Dayton Power & Light (DP&L) on Oct. 3 filed with the Ohio Power Siting Board (OPSB) a pre-application notification letter, providing notice of the company’s proposed West Milton-Eldean 138-kV Transmission Line Project.
The project would ensure that adequate transmission system voltages are maintained in the northwest area of the DP&L transmission system under various conditions, as required to comply with the mandatory NERC reliability standards, the company said.
The project entails building about 17 miles of new 138-kV transmission line from the existing West Milton substation to the existing Eldean substation, located northwest of Troy in Miami County, Ohio. DP&L also said that it estimates that the project would cost about $12m, and be in service by 2022.
It is anticipated that the new line would be installed on single wood poles, with steel poles at select locations, averaging 70 feet to 90 feet in height. The company added that the line would also include conductor, shield wire, and associated hardware.
The routes under consideration largely follow road right of way (ROW) – often where electric distribution lines already exist – and DP&L’s existing line ROW – south and west of West Milton. DP&L added that the proposed routes were also designed to align with property lines.
The company noted that it expects to file an application for a certificate of environmental compatibility and public need for the project with the OPSB in February 2019.
DP&L said that it plans to hold a public information meeting on Nov. 7 in Troy, Ohio.
Among other things, the company said that an OPSB administrative law judge last month issued a ruling granting a request for waivers of Ohio Administrative Code Section 4906-3-05, which requires that the alternate route should not have more than 20% in common with the preferred route.
As TransmissionHub reported, DP&L, in an Aug. 1 filing submitted with the Public Utilities Commission of Ohio (PUCO), requested that a docket involving its proposed West Milton-Eldean 138-kV Transmission Line Project be closed.
The docket, PUCO Case Number 14-0469-EL-BTX, was opened and a pre-application notification letter was filed with the OPSB in March 2014, the company said.
“Since that time, the project was delayed and OPSB staff recently informed DP&L that, in staff’s view, the project would have to be re-filed with a new case number,” the company said. “DP&L is willing to proceed forward on this basis and, thus, DP&L is not anticipating any further filings of docket 14-0469-EL-BTX and requests that this docket be closed.”
DP&L also said at the time that it will file a new application for the same project in the near future.
A company spokesperson on Aug. 10 told TransmissionHub that the OPSB has required the company to rewrite and submit to the OPSB an application to conform to new rules, which starts the process over.
"Our plan is to have another open house meeting and submit the application to" the OPSB by the end of the year, she said, adding that the expectation is to have approval in 2019, with construction starting in 2021, and the project being in service in 2022.
The project was delayed as the company investigated schedules and budgets to best fit system loading and PJM Interconnection requirements, the spokesperson said.
"By the time a favorable internal and PJM schedule were established the rules changed and sufficient time had passed," she said. "This resulted in the board requesting we refile based on new rules."
