Interstate Energy Company, PPL’s oil and natural gas pipeline company, operates and maintains an 84-mile pipeline that transports oil from Marcus Hook, Pa., south of Philadelphia, to PPL’s Martins Creek and Lower Mount Bethel generating facilities in Lower Mount Bethel Township, Pa.
The dual-use pipeline can transport oil or natural gas through the same lines. This allows PPL Generation to choose the most cost-effective fuel to operate its electricity generating facilities.
Because of its dual use, Interstate Energy Company is regulated by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration while transporting oil and Pennsylvania’s Public Utility Commission while transporting natural gas.
Interstate Energy Company’s 18-inch mainline was converted for dual use in 1996. The line delivers oil by pumping liquids from the Marcus Hook Pump Station near Philadelphia to the Martins Creek Terminal, which can store 1.9 million barrels of oil.
Once the storage tanks are filled to the desired capacity, the pumps at Marcus Hook are shut down. Nitrogen is then pumped into the pipeline to remove the residual oil out of the line to prepare it for natural gas delivery.
PPL Interstate Energy Company is a subsidiary of PPL Generation LLC.
