Point of Common Coupling Requirements

Interconnection Technical Requirements The following is a list of required details and components to include in your one-line diagram submission to PPL.
One-line Display Standard
PCC and Intertie Devices 
Technical Requirements 
This document specifies the PCC protective device necessary based on the size of the customer’s DER system and the configuration of the facility. A PCC protective device is typically required for DER sized 500 kW and larger to protect the PPL Electric distribution system and other customers from a potential fault caused by the customer’s facility.  Applies for applications before 9/1/23

Relay and Control Requirements 

This document specifies the relaying requirements necessary to accommodate large customer-owned DER, typically for system sizes 500 kW and greater. Relaying is required for larger DER systems to monitor performance during abnormal feeder conditions, and in some cases, disconnect the DER system to prevent an unintentional island from being sustained.

SCADA Requirements for Parallel Operation of Distributed Generation

This document standardizes the SCADA interfaces between PPL Electric system operations and the DER protective relays and monitoring equipment, which are customer-owned and PPL Electric-controlled. The requirements stated in this document only apply when SCADA is required per the “Relay and Control Requirements For Parallel Operation Of Distributed Energy Resources REV. 2” document.
