South Field Energy LLC (SFE), which is developing a 1,105-MW power plant, applied Jan. 15 at the Ohio Power Siting Board for approval of the power line that will interconnect that project to the grid.
South Field Energy, a wholly owned subsidiary of Advanced Power AG, is proposing to construct a 345-kV transmission line and switchyard in Columbiana County, Ohio. These facilities are associated with the South Field Energy project, a proposed combined cycle generating facility to be located on Hibbetts Mill Road in Columbiana County. The power plant is addressed in a separate application to the board submitted on Dec. 8, 2015.
Electricity generated by the plant will be delivered to the electrical grid at the existing FirstEnergy Highland-Sammis 345-kV transmission line located approximately 3.2 miles to the west of the plant site. This Jan. 15 application seeks a Certificate of Environmental Compatibility and Public Need for the interconnection facilities.
The schedule for construction of the interconnection facilities is based on commencement of commercial operation of the power plant by 2020, in order to meet anticipated demand within the PJM Interconnection marketplace. To meet this schedule, SFE is requesting issuance of the certificate by late spring 2016 to support commercial and financing activities in the third and fourth quarters of 2016 and commencement of construction in the first quarter of 2017.
SFE is within the corporate organizational structure of Advanced Power, an international developer of independent power generation projects. Advanced Power develops and invests in power generation and related infrastructure projects in North America and Europe. Advanced Power is currently developing three projects, totaling 2,500 MW, in the eastern United States. In addition, since 2006, Advanced Power has developed more than 1,500 MW of generation in the United States and Europe, including Carroll County Energy, a 750-MW generation facility planned in Carroll County, Ohio.
The South Field Energy facility is designed in a 2×2 configuration. The facility will primarily fire natural gas, with the capability to fire ultra-low sulfur distillate (ULSD) as back-up. It will utilize two integrated General Electric 7HA.02 combustion turbine generators (CTGs), each with a dedicated supplementary-fired heat recovery steam generator (HRSG); two steam turbine generators (STGs); and two mechanical draft wet cooling towers. The facility will have a nominal net output of 1,105 MW (full duct burner operation with inlet air cooling at 59 degrees Fahrenheit ambient temperature).
The existing Dominion Transmission Pipeline natural gas pipeline into which the facility will interconnect is located approximately 2 miles to the west of the facility site.
