Hawaiian Electric Co. President and CEO 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. 

 “In 2008, I made the decision to come out of retirement for the challenge of leading an organization embarking on an unprecedented slate of clean energy initiatives,” Rosenblum said Tuesday. “Today, thanks to collaborative efforts with many partners, our utilities are meeting more than 18 percent of our customers’ energy needs with renewable energy, compared to just 8 percent in 2008.  We lead the nation in rooftop solar photovoltaic systems per customer, and we’re broadly recognized as an industry leader in the integration of renewable energy.”

 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.
