PG&E Corp. has lured away the top executive at Michigan's largest power provider. Patricia Poppe will leave her job as CEO of CMS Energy Corp. to take the same position at PG&E effective Jan. 4. Her hiring, announced Wednesday, comes nearly five months after the San Francisco company emerged from one of the most complex bankruptcy cases in U.S. history. She will replace interim CEO Bill Smith, who filled the void after Bill Johnson stepped down from the job after just 14 months.
