Duke Energy Florida Achieves Record Low Outage Duration for Customers in 2025

Duke Energy Florida has recently made headlines by marking a significant milestone in reliability, achieving the lowest average outage duration for customers in over twenty years. In 2025, the average outage time was recorded at just 64 minutes per customer. This achievement is particularly commendable as it excludes lengthy outages caused by major events like hurricanes. This remarkable performance is primarily credited to comprehensive grid hardening efforts across the state.

Understanding Grid Hardening

Grid hardening refers to the strategic investments made in electrical infrastructure aimed at enhancing reliability even during adverse weather conditions. This approach allows Duke Energy Florida to provide uninterrupted service, regardless of the weather, whether it's a light drizzle or a hurricane.

Duke Energy Florida has deployed a multisector team comprising engineers, arborists, and construction workers, who work tirelessly throughout the year. Their collaborative efforts focus on several projects that enhance the resilience of the energy grid.

Key Strategies for Improvement

The company has adopted various strategies to ensure durability and reliability, including:

1. Pole Upgrades

Significant investment has been made in upgrading wooden power poles to more robust materials like concrete and steel. Over the last five years, approximately 60% of the company’s transmission poles have been enhanced, with a goal of completing these upgrades by 2028.

2. Undergrounding Power Lines

To prevent recurring outages caused by fallen branches or difficult-to-access hardware, overhead power lines are being buried underground. This proactive measure enhances protection against natural elements and streamlines maintenance during outages. Currently, about 50% of the distribution system is underground.

3. Smart Technology Implementation

Duke Energy Florida employs smart, self-healing technology that functions similarly to GPS. This innovative system automatically detects outages, rerouting power to other lines, and facilitating faster restoration of service—often within a minute or even preventing outages altogether. It has been reported that approximately 82% of Duke Energy Florida’s customer base, exceeding two million customers, benefits from this technology. In 2025, it avoided roughly 280,000 potential extended outages and saved millions of outage hours during the tumultuous 2024 hurricane season.

The impact was significant during Hurricane Milton, where an impressive saving of 3.3 million outage hours was recorded, alongside 1.8 million hours during Hurricane Helene and 208,000 during Hurricane Debby.

Perspectives from Leadership

Melissa Seixas, the state president of Duke Energy Florida, expressed gratitude for the favorable weather conditions in 2025 but noted the unpredictability of Florida's climate. “Living in Florida, we know it’s not a matter of ‘if’ but ‘when’ the next storm will strike. Our ongoing efforts are tailored to boost reliability and ensure that our customers remain connected when they need it the most,” Seixas stated.
