MISO files interconnect deal for 17-MW Duke solar project in Indiana

The Midcontinent ISO filed with FERC a revised Generator Interconnection Agreement, under Project No. J453, for a solar project of Duke Energy Indiana LLC.

On July 11, MISO had filed an unexecuted Generator Interconnection Agreement with Duke Energy Indiana LLC and Duke Energy Business Services LLC (on behalf of Duke Energy Indiana). The Duke GIA was filed unexecuted because the parties disagreed over the applicability of two of the milestones in Appendix B of the agreement, given Duke Indiana’s position as both interconnection customer and transmission owner.

Under this agreement, Duke Energy Indiana would install a 17.6 MVA facility, rated at 17.25 MW net, with all studies performed at or below these outputs. The facility is composed of eight photovoltaic arrays of SMA SC2200-US units, each rated at 2.2 MW, but configured to be limited at 2.156 MW. The Point of Interconnection (POI) will be at the point where the lead line from the solar facility lands on the 69-kV bus at the Crane Solar Substation.

The project has a target commercial operation date under the GIA of Feb. 8, 2017.

Notably, the Indiana Utility Regulatory Commission on July 6 approved an application from Duke Energy Indiana for a Certificate of Public Convenience and Necessity for the Crane Solar Facility. Duke would construct the Crane Solar Facility on land leased to Duke Energy Indiana by the Naval Support Activity Crane (NSA Crane) base. The project will be approximately 17 MW (ac)/24 MW (dc) in size. The Crane Solar Facility will interconnect to Duke Energy Indiana’s 69-kV transmission line located nearby and will be bid into the MISO market in the same way as other Duke Energy Indiana-owned generation.
