American Transmission Systems, Incorporated (ATSI), a FirstEnergy (NYSE:FE) company, earlier this month filed with the Ohio Power Siting Board (OPSB) a letter as the pre-application notification letter for three related projects, collectively referred to as the Springfield Area 138 kV Reinforcement Project, which consists of three separate components for which ATSI will seek OPSB approval.
The first component, ATSI added, is the proposed East Springfield-Tangy 138 kV Loop to Broadview Substation Project (Case No. 16-1982-EL-BTX); the second component is the Clark-Urbana 138 kV Loop to Broadview Substation Project (Case No. 16-1983-EL-BTX); and the final component is the proposed expansion of the Broadview substation (Case No. 16-1981-EL-BLN).
All of the component projects would be located in Moorefield Township, Clark County, the company said.
A company spokesperson on Oct. 26 told TransmissionHub that the Springfield Area 138 kV Reinforcement Project is estimated to cost $40m.
A public informational meeting required for the proposed East Springfield-Tangy 138 kV Loop to Broadview Substation Project and the Clark-Urbana 138 kV Loop to Broadview Substation Project is scheduled to take place on Oct. 26in Springfield, Ohio.
ATSI also said that it will file a full application for a certificate of environmental compatibility and public need for each proposed transmission line loop. The company noted that it plans to make the necessary submittals to the OPSB for the project in mid-January 2017, and if OPSB approval is granted, the company expects to begin construction in December 2017, and complete construction by September 2018.
The project involves the expansion and conversion of the existing Broadview substation and the interconnection of that substation to both the East Springfield-Tangy and Clark-Urbana 138-kV transmission lines. ATSI added that it anticipates filing a related letter of notification application for the expansion of the existing 69-kV Broadview substation into a 138-kV to 69-kV transformation substation in Case No. 16-1981-EL-BLN.
The company noted that the expanded portion of the substation would be about 55,000 square feet in size, with a new total area of about 110,000 square feet. ATSI said that it will include information on the proposed substation expansion at the public informational meeting.
Both the East Springfield-Tangy 138 kV Loop to Broadview Substation Project, which is likely to be about 5.5 miles long, and the Clark-Urbana 138 kV Loop to Broadview Substation Project, which is likely to be about two miles long, will be filed with the OPSB as full applications under the board’s rules.
The company also said that the installation of the new transmission line loops and the corresponding substation expansion are needed to meet electric load requirements for the project area, and to provide adequate supply to meet planning requirements for the transmission system.
The installation of the new line loops and the corresponding substation expansion, ATSI said, will assist in ensuring the long-term reliability of transmission service and operation in the project area.
