Does that statement make sensible economic sense? Now Kenya does not produce natural gas so the Gas turbines will most likely be fired from the same diesel fuel the Aggreko ICE were using...we cannot also use cheap HFO since we dont have crude oil locally available cheaply. Techinically,comparing an apple for an apple, Gas turbines are more hungry than ICE when using the same type of fuel. #Home science graduates can skip this discussion. Where?

Do the math and tell us, how much energy do you extract from LNG 4 same unit cost as diesel Kilo for Kilo, LNG has more energy density than DSL. But we cant opt for it since we dont have natural gas readily available and the cost of buying and transporting it will largely outweigh that of DSL cost!
