The production of electricity is not annualised,its measured in constant flow.
Hence in this case we say Mumias can supply 35MW per annum. (Thats what I meant by you cant store it)
Using your example,a nuclear power plant may give 1,000MW per hour in constant flow thoughout the year,
hence the output will be 1000x24x365 = 8,760,000 MW,now compare that to MsC
I hope that is now helpful.
I guess if you can't win with facts,you can always pen bile-laced,xenophobic rants to distract everyone.
