ALBUQUERQUE, N.M., May 30, 2018 /PRNewswire/ — PNM Resources’ (NYSE: PNM) transmission and distribution utility in Texas, TNMP, today filed its anticipated general rate review. The filing is TNMP’s first general rate review since current rates were approved in 2011 and provides for a realignment of rate recovery between transmission and distribution investments. The net increase to rate base is $90 million, which is incremental to previous Transmission Cost of Service (TCOS) filings and Advanced Metering System (AMS) investments.

The filing reflects an annual increase to base rates of $25.9 million, based on a requested return on equity of 10.5% and capital structure comprised of 50% debt and 50% equity. Current rates are based on an allowed return on equity of 10.125% and a 45% equity ratio. TNMP has also requested $7.7 million of new rate rider recovery primarily for Hurricane Harvey restoration and additional vegetation management costs. If approved by the Public Utility Commission of Texas, new rates are expected to become effective in early 2019 and increase the average residential customer bill by 11 percent.

«Our service territory in Texas has experienced significant growth over the last several years and we have increased our capital investment in the system to accommodate this growth while maintaining reliability for both new and existing customers,» said Pat Vincent-Collawn, PNM Resources’ chairman, president and CEO. «Our use of semi-annual TCOS filings has provided recovery for our transmission investments, but this filing provides the opportunity to reset base rates between our transmission and distribution businesses. We have worked to minimize cost increases in Texas and keep our rates affordable, and the income tax savings from federal tax reform reduces the impact of this filing to our customers.»

The base rate increase includes the integration of AMS recovery into base rates, including collection of the remaining unrecovered investment. Updates to depreciation rates and the pass-through of federal tax reform savings also impact the filed increase but do not result in changes to net earnings. Schedule 1 below summarizes the key components of the rate filing.
