The century-old electric grid is evolving into a modern and sophisticated machine to unlock a greener economy and fight off global warming. Coordinating the alignment of environmental and energy goals is critical to developing a cleaner, reliable and more weather-resilient power grid. The ISO is collaborating with state and federal agencies, policymakers, stakeholders and end-user groups during this historic transformation to meet the challenges and opportunities ahead.
