Major power failure across New Providence

I really don't understand why there are electrical engineers at B.E.C. and no one knows how to perform a power system analysis on Nassau's transmission system. They are bringing in four consultants to advise them of their problems. The electrical engineers at B.E.C need training in softwares such as ETAP and CYME so they can fully understand the transmission system and the problems that are occurring. Obviously a short in the high voltage capable means that the loads are exceeding the ampacity of the cable. This can be prevented by regularly performing a short circuit analysis on the clifton pier substation infrastructure since out network is 132kV/69kV. If the generators are switching on and off to protect themselves it means they need to upgrade their differential protection scheme at the substation. if they did that then could have performed arch flash studies to improve their antiquated systems hence prevent the "blowing up" of 5 generators due to the lightning strike. Since generators are nonlinear loads they inject harmonics into the grid and so when a load shedding happened it can cause the consumers equipment such as electronics to malfunction. What's beyond me is that the government can spend 20 million dollars on a building but they can't upgrade the current electrical transmission system. If the transmission system becomes more reliable then the next step would be solar integration.

Well an African proverb says "Ignorance will not kill you but it will make you sweat a lot" ..B.E.C is sweating profusely!!!

BEC foresees no power disruptions this week

It is not April 1st. why is the Tribune giving us a story that is obviously a joke? On a serious note how about doing a story on how much the incompetence of BEC is COSTING the country? How much money is spent on generators, fuel, upkeep, lost productivity, and the like. Has to be in the MILLIONS. BEC is a drag on the Bahamas,, there is no doubt about that! Another GOVERNMENT FAIL, red and yellow.
