The Midcontinent ISO (MISO) on Dec. 30 filed with FERC a generator interconnection agreement with MidAmerican Energy as both the interconnecting transmission owner and the developer of the 500-MW Orient wind project.
MISO has designated this as Project No. J500 in its interconnection queue. The project site is around the town of Orient in Adair County, Iowa.
This facility is rated at 500 MW net. It is to be composed of 250 Vestas V110 2.0 MW wind turbines. There will be three groups, each with approximately 83 to 84 turbines, with each group having their own generator step up transformer. Interconnection service provided under this agreement is 500 MW of Conditional ERIS and/or NRIS where NRIS is limited to zero once all Interconnection Studies are complete and all Network Upgrades are in service.
The Point of Interconnection will be at the point within MidAmerican’s 345-kV Orient Substation. The targeted commercial operation date for the project under the GIA is Dec. 15, 2019.
