Tenaska Gas-Fired Plant Comes Online in Pennsylvania

January 2, 2019

The Tenaska Westmoreland Generating Station began commercial operation on Dec. 21, the latest natural gas-fired facility to enter the PJM market.

The 940-MW Tenaska plant, located near Smithton in South Huntingdon Township in Westmoreland County in southwest Pennsylvania, was built in just more than two years, though its planning and permitting process took several years due to opposition from local residents.

The plant is part of a move toward more gas-fired power in PJM, the largest competitive wholesale U.S. power market. PJM serves customers in 13 states in the eastern U.S., and the District of Columbia.

Gas-fired power surpassed coal-fired generation as the fuel of choice in PJM in 2015, as the price of natural gas dropped below the cost of coal across the region. According to a recent report from the U.S. Energy Information Administration (EIA), “The monthly average cost of Central Appalachian coal in the PJM region averaged $ 2.76 per million British thermal unit (MMBtu) in 2013 and has only slightly increased since then, most recently averaging 3.30/MMBtu in 2017.”…

Unit 4 of the Tianwan Nuclear Power Plant in China entered commercial operation this past weekend after completing commissioning. It began supplying power to the country’s national grid on Dec. 22.

Tianwan NPP is the largest facility built with a Russian-Chinese framework of economic cooperation, with Units 1 through 4 based on the VVER-1000 reactor type. Units 1 and 2 entered commercial operation in 2007, and Rosatom handed over Unit 3 to Jiangsu Nuclear Power Corp. (JNPC) in March of this year.

Tianwan Unit 4 was brought to its minimum controllable power level on Sept. 30, marking the final stage of first criticality procedures, which began Aug. 25 when the first fuel assembly was installed in the reactor. A total of 163 fuel assemblies were ultimately loaded.

Russia’s Atomstroyexport was general contractor for the project, working with JNPC. Alexey Bannik, vice president for projects in China with Rosatom’s engineering division, said the start of commercial operation of Unit 4 “means that a two-year warranty period for the plant operation has commenced, and once expired the Unit will ultimately be handed over to the Chinese Party.”…

New York Gas Plant Comes Online Despite Opposition

The Valley Energy Center in Orange County, New York, entered commercial operation on October 1 despite complaints from local officials and area residents about noise from the plant, among other concerns.

Community members spoke out against the plant at public hearings last week, saying they have felt sick when the plant has undergone test runs over the past several months. Orange County officials and local politicians said they support a decision by the state Department of Environmental Conservation (DEC) not to renew the air permit for the plant, though the plant is allowed to operate while a court decides the permit issue.

The DEC has said the plant needs a federal Title V air permit. Competitive Power Ventures (CPV), the plant’s operator, has argued it has one year to obtain the permit after beginning full-time operation.

The Valley Energy Center is a 675-MW gas-fired plant in Wawayanda. It was originally scheduled to begin commercial operation in February, but its opening was delayed because the DEC had not finished permitting Millennium Pipeline Co.’s…

Florida Power & Light (FPL) began the new year by opening four new solar power plants, along with officially retiring one of its two remaining coal-fired plants in the state.

The utility on January 8 said the four solar plants began operating on January 1, 2018. They are the Horizon Solar Energy Center, in Alachua and Putnam counties; the Coral Farms Solar Energy Center in Putnam County; the Indian River Solar Energy Center in Indian River County; and the Wildflower Solar Energy Center in DeSoto County. Each has a generation capacity of 74.5 MW.

The utility plans to add four more 74.5-MW solar plants to its generation fleet by March 1, 2018, sited in Brevard, Indian River, Hendry, and St. Lucie counties. FPL has installed more than 3.5 million new solar panels in the state over the past two years. It expects to have more than 10 million solar panels in service by 2023.

“The truth is progress like this doesn’t happen by accident,” Eric Silagy, FPL’s president and CEO, said in a statement.…
