The Midcontinent ISO on Oct. 27 filed with FERC an executed Amended and Restated Generator Interconnection Agreement with MidAmerican Energy as both the interconnection customer and interconnecting transmission owner.
MISO has designated this as the First Revised Service Agreement No. 2856 under MISO’s FERC Electric Tariff. MISO has designated this as Project No. J411 in its interconnection queue.
In October 2015, MISO filed an original interconnection agreement with Ida Grove Wind Energy LLC (then part of Invenergy LLC) as the project developer and MidAmerican Energy as the transmission owner. Since then, MidAmerican has purchased the assets of Ida Grove and been assigned the original agreement.
Project J411 is a 300 MW net facility comprised of fourteen General Electric 1.79-MW wind turbine generators (WTGs) nominally rated at approximately 1.79 MW each and one hundred twenty GE 2.3-MW WTGs nominally rated at approximately 2.3 MW each. The Point of Interconnection is within MidAmerican’s 345-kV Ida County Substation.
The targeted commercial operation date for Ida Grove under the revised GIA is Dec. 15, 2016.
Says the MidAmerican website: "Construction continues on the Ida Grove and O’Brien wind farms, which will add up to 552 megawatts of wind generation capacity to the existing fleet. The project is on schedule to be complete by year-end 2016. Plans call for approximately 134 turbines and up to 301 megawatts of generation capacity at the Ida Grove wind farm, and approximately 104 turbines and 250 megawatts of generation capacity at the new O’Brien wind farm."
