The Southwest Power Pool on Jan. 8 filed at the Federal Energy Regulatory Commission an executed Interim Generator Interconnection Agreement (IGIA) for a wind project that was due for commercial operation at the end of 2013.
The IGIA is among SPP as transmission provider, Steele Flats Wind Project LLC as interconnection customer, and Nebraska Public Power District (NPPD) as transmission owner.
The Steele Flats Interim GIA allows Steele Flats to interconnect the up-rated facility to SPP’s transmission system on an interim basis. Steele Flats requested interim interconnection service because the facility is projected to be in service prior to the completion of applicable interconnection studies. SPP determined that providing interim interconnection service to Steele Flats’ Facility is feasible at this time, subject to the standard conditions in the pro forma Interim GIA.
In October 2013, Steele Flats commenced operations of a wind facility consisting of twelve GE 1.6-MW wind turbines and thirty-two GE 1.7-MW wind turbines for a total of 44 turbines with 73.6 MW of installed capacity. By increasing the rating of the twelve GE 1.6-MW existing wind turbines to 1.7 MW for an incremental capacity increase of 1.2 MW in total, there was an increase in the combined output of the forty-four turbines that constitute the wind energy generating facility to 74.8 MW.
The Point of Interconnection is the 115-kV bus of NPPD’s Steele City 115-kV substation.
In an Oct. 11, 2013, statement about why it didn’t sign for some new wind capacity, NPPD pointed out that it will have 312 MW of wind on its system by the end of 2014, and based upon current load demands, expects to have a total of 357 MW by the end of 2014 with two new wind farms either under construction or planned. The 75-MW Steele Flats Wind Farm near Steele City is expected to be in service in November 2013, it said, and the 75-MW Broken Bow II wind farm northeast of Broken Bow is anticipated to be in operation in late 2014.
