we are broke it's not business as usual we can sell anything available now

150 cars by 2020 will hardly impact overall power consumption

How much is one car's consumption for you to draw such a conclusion? And who's to say competitors will not jump in this adding to the number?

The Kenya Electricity Generating Company (KenGen) will now manage the 54.6 megawatts (MW) Garissa solar power plant.
Electricity from the plant will be sold to Kenya Power at Sh5 per kilowatt hour (KWh) - a low rate that is almost comparable to the cheapest source – hydro. KenGen yesterday said it is currently discussing the terms of operating the plant with REA. “REA has approached KenGen to run the 50MW solar plant in Garissa and negotiations are ongoing to establish the terms of the operations and maintenance contract,” said Rebecca Miano Chief Executive KenGen said in a statement.
REA and Kenya Power had initially signed a power purchase agreement that put the cost of the electricity from the plant at Sh10 per unit, but the Energy Regulatory Commission declined to approve it on grounds that the plant would be built by a State-owned entity using a concessional loan. Its pricing is in comparison to other planned solar power plants at Sh12 per unit. It is also in comparison to power from geothermal plants at Sh7 per unit. KenGen said managing the plant on behalf of REA fits into its strategy of partnering with other power producers.
