Entergy, Dominion, others advanced gas-fired power projects in May 2016

A number of gas-fired power projects moved forward in May, including plants that are both planned, in construction or completing construction.

Here is a rundown of project developments in May, as reported in Generation Hub:

  • The Pennsylvania Department of Environmental Protection said in a May 21 notice in the Pennsylvania Bulletin that it intends to issue an air plan approval to CPV Fairview LLC covering construction and temporary operation of a 1,020 MW (nominal) combined-cycle station known as the CPV Fairview Energy Center. CPV Fairview is a unit of Competitive Power Ventures. The project site is located in Jackson Township, Cambria County. The facility will include two General Electric (NYSE: GE) 7HA.02 combustion turbines in a 2-on-1 combined-cycle arrangement equipped with heat recovery steam generators (HRSG) with supplemental 425 MMBtus/hr fired duct burners controlled by selective catalytic reduction and oxidation catalysts. The combustion turbine fuels will be natural gas and an ethane blend (25% ethane and 75% natural gas, by volume), with ultra-low sulfur diesel (ULSD) fuel as back-up. The duct burners will utilize natural gas and the ethane blend only.
  • The Kahe combined cycle (CC) project will be a 3×1 CC unit consisting of three General Electric 6F.03 combustion turbines (CTs) and three heat recovery steam generators (HRSGs), which will use the waste heat from the CTs to produce steam to be utilized in a new steam turbine generator. The Kahe CC’s base capacity will be 358 MW, and for additional power production, the facility will be capable of utilizing wet compression technology during peak demand periods to add about 25 MW of capacity to the unit, totaling 383 MW, said Hawaiian Electric in a May 18 application for approval of this project filed with the Hawaii Public Utilities Commission. Together with planned merger partner NextEra Energy (NYSE: NEE), Hawaiian Electric decided on this project, which involves a partiall repowering of the existing Kahe power plant.
  • ESC Harrison County Power LLC has proposed a combined-cycle natural gas-fired facility located about 1.5 miles southeast of the Glen Falls substation in Harrison County, West Virginia, said a May 2016 study on the project from PJM Interconnection. The installed facilities will have a total capability of 550 MW with 550 MW of this output being recognized by PJM as capacity. The proposed in-service date for this project is June 1, 2020. This study does not imply a Monongahela Power commitment to this in-service date. A diagram in the study shows the project will be made up of a 437-MW combustion turbine and a 244-MW steam turbine. The West Virginia Secretary of State corporate database shows the only member of ESC Harrison County Power is Energy Solutions Consortium Holdings LLC, 360 Delaware Ave., Ste 406, Buffalo, NY 14202.
  • Duke Energy Florida said May 18 that the land is cleared, heavy equipment is arriving, and workers are being mobilized to build a 1,640-MW combined-cycle natural gas plant in Citrus County next to its existing Crystal River power plant. Duke Energy’s engineering, procurement and construction contractor, Fluor, is expected to start hiring 600 to 700 temporary construction workers gradually in spring 2016 with peak employment expected in 2017. Plant completion is expected in 2018.
  • Cricket Valley Energy Center LLC sent a May 16 letter to the New York State Public Service Commission accepting the commission’s April 20 approval of a power line for its 1,000-MW combined-cycle project. In 2013, the commission granted a Certificate of Public Convenience and Necessity to Cricket Valley Energy Center LLC to build the Cricket Valley Energy Center, a combined-cycle, natural-gas-fired, 1,000-MW facility in the Town of Dover in western Dutchess County. As a condition of that certificate, Cricket Valley was obligated to design, engineer and construct supporting transmission facilities in accordance with the New York Independent System Operator (NYISO) Class Year 2011 Facilities Study (or such later study as might become applicable).
  • The U.S. Department of Energy’s Office of Electricity Delivery and Energy Reliability said in a May 19 Federal Register notice that on April 12, Calpine New Jersey Generation LLC applied to cover a new combined cycle power plant under a coal capability self-certification. This self-certification is under the Power Plant and Industrial Fuel Use Act of 1978, which is a relic of the 1970s oil crisis days. This doesn’t mean there is any real-world plan to burn coal at this facility. The brief DOE notice said this project would be a nominal 446 MW in size using a General Electric turbine, or 456 MW (nominal) in size using a Siemens turbine. The project location is 373 North Broadway, Pennsville, New Jersey, DOE noted. The planned in-service date is on or after June 1, 2019. That is the address for Calpine’s Deepwater power plant.
