Two of the three seats up for grabs on the state Public Regulation Commission will be decided with Tuesday's primary.
Incumbent Republican Pat Lyons is running unopposed in District 2, and there are no Democrats vying for his seat.
In District 4, incumbent Democrat Theresa Becenti-Aguilar is being challenged by Lynda Lovejoy and Edward Michael. No Republicans are running for the seat.
The PRC is one of New Mexico's most powerful and highest paid commissions. Its five members decide complex utility and telecommunication issues and regulate transportation, transmission and pipeline companies.
The election follows the announcement of new federal guidelines for greenhouse gas emissions from power plants. The commission will play a role in determining how New Mexico utilities adjust and how much of the costs are funneled to customers.
