Duke $DUK Energy DUK is modernizing its long-standing power network by integrating advanced technologies to create a more reliable, efficient, and resilient grid system.
The company currently anticipates spending capital worth $200-$220 billion over the next decade. Of this, it currently expects to spend nearly $103 billion during 2026-2030. This investment is focused on transforming its 320,000 miles of power lines — the largest transmission and distribution system in the United States, upgrading existing infrastructure and building new power generation to support growth, and investing in its natural gas local distribution companies.
Duke Energy is using grid modernization as a core growth driver, developing scalable and repeatable infrastructure solutions to support rising demand from AI and economic expansion. Further modernization of the electric grid, including smart meters, storm hardening, self-healing and targeted undergrounding, also helps ensure the system is better prepared for severe weather conditions.
In 2025, advanced self-healing technology prevented nearly 2.2 million customer outages across Duke Energy’s six-state service area, saving approximately 5.2 million hours of total outage time. About one-third of these gains occurred during major storms, underscoring its value as a critical tool for field crews restoring power after severe weather. As of Dec. 31, 2025, nearly 75% of the company’s electric customers were supported by self-healing technology on primary distribution lines — more than double the level achieved three years earlier.
