PSO is making a significant investment to strengthen the electric grid and deliver more reliable service for customers across its service area.

Se está llevando a cabo un esfuerzo en todo el sistema para actualizar más de 100 circuitos de distribución a líneas de mayor voltaje, un paso importante que mejora el rendimiento, reduce los apagones y permite la incorporación de nueva tecnología en la red. Para los clientes, esto significa menos apagones, interrupciones más cortas cuando ocurren y mejor calidad de la energía eléctrica para hogares y negocios.

This multi-year initiative reflects PSO's continued focus on proactive improvements that benefit customers every day. The work includes installing new poles, crossarms, wire, and other modern equipment designed to serve communities for decades to come. As of May 2026, crews have upgraded 595 transformers, replaced 1,934 poles, and installed more than 450,000 feet of wire.

Some of the lines being upgraded date back decades, making this one of the most impactful modernization efforts on the system. By upgrading these circuits, crews are preparing the grid to be updated with new technology.

This progress is being made across the state in areas like Tulsa, Lawton, and Okmulgee. With 37 crews dedicated to the work, progress is steady and highly visible in the communities PSO serves.

“When you see this work in the field, it resembles a major storm response—with multiple crews working simultaneously to upgrade equipment and strengthen the system,” said Tyler Devereux, Managing Director of Distribution Operations.

By proactively upgrading infrastructure, PSO is helping ensure customers experience fewer disruptions, more consistent service, and a grid that is ready to meet both today’s needs and future demand.

This large-scale effort is expected to continue through 2030, representing thousands of hours of work and a major step forward in building a stronger, more resilient grid for Oklahoma.
