What are transmission lines?

Transmission lines are high-voltage facilities that transport large amounts of electricity from power plants to communities. They are generally supported by tall structures (taller than the distribution lines along streets and in neighborhoods). The transmission system is a network of transmission lines that crisscross the state and links Florida's utilities with utilities in neighboring states, to ensure a reliable electric system.

Would a new power plant require new transmission lines?

Just as the state needs new sources of electric generation to meet significant population and usage growth, we also need to expand the transmission system to ensure a continuous, reliable supply of electricity for the region.

Any new baseload power plant in Florida would require an expansion of the electric transmission system to deliver large amounts of power from plants to communities. The specific transmission system expansion plan would be determined if and when a decision is made to move forward with building a new plant.

How much transmission expansion will be needed to support the Levy County plant?

If Progress Energy decides to build the Levy County nuclear plant, the company will need to build about 200 miles of new transmission lines. After a lengthy review process with significant public input, the company has selected a preferred route for the transmission lines that runs largely along the path of existing transmission lines. Only 20 miles of new easement would be needed. A schedule for construction of transmission lines will be determined after the company decides whether to proceed with the plant.

How does Progress Energy decide where to build transmission lines?

When deciding the best locations to build transmission lines, Progress Energy’s goal is to ensure reliable electric service while minimizing impacts on communities to the extent possible. The company evaluates numerous criteria and includes significant public input in the decision.
