Wall Street Sours on $9 Billion Mechanism for Green Projects
Wall Street investors have gone cold on one of the main mechanisms banks invented to fund the green-energy revolution. The business structure, known as the yieldco, feeds dividends from operating solar and wind farms to investors. Yieldcos raised $7.9 billion in public equity in 2014 and 2015 but only $1 billion since then, according to Bloomberg New Energy Finance. The shift is further fallout from the collapse of yieldco promoter SunEdison Inc. and has changed the way clean-energy developers finance themselves. In years past, they started yieldcos to buy projects once they were operating, recycling the capital into new installations. Now, they’re turning to a large and deepening pool of buyers — insurance companies and pension funds — to provide funding and sometimes take control of income-producing assets.
