PPL Electric Utilities of Allentown has submitted a proposal to build a $4 billion to $6 billion, 725-mile, 500-kilovolt transmission line from Western Pennsylvania into New York, New Jersey and Maryland.
PPL Electric Utilities submitted the proposal to PJM Interconnection LLC, the regional transmission organization that regulates part of the Eastern Interconnection electric transmission system in Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.
The company said the new regional transmission line that would make electric service more reliable and enhance the security of the electric grid while reducing the cost of electricity for consumers.
It said the project is in the preliminary planning stages. If approved and built as proposed, the line would help replace supplies of electricity that will be lost when existing power plants retire. It also would help prevent power shortages during periods of extremely high demand, like the prolonged severe cold weather this past winter.
"This is a forward-looking project with significant benefits for customers, for several states and for the region as a whole," said Gregory N. Dudkin, president of PPL Electric Utilities.
The company has begun a comprehensive regional planning effort to determine the best route and final details of the proposed line.
PPL Electric Utilities may enter into partnerships to develop and build some or all of the project, he said.
Based on the preliminary timeline the project would be complete sometime between 2023 and 2025, with construction beginning in 2017. Approvals are needed from various regulatory and regional planning entities before work could begin.
