TerraForm Power shares rose 6.7 percent to $13.34 in light premarket trading on Monday.
All Class B shares of TerraForm Power are owned by SunEdison, while its Class A shares are held by the public, private investors and the company's executives.
TerraForm Power had 80 million Class A shares and 60.4 million Class B shares outstanding as of Oct. 31, 2015.
The rights plan is also aimed at fending off Brookfield Asset Management's accumulation of its Class A shares, TerraForm Power said in a statement on Monday.
Separately, SunEdison said it was working with TerraForm Power and its other yieldco, TerraForm Global Inc <GLBL.O>, to explore "value creation options" for their Class B shares it holds.
The rights plan, popularly known as "poison pill", will be triggered if a party takes 15 percent ownership of TerraForm Power.
Brookfield Asset Management and Appaloosa own 12.13 percent and 9.54 percent of TerraForm Power's class A shares, respectively, according to a filing.
