PIERRE, S.D. — The South Dakota Public Utilities Commission approved a temporary and conditional waiver that would allow an energy company more time to install low-noise trailing edge attachments on turbine blades in wind farm project located in Grant County and Codington County.

Representatives from NextEra Energy Resources, which is involved with the Crowned Ridge Wind project, requested the waiver so the attachments could be installed this summer. The project’s completion date is scheduled for Jan. 1, 2021.

The waiver will allow the company to install the low-noise trailing edge attachments by Sept. 15.

The company has attached eight of the 87 wind turbines with low-noise attachments. Of those 87, the company will need to attach 79 turbines with low-noise attachments by the Sept. 15 deadline.

Joshua Tran with NextEra and chief engineer of the Crowned Ridge Wind project told commissioners that weather conditions needed to be 50 degrees or greater in order for the glue to properly adhere the attachments to the wind blades.

Commissioners Kristi Feigen and Chris Nelson voted in favor of approving the waiver. Commission Chairman Gary Hanson voted against.
