SunEdison Inc. is seeking bankruptcy-court approval to sell a number of North American solar- and wind-power projects to NRG Energy Inc. for $144 million, subject to higher bids.

SunEdison US:SUNEQ on Tuesday filed papers in its chapter 11 case outlining plans to auction its ownership stakes in the companies that construct large-scale renewable-energy facilities and sell wind or solar power to utility and other customers. The projects up for sale are located in Utah, California, Maine, Hawaii, Texas and Washington, court papers say.
