Record-breaking heat indices reaching 115 degrees have prompted emergency load-shedding protocols in several Southern states. Utility operators are urging residential customers to limit air conditioning use during peak hours between 3:00 PM and 8:00 PM to prevent rolling blackouts.

As the heatwave persists, state governments are reviewing long-term investments in battery storage and renewable energy integration.
