British power supplier Scottish & Southern Energy - the new owner of Airtricity - said its adjusted pretax profit rose 13.9% to £1.23 billion sterling in the year to the end of March, in line with expectations.
The company said in a statement it raised its full-year dividend by 10% to 60.5 pence a share, and it expected to continue a policy of dividend growth for the next decade.
SSE supplies gas and electricity to customers in Scotland and the south of England. It said it had gained an extra 700,000 customers during the year, bringing its total to 8.45 million and making it the UK's second-largest supplier of electricity and gas.
It has also begun targeting the Irish market, buying wind company Airtricity in January for over €1 billion.
