Overview
Freyer Road Sub is a 69 kV substation operated by NIPSCO in the United States. It plays a role in regional electrical distribution and grid stability.
Freyer Road Sub is an electrical substation located in the United States, operated by NIPSCO (Northern Indiana Public Service Company). The facility operates at a voltage of 69 kV, classifying it as a sub-transmission or distribution-level asset within the broader electrical infrastructure network. As a substation operating under NERC reliability standards and FERC regulation, Freyer Road Sub is subject to mandatory compliance with grid reliability criteria. The 69 kV voltage level is typical for regional distribution systems that serve industrial, commercial, and residential loads, and the facility's equipment likely includes circuit breakers, transformers, and switchgear designed to ensure safe and reliable power flow. The substation's operational status indicates it is actively contributing to the local power grid. Its location in Indiana places it within the PJM Interconnection or MISO regional transmission organization, which coordinates grid operations across multiple states. The facility supports NIPSCO's service territory, providing electricity to customers in northern Indiana and enhancing grid resilience through voltage regulation and fault isolation.
Environmental context
The substation's location in a mixed urban-rural area of Indiana means it supports both residential and industrial electricity demand. The 69 kV voltage level is typical for distribution networks that may interface with renewable energy sources or backup generation. The facility's equipment, such as oil-filled transformers, requires proper containment to prevent environmental contamination. Its role in grid stability helps reduce the risk of power outages that could impact local communities and businesses.
Frequently asked questions
