Do you trust your local utility provider to restore power promptly after severe storms?
The Indiana Utility Regulatory Commission has initiated a formal investigation into NIPSCO following massive power outages caused by storms on August 11, 2026. Nearly 300,000 customers lost electricity during the severe weather event.
Why it matters
The investigation seeks to evaluate NIPSCO’s infrastructure maintenance and restoration protocols after concerns were raised regarding the length of time customers remained without power. The inquiry was requested by the Indiana Office of Utility Consumer Counselor.
Since 2016, NIPSCO has been authorized for $2 billion in infrastructure improvements and spent over $200 million on vegetation management. These investments are being reviewed against past performance, including 2025 outage data.

Market Landscape
The probe examines if the utility’s capital expenditure strategy aligns with its mandated public service requirements. This investigation reflects a growing regulatory push to hold energy providers accountable for infrastructure performance during peak storm events.
Customers who experienced prolonged outages may see changes to service restoration protocols or infrastructure priorities. This investigation could lead to new requirements for how the utility manages vegetation and equipment maintenance in the future.
The takeaway
