Gas-fired power projects make news in August 2016

A number of gas-fired power projects have advanced or at least been subject to major developments in August of this year, according to reporting done by Generation Hub.

Some of the major developments during the month were:

  • Oregon Clean Energy LLC on Aug. 22 filed at the Federal Energy Regulatory Commission (FERC) its market-based rate tariff, saying it anticipates the commencement of commercial wholesale power activities by early 2017, and that the facility will be energized for testing purposes by late December 2016. Applicant owns and will operate an approximately 960-MW natural gas-fired combined cycle generator located in Oregon, Lucas County, Ohio. The facility will be interconnected with American Transmission Systems Inc. (ATSI), whose transmission system is operated by the PJM Interconnection.
  • NTE Connecticut LLC applied Aug. 17 at the Connecticut Siting Council for a Certificate of Environmental Compatibility and Public Need for the construction, maintenance, and operation of a 550-MW, dual-fuel combined cycle facility and associated electrical interconnection switchyard located at Killingly, Conn. The Killingly Energy Center (KEC) is designed to competitively serve the existing and future demand for electricity generation in Connecticut and throughout the New England regional transmission system. The primary source of fuel for KEC will be natural gas. During times of natural gas curtailment or service interruption, KEC will operate on ultra-low sulfur distillate (ULSD) as a backup fuel. NTE proposes to install one Siemens SGT6-8000H combustion turbine generator (CTG) that will produce approximately 300 MW (nominal).
  • The Texas Commission on Environmental Quality posted to its website on Aug. 19 a notice that said it is close to a decision on a Southern Power application for a Greenhouse Gas (GHG) Prevention of Significant Deterioration (PSD) permit, which would authorize construction of the Jackson County Generating Facility. Southern Power is a non-utility unit of Southern Co. (NYSE: SO). The power plant property is south of Lundquist Road at the intersection of Texas County Road 710 and Lundquist Road, Ganado, Jackson County, Texas. The plant will consist of four natural gas-fired simple-cycle CT generator units capable of producing a nominal 920 MW.
  • Michigan Gov. Rick Snyder said Aug. 15 that an agreement providing for a potential long-term, clean power solution for the state’s Upper Peninsula has been reached between iron ore producer Cliffs Natural Resources and WEC Energy Group. The proposed solution is expected to be cost-competitive for Cliffs and save money for residential customers of the Upper Peninsula. This new agreement, if approved, would result in 170 MW of new natural gas-fired generation across two sites in the Upper Peninsula. In addition, these plans will allow for the retirement of WEC Energy Group’s coal-fired Presque Isle Power Plant in Marquette by 2020.
  • Black & Veatch said Aug. 17 that it has been selected to provide engineering, procurement and construction (EPC) services for a 925-MW, natural gas-fired combined cycle plant in Pennsylvania. The Tenaska Westmoreland Generating Station is located near Pittsburgh and will supply electricity to customers in Pennsylvania and 12 other Northeastern states that operate in the PJM market. The plant features Mitsubishi Hitachi Power Systems J-series natural gas turbines. The project includes a 500-Kv switchyard and switching station as well as 1.5 miles of power transmission lines to connect it to the PJM grid. Project construction began in 2016 with commercial operation scheduled in 2018.
  • The AES Southland Development LLC unit of AES Corp. (NYSE: AES) and the City of Redondo Beach filed anAug. 12 notice with the California Energy Commission that they want a continued suspension of the approval proceeding for the Redondo Beach Energy Project until Feb. 1, 2017. In November 2012, AES Southland submitted this Application for Certification (AFC) seeking permission to construct and operate the Redondo Beach Energy Project (RBEP), located at 1100 North Harbor Drive in the City of Redondo Beach, Los Angeles County. It would be within the footprint of the existing Redondo Beach Generating Station. The RBEP is a proposed natural-gas fired, combined-cycle, air-cooled facility with a net generating capacity of 496 MW, which will replace the Redondo Beach Generating Station. RBEP will consist of one three-on-one, combined-cycle gas turbine power block with three natural-gas-fired combustion turbine generators (CTG), three supplemental-fired heat recovery steam generators (HRSG), one steam turbine generator (STG), an air-cooled condenser, and related ancillary equipment.
  • The North Carolina Utilities Commission (NCUC) on Aug. 16 issued its schedule to review a July 29 application from NTE Carolinas II LLC for a certificate of public convenience and necessity (CPCN) to construct a natural-gas fueled merchant generating facility in Rockingham County, North Carolina. The company intends to construct a 500-MW combined cycle combustion turbine facility to be fueled by natural gas. Construction is anticipated to begin in the first quarter of 2018. The location of the proposed facility is an approximately 90-acre tract located at 4781 NC Highway 65, and bounded by NC Highway 65 to the east and New Lebanon Church Road to the west, in Reidsville, Rockingham County, North Carolina.
  • Funds managed by BlackRock’s Alternative Solutions Group, in partnership with BlackRock Real Assets, have entered an agreement to invest approximately 10% in the 1,100 MW combined cycle gas turbine (CCGT) Cricket Valley facility in New York. BlackRock noted in an Aug. 16 statement that the project will utilize proven General Electric 7FA.05 combustion turbine generators. Construction of the plant is expected to begin in the fourth quarter of 2016 and to be completed in the fourth quarter of 2019.
