Overview
Donnelley Substation is an operational electrical substation in the United States, owned by PPL and operating at 138 kV. It plays a role in regional grid stability.
Donnelley Substation is an operational electrical substation located in the United States, owned and operated by PPL. The facility operates at a voltage of 138 kV, which classifies it as a high-voltage substation critical for transmission and distribution of electricity. As part of PPL's infrastructure, it supports the regional power grid in Pennsylvania. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. The 138 kV voltage level is typical for sub-transmission systems that connect distribution networks to higher voltage transmission lines. PPL, as the owner and operator, adheres to NERC's Critical Infrastructure Protection (CIP) standards to ensure cybersecurity and physical security. Donnelley Substation contributes to the reliability of the local electrical grid, serving residential, commercial, and industrial customers in the area. Its operational status ensures continued power delivery and grid stability. The facility's location in Lancaster County, Pennsylvania, places it within a region with diverse energy needs, supporting both urban and rural communities.
Environmental context
The substation's location in Lancaster County, Pennsylvania, places it in a region with a mix of agricultural and urban land use. Electrical infrastructure like Donnelley Substation can have localized environmental impacts, including electromagnetic fields and potential effects on wildlife. However, modern substations are designed with mitigation measures such as shielding and habitat conservation. The facility's 138 kV voltage level is typical for sub-transmission, balancing efficiency with environmental footprint.
