Transmission Services

(Transmission entity or end user)

As of April 1, 1997, transmission service on PPL Electric Utilities facilities is provided under the PJM Open Access Transmission Tariff and is administered by the PJM Interconnection, L.L.C. The PPL Electric Utilities’ documents listed below address the requirements for the interconnection of generation, transmission, and end user facilities to the PPL Electric Utilities’ transmission system in Pennsylvania. All interconnected facilities must meet these requirements.

If the developer wishes to investigate or pursue the "Option to Build”, there are additional standards and requirements with which the developer must comply. These additional requirements can be made available to the developer upon request.