  • FERC on Aug. 15 accepted a June 27 filing by ISO New England and interconnecting transmission owner NSTAR Electric of an executed non-conforming Standard Large Generator Interconnection Agreement with Exelon West Medway II LLC for a planned expansion of a gas-fired power plant in Massachusetts. The deal governs the interconnection of this new capacity at NSTAR’s 115-kV Medway Station. This new facility will be comprised of two new simple cycle combustion turbine generators (CTG), designated CTG1 and CTG2, each rated at 103.467 MW. The commercial operation target date for this new generating facility, under the agreement, is April 17, 2018. The project company is a subsidiary of Exelon (NYSE: EXC).
  • The California Public Utilities Commission said in an Aug. 11 notice that it has decided that some changes for the on-hold Oakley Generating Station project can be handled on the staff level, without an approval from commissioners. On May 9, staff docketed an amendment petition submitted by Contra Costa Generating Station LLC requesting modifications to the Oakley Generating Station (OGS). The petition requests changes to the location of the generator tie-line conductor support tower 2/21 and a corresponding modification to the generator tie-line alignment between tower 2/21 and tower 2/22. The OGS is a 624-MW combined cycle facility located in the city of Oakley in Contra Costa County, California. The project was certified by the Energy Commission in May 2011, and was authorized to commence construction in July 2011. The project’s construction phase is not complete as it is currently on hold, the commission noted.
  • The Virginia Department of Environmental Quality is taking comment until Sept. 13 on a draft Prevention of Significant Deterioration Permit that would allow Doswell Limited Partnership to add two combustion turbines at the existing Doswell Energy Center in Ashland, Va. Doswell Limited Partnership wants to add two General Electric 7FA.03 simple cycle combustion turbines, each rated at 170 MW (called CT-2 and CT-3). The Doswell Energy Center (DEC) is currently composed of four Kraftwerk Union/Siemens (Model: V84.2) combined cycle turbine units each equipped with a duct burner and supporting equipment, and one simple cycle turbine unit.
  • The Ohio Environmental Protection Agency has been accepting public comments in August on a draft permit for the South Field Energy LLC combined-cycle gas turbine facility to be located in Wellsville, Columbiana County. The permit would allow the installation of a 1,150-MW station that will utilize two combustion turbine generators, two supplementary heat recovery steam generators, two steam turbine generators and two cooling towers. Each gas turbine will have its own 180-foot stack. Additional equipment includes an auxiliary boiler, emergency diesel generator, emergency diesel fire pump and various storage tanks. Natural gas will be the primary fuel burned for the two combustion turbine generators, with ultra-low sulfur diesel as a secondary fuel.
  • Moundsville Power LLC, which is developing a gas-fired power project in northern West Virginia, on Aug. 5 asked the state Public Service Commission to waive any need to get a further approval for an uprate of the project. The power project is located in Marshall County. The commission granted a siting certificate for the project in February 2015. The proposed increase of approximately 124 MW of nominal capacity is made possible due to the anticipated reduction of constraints at the point of interconnection at the George Washington Substation, which will allow realization of the full potential of the turbines for the facility. The project was approved at 549 MW in size. The facility will utilize state-of-the-art natural gas-fueled generating equipment manufactured by General Electric, including two combustion turbines, two combustion turbine generators, two heat recovery steam generators, a single steam turbine and a steam turbine generator.
  • The updated capital plan for 2016-2018 for Entergy Corp. (NYSE: ETR) reflects capital plan refinements and includes specific investments in gas-fired capacity, said Entergy in its Aug. 4 quarterly Form 10-Q report. The financial report said these investments include: the purchase of the Union Power Station in Arkansas in March 2016; construction of the St. Charles Power Station and the New Orleans Power Station; the self-build option at Entergy Louisiana’s Nelson site selected in a request for proposal (RFP); and the self-build option at Entergy Texas’s Lewis Creek site selected in another RFP. In August 2015, Entergy Louisiana filed with the Louisiana PSC an application for certification of the St. Charles Power Station, a nominal 980-MW combined-cycle unit, on land adjacent to the existing Little Gypsy plant in St. Charles Parish, Louisiana. In June 2016, Entergy New Orleans filed an application with the City Council seeking a public interest determination and authorization to construct the New Orleans Power Station, a 226-MW advanced combustion turbine in New Orleans at the site of the existing Michoud generating facility, which was deactivated effective May 31, 2016. The Form 10-Q does not describe the Nelson and Lewis Creek projects outside of mentioning them in general. Descriptions of these projects from the RFPs are: Nelson would be a CCGT facility at Entergy’s Nelson site in Westlake, Louisiana, that would be sized at no less than 650 MW (summer conditions, at full load, including duct-firing) and no more than 1,000 MW; and Lewis Creek is a CCGT facility that would be built at the Lewis Creek site in Willis, Texas, and will be sized at no less than 800 MW (summer conditions, at full load, including duct firing) and no more than 1,000 MW.
