Transmission lines are the high voltage conductors that move electricity from power plants to distribution systems, which deliver power to customers. Adequate transmission capability is essential for electric reliability and to serve growing population and foster economic growth. Transmission lines are typically built to connect new power plants, (including renewable energy generators), to accommodate power flow from generation or load changes and to reduce congestion on the electric grid, which can impact energy costs. Transmission lines help ensure the continued safe, reliable and efficient delivery of electricity to homes and businesses.
