Iberdrola renewables earnings before interest, tax, depreciation and amortisation were up over 13% in the first quarter of 2019, compared with the same period last year.
EBITDA stood at €683.6m, while revenue also grew to over €1.1bn – a 5% increase the company said.
Iberdrola said the contribution of its renewables businesses in Brazil, Mexico and the UK, as well as the offshore sector – particularly the Wikinger project – were behind the increases.
These contributions more than offset lower production in the US and Spain, it added.
Offshore output was up 58% in the period to 643 gigawatt-hours from 407GWh last year, despite installed capacity remaining the same.
Power prices also helped the company’s results in the first three months of the year with the average price at €73.5 a megawatt-hour.
Average operating power during the period was up 87MW on last year to 26,853MW.
It was boosted by new solar capacity in Mexico (270MW) and onshore wind in the US (over 160MW), as well as Wikinger contribution in the offshore market, the company said.
In the UK, Iberdrola noted that 37 jacket foundations have been installed at the 714MW East Anglia 1 offshore wind farm, with all the piles for the 102 turbines in place.
The remaining foundations are expected to be installed in the third quarter of the year.
The first turbines and first power is scheduled for the end of the second quarter, the company said.
Onshore work on the substation at Bramford is drawing to a close, it added.
Manufacture and installation of the first offshore cable has been finalised, with the installation of the second cable planned for the summer.
