Earning before interest, tax, depreciation and amortisation (Ebitda) also grew 6.7% to €392 million year-on-year.
The Spain-based renewable developer said its domestic business grew 8.9% due to an 11% production increase, despite a small fall in wholesale prices, the company said.
Internationally, Acciona Energia achieved a 4.8% increase in revenues with production up 14%.
Production was boosted by the 359MW of wind added in Mexico, India, Australia and Canada, which offset the 299MW reduction of renewables capacity in Spain.
As a group, Acciona made €186 million in net profit, up 132% year-on-year, and Ebitda grew 6.7% to €618 million.
