Market ‘Saturated’ by Yieldcos After 15 IPOs, Says NRG Yield CEO

There may be too many renewable-energy holding companies, according to David Crane, chief executive officer of NRG Yield Inc., one of the first of these ventures to sell shares in an initial public offering.

The growing number of these companies, often called yieldcos, is driving up competition to buy wind and solar power projects and boosting prices, said Crane, who’s also CEO of NRG Energy Inc., the largest independent U.S. power producer, which controls NRG Yield.
