South Dakota regulators to hold hearing on proposed 230-kV generation tie line, substation

The South Dakota Public Utilities Commission, in an Oct. 31 order, said that it will hold a public input hearing on Dec. 6 in Milbank, S.D., on an application that involves a proposed 230-kV generation tie line.

As noted in the order, the commission received on Oct. 27 a facility permit application from Crowned Ridge Wind, LLC, which proposes to build a new reactive power compensation substation and an approximately 34-mile, 230-kV generation tie line that will connect two 300-MW wind projects – Crowned Ridge Wind (CRW) and Crowned Ridge Wind II (CRW II) to the Big Stone South substation owned by Otter Tail Power (together, the substation and tie line are referred to as the project).

The planned Crowned Ridge Wind facilities will be permitted separately and are not included as a part of the project, the commission noted.

The generation tie line will be located in Codington and Grant counties in South Dakota, while the new reactive compensation substation will be located in Grant County, the commission said.

The project is expected to be in service by Dec. 31, 2019, and Crowned Ridge estimates the total construction cost to be about $30m for the single-circuit option, and $40m for the double-circuit option, the commission said.

Following the public input hearing, the commission may schedule a formal evidentiary hearing to consider any issues raised by any intervening party, the commission’s staff, or the commission itself.

Among other things, the commission added that for approval, Crowned Ridge must show that the proposed project will comply with all applicable laws and rules; will not pose a threat of serious injury to the environment nor to the social and economic condition of inhabitants or expected inhabitants in the siting area; will not substantially impair the health, safety, or welfare of the inhabitants; and will not unduly interfere with the orderly development of the region with due consideration having been given to the views of governing bodies of affected local units of government.
