Feb 7 (Reuters) - AGL Energy AGL.AX , Australia's largest power producer, reported a 10.3 percent rise in its half-year underlying profit helped by strong margin growth in wholesale markets and lower compliance costs in renewable energy markets.
For the six months to Dec. 31, underlying profit - which excludes one-off items - rose to A$537 million ($382.24 million) from A$487 million last year, the company said in a statement. The company declared an interim dividend of 55 cents a share, compared with 54 cents a year ago. ($1 = 1.4049 Australian dollars)
