Beethoven Wind project in South Dakota nears its commercial target date

NorthWestern Corp. d/b/a NorthWestern Energy filed on March 16 at the Federal Energy Regulatory Commission an Amended and Restated Standard Large Generator Interconnection Agreement with Beethoven Wind LLC for a 130-MW project in South Dakota.

NorthWestern Energy is a public utility engaged in the generation, transmission, and distribution of electricity and the supply and transportation of natural gas. Its facilities are located primarily in Montana and South Dakota.

In January 2014, NorthWestern Energy and B&H Wind LLC executed a non-conforming LGIA, which was filed with and accepted by the commission. In September 2014, NorthWestern provided written consent to the assignment of this LGIA to Beethoven Wind LLC. The parties have now mutually agreed to modify the milestones in Appendix B to accommodate new project schedules and to modify Appendices C and G to clarify the customer’s power factor requirements. In addition, several updates have been made throughout the agreement.

The facilities at the Point of Interconnection for this project are the Tripp Junction 115-kV Substation, which are included in the Western Area Power Administration/Basin Electric Power Cooperative/Heartland Consumers Power District Integrated System The commercial operation target date is April 25, 2015, which is a change from Nov. 1, 2014, in the original agreement. This is, under this revised LGIA, a 130-MW project made up of 71 General Electric wind turbines with 1.85-MW of capacity each.

Beethoven Wind LLC on Feb. 20 asked FERC to authorize it to engage in the sale of electric energy, capacity and ancillary services at market-based rates. Beethoven said in that filing that it will own a wind facility with a nameplate capacity of 79.55 MW located in Bon Homme, Hutchison and Charles Mix counties, South Dakota. The facility is currently under construction, and Beethoven said it expected to begin generating and selling test energy from it as early as Feb. 27.

Beethoven is a wholly owned subsidiary of BayWa r.e. Wind LLC (BayWa Wind). BayWa Wind is owned 95% by BayWa r.e. USA LLC (BayWa USA) and 5% by Florian Zerhusen, the President and CEO of BayWa Wind. BayWa USA is a wholly owned subsidiary of BayWa r.e. renewable energy Gmbh, a company organized under the laws of Germany (BayWa Gmbh). BayWa Gmbh, in turn, is a wholly owned subsidiary of BayWa AG, also a company organized under the laws of Germany.

The BayWa website also classifies Beethoven as a 79.55-MW project, made up of 43 GE turbines of 1.85-MW apiece.
