Construction Program and Jointly-Owned Electric Generating Plants
Construction Program and Jointly-Owned Electric Generating Plants
PNMR’s construction expenditures for 2012 were $308.9 million. PNM’s construction expenditures for 2012 were $196.8 million, including expenditures on jointly-owned projects. TNMP does not participate in the ownership or operation of any generating plants, but incurred construction expenditures of $93.0 million during 2012.
 
Joint Projects

Under the agreements for the jointly-owned projects, PNM has an undivided interest in each asset and liability of the project and records its pro-rata share of each item in the corresponding asset and liability account on PNM’s Consolidated Balance Sheets. Likewise, PNM records its pro-rata share of each item of operating and maintenance expenses for its jointly-owned plants within the corresponding operating expense account in its Consolidated Statements of Earnings. PNM is responsible for financing its share of the capital and operating costs of the joint projects.
At December 31, 2012, PNM’s interests and investments in jointly-owned generating facilities are:

Includes interest in PVNGS Unit 3, interest in common facilities for all PVNGS units, and owned interests in PVNGS Units 1 and 2.
San Juan Generating Station
PNM operates and jointly owns the SJGS. SJGS Units 1 and 2 are owned on a 50% shared basis with Tucson. SJGS Unit 3 is owned 50% by PNM, 41.8% by SCPPA, and 8.2% by Tri-State. SJGS Unit 4 is owned 38.457% by PNM, 28.8% by M-S-R Public Power Agency, 10.04% by the City of Anaheim, California, 8.475% by the City of Farmington, New Mexico, 7.2% by the County of Los Alamos, New Mexico, and 7.028% by UAMPS. See Note 16 for additional information about SJGS.
Palo Verde Nuclear Generating Station
PNM is a participant in the three units of PVNGS, also known as the Arizona Nuclear Power Project, with APS (the operating agent), SRP, EPE, SCE, SCPPA, and The Department of Water and Power of the City of Los Angeles. PNM has a 10.2% undivided interest in PVNGS, with portions of its interests in Units 1 and 2 held under leases. See Note 7 for additional information concerning the PVNGS leases.
Operation of each of the three PVNGS units requires an operating license from the NRC. The NRC issued full power operating licenses for Unit 1 in June 1985, Unit 2 in April 1986, and Unit 3 in November 1987. The full power operating licenses were originally for a period of 40 years and authorize APS, as operating agent for PVNGS, to operate the three PVNGS units. On April 21, 2011, the NRC approved extensions in the operating licenses for the plants for 20 years through June 2045 for Unit 1, April 2046 for Unit 2, and November 2047 for Unit 3. In April 2010, APS entered into a Municipal Effluent Purchase and Sale Agreement that provides effluent water rights necessary for cooling purposes at PVNGS through 2050.
Four Corners Power Plant
PNM is a participant in two units of Four Corners with APS (the operating agent), EPE, SRP, SCE, and Tucson. PNM has a 13.0% undivided interest in Units 4 and 5 of Four Corners. The Four Corners plant site is leased from the Navajo Nation and is also subject to an easement from the federal government. APS, on behalf of the Four Corners participants, has negotiated amendments to an existing facility lease with the Navajo Nation which would extend the Four Corners leasehold interest to 2041. The amendments have been approved by the Navajo Nation Council and signed by the Nation’s President. The effectiveness of the amendments also requires the approval of the DOI, as does a related federal rights-of-way grant which the Four Corners participants will pursue. A federal environmental review will be conducted as part of the DOI review process. See Note 16 for additional information about Four Corners.
Luna Energy Facility
Luna is a combined-cycle power plant near Deming, New Mexico. Luna is owned 33.33% by PNM, 33.3% by Tucson and 33.3% by Freeport McMoran. The operation and maintenance of the facility has been contracted to North American Energy Services.
Construction Program
The Company anticipates making substantial capital expenditures for the construction and acquisition of utility plant and other property and equipment. A summary of the budgeted construction expenditures, including expenditures for jointly-owned projects, and nuclear fuel, is as follows:

The construction expenditure estimates are under continuing review and subject to ongoing adjustment, as well as to Board review and approval. The construction expenditures above include additional renewable resources anticipated to be required to meet the RPS, additional peaking resources needed to meet needs outlined in PNM's current IRP, and environmental upgrades at Four Corners of $71.9 million estimated to be expended through 2017. The construction expenditures above do not include any amounts for environmental upgrades at SJGS that ultimately may be required by EPA to address regional haze (Note 16) or expenditures that could be required to replace capacity should environmental control at SJGS involve shutdown of one or more SJGS units.
