Competitive energy supplier NRG Energy closed on its acquisition of bankrupt SunEdison's solar and wind projects, adding more than 1,500 megawatts to its 50,000-megawatt portfolio. 

It's the final act in the dismantling of the once high-flying, self-proclaimed "renewable energy supermajor."

In 2014, SunEdison jumped into deep YieldCo waters with TerraForm Power and TerraForm Global. The company made a series of large, questionable acquisitions in First Wind and Vivint, as well as a slew of lesser corporate additions. SunEdison lost almost $1 billion in the first three quarters of 2015. When SunEdison's stock was at its peak, the company raised debt rather than equity -- and that debt load returned with a vengeance.

NRG is gaining a big chunk of SunEdison's portfolio and boosting its own utility-scale portfolio. Despite NRG's difference of opinion with its fired CEO, renewables champion David Crane, the company is not abandoning renewables. It continues to replenish projects for YieldCo partner NRG Yield.

According to a blog post, the acquired portfolio includes:

  • Joint ownership in a 530-megawatt fully built and contracted set of seven utility-scale solar projects in Utah 
  • Ownership of 154 megawatts of fully contracted, partially constructed solar projects in Texas
  • Ownership of 1,100 megawatts of solar and wind assets across the U.S., including 111 megawatts of construction-ready assets in Hawaii

The contract with SunEdison provides for up to $183 million in payment, comprising an upfront payment of $124 million and subsequent payment of $15 million after the power-purchase agreements in Hawaii are closed. NRG may pay another $44 million if certain project benchmarks are met.

Outside of SunEdison’s federal bankruptcy court process, NRG also acquired a 29-megawatt portfolio of in-construction and construction-ready distributed solar projects.

Here's an updated SunEdison timeline.
