New Mexico's largest electricity provider says it expects to add significant renewable energy resources to its portfolio in the coming years.
PNM released details of the resource plan it filed with state regulators Tuesday. The utility considered future changes in the cost and reliability of potential resources — from coal to solar and wind — in determining what should be included in the mix.
The plan outlines the utility's objectives for the next two decades and includes specific recommendations for the next few years.
PNM says it's still unclear how newly proposed rules for curbing carbon dioxide emissions will affect the utility's power sources in the future.
Environmental groups have been critical of PNM. They accuse the utility of leaving customers exposed to the costs of meeting environmental regulations.
