The escalating demands of artificial intelligence, cryptocurrency mining, and electric vehicle adoption have exposed critical vulnerabilities in the North American power grid infrastructure. This paper proposes Project DAWN (Digitalization, Adaptability, Wellness, and Network optimization), a comprehensive framework for modernizing the tri-national power grid serving the United States, Canada, and Mexico. Through systematic literature review and comparative technology assessment, this study identifies optimal solutions for three critical smart grid components: cybersecurity architecture, big data management systems, and energy storage infrastructure. The proposed system integrates Dynamic Line Rating (DLR) technology, Phasor Measurement Units (PMUs), Advanced Distribution Management Systems (ADMS), Fault Location Isolation and Service Restoration (FLISR), Advanced Metering Infrastructure (AMI) with blockchain integration, and Distributed Energy Resource Management Systems (DERMS). Financial analysis projects implementation costs between $127-150 billion over a 15-year timeline, with estimated returns exceeding costs by factors of 2.8 to 4.0 through enhanced efficiency, reduced outage costs, and renewable energy integration. The phased implementation strategy encompasses pre-implementation (feasibility and stakeholder engagement), implementation (infrastructure upgrade and technology deployment), and post-implementation (evaluation and continuous improvement) phases. Decision criteria emphasize security, efficiency, reliability, and sustainability. This research contributes practical insights for policymakers, utility operators, and technology vendors navigating the transition to intelligent, resilient, and sustainable power infrastructure capable of supporting 21st-century energy demands while accelerating decarbonization objectives.
