Aztec electric department flags potential multimillion‑dollar resource adequacy costs; staff will not extend contract with Guzman Energy to 2035
Summary
City electric staff warned that proposed resource adequacy obligations tied to the Southwest Power Pool could require about 8,000,000 kWh in coverage and cited steep cost implications; staff signaled they will not renew their Guzman Energy contract beyond 2030 and will explore alternatives at a March 24 workshop.
Aztec electric-department leadership warned the City Commission that participation in the regional transmission organization and evolving resource-adequacy requirements could impose substantial new costs on the city's utility operations.
John (speaker 8), speaking for the electric department, said staff are still gathering information about how the Southwest Power Pool and Western Area Power Administration will allocate resource-adequacy responsibilities. He estimated the city's obligation could be on the order of 8,000,000 kilowatt-hours and described proposed percentages of approximately 16% in summer and 32% in winter for resource coverage. Because of those projected cost increases, he told commissioners the city does not intend to extend its Guzman Energy contract beyond 2030 to 2035.
Staff discussed potential responses including developer- or supplier-built solar-plus-battery installations (roughly 2 megawatts of solar backed by 4 megawatt-hours of batteries), or using on-site standby generators that Guzman Energy could operate when needed. John said a workshop is scheduled for March 24 to review options and that a formal decision about contract changes will be brought to the commission.
The commission did not take a final public action on contracting in this meeting; instead staff were asked to present details and options at the upcoming workshop.
