Perez, a SunEdison veteran, was named COO of the company and its first yieldco, TerraForm Power, just nine months ago. He has also left TerraForm Power.
Tesoriere, who is managing principal at Atlai Capital, had served on SunEdison’s board of directors for more than three years. His invitation to the board in 2012, a previous crisis period for SunEdison, was at the time taken as a sign that SunEdison was becoming more receptive to the ideas and concerns of its investors.
