In the next decade, a large percentage of municipalities throughout the country will experience power failures if they do not modernize their electrical substations
An electrical substation fails when the current it handles rises above its maximum capacity.
 The vast majority of substations in the country already handle currents between 60% and 80% of their maximum capacity, and currents are expected to rise, perhaps by as much as a factor of 3 in the next decade, because of population increase and the increased demand from both industry and electronics in individual homes
