  This article presents a use-inspired perspective of the opportunities and
challenges in a massively digitized power grid. It argues that the intricate
interplay of data availability, computing capability, and artificial
intelligence (AI) algorithm development are the three key factors driving the
adoption of digitized solutions in the power grid. The impact of these three
factors on critical functions of power system operation and planning practices
are reviewed and illustrated with industrial practice case studies. Open
challenges and research opportunities for data, computing, and AI algorithms
are articulated within the context of the power industry's tremendous
decarbonization efforts.
