Electrical Transient Analyzer Program
Electrical Transient Analyzer Program (ETAP) is a comprehensive, industry-leading software platform used for the design, modeling and simulation, analysis, and operation of electrical power systems. It is developed and licensed by ETAP, which is part of Schneider Electric. The core function of ETAP is to create a digital twin of an electrical network, allowing engineers and operators to model, simulate, and optimize the system's performance, power system dynamics, transient and protection, reliability and safety across its entire lifecycle. The software provides a unified, intelligent electrical network model from original concept and design through to operations and maintenance. ETAP’s capabilities are organized into a modular suite of tools covering a wide range of power system studies. Key analysis modules include load flow and voltage Drop, short Circuit analysis (per ANSI, IEC, and other standards), and protective device coordination to ensure system protection. More advanced features encompass transient Stability, harmonics analysis, arc flash hazard calculation, and Optimal Power Flow. This broad functionality makes ETAP a versatile tool utilized across numerous sectors, including power generation, transmission, distribution, as well as industrial, commercial, and transportation power systems. Schneider Electric took controlling stake in ETAP on November 16, 2020. The current CEO of ETAP is Tanuj Khandelwal who previously held the role of CTO and has been employed at ETAP for over 20 years. ETAP was developed for utilization on MS-DOS operating system and intended for commercial and nuclear power system analysis and system operations.

Ownership and Corporate Structure
[edit]ETAP (Operation Technology, Inc.) was founded in 1986 by Farrokh Shokooh and operated as a private, independent software company based in Irvine, California, for decades. This independent status allowed ETAP to develop its flagship software as a vendor-agnostic platform, meaning its modeling and analysis tools are designed to work with equipment from virtually any manufacturer.[6] The company grew to become a global leader in power system design, modeling, and simulation, servicing utilities, industrial facilities, and major engineering firms worldwide before a significant change in its corporate ownership structure.
The company’s ownership fundamentally shifted in 2021 when Schneider Electric completed the acquisition of a controlling stake in ETAP.[7] The initial agreement for Schneider Electric to acquire 80% of the company was signed in November 2020, with the transaction completing in June 2021. Despite being consolidated within Schneider Electric's Energy Management business, ETAP continues to operate as an independent software vendor. This arrangement is designed to allow ETAP to maintain its vendor-agnostic status, while its technology is integrated into Schneider Electric's broader digital offerings, enhancing their combined capabilities in electrical design and digital twin solutions for mission-critical power systems.[8]
