TOKYO, May 25 (Reuters) - Softbank Corp , Japan's third-largest mobile phone operator, said on Wednesday it plans to invest several percent of sales revenue in solar power.
"Our main business is telecommunications and there will be no change to that. But I think we can invest a few percent of our more than 3 trillion yen ($36.6 billion) sales revenue on renewable energy, as a way of contributing to society," company president Masayoshi Son told a news conference.
The company said earlier it would help to build about a dozen large solar power plants across the country in a bid to revive a battered home market for renewable energy.
The government confirmed a target on Wednesday for users in some areas to reduce electricity use by 15 percent to avoid power blackouts in the peak summer demand period as utilities struggle to make up for generating capacity knocked out by the March 11 earthquake and tsunami.
The target applies from July 1 to areas covered by Tokyo Electric Power Co , known as Tepco, which serves the capital and surrounding region, and Tohoku Electric Power Co , serving the devastated northeast region.
Chief Cabinet Secretary Yukio Edano told a news conference the target will be in place until Sept. 22 for areas served by Tepco and until Sept. 9 for those covered by Tohoku Electric. It will apply between 9 a.m. and 8 p.m. on weekdays. ($1 = 81.920 Japanese Yen) (Reporting by Isabel Reynolds; Editing by Michael Watson)
