Wind farm operator Greencoat Renewables has reported a €3.9m loss between the middle of February and the end of September.
Greencoat Renewables said it made an operating profit of €9.8m in the period but the cost of finance pushed it into the red.
Greencoat operates wind farms in Cork and Tipperary, which it acquired in March for €318m.
The company had raised €270m when it listed on the Irish and London stock exchanges in July.
It said it expects to pay a dividend of 2.61 cent per share next March - in line with its stated initial target.
Greencoat said that evidence from the past six months has only increased its confidence in the outlook for Ireland's secondary wind market.
"Wind remains the dominant renewable technology and the group is in a good position to benefit as electricity production from wind becomes an increasingly important part of Ireland's generation mix," commented the company's chairman Rónán Murphy.
Mr Murphy said the total market of operating wind farms in Ireland is expected to reach €8 billion by 2020.
"The supply of operating Irish wind farms coming to market is increasing and the group has a significant pipeline of opportunities," he added.
