EDP unit seeks Ohio approval for interconnect of two wind projects

Paulding Wind Farm III LLC, a wholly owned subsidiary of EDP Renewables North America LLC, applied Dec. 8 at the Ohio Power Siting Board for a certificate to construct a 138-kV transmission line with a point of interconnect (POI) switchyard (called the Timber Road III POI Switchyard).

The facility is associated with Timber Road I Wind Farm and Timber Road III Wind Farm, both located in Paulding County and both approved by the board in prior cases.

The primary purpose of the Timber Road III Transmission Line is to deliver electricity generated by the Timber Road I Wind Farm and the Timber Road III Wind Farm from the collection substation for the Timber Road III Wind Farm to the proposed Timber Road III POI Switchyard, to be located adjacent to the existing American Electric Power (NYSE: AEP) 138 kV Lincoln–Sterling circuit.

The Timber Road III POI Switchyard will not require a voltage step-up, and will not require voltage transformers. Due to the fact that the applicant’s queue position for this PJM Interconnection point totals 150 MW, the applicant will build out the switchyard to accommodate 150 MW. The applicant does not have specific future expansion plans; therefore, this Dec. 8 application focuses on the need to interconnect 100.8 MW of electricity from the Timber Road I Wind Farm and Timber Road III Wind Farm.

The Timber Road III Wind Farm collection substation will be located along Road 124 just west of intersection with Road 33 in Harrison Township. The Timber Road III Transmission Line will run south from the collection substation to the existing 138 kV Lincoln–Sterling circuit, where the proposed Timber Road III POI Switchyard will be constructed. 

The developer in conjunction with the PJM performed the System Impact Study on the wind farm interconnection request. This study was completed in June 2009, re-tooled in July 2012, and revised again in October 2015. Potential local AEP and overall PJM network impacts were evaluated for compliance with reliability criteria for summer peak conditions in 2013 in the following categories: Generator Deliverability, Multiple Facility Contingency, and Short Circuit Analysis.

The project schedule is:

  • Preparation of this application occurred in the fall of 2015, with data and analyses added as various studies were completed. A public information meeting was held Oct. 26, 2015.
  • It is anticipated that the certificate will be issued in the first quarter of 2016.
  • It is expected that final designs and detailed construction drawings will be completed in the first quarter of 2016.
  • Construction is anticipated to begin in the first or second quarter of 2016 and be completed within nine months, with completion of the project scheduled for approximately Nov. 30, 2016.
