Hawaiian Electric Co. President and Chief Executive Officer Richard Rosenblum has notified the company that he plans to retire within a year.

Rosenblum, 64, has headed up the state’s dominant utility since 2009. He joined the company after a 32-year career at Southern California Edison.

Connie Lau, chairman of HECO and CEO of parent company Hawaiian Electric Industries Inc., said she is working with Rosenblum and his team on the ongoing energy planning process as well as the future leadership transition.

"We’ve been fortunate to benefit from Dick’s exceptional knowledge and operational expertise," Lau said. "His passionate focus on improving customer service and reliability, instilling a pervasive culture of safety for our employees and our customers, reducing our dependence on expensive imported oil, and building our talent and management strength has laid a solid foundation for our utilities."
