mexico’s utility regulators have recommended new rates for the state’s largest electric provider that would result in about a 3% decrease for residential customers instead of the 9.7% increase Public Service Co. of New Mexico was seeking. The Public Regulation Commission is expected to vote on the rate case after its hearing examiners issued their recommendation on Friday. Consumer advocates said they were pleased that New Mexican ratepayers would benefit from the recommendation, but argued even a larger reduction is warranted. The utility said they would file exceptions with the commission in an effort to recoup additional costs.
