Cause of San Juan Generating Station cooling tower collapse remains unknown

While the cause of the collapse of a cooling tower at unit one of the San Juan Generating Station has not yet been identified, Public Service Company of New Mexico has provided the New Mexico Public Regulation Commission with some more information regarding the event. Following the collapse, the PRC issued a notice of inquiry into the incident, which occurred in late June, and opened a docket. PNM filed a response to questions raised in the notice of inquiry on Aug. 16 and the commission discussed the response during the weekly meeting on Wednesday. In its response, PNM stated that the cause of the collapse has not yet been identified.

San Juan Generating Station taken offline after cooling tower collapse

Unit one of the San Juan Generating Station was taken off line last week after a cooling tower collapsed, sources familiar with the incident told NM Political Report. The cooling tower is necessary to operate the unit and, unless it is repaired, the unit will not be able to produce power for Public Service Company of New Mexico and Tucson Electric Power. The two utilities share ownership of the unit and each receives 170 megawatts of power. No one was injured during the June 30 collapse, which came almost exactly one year before the state’s largest utility plans to end operations of the power plant. The plant was idle on the morning of July 6 and neither unit one nor unit four were producing power.

Critics say PNM, Avangrid merger could hurt ratepayers, environment

Government entities, utilities and watchdog groups say a merger between Public Service Company of New Mexico and Avangrid could harm both ratepayers and the environment unless protections are included. These entities filed testimony in a New Mexico Public Regulation Commission case evaluating the merger. This merger is subject to the PRC approval as well as approval from the Federal Energy Regulatory Commission. PNM’s parent company, PNM Resources, is seeking to merge with Avangrid, a U.S. subsidiary of renewable energy giant Iberdrola, which is based in Spain. The PRC hearings related to the merger are scheduled to start on May 3 and testimony has been filed expressing a variety of concerns.

PRC orders PNM to address past use of Palo Verde as it seeks to end its leases at the facility

State regulators asked the state’s largest utility to defend a past decision to continue leasing shares of a nuclear power plant as it now asks regulators to approve replacing that electricity with renewable sources. Public Service Company of New Mexico (PNM) has filed to replace the energy it gets from leased shares of the Palo Verde Nuclear Generating Station with renewable sources. The filing came earlier this month and the New Mexico Public Regulation Commission issued an order beginning the process, which was unanimously approved on April 21. The order requires PNM to file additional testimony regarding unresolved issues from a 2015 case. These unresolved issues are about a decision to acquire additional leases and extend its leases in the Palo Verde facility.

Connecticut-based utility company agrees to buy PNM Resources

The company that owns New Mexico’s largest utility PNM is being acquired by Avangrid, a Connecticut-based utility owner, in a merger deal totalling $8.3 billion. The two companies announced the deal early Wednesday. 

Avangrid operates natural gas and electric utilities and renewable energy generation assets across 24 states. The investor-owned company’s headquarters are located in Orange, Connecticut, but the majority shareholder is Spain-based Iberdrola, S.A., which is the third largest utility company in the world. 

Avangrid’s renewable energy-focused arm is considered one of the largest in the world. It’s the third largest wind energy operator in the U.S., with 7.4 gigawatts of installed wind and solar capacity. The company owns 1.9-gigawatt capacity wind projects in New Mexico and Texas and 200 megawatts of wind and solar capacity in Arizona.

Supreme Court declines to rule on constitutionality of ETA

The New Mexico Supreme Court denied a request to determine the constitutionality of the Energy Transition Act (ETA) on Tuesday. The decision was released without an opinion. In August, the advocacy nonprofit New Energy Economy (NEE) filed a writ of mandamus asking the Court to rule on whether portions of the ETA are unconstitutional. The writ alleges that wording in the ETA removes the Public Regulation Commission’s (PRC) regulatory oversight of Public Service of New Mexico (PNM) and proposed rate increases. New Energy Economy’s executive director, Mariel Nanasi, announced the court decision at a panel discussion in Santa Fe Tuesday evening. 

“We believe the ETA is unconstitutional, especially in regards to its eviscerating the regulatory authority [of the PRC],” Nanasi said.

Suit alleges ETA a ‘deregulation law’ for PNM

A group of organizations filed a lawsuit in the state Supreme Court this week that alleges the Energy Transition Act is a deregulation law for PNM, and are challenging provisions in the law as unconstitutional. The suit from New Energy Economy, a Santa Fe-based advocacy nonprofit, and six other groups claims the ETA removes some of the authority given to the Public Regulation Commission (PRC) to regulate the Public Service Company of New Mexico (PNM) and its proposed rate increases associated with its fossil fuel assets. PNM is an investor-owned utility that operates as a monopoly in parts of New Mexico. As a utility, the company has an obligation to serve its customers—the ratepayers—in the most efficient manner and at the lowest possible cost. But as a publicly-traded company, PNM also has an obligation to its shareholders to generate profit.

Enchant Energy disputes criticisms of carbon capture proposal for coal plant

Enchant Energy, the company that plans to turn the San Juan Generating Station near Farmington into the world’s largest carbon capture system, responded to criticisms made in a recent report, blasting the proposal. NM Political Report spoke with the Institute for Energy Economics and Financial Analysis (IEEFA) report author Karl Cates about his concerns for the proposal last month. RELATED: Energy think tank blasts carbon capture proposal for San Juan coal plant

Enchant Energy addressed a number of issues raised by the IEEFA report in a document posted to the company’s website in late July. The company reiterated its belief that the proposed carbon capture system offers a cost-effective, low-emission solution to keep the coal-fired San Juan Generating Station open. “Contrary to the IEEFA assertion, Enchant Energy is not making hard and fast ‘presumptions,’” the company said, pointing to a pre-feasibility study the company commissioned earlier this summer from global engineering firm Sargent & Lundry.

Energy bill’s passage portends end of coal era in NM

The Legislature has moved to Gov. Michelle Lujan Grisham’s desk a controversial bill designed to dramatically increase the amount of renewable energy used to produce electricity in New Mexico while also helping the Public Service Company of New Mexico recoup its investments in the coal-burning San Juan Generating Station near Farmington. Following a three-hour debate Tuesday, the House passed Senate Bill 489 by a margin of 43-22. It was a mostly party-line vote, with almost all Democrats in favor of the bill and almost all Republicans voting against it. The measure goes now to Lujan Grisham, who has enthusiastically supported it. How PNM’s electrical rates will be affected was a major point of contention during debates over the bill in the Legislature.

After filibuster, Senate OKs power plant shutdown bill

A bill aimed at shutting down the coal-burning San Juan Generating Station and strengthening New Mexico renewable energy standards survived a rambling 3 1/2-hour filibuster and other parliamentary maneuvering by opponents in the state Senate on Wednesday night. But one victim of the games on the Senate floor was the annual House vs. Senate basketball contest at the Santa Fe Indian School gym, an annual benefit for the University of New Mexico’s Comprehensive Cancer Center. The Senate team had to concede and return to the Capitol, some members arriving in the Senate chamber still wearing basketball gear, because the debate on Senate Bill 489 — dubbed the Energy Transition Act — went on well into the night. State Sen. Cliff Pirtle returned to the Senate floor wearing his jersey for the House-Senate basketball game and the rules-mandated tie.
