PNM Files Rate Case Stipulation with New Mexico Regulators

The agreement, or stipulation, was reached with several key parties, including staff of the N.M. Public Regulation Commission and the state Attorney General's Office. It requires approval from the Commission to be implemented. Among the elements called for by the stipulation are:

• A first-phase increase of $45 million, or 5.7 percent, beginning May 15;
• A second-phase increase of $40 million, or 5.1 percent, beginning Jan. 1, 2012;
• An "Additions Rider" capped at $20 million, to cover changes in plant-related rate base between June 30, 2010, and December 31, 2012. The rider would be effective Jan. 1, 2013, through Dec. 31, 2013;
• A separate renewable energy rider beginning July 1, 2012, for the recovery of costs associated with Commission-approved renewable energy procurement plans, including PNM's investment in its utility-scale solar power facilities totaling 22 megawatts.

According to the stipulation, PNM's next general rate adjustment cannot go into effect before Jan. 1, 2014, with the exception that PNM can file for recovery of costs to comply with any federal or state environmental law or requirement effective after June 30, 2010. The stipulation is a "black-box" settlement, meaning parties agreed to a specific revenue increase number, but did not agree on a specific cost-of-service or any adjustments in arriving at the rate increase. PNM's illustrative cost-of-service that will be filed in support of the rate increase will include an implied return on equity of 10.25 percent on a rate base of $1.8 billion and a capital structure consisting of 47.49 percent long-term debt, 0.52 percent preferred stock and 51.99 percent common equity.

"Since 2007, our utilities' efforts have focused on reducing operating costs. And, every year since, we have taken steps toward facilitating trust and a better understanding of the need for consumer rates to properly reflect those costs," said Pat Vincent-Collawn, PNM Resources president and CEO. "This agreement provides PNM with the certainty of a rate path that stretches to the end of 2013, while balancing the need to keep consumers' costs as low as possible. The settlement removes uncertainty for the utility and its customers, provides a roadmap for PNM to earn its allowed return within the three-year period and allows us to continue to focus on cost control."

Vincent-Collawn said the proposed rate-recovery structure would increase PNM after-tax earnings by approximately $20 million, or $0.22 per diluted share, in 2011, and by an incremental $31 million, or $0.34 per diluted share, in 2012. The stipulation also provides a recovery path for costs associated with the state Renewable Energy Act. Recovery of PNM's investment in its solar facilities is estimated to be $18.0 million in 2012, which is expected to add $0.02 per diluted share to current earnings.

In addition to Commission staff and the Attorney General's Office, other signatories to the stipulation include the Albuquerque Bernalillo County Water Utility Authority, the Buckman Direct Diversion Board, the City of Alamogordo and the New Mexico Industrial Energy Consumers.
