Willard Green Substation - Hoosier Energy 69 kV Substation in Indiana

Willard Green Substation is an operational electrical substation located in Indiana, United States. Owned and operated by Hoosier Energy, a generation and transmission cooperative, the facility plays a critical role in distributing electricity across the region. The substation operates at a voltage of 69 kV, which is typical for sub-transmission and distribution-level infrastructure in rural and suburban areas. As part of the U.S. electrical grid, Willard Green Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability, cybersecurity, and compliance with mandatory reliability criteria. The substation likely includes switchgear, transformers, and protection systems that adhere to industry standards such as IEEE C37 for high-voltage equipment. The substation's location in Indiana places it within the footprint of the Midcontinent Independent System Operator (MISO), which manages the regional transmission grid. Hoosier Energy's network of substations supports the delivery of power to member cooperatives and their end-use customers, contributing to the stability and resilience of the local electrical infrastructure. The facility's operational status ensures continued service to the community.

The substation is situated in a rural area of Indiana, characterized by agricultural land and scattered residential developments. The 69 kV voltage level indicates a sub-transmission role, connecting local distribution networks to higher-voltage transmission lines. The facility's design and operation must consider environmental factors such as stormwater management, electromagnetic field (EMF) mitigation, and wildlife protection, particularly for birds and other species that may interact with power lines. Compliance with local environmental regulations and NERC standards helps minimize ecological impact.
