ETAP version 22 (officially released in late 2022) is an electrical digital twin solution designed to enhance the safety, reliability, and sustainability of power systems
. It introduced significant updates for renewable energy integration and international compliance standards. Key Features and Updates
ETAP Version 22 introduced several significant features focused on digital twins, renewable energy, and advanced safety compliance.
Below are drafts of three standout features you can use for reports, presentations, or training: 1. GridCode™ Smart Inverter Modeling
This feature addresses the shift toward decentralized energy by allowing engineers to model how smart inverters interact with the grid autonomously.
Key Capability: Simulates autonomous decision-making for grid stability based on Volt-Var, Volt-Watt, and Watt-Power Factor control modes. etap version 22
Engineering Benefit: Ensures compliance with modern standards like IEEE 1547-2018 and California Rule 21 during the design phase of renewable projects. 2. ArcSafety™ & eLabel™ Maker
Version 22 significantly upgraded safety tools to bridge the gap between analysis and field implementation.
Key Capability: A dedicated graphical tool for creating Arc Flash Label templates that include QR codes for instant access to digital twin data in the field.
Engineering Benefit: Simplifies the generation of compliant labels under international standards like DGUV (German) and IEC 60909. 3. Star™ Protection & Selectivity Enhancements
The protection module received deep visual and analytical upgrades to improve system reliability. ETAP version 22 (officially released in late 2022)
Key Capability: Introduces Auto-Evaluation of cables based on let-through energy and allows visual verification of cable size selection against MCCB current-limiting curves.
Engineering Benefit: Reduces the manual effort needed to verify that protective devices properly coordinate with and protect cable withstand capabilities. Summary of Other Notable Additions:
Lightning Risk Assessment: Tools to assess and identify risks for structures according to NFPA 780.
etapPy™ Expansion: Enhanced Python scripting capabilities for automating complex studies like Unbalanced Short Circuit and Switching Optimization.
Expanded Equipment Libraries: Over 8,500 new protective device models and 4,000+ solar panel models. What's New - ETAP IEC 60909 Updates: Algorithms have been updated to
ETAP 22 is a major release of the Electrical Transient Analyzer Program, introduced in late 2022. It focuses on "Sustainability through Continuous Intelligence," providing a unified Electrical Digital Twin solution for the design, operation, and automation of power systems. Core Capabilities

The core studies are now faster thanks to multi-core processing. Version 22 can handle networks with over 100,000 buses without performance degradation. New reporting features include "what-if" scenario comparison tables, allowing engineers to compare base case, contingency, and future load growth side-by-side.
While arc flash analysis existed in prior versions, version 22 fully integrates the latest IEEE 1584-2018 equations with a new 3D electrode configuration tool. Engineers can now model:
