Abstract: | This report reviews the elements of smart transmission and the investments that transmission providers are making to modernize and improve North America’s high voltage grid. Although today’s high voltage transmission system already contains high levels of sophisticated monitoring, analysis, automation, two-way communications, and power electronics, new investments are increasing the grid’s digital management capabilities and efficiency as well as its throughput and reliability. This report focuses on transmission-level technologies and the new investments being made to enhance the transmission system with these technologies.
