This document discusses e-terra's network management solutions for electrical grids. It summarizes e-terra's mission to provide solutions to manage transmission and distribution grids through products like their EMS, DMS, and distribution planning tools. These tools use model-based analysis, optimization algorithms, and wide-area situational awareness through PMU data to help control voltages, flows, and reliability across high voltage transmission and distribution systems. The document also outlines e-terra's user community support and focus on cyber security.
