The U.S. electric transmission grid consists of more than 200,000 miles of high-voltage transmission lines (230 Kilovolts and greater).  Transmission lines carry electricity from power plants to areas where electricity is needed. Electricity travels at nearly the speed of light, arriving at a destination at almost the same moment it is produced. Reliable electric service and regional electricity markets depend on strong transmission systems. 

We Need to Invest in Transmission Now

As our country’s demand for electricity continues to increase, the system must be expanded and upgraded to meet the needs of our growing population and digital economy. In order to build the system to better meet current and future demand, to alleviate congestion, and to reinforce system reliability, electric companies have earmarked billions of additional dollars for investment in the coming decade.
