SINGAPORE : The renewables unit of Portugal's largest utility, EDP, is in talks to sell power directly to Japanese and Korean companies as a way to boost growth in Asia, an official said, a departure from its traditional contracts with state entities. The unit, EDP Renovaveis SA (EDPR), aims to invest 21 billion euros ($23.12 billion) in renewables over the next four years, 80 per cent in North America and Europe, but is betting on deals with corporates to break into the Asia-Pacific region.
