Bishop Hill II wind farm in Illinois nears commercial start

The new Bishop Hill II wind farm in Illinois, with a nominal 81 MW of capacity, is due for commercial operation by Nov. 30, said MidAmerican Energy Co. and related companies in a Nov. 21 filing at the Federal Energy Regulatory Commission.

In the filing, Bishop Hill Energy II LLC, Cordova Energy Co. LLC, MidAmerican Energy Co. and Saranac Power Partners LP (collectively, the “MidAmerican Parties”) submitted a notice of a non-material change in status from the characteristics relied upon by the commission in granting these entities market-based rate authority. Specifically, MidAmerican notified the commission of a change in status of certain MidAmerican and Bishop Hill II generation facilities. This change in status does not affect the results of the commission’s market power analysis when applied to the MidAmerican Parties.

The MidAmerican Parties are all indirect, wholly-owned subsidiaries of MidAmerican Energy Holdings, which is a subsidiary of Berkshire Hathaway (NYSE: BRK-A, BRK-B).

Bishop Hill II owns and operates a nominal 81-MW wind generating resource in Illinois within the Midwest ISO market area. Bishop Hill II completed construction of the Bishop Hill II wind facility on Nov. 19 and expects to achieve full commercial operation by Nov. 30. Bishop Hill II has entered into a 20-year power purchase agreement to produce energy and deliver Renewable Energy Credits totaling about 85% of the expected energy output of the Bishop Hill II wind facility. The balance of the output from Bishop Hill II may be sold into the MISO market. Bishop Hill II has been granted by FERC market-based rate authority and has filed a notice of self-certification of exempt wholesale generator status.

MidAmerican Energy Holdings subsidiary MidAmerican Renewables on March 30 said it had completed the acquisition of the 81-MW Bishop Hill II wind project from Invenergy Wind LLC.

The Nov. 21 filing noted that the MidAmerican Parties are also finalizing construction of these other new wind generation projects, all in the MISO market of the Central Region:

  • Eclipse Facility, (Audubon and Guthrie counties, Iowa), 200.1 MW (nameplate);
  • Morninglight Facility, (Adair and Cass counties, Iowa), 101.2 MW (nameplate); and
  • Vienna Facility, (Marshall and Tama counties, Iowa), 105.6 MW (nameplate).

By their nature, these facilities are placed in service gradually over a period of weeks or months as individual turbines are installed and commissioned, the filing noted.
