TOKYO -- Marubeni will purchase a Taiwanese renewable energy company that is developing one of the world's largest offshore solar farms, seeing an opportunity in a market trying to wean itself off nuclear power. The Japanese trading house will spend more than 10 billion yen (or over $100 million) for a 100% stake in Chenya Energy as well as its power generation facilities with a total capacity of 270,000 kW. This marks Marubeni's first investment in renewable energy plants on the island.
