Trivia: Texas is the only contiguous state with its own what?
Postal service
Coast Guard
Power grid
Mountain range
Correct Answer: Power grid
So why is this answer correct? : The Lower 48 is home to just three power grids: the Western Interconnection, the Eastern Interconnection, and ERCOT (the Electric Reliability Council of Texas). Why does Texas have its own grid? ERCOT stemmed from a number of separate electric utilities that began to link together in the late 19th and early 20th centuries. When President Franklin D. Roosevelt signed the Federal Power Act in 1935, TIS remained independent in order to avoid federal regulation.
