The Midcontinent Independent System Operator (MISO) on Dec. 12 submitted to the Federal Energy Regulatory Commission an unexecuted Generator Interconnection Agreement among Tatanka Wind Power LLC, Montana-Dakota Utilities Co. and MISO.
The agreement updates an existing Large Generator Interconnection Agreement from for Project No. G132 based on the interconnection customer’s request to increase capacity with Project No. J249.
This North Dakota project currently has 180 MW of combined Energy Resource Interconnection Service (ERIS) and Network Resource Interconnection Service (NRIS) where NRIS cannot exceed 36 MW. After the completion of the upgrades, the NRIS amount will increase to 108.2 MW.
As part of its restudy for the capacity increase, MISO said it determined that seven transmission projects listed in its Midwest Transmission Expansion Plan (MTEP) should be included as contingencies in this agreement that need to be in service before the increase in NRIS could be granted. Tatanka Wind Power disputes the inclusion of two of these projects.
This wind facility is composed of 120 turbines in a wind farm rated at 180 MW (net) at the point of interconnection. The interconnection service is 180 MW of ERIS and NRIS where NRIS shall be up to but cannot exceed 36 MW until the 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 108.2 MW.
The existing generating facility’s commercial operation date was in July 2008.
