Mexico's First Biomethane Plant Joins Clean Energy Registry

A groundbreaking renewable energy facility in Lagos de Moreno, Mexico, just earned a seal of approval that puts Mexican biomethane on the same trusted map as clean energy across North America.

Brimex Energy's renewable natural gas plant has become the first Mexican thermal energy project registered on the CleanCounts Registry, North America's largest clean energy tracking system. The registration, announced in September 2026 at both the Mexico Carbon Forum and the Renewable Energy Markets conference, means every unit of clean fuel the facility produces now carries verifiable proof that buyers and auditors recognize continent-wide.

The facility solves a powerful problem: what to do with massive amounts of organic waste from three industries that define the Altos de Jalisco region. Whey and milk byproducts from dairies, swine manure from pig farms, and vinasse from tequila distilleries all flow into three onsite anaerobic digesters. The resulting biogas powers generators that feed electricity into Mexico's commercial grid, and a portion gets upgraded into biomethane vehicle fuel.

Major food and beverage brands supply the waste streams, including tequila producers Teremana and Campo Azul, along with food companies Grupo Lala and Sigma Alimentos. What they once had to dispose of now becomes clean energy for their region.

Brimex holds Mexico's first federal permits for producing biomethane and, as of February 2026, for selling it commercially. The registry registration took the facility one step further after an independent engineering review by EcoEngineers found the operation met rigorous verification standards.

The Ripple Effect

The registration changes what Mexico's emerging biomethane market can offer the world. Before registry-grade tracking, proving that renewable fuel came from a specific Mexican facility required separate, often inconsistent documentation. Now, certificates issued through CleanCounts carry unique serial numbers that record the resource type, location, and production period, creating an auditable chain of custody from generation through final use.

CleanCounts issued its two billionth certificate in 2025 and processes more than 40 percent of all renewable energy certificates in North America. Its architecture prevents double counting, the problem where two parties claim credit for the same clean energy unit. Utilities and Fortune 500 companies across the United States and Canada already rely on this infrastructure for compliance and sustainability reporting.

For corporate buyers seeking verifiable renewable fuel from Mexico, the barrier just dropped significantly. The same system they trust for tracking solar power in Texas or wind energy in Ontario now confirms biomethane from Jalisco dairy barns and tequila distilleries.

Guillermo Chaim Serrano, Brimex Energy's CEO, built the plant to prove waste streams from Los Altos could provide regional clean energy. Brad Pleima, president of EcoEngineers, emphasized that certificates only work when backed by rigorous verification and ongoing audits.

Ben Gerber, CleanCounts president and CEO, calls registries "the accounting layer of decarbonization" that ensures Mexican biomethane gets measured once, claimed once, and trusted everywhere. His team expects Brimex to be the first of many Mexican projects as clean energy markets expand across the country.
