Energy Sources

A Commitment to Reliable, Affordable, and Environmentally Responsible Power

PNM is on a path to serve its customers 100% emissions-free electricity within the next two decades.  The company is focused on serving you with a resource mix that safely provides reliable, affordable, and environmentally responsible power. 

PNM Generation Portfolio

PNM owns a diverse mix of generation resources that powers our New Mexico customers and uses additional resources to serve electricity needs through power purchase agreements.

As a regulated electric utility, nearly all of our owned generation resources are dedicated to serving customers in our regulated jurisdictions. The New Mexico Public Regulation Commission is responsible for approving the addition of new generation resources, the time frame that those resources can come into service, and the time frame the resources can be recovered through retail rates.

PNM Generation Resources

  • Emissions-Free Energy
    • Wind
    • Solar
    • Geothermal
    • Nuclear
    • Energy Storage
  • Coal
  • Natural Gas

Capacity in electric generating facilities, which are owned, leased, or under Power Purchase Agreements, in commercial service as of December 31, 2019 is:

Future Energy Resources: Resource Planning

Solar Jicarilla 2 Jicarilla Nation 50 MW Mar. 2021
Solar Route 66 Cibola 50 MW Nov. 2021
Solar Jicarilla 1 Jicarilla Nation 50 MW Nov. 2021


Longer Term Resources

PNM conducts an Integrated Resource Plan (IRP) once every three years. The IRP identifies generation mixes that could supply energy needs over a 20-year period. The IRP is a public process that incorporates public meetings and inputs in the final plan.

The IRP requirements say that PNM should prefer resources that minimize environmental impacts when costs and services are equivalent.

The IRP results in an resource roadmap for the Company and more specifically documents the actions required to achieve the plan's objectives over the next four years.

On July 3, 2017, PNM filed the 2017 IRP with the New Mexico Public Regulation Commission. Analysis in the 2017 IRP shows a most cost-effective portfolio that would result in the following changes to PNM's generation resources:

  • Retire SJGS coal-fired Units 1 and 4 in 2022 (497 MW retail + 65 MW merchant) after the existing coal-supply agreement expires on June 30, 2022 (Units 2 and 3 were retired at the end of 2017),
  • Exit the 13% participation (200 MW) in Four Corners Power Plant when the existing coal-supply agreement expires in 2031, and
  • Acquire replacement power consisting of renewables, natural gas, and potentially energy storage.
