Fun Facts
- How outdated is our power grid? The U.S. Department of Energy found that 70% of U.S. transmission lines are more than 25 years old in its last network-infrastructure review in 2015. Lines typically have a 50-year lifespan. The average age of large power transformers, which handle 90% of U.S. electricity flow, is more than 40 years.
- The first commercial power grid was first established by Thomas Edison in 1882.
- There are not one but three separate grids that supply power through the country. The three grids work independently from each other with some small links connected in a few places. The three grids include the:
- Texas Interconnected System
- Western Interconnection
- Eastern Interconnection
- There are around 120,376 linemen working the US grid at the moment with the career rate growing 1.94% each year.
- The number one cause of power outages in the US is severe weather. This results in approximately $33 billion dollars of repair each year depending on severity.
