New Jersey-based NRG is among the largest independent power producers (IPPs) in the US, with more than 50GW of generating capacity, and – alongside its yieldco, NRG Yield – one of the country’s largest owners of both solar and wind assets.

Amid challenging conditions for US IPPs brought on by low commodity prices, NRG’s quarterly loss widened substantially to $276m, from a loss of $9m in the same quarter last year.
