NAIROBI (Reuters) – Kenya’s main electricity generator KenGen said on Monday its pretax profit for the full year to June rose 109 percent to 8.69 billion shillings ($84 million), helped by higher electricity sales.

KenGen, which is 70 percent state-owned, said in a statement its performance was boosted by increased generation from geothermal and wind power.

“Profit before tax increased … propelled by capacity growth, improved performance and tax credit from capital allowances enjoyed by the company following the commissioning of 280 MW geothermal plants, well heads and Ngong Wind,” it said.

It said electricity revenue jumped to 25.6 billion shillings from 17.4 billion the year before.

Earnings per share rose to 5.24 shillings from 1.29 shillings during the year to June 2014 and it said it would pay a dividend of 0.65 shillings per share, up from 0.40 shillings previously.

Operating costs rose to 8.41 billion shillings from 7.02 billion due to operating and maintaining new plants.

KenGen said in July it planned to add another 450 megawatts (MW) to the grid from wind and geothermal in the next three years at a cost of at least $710 million. [ID:nL8N0ZN29V]

Kenya, which depends heavily on renewables such as geothermal and hydro power, aims to expand installed capacity to about 6,700 MW by 2017, from about 2,500 MW now. It also aims to halve bills from between $0.17 and $0.18 per kWh within three to four years.
