Utilities have invested heavily in operational technology to monitor and control the grid in real time. But as DER adoption, electrification, and extreme weather reshape how the grid behaves, knowing what’s happening right now is no longer enough. Utilities need to understand why it’s happening, what comes next, and how a decision made today will play out years from now.

This white paper explores how a utility digital twin complements existing OT systems by bringing together past, present, and future views of the grid in one place. It explains the difference between systems built to watch and act and a platform built to visualize, simulate, and forecast, and shows how opening that insight to authorized users across the utility can improve planning, operations, and decision-making.

Written from EnerNex’s experience helping utilities plan and implement grid modernization programs, this paper is designed to help you assess where a digital twin fits in your organization and how to get started.
