Thunder Spirit Wind seeks market authority for North Dakota project

Thunder Spirit Wind LLC on July 24 asked that the Federal Energy Regulatory Commission authorize it to sell energy, capacity, and certain ancillary services at market-based rates and accept for filing its proposed market-based rate tariff.

Thunder Spirit is currently developing a 107.5-MW wind farm in Adams County, North Dakota, under an Asset Purchase Agreement (APA) with Montana-Dakota Utilities Co. Pursuant to the APA, Thunder Spirit is developing the project, and subject to the necessary regulatory approvals, Montana-Dakota will purchase the project either shortly before or shortly after it enters commercial operation. In the event Montana-Dakota fails to obtain the necessary regulatory approvals, Thunder Spirit said it will sell the project’s output to Montana-Dakota pursuant to a Power Purchase Agreement (PPA).

Thunder Spirit and Montana-Dakota anticipate that sales of “test energy” may occur before the expected closing date in the event that Montana-Dakota does purchase these assets. Whether the sales are for long-term or test energy, TSW will require market-based rate authority. Montana-Dakota and Thunder Spirit submitted their Federal Power Act Section 203 application for MDU to purchase the project on July 14.
