Interconnected grid for energy security

Only an interconnected grid will save Nepal from power cuts in case of a calamity causing to lose a few hydropower plants.

On February 2021, the biggest state in the most developed country in the world, Texas, USA, faced an unprecedented event. Due to hurricane Uri, the Texas electricity grid was forced to shed a load, a lot of it. It left 4 million Texans without power for almost seven days. To the world’s dismay, the power cut killed approximately 246 Texans, as reported by the state; other reports are grimmer, with more than 700 hundred fatalities. The total economic loss was an astounding $125 billion. A state considered an energy powerhouse faced such devastation, but surrounding states affected by the same hurricane fared much better. Case in point, Oklahoma, which borders Texas from the north, was also hit by Uri, in similar strength, but only lost power for a few hours, and the grid was restored right after. More importantly, no lives were lost. Why were these two cases so different?
