Southern Power, the IPP subsidiary of Atlanta-based Southern Company, will buy a 51% stake in Roserock, which will be one of the largest solar projects in Texas upon its completion in late 2016.
Canadian Solar will retain a 49% stake in Roserock, which has a 20-year off-take contract with Austin Energy.
Canadian Solar’s plans for a yieldco wavered earlier this year as the share price of yieldcos like TerraForm Power and NextEra Energy Partners slumped.
