If no buyer is found, the project could be re-bid, the industry sources said. SunEdison did not respond to multiple requests for comment. "The tariffs are a tad aggressive and that may not be healthy for developers themselves and also for others in the ecosystem … manufacturers and financiers," said Santosh Kamath, head of renewables at consultancy KPMG India. "That might be a warning signal for the industry." SunEdison's troubles notwithstanding, India has attracted deep-pocketed investors to its $100 billion solar energy program — the biggest in the world. Japan's Softbank (SFTBY), Taiwan's Foxconn (HNHPF) and India's Bharti Enterprises have separately pledged to invest a total of about $20 billion in India's renewable sector. Global solar giants like First Solar(FSLR), Trina Solar (TSL) and Finland's state-controlled utility Fortum Oyj are also expanding their presence.
