Operator Reverses Course, Will Keep Running Montana Coal Plant

August 13, 2017

The operator of one of the largest coal-fired power plants in the Western U.S. will continue to run the facility, changing course about a year after a company executive said the plant was not economically viable.

A spokesman for Talen Energy confirmed to POWER on August 9 that the company will continue to operate the 2,094-MW Colstrip Generating Station in Montana. The company last year told the ownership group it would need to find a new operator by mid-2018.

Todd Martin, a spokesman for Talen, told POWER in an email: “I can confirm that the ownership group has determined that Talen Montana will continue to operate the Colstrip Station.” He said the company would have “no additional public information to share at this time.”

The Billings (Mont.) Gazette first reported August 9 that Colstrip would remain open, based on its interviews in the past week with representatives of the six utilities that co-own the plant.

Montana legislators earlier this year approved a deal that would allow Pennsylvania-based Talen to borrow up to $ 10 million a year to keep the plant operating until 2022.…

Exelon could begin construction as soon as next week on an expansion of its 135-MW West Medway oil-fired peaking plant in West Medway, Massachusetts. The company’s plan to add two units and 200 MW of generation to the existing three-unit facility was deliberated for 29 months by state and local officials before a state board approved the expansion August 4.

The expansion includes the installation of two GE LMS100 dual-fuel turbines, operating primarily on natural gas but also using ultra-low-sulfur diesel as backup for a maximum 30 days a year. The company’s website says the new units could start up and be online in about 10 minutes. Exelon in its reports on the project says the gas-fired generation will reduce CO₂ emissions by 40% when it displaces generation from the three older units.

The construction, which will include two 160-foot emission stacks, along with a 50-foot sound barrier to minimize noise, reportedly is expected to take 14 months to complete.…

The Federal Energy Regulatory Commission (FERC) again has a working quorum after the U.S. Senate confirmed Neil Chatterjee and Robert Powelson as new members August 3. FERC had been without a quorum since February 2017 when Commissioner Norman Bay resigned, and with only one member after Collette Honorable left the agency at the end of June.

Sen. Lisa Murkowski (R-Alaska), chairman of the Senate Committee on Energy and Natural Resources, released a statement that said the Senate approved Chatterjee and Powelson by unanimous consent. Murkowski said she has scheduled a hearing for September 7 before the Energy and Natural Resources Committee to consider two more nominees, Richard Glick and Kevin McIntyre, for the agency. FERC has long been a five-member agency, and by law requires three commissioners to make up a quorum and have the ability to conduct its full range of business.

Enviros Call for Court Decision in Clean Power Plan Case

Given that the Environmental Protection Agency (EPA) isn’t going to be taking any substantial action to rewrite the Clean Power Plan anytime soon, the U.S. Court of Appeals for the District of Columbia Circuit should not postpone a decision in the court case against the rule, an August 4 document filed by a group of environmental intervenors in the case argues.

The case against the Clean Power Plan was argued in court on September 27, 2016, before a panel of 10 judges. In the more than ten months since the hearing, the court has not issued a decision in the case.

The situation got more complicated after the election of President Donald Trump, an opponent of the rule, and the nomination of former Oklahoma Attorney General Scott Pruitt, who had sued the former administration’s EPA over the rule, as the new administrator of the EPA.

Pruitt’s EPA announced right away that it would be reviewing the rule, as he believes it represents an overreach of the EPA’s authority under the Clean Air Act.…

Judge Rules TVA Must Move Gallatin Coal Ash

A federal judge on August 4 said the Tennessee Valley Authority (TVA) must dig up coal ash at one of its power plants and move it to a lined waste site. The order came in a suit filed by the Tennessee Scenic Rivers Association (TSRA) and the Tennessee Clean Water Network (TCWN), who said coal ash stored at the TVA’s Gallatin Fossil Plant has been polluting the nearby Cumberland River for decades in violation of the Clean Water Act.

U.S. District Judge Waverly Crenshaw in Nashville, Tenn., said that although there is little evidence thus far that seeping coal ash has polluted the river, uncertainty about future pollution and its possible danger will continue to create conflicts, and moving the ash is the best way to resolve an “untenable situation that has gone for far too long.” The Southern Environmental Law Center in 2014 announced its intention to represent the two environmental groups in the suit.

The case involves a coal ash pit at Gallatin that was closed in 1970, but where the coal ash ponds remain in use.…

DTE Plans New 1,100-MW Gas Plant Near Detroit

DTE Energy has filed plans with the Michigan Public Service Commission (MPSC) to build a 1,100-MW natural gas-fired power plant on about 100 acres east of the existing Belle River Power Plant, northeast of Detroit near the Canadian border. The August 1 filing confirms the proposal that DTE discussed with local officials last fall for a new plant at the site. DTE said it expects the plant will begin operating in 2022.

The proposed $ 1 billion plant, located in East China Township in St. Clair County, is part of the utility’s plan to replace coal-fired electricity production in the region as it seeks to reduce carbon emissions by 30% by the early 2020s, and by more than 80% by 2050. DTE has said it will retire three coal-fired plants, located in Trenton, River Rouge, and St. Clair in the Detroit area, between 2020 and 2023. The certificate of necessity filed with the MPSC calls for construction of the new plant to begin in 2019, pending state approval; the state has 270 days to respond to the filing.…
