The Shakopee Mdewakanton Sioux Community (SMSC) contracted Wind Decommissioning Service, LLC (Wind Decom) who then, in turn, contracted with Controlled Demolition, Inc. (CDI) to assist them in the energetic felling of a redundant 78-meter wind turbine unit that failed to reliably deliver power to the community and Casino facility at Mystic Lake.
CDI's energetic felling method was selected over crane dismantling to eliminate risk of personnel working at high elevations for an extended period, or the risks associated with mechanical tripping with cables that would have put demolition personnel and guests at the adjacent SMSC golf facility at risk from premature collapse, breaking cables, and fly of debris upon impact of the Unit at grade.
CDI prepared the unit for felling in less than five (5) hours the afternoon of June 20, 2022, placed a small quantity of explosives the morning of June 21st, and felled the unit in ten (10) seconds within a 30-minute security window. There was no damage to the golf course infrastructure or interruption of service from the Casino switchyard located less than 100’ from the base of the wind turbine unit. There was no need to evacuate residential properties as close as 970’ away.
