In December 2018, PNM submitted an NMPRC required filing indicating that, consistent with the conclusions reached in PNM’s 2017 IRP, PNM’s customers would benefit from the retirement of PNM’s share of SJGS in mid-2022. As of December 31, 2018, PNM impaired $121.8 million of plant in service and $86.8 million of accumulated depreciation on its 132 MW and 65 MW interests in SJGS Unit 4. These amounts are reflected in the table above and as $35.0 million of pre-tax regulatory disallowances and restructuring costs in the Consolidated Statements of Earnings. See Note 16 for additional discussion of the NMPRC’s December 16, 2015 order regarding SJGS’s compliance with the regional haze rules under the CAA and PNM’s December 2018 Compliance Filing.
