It is a critical utility that plays an indispensable role in modern life, supporting virtually every aspect of society and industry.

Ensuring a reliable and safe electric service is essential for public safety, economic productivity, and quality of life, and it is underpinned by rigorous regulatory standards and infrastructure maintenance. The ongoing evolution of the electric service sector includes advancements in renewable energy integration, smart grid technology, and energy efficiency measures, all contributing to a more sustainable and resilient energy future.
