Geothermal now accounts for 51 percent of the national power generation mix and has averaged 41 percent over the last six months . This has resulted in a decline in reliance on hydro and thermal sources leading to a reduction in the cost of electricity by more than 30 percent and a more reliable base ; at best hydroelectric stations can only run at around 70 percent efficiency whereas geothermal plants typically achieve over 90 percent . KenGen is not resting on its laurels ; by 2018 a further 460 MW of geothermal may be developed . If this is achieved , the amount of electricity generated by hydro power could be reduced to 28 percent of the total mix .

“ Our strategy now is to push forward with the projects that we have lined up , and in the next year or two we hope to bring in additional capacity of up to 385 MW , all from geothermal ”
