Who did NRG sell to?

I'm curious, who exactly did NRG Energy sell to? Was it a strategic investor looking to expand their renewable energy portfolio, or was it a financial buyer seeking to capitalize on NRG's assets? And what motivated NRG to make this sale? Was it a need for capital, a shift in their business strategy, or perhaps a desire to focus on other areas of their operations? I'd love to hear more about the details of this transaction and who the buyer was.
