Hoosier Energy’s grid infrastructure ensures that we reliably and efficiently serve our 18 member systems.

A reliable and resilient grid is at the core of our operations. As technologies continue to advance, Hoosier Energy is taking proactive steps to ensure the transmission system is stable and modernized to meet the growing demands of the member systems and the communities they serve. This involves deploying emerging tools and technologies to accommodate resource diversity, shifting customer demand and the need for resilience.

Preparing the Grid for the Future

The energy ecosystem is rapidly transitioning to a digitized, decentralized and demand-focused space with more resource variability and diversity requiring the grid to meet these shifts in a substantially different way than in year’s past. The grid is smarter, modern and more technologically advanced.

Hoosier Energy continues working to enhance the grid to enable 24/7 reliability with a strong focus on resilience. One example of modern advancements we makes use of is the robotic line technology we use to monitor the health of the system. This process allows us to proactively identify potential issues and respond in a more measured and efficient manner without taking lines out of service. The use of this new technology to improve visibility and reliability across the system is  just one way we are targeting capital investments to enhance our capabilities as we power forward into the future.

Improving System Reliability

Hoosier Energy is a member of both the Midcontinent Independent System Operator (MISO), a regional transmission organization (RTO) that reaches over 42 million people across 15 states and the Canadian province of Manitoba, as well as the PJM Interconnection. MISO and PJM are focused on three critical tasks:

  • Managing the generation and transmission of high-voltage electricity (the bulk electric system)
  • Managing the wholesale energy markets across the region
  • Planning the grid of tomorrow

Being a part of a larger energy ecosystem through the RTOs enables Hoosier Energy to achieve greater scale, which translates into savings, improved efficiencies, and connection to a geographically diverse resource pool and a dependable and reliable transmission system.

Grid Transmission Projects

Centerton to Wilbur

The Hoosier Energy Wilbur to DEI (Duke Energy Indiana) Centerton 69kV reliability project includes constructing 5.8 miles of new 69kV overhead transmission line. The line will connect the Hoosier Energy Wilbur substation to the Duke Energy Centerton substation, both in Morgan County. The project is critical to improve the reliability of the transmission grid – the backbone of the electric system – by adding another power source to feed the area.

Hoosier Energy Service Interruptions

DISCLAIMER: The service interruptions listed on this page are for reference purposes only and are not representative of the real-time status of Hoosier Energy’s electrical system. Affected consumer counts and restore times are based on normal system configuration. Conditions of each Member Cooperative’s distribution system or switching actions by Hoosier Energy and Member Cooperatives may result in individual outage durations which are different than what is posted here. Always refer to your Member Cooperative’s outage map for the most up to date information about individual services. Interruptions are posted to this page as soon as possible, typically within 30 minutes of each occurrence, and records will be kept on this page for 90 calendar days.
