Pace and complexity of the energy transition in power grids is creating challenges for grid operators, market participants, and consumers. Absent intervention, grids will need substantial investment in physical and operational infrastructure to accommodate new resources and maintain stability. Artificial intelligence (AI) may offer pathways to ease or even accelerate this transition. What are natural applications for AI in transmission and distribution grids? Where are the present opportunities and how might these be scaled? What key barriers must be addressed?
