———————————————————-

New Mexico’s 2026 legislative session moved fast, and for clean energy and climate policy the results were mostly disappointing. The session’s signature climate proposal, Clear Horizons (SB18), failed on the Senate floor. Other priorities tied to affordability, grid reliability, and responsible planning for rapid load growth also fell short in the compressed timeline.

At the Southwest Energy Efficiency Project (SWEEP), we came into the session focused on practical policies that help New Mexico manage new electricity demand without driving up bills or backsliding on climate progress. That meant supporting Clear Horizons as a durable, statewide planning framework, pushing for basic oversight of large private power systems tied to data centers, and advancing utility modernization tools that help reduce peak demand and keep system costs in check.

New Mexico is at an inflection point: we’re facing rapid load growth and real affordability pressures at the same time we’re trying to stay on track with climate goals. This session delivered an important step forward on industrial decarbonization, but we still need to finish the job on emissions targets and the utility reforms that help manage peak demand, protect ratepayers, and keep new large loads from driving the wrong outcomes.

A meaningful win: Industrial decarbonization and low-carbon materials (HB153)

In a session with more missed opportunities than wins, one major policy did make it across the finish line. SWEEP supported Representative Meredith Dixon and coalition partners, led by the Natural Resources Defense Council, in the successful push to pass HB153, an industrial decarbonization and low-carbon materials package, which is now awaiting the Governor’s signature. 

HB153 is designed to accelerate both the supply and demand for lower-carbon construction materials by:

• Helping projects buy low-carbon materials when cost is a barrier.
• Expanding consistent, comparable emissions information for purchasers.
• Supporting in-state manufacturers with tools to invest in lower-carbon production and compete in markets that increasingly require verified low-carbon materials.

Why this matters: construction materials and industrial products are a significant source of climate pollution, and procurement standards are changing quickly. HB153 helps New Mexico manufacturers and builders prepare for that reality, while supporting climate goals and economic competitiveness.

What fell short: Clear Horizons, data center safeguards, and peak-demand solutions

Clear Horizons (SB18)

Clear Horizons was the session’s signature climate proposal. It would have codified New Mexico’s statewide emissions reduction targets in statute, creating a clearer long-term framework for planning and accountability. SWEEP supported the bill alongside coalition partners, but it failed on the Senate floor.

Microgrid oversight and data center safeguards (SB235)

In addition, SWEEP joined a broad coalition supporting microgrid oversight (SB235) protections for large private power systems tied to data centers. SB235 would have put qualifying microgrids under New Mexico’s Public Regulation Commission (PRC) oversight and required them to meet a clean energy portfolio standard on the same timeline New Mexico already applies to utilities, along with annual reporting on energy generation and water use. The bill also included explicit protections to prevent utility rate increases to cover microgrid infrastructure development. SB235 passed the Senate but did not advance in the House before the session ended.

Two utility modernization bills that advanced, but did not reach final passage

Virtual power plants (HB 311)

SWEEP supported HB311 because virtual power plants can be a lower-cost reliability resource that pays customers for verified performance from technologies many households and businesses already use, such as smart thermostats, managed electric vehicle charging, and batteries. The bill cleared its first House committee, but did not advance further before adjournment.

Avoided greenhouse gas emissions in utility cost tests (HB254)

SWEEP supported HB254 to modernize how cost-effectiveness is evaluated for utility efficiency and load management programs. The bill would have allowed the PRC to incorporate the value of avoided greenhouse gas emissions into statutory cost-effectiveness tests. Developed with partners including El Paso Electric and Western Resource Advocates, HB254 passed the House unanimously but did not advance in the Senate before the session ended.

A transition moment for New Mexico policy

This was the final regular session of term-limited Governor Michelle Lujan Grisham, which makes this a natural transition point for long-term policy planning. Energy policy is getting more complex, and the stakes for affordability, reliability, and emissions outcomes are getting higher as new large loads and electrification reshape the grid.

Lawmakers also advanced HJR5, a proposed constitutional amendment that would allow legislative compensation. New Mexico is currently the only state where legislators receive no base salary for their service; lawmakers receive per diem and mileage reimbursements while the Legislature is in session and for interim committee work. If voters approve HJR5, it would allow legislative compensation tied to New Mexico’s median household income. SWEEP views this as a constructive step toward professionalizing legislative service and broadening who is able to serve, which can strengthen policymaking capacity over time.

What we do next

The session ended, but the work did not. SWEEP will continue working with coalition partners, state agencies, utilities, and regulators throughout the interim to:

• Keep New Mexico moving toward its emissions reduction goals through practical implementation and utility planning work.
• Advance utility reforms and programs that reduce peak demand, strengthen reliability, and keep bills manageable.
• Ensure large private power systems and data center-related infrastructure meet basic standards for transparency and consumer protection.

We look forward to working with legislators, stakeholders, and the next administration to advance durable solutions that keep bills manageable, strengthen reliability, and support responsible economic growth in the years ahead.
