Potomac Expansion Project

During the past 50 years Williams' Transco pipeline has been quietly, safely and reliably delivering natural gas to its customers through its 10,500-mile pipeline system, extending from Texas to New York.

The Transco pipeline is a major transporter of natural gas in the Mid-Atlantic region, delivering about 25% of the natural gas consumed in Virginia and 10% of the natural gas consumed in Maryland.

Demand for clean-burning natural gas in this region is steadily increasing. Clean-burning natural gas has become the fuel of choice for homeowners, businesses and electric power generators searching for ways to reduce air pollution. Natural gas is the cleanest burning fossil fuel. Used in place of other, more polluting energy sources it can help improve the air quality.

Williams is planning to expand its existing Transco pipeline to help meet the region's growing need for clean energy. Known as the Potomac Expansion, this project is being designed to create additional pipeline capacity by November 2007.
