New Mexico Hits 80% Carbon-Free Power in Just 5 Years

While most of the country watched electricity bills soar by 32% over the past five years, New Mexico quietly pulled off something remarkable. The state's largest utility transformed its power supply from dirty to clean without breaking customers' budgets.

The Public Service Company of New Mexico delivered 80% carbon-free electricity in 2025, a stunning reversal from 2021 when coal and gas powered nearly 80% of the grid. Solar panels now run air conditioners during scorching days, batteries store sunshine for evenings, and wind turbines spin through the night.

The catalyst was New Mexico's 2019 Energy Transition Act, which set ambitious renewable energy targets. But Laurie Williams, PNM's senior vice president, says the shift runs deeper than legal requirements. "We've understood more and more about climate and the impacts of traditional fossil fuels," she explained after 34 years with the company. "We've got to be part of solving the problem."

When PNM closed its massive San Juan coal plant in 2022, the company replaced every watt with renewables. The state set aside money to retrain displaced workers, exceeding its goal by retraining 2,800 people instead of the targeted 2,000.

Native American communities, many of whom worked at the coal operations, received dedicated funding for sustainable agriculture, new solar projects, and direct payments to displaced workers. Every tribe near a closing fossil fuel plant gets a seat at the table deciding how transition funds get spent.

Homeowners joined the movement too. Small-scale solar installations more than doubled since 2020, with over 13,000 PNM customers now sporting rooftop panels. Those without suitable roofs can buy shares in community solar farms, with 16 projects running and 31 more planned.

The Ripple Effect

New Mexico's success offers a blueprint other states desperately need. While national residential electricity prices jumped 32% from 2021 to 2026, New Mexico's rose just 7%. Households now pay $0.14 per kilowatt-hour compared to the national average of $0.18, keeping bills among the lowest in America.

The state also cracked a problem plaguing clean energy everywhere: grid connection delays. New Mexico earned the only "A" grade nationwide for interconnection policies by creating quick approval processes, low connection fees, and transparent reporting. Projects that wait years elsewhere plug in fast here.

Williams sees the transformation as more than environmental victory. New Mexico's economy leans heavily on oil and gas, but vast renewable resources offer new opportunities. "It feels like there is a chance to diversify the economy here in a way that could be really meaningful for the citizens and for the future of the state," she said.

PNM plans to hit 100% zero-carbon electricity by 2040, five years ahead of the state's deadline. The biggest math problem on the planet, as Williams calls it, is getting solved one sunny, windy day at a time in the Land of Enchantment.
