Data center demand strains rural New Mexico grid, alarms Los Lunas residents

A surge of data-center power demand near Los Lunas is forcing Valencia County residents to confront a basic question: how much new load can rural New Mexico carry before the costs show up on monthly bills, local reliability and future growth decisions for small businesses.

State energy officials have warned for months that data centers are driving multi-gigawatt electricity demand and that the load can be hard to forecast. The New Mexico Energy, Minerals and Natural Resources Department says that kind of growth can overwhelm transmission and interconnection capacity, with possible consequences that include higher prices for other rate classes, grid instability and planning problems for utilities and regulators.

That warning is landing hard in Los Lunas and Belen, where residents are calling for stricter limits on large new users. Their concern is not just about one project. It is about whether a rural grid built to serve homes, farms and small businesses can absorb giant, fast-growing industrial loads without passing more costs on to everyone else.

The New Mexico Public Regulation Commission says its utility division is responsible for making sure utility service stays “fair, just and reasonable” and for representing the public interest in utility matters. That matters in Valencia County because Public Service Company of New Mexico serves more than 550,000 residential and business customers in Greater Albuquerque, Rio Rancho, Los Lunas, Belen and other communities. When a major new user comes onto that system, the ripple effects do not stop at the edge of a data center campus.

Meta’s Los Lunas footprint has been central to the debate. The company chose Los Lunas for a data center in 2016, and the village approved a major expansion in March 2021. PNM has since filed an application seeking approval for additional renewable energy resources to support the expansion load for Meta’s data center near Los Lunas. In its filings, PNM says those tariff documents are subject to PRC review and approval.

The political pressure has been building as well. At a 2024 legislative hearing, Rep. Christine Chandler warned that AI uses a lot of power and water and said New Mexico communities may be forced to share electricity with “a gigantic, mammoth facility.” A 2025 legislative presentation went further, saying some states could see data centers consume more than 20% of total electricity by 2030. It cited federal data showing server energy use rising from 30 terawatt-hours in 2014 to 100 terawatt-hours in 2023, while GPU-accelerated AI server energy use jumped from under 2 terawatt-hours in 2017 to more than 40 terawatt-hours in 2023.

For Los Lunas and Belen, the fight is no longer theoretical. The region now sits at the center of a statewide test: whether New Mexico can modernize its grid, attract investment and still protect ratepayers from the strain of the next giant load.
