The Midcontinent Independent System Operator on Feb. 12 filed with the Federal Energy Regulatory Commission an Amended and Restated Generator Interconnection Agreement with Tatanka Wind Power LLC and transmission owner Montana-Dakota Utilities.
“This Interconnection Agreement increases the Interconnection Customer’s Network Resource Interconnection Service (‘NRIS’) to 180 MW pursuant to the Definitive Planning Phase 2012 August West Area Restudy dated October 1, 2014,” said the filing.
The generating facility is composed of 120 wind turbines in a wind farm rated at 180 MW net at the point of interconnection. The interconnection service is 180 MW of Energy Resource Interconnection Service (ERIS) and NRIS where NRIS shall be up to but cannot exceed 36 MW until certain MISO Transmission Expansion Planning (MTEP) upgrades are in service which is presently estimated to occur in 2015. After completion of the MTEP upgrades, the interconnection service shall become 180 MW of ERIS and NRIS where NRIS shall be up to but cannot exceed 180 MW. This facility’s original commercial operation date was in 2008.
Said the ACCIONA website about this facility: “Tatanka Wind Farm is the largest renewable-energy project in North and South Dakota, sitting on approximately 14,080 acres. Tatanka represents the first installation of ACCIONA’s 1.5 MW turbines in the U.S. There are 120 wind turbines spread over the wind farm, with 59 turbines located in South Dakota and 61 turbines in North Dakota.”