  • The Federal Energy Regulatory Commission on May 13 released an environmental assessment on an application by Transcontinental Gas Pipe Line Co. LLC (Transco) for approval to construct, maintain, and operate the Virginia Southside Expansion Project II, located partially in Virginia. The project includes the construction and operation of 4.19 miles of 24-inch-diameter lateral pipeline connecting the existing Brunswick Lateral to the planned Virginia Electric and Power Co. (VEPCO) Greensville Power Station. The purpose of this project is to provide up to 250,000 dekatherms per day (250 million cubic feet per day) to VEPCO’s Greensville Power Station. Transco anticipates beginning construction in October 2016 (pending approvals) and placing the facilities into service by December 2017. Transco executed an agreement in May 2014 with Virginia Power Services (like VEPCO, a subsidiary of Dominion Resources (NYSE: D)) to provide natural gas transportation to this 1,580-MW, combined-cycle station.
  • Lackawanna Energy Center LLC is nearing a new air permit from the Pennsylvania Department of Environmental Protection covering changes to its 1,500-MW project, gas-fired project. The DEP said in a notice in the May 14 Pennsylvania Bulletin that it intends to issue the proposed Air Quality Plan Approval to construct, own, and operate a natural gas-fired combined-cycle plant to produce a nominal 1,500 MW of electricity in Jessup Borough, Lackawanna County, and is soliciting comments on that plan approval. Said the notice about this previously-permitted project: “This Plan Approval is for a configuration change to the plant layout but does not add any new emission sources or increase emission levels which have already been reviewed under Plan Approval 35-00069A. The modification proposes utilizing (3) smaller steam turbines and three (3) smaller air cooled condensers in place of the original planned single steam turbine and single air cooled condenser. Invenergy LLC announced April 25 that it recently held a groundbreaking ceremony for this project. It is expected to be operational in 2018.
  • Entergy Louisiana (ELL) intends to pursue its own self-build, gas-fired power project as a result of a just-concluded request for proposals (RFP) process that took into consideration third-party bids. Said a brief April 29 notice on the Entergy Corp. (NYSE: ETR) website: “Please be advised that Entergy Services, Inc. (ESI), acting under the oversight of the Independent Monitor, has concluded its evaluation of the proposals submitted in response to the 2015 ELL/EGSL RFP. After considering ESI’s evaluation of all RFP proposals, Entergy Louisiana, LLC has elected to proceed with the self-build alternative, which is generally described in the RFP, and a proposal for a power purchase agreement (PPA). Both the self-build alternative and, assuming negotiation of the definitive terms, the PPA will be conditioned on receipt of required internal and regulatory approvals.” EGSL is Entergy Gulf States Louisiana. No details are given on the possible PPA and whether the size of it would impact the size of the self-build plant. The September 2015 RFP says the Self-Build Option is a combined-cycle gas turbine (CCGT) facility that would be built at EGSL’s Nelson site in Westlake, Louisiana. The Self-Build Option will not have dual-fuel capability and will be sized at no less than 650 MW (summer conditions, at full load, including duct-firing) and no more than 1,000 MW (summer conditions, at full load, including duct firing).
  • The Entergy Texas Inc. (ETI) subsidiary of Entergy Corp. is aiming to build its own gas-fired power plant at the Lewis Creek site in Texas following rejection of outside bids from a request for proposals (RFP) issued last year. Said a brief April 28 notice on the Entergy website: “Please be advised that Entergy Services, Inc., acting under the oversight of the Independent Monitor, has concluded its economic evaluation of the proposals submitted in response to the 2015 ETI RFP. Upon consideration and evaluation of all RFP proposals, Entergy Texas, Inc. has elected to proceed with the self-build alternative, which is generally described in the RFP. The self-build alternative will be conditioned on receipt of required internal and regulatory approvals.” In that June 2015 RFP, Entergy Services said the Self-Build Option is a combined-cycle gas turbine (CCGT) facility that would be built at ETI’s Lewis Creek site in Willis, Texas. The Self-Build Option will attempt to optimize the maximum capacity of the proposed self-build resource by including in the base plant design heat recovery steam generator (HRSG) duct-firing and options for either chilling or evaporative cooling to the combustion turbine inlet. The Self-Build Option will not have dual-fuel capability 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 (summer conditions, at full load, including duct-firing).
