PNM

The percentages (on the basis of KWh) of PNM’s generation of electricity, including Valencia, fueled by coal, nuclear fuel, and gas and oil, and the average costs to PNM of those fuels per MMBTU were as follows:

In 2025 and 2024, 57% and 48% of PNM’s generation was from wind and solar resources (including PPAs), which have no fuel cost. Due to locally available natural gas, the utilization of locally available coal deposits, and the generally adequate supply of nuclear fuel, PNM believes that adequate sources of fuel are available for its generating stations into the foreseeable future. PNM recovers substantially all of its fuel and purchased power costs through the FPPAC.

Coal

Four Corners obtains its coal requirements from a mine near the plant. The coal supply arrangement for Four Corners runs through July 6, 2031, and provides for pricing adjustments over its term based on economic indices. See Note 16 for additional information about PNM’s coal supply arrangements. See Note 17 for additional information about PNM’s SJGS Abandonment Application, PNM’s Four Corners Abandonment Application, and PNM’s IRP.

Natural Gas

The natural gas used as fuel for the electric generating plants is procured on the open market and delivered by third-party transportation providers. The supply of natural gas can be subject to disruptions due to extreme weather events and/or pipeline or facility outages. PNM has contracted for firm gas transmission capacity to minimize the potential for disruptions due to extreme weather events. Certain natural gas plants of PNM’s are generally used as peaking resources that are highly relied upon during seasonally high load periods and/or during periods of extreme weather, which also may be the times natural gas has the highest demand from other users.

Nuclear Fuel and Waste

PNM is one of several participants in PVNGS. The PVNGS participants are continually identifying their future nuclear fuel resource needs and negotiating arrangements to fill those needs. Additional needed supplies are covered through existing inventories or spot market transactions. The PVNGS participants have contracted for 77% of PVNGS’s requirements for uranium concentrates through 2026 and an average of 42% through 2031. For conversion services, 90% are contracted through

A - 7

2026 and an average of 68% through 2031. For enrichment services, 100% is contracted through 2026 and an average of 57% is contracted through 2028. For fuel assembly fabrication, 100% is contracted through 2027.

The Nuclear Waste Policy Act of 1982 required the DOE to begin to accept, transport, and dispose of spent nuclear fuel and high-level waste generated by the nation’s nuclear power plants by 1998. The DOE’s obligations are reflected in a contract with each nuclear power plant. The DOE failed to begin accepting spent nuclear fuel by 1998. APS (on behalf of itself and the other PVNGS participants) pursued legal actions for which settlements were reached. See Note 16 for information concerning these actions.

The DOE had planned to meet its disposal obligations by designing, licensing, constructing, and operating a permanent geologic repository at Yucca Mountain, Nevada. In March 2010, the DOE filed a motion to dismiss with prejudice its Yucca Mountain construction authorization application that was pending before the NRC. Several legal proceedings followed challenging DOE’s withdrawal of its Yucca Mountain construction authorization application. None of these lawsuits have been conclusively decided. However, the DC Circuit ordered the NRC to resume its review of the application. The results of the NRC’s review publications do not signal whether or when the NRC might authorize construction of the repository.

All spent nuclear fuel from PVNGS is being stored on-site. PVNGS has sufficient capacity at its on-site ISFSI to store all of the nuclear fuel that will be irradiated during the initial operating license periods, which end in December 2027. Additionally, PVNGS has sufficient capacity at its on-site ISFSI to store a portion of the fuel that will be irradiated during the extended license periods, which end in November 2047. If uncertainties regarding the U.S. government’s obligation to accept and store spent fuel are not favorably resolved, the PVNGS participants will evaluate alternative storage solutions. These may obviate the need to expand the ISFSI to accommodate all of the fuel that will be irradiated during the extended license periods.
