American Transmission Co. elects two new board members

PEWAUKEE, Wis. – Michael R. Niggli and Robert Foster joined the board of directors of American Transmission Co. Both men have had executive careers in the energy field for more than 40 years.

Niggli is the retired president and chief operating officer of San Diego Gas & Electric Co. and Foster is the retired president of Southern California Edison.

Niggli spent 30 years in leadership positions with Sempra Energy and its subsidiaries, including positions as COO of Southern California Gas Co. and president of Sempra Generation. Prior to joining Sempra, he was chairman of the board, chief executive officer and president of Nevada Power Co. He held the same titles at Sierra Pacific Resources after the merger of those two companies. The combined companies served most of the state of Nevada with electric transmission, distribution and generation as well as serving the northwestern portion of the state with natural gas and water service.

Foster began his career with the California State Senate Energy Committee and advanced to division chief and deputy director of the California Energy Commission prior to joining Edison. He was at the forefront of energy efficiency and renewables, pioneering California’s energy standards for buildings in the 1970s and leading Edison back to financial health after the state’s energy crisis. After retiring, he served as chairman of the California Independent System Operator and also served two terms as mayor of Long Beach.

“These two men had distinguished careers serving energy customers in the western United States and will provide valuable insight to ATC leadership as we pursue our vision to become American’s premier energy delivery partner,” said ATC President and Chief Executive Officer Mike Rowe. “We welcome them to our board.”
