Earnings from renewables at US company NRG Energy fell 14% to $66m in the third quarter of 2017, compared with $77m in the same period last year.
The segment made a net loss of $4m during the period, down from a profit of $2m last year.
NRG said the fall was due to lower solar generation at its Ivanpah solar thermal plant and higher operating expenses.
The company said it is continuing with its three-year transformation plan, which includes offloading its renewables assets.
NRG said it sold a 38MW solar portfolio to NRG Yield in addition to other projects it developed for $71m.
At the end of the third quarter, the company said it had realised $92m or 142% of its 2017 cost savings announced in the plan in July.
The plan aims to sell up to $4bn worth of assets.
Overall, earnings at NRG were down to $806m in the quarter from $895m in the same period last year.
However, profit was up in the third quarter at $190m, compared with $128m in 2016.
