Arizona Corporation Commissioner Lea Márquez Peterson has been elected Chair of the Western Interconnection Regional Advisory Body (WIRAB), assuming a critical role in guiding electric grid reliability efforts across the expansive Western region of North America. In an election that canvassed energy policy experts from three countries, Commissioner Márquez Peterson emerged as a figure of experience and determination, ready to confront the challenges inherent in an evolving energy sector, according to the Arizona Corporation Commission.
Bringing a rich tapestry of regulatory insight, Commissioner Márquez Peterson steps into her role as Chair with significant credentials, having represented Arizona on WIRAB since June 2021 and played the role of Vice Chair since May 2023. Tasked by the organization, her leadership is set to confront the complexities involved in areas like long-term transmission planning and grid modernization, as reported by the Arizona Corporation Commission.
"It's an honor to serve as Chair of WIRAB and represent Arizona in the Western region," Commissioner Márquez Peterson said according to an official statement. "As we navigate historic changes in energy, I look forward to working with my colleagues across the West to ensure a reliable and resilient grid that serves all of our communities," as stated by the Arizona Corporation Commission.
The Western Interconnection grid, providing power to nearly 90 million people across North America, is a patchwork of states, provinces, and one Mexican state. WIRAB's guidance in this region — charged with advising FERC, NERC, and WECC — is an integral part of the planning and coordination process, ensuring the grid not only meets current demands but is also fortified against emerging risks. As the Chair, Commissioner Márquez Peterson's vision would reign over a landscape where climate concerns and sustainable practices dominate the conversation on energy policy, as per the Arizona Corporation Commission.
