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.

Future Energy Resources: Resource Planning

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 results in an resource roadmap for PNM and documents the actions required to achieve the plan's objectives over the next four years.
