Goldman Sachs Group Inc. said Monday that it plans to invest as much as ¥50 billion in renewable energy projects in Japan in the next five years, tapping demand for electricity produced from solar and wind-power generators.

The Wall Street firm also plans to take as much as ¥250 billion in bank loans and project-financing over the same period to move ahead with projects that would cost a total of ¥300 billion, said Hiroko Matsumoto, a Tokyo-based spokeswoman for Goldman.

Japan began offering incentives in July through feed-in tariffs to encourage renewables amid the Fukushima nuclear crisis. Japan has been forced to slash its reliance on atomic power since the crisis started.
