The Importance of Transmission Capacity

Increasing transmission capacity is critical for the successful transition to clean energy in the U.S. Currently, there is approximately 2.5 terawatts of renewable energy, including wind and solar, that cannot be integrated into the grid due to insufficient transmission infrastructure. The need for expanded capacity is rooted in the historical development of the transmission system, which was primarily designed to support fossil and nuclear resources. To fully utilize the vast renewable energy potential across the country, significant upgrades to the transmission network are essential.