  • Basin Electric Power Cooperative said May 10 that the first of the Wartsila engines at its new Pioneer Generation Station, which is located northwest of Williston, N.D., fired up on April 27. Phase III construction at Pioneer Generation Station is adding 110 MW into the grid, provided by 12 natural gas-based reciprocating engines that each have a generating capacity of 9.3 MW. First fire of the first reciprocating engine was achieved on April 27. As of May 9, six of the 12 engines had been fired, with the remaining engines firing up in the next several weeks. Pioneer was built to serve the increasing demand for electricity by member cooperatives in northwest North Dakota. Unit 1 started commercial operation in 2013, while Unit 2 and Unit 3 started commercial operation in 2014. Each of the three units has 45 MW of generation capacity.
  • The Public Service Commission of Wisconsin on May 6 approved a May 2015 application from Wisconsin Power and Light (WP&L) for a Certificate of Public Convenience and Necessity (CPCN) to construct a new natural gas-fired, combined-cycle (NGCC) facility with a nominal nameplate capacity rating of 650 MW. The project, known as the Riverside Energy Center Expansion project, includes construction of the NGCC facility and a 2-MW solar energy facility, and would be located near the site of the existing Riverside Energy Center in the town of Beloit in Rock County, Wisconsin. The estimated cost of the proposed project is approximately $700 million.
  • One new unit at the gas-fired Montana power plant in Texas went commercial May 3, and another is due for commercial operation in September, but owner El Paso Electric reported in a May 4 earnings statement that these new units, for now, are money losers, due to “regulatory lag” in getting costs passed through to ratepayers. On May 3, El Paso Electric placed into commercial operation the third generating unit at the MPS and the related common facilities and transmission systems at a cost of approximately $82.4 million. The 88-MW simple cycle aero-derivative combustion turbine is fueled by natural gas and has quick start capabilities which allows the unit to go from off-line to full output in less than 10 minutes, thus increasing overall power grid stability, and allowing to work in concert with the company’s renewable energy sources. MPS Unit 4, identical to the other three MPS units, is expected to reach commercial operation in September 2016.
  • Dominion Resources recently completed one major combined-cycle natural gas power plant in Virginia and is close to securing an air permit for another, Dominion Chairman, President and CEO Thomas Farrell II said May 4. Farrell made his comments during a regular quarterly earnings call. “We continue to execute with strong operational and safety performance while also investing in an array of clean energy infrastructure. Brunswick County, the 1,358-MW natural gas combined-cycle facility, was placed in commercial operation last week ahead of schedule. Our request for a Certificate of Public Convenience and Necessity (CPCN) and rate rider for the proposed 1,588-MW Greensville County project was recently approved by the Virginia State Corporation Commission,” Farrell said.
  • A Hearing Examiner at the Virginia State Corporation Commission issued a May 3 report recommending approval of a December 2015 application from Doswell Limited Partnership to construct a 340-MW facility in Hanover County, Virginia. Doswell proposes to build the project entirely on the site of the existing 155-acre Doswell Energy Center in Hanover County.
  • Lone Star Transmission LLC on May 2 filed at the Public Utility Commission of Texas a Standard Generation Interconnection Agreement (SGIA) with Shawnee Energy Center LLC for a new power plant to be made up of four Siemens combustion turbines. The Point of Interconnection for the project is located in Hill County, Texas, at the Sam Switch 345-kV station. The project will have four units with capacities of 232 MW each resulting in gross capacity of 928 MW. Each unit will be a Siemens STG-6 PAC 5000F model. The in-service date for the transmission infrastructure to support this project is the later of June 1, 2018, or thirteen months after the notice to proceed date. The scheduled generation commercial operation date is the later of Oct. 1, 2018, or two months after the transmission in-service date. The power project developer contact information in the agreement is for Lincoln Clean Energy.
