"This repair seemed to have possibly been performed in violation of a 'do not repair' order that Xcel Energy had issued on Dec. 31, 2021, to preserve the system until a cause and origin investigation could be completed," the investigative summary reads. "... The Xcel Energy employees involved in the repair process eventually participated in voluntary interviews with investigators. Those interviews, and all other available documentary evidence, indicates that Xcel repaired the disconnected line on Jan. 2, 2022, solely to restore power to customers."
