A utility digital twin depends on accurate and governed models: GIS, ADMS, EMS, OMS, planning, asset, protection, DER, and customer connectivity data must be aligned enough for the selected use cases.
Model governance is not only a technical task. It requires source-of-truth ownership, model versioning, topology validation, change control, comparison workflows, approval, promotion, rollback, and continuous validation.
TwinGrid treats model readiness as an early decision gate, not a late implementation issue.
