MELBOURNE, Sept 9 (Reuters) - Origin Energy ORG.AX , Australia's top power and gas retailer, on Friday promoted energy markets chief Frank Calabria to replace long-time Chief Executive Grant King, just as the company weighs whether to spin off its gas production business.
King, long a market darling, has led Origin since it was spun out from Boral Ltd BLD.AX in 2000 and headed the energy arm of Boral from 1994. Calabria will take over from Oct. 19.
