Southwest Power Pool on Jan. 17 filed an executed Affected Systems’ Facilities Construction Agreement (FCA) with the Federal Energy Regulatory Commission related to a wind farm project in Osage County, Okla.
The FCA is between SPP as transmission provider, Osage Wind LLC as interconnection customer and the Grand River Dam Authority (GRDA) as transmission owner. This revised deal modifies and supersedes the FCA between the parties accepted by the commission in October 2011.
Osage Wind and Associated Electric Cooperative (AECI) have entered into an interconnection agreement (Osage Wind IA) to facilitate the interconnection of Osage Wind’s 150-MW generating facility to AECI’s transmission system. AECI is not a member of SPP, but AECI’s transmission system is interconnected to GRDA’s transmission system, which is under SPP’s functional control.
Based on a study, SPP determined that as a result of the interconnection of this facility to AECI’s transmission system, a network upgrade is required on the GRDA transmission system. While the Osage Wind IA governs the interconnection of the generating facility to AECI’s transmission system, including specifying any upgrades required on that system, it does not address the network upgrade needed on the GRDA transmission system.
Since the October 2011 FERC approval order, the parties have amended Appendix A of the original Osage Wind FCA to update the cost estimates and construction schedule, with the new transmission upgrades now due to be complete by June 2014, which is a roll-back from the originally planned completion in December 2012.
