Cases Before the New Mexico Public Regulation Commission

NMPRC Case No. 21-00267-UT: 2021 Rate Case

Notice to NMGC Customers

On December 13, 2021, New Mexico Gas Company submitted a request to the New Mexico Public Regulation Commission for a rate increase in 2023 to allow recovery of planned investments by the Company, and for the recovery of increasing operating costs. 

The request to the Public Regulation Commission, if approved in the second half of next year, would result in an average-use residential customer paying an additional $5.63 on an average monthly bill. This represents a 9.1% increase on that average monthly bill. Actual increases for each customer would depend on their actual usage. If approved, the requested new rates are anticipated to take effect in January 2023. The requested increase is for the Company’s services and does not reflect increased costs of natural gas. The cost of the gas delivered by New Mexico Gas Company is passed through to customers, at cost and without markup.

The requested rate change reflects a revenue increase of approximately $40.7 million compared to the Company’s current forecast for cost-of-service revenues in 2023. 

Much of the requested increase is related to the Company’s ongoing investments for its pipeline integrity program, cybersecurity programs, maintenance to ensure the reliability of its statewide system, customer service and technology, and initiatives to reduce greenhouse gas emissions, including some of the cost of a pilot project where hydrogen will be blended with natural gas. The request also addresses increasing operating costs resulting from inflation and requirements from various regulatory agencies regarding system operations.

Integrated Resource Plan

NMGC hosted five Integrated Resource Plan public advisory meetings throughout New Mexico in 2019 and early-2020. These meetings were hosted in Albuquerque, Santa Fe and our offices in Anthony, Roswell and Farmington to receive public input, feedback and ask questions about our company-plans.

Our Integrated Resource Plan, that is required by the NMPRC, is a four-year resource and system planning report developed with consideration from the public advisory meetings. The public advisory meetings and subsequent plan provides information on load forecasts, evaluation of existing gas supply and customer demand, identification of resource options, examination of price volatility and general attributes of potential resources, and modeling and risk assumptions leading to the development of a cost-effective portfolio of gas utility resources. See below for our slide deck which was presented at the public advisory meetings, the applicalbe IRP rule and the plan.

NMGC offers a host of cost-effective energy efficiency programs approved by the NMPRC. The program year for these offerings begins on April 1 and ends on March 31 each year. Annually, we file with the PRC both a Measurement and Verification Report and an Energy Efficiency Program Annual Report.
