Electrisim's results have been independently validated against Neplan (commercial software) in two master's thesis from the University of Palermo, confirming accuracy across load flow, short circuit, and other analyses.
Read the full validation study →Offshore wind load flow is checked by running the same model through pandapower and OpenDSS: about 70 buses, 35 branches, and 450 MW of wind—demonstrating consistent results across two major solvers.
Read the dual-solver validation article →Electrisim's pandapower engine passes 250+ automated tests. Power flow and short-circuit results for every element are validated against DIgSILENT PowerFactory and PSS Sincal, with strict tolerances on voltage (0.000001 p.u.), angles (0.01°), and loading (0.001%)—continuous integration on every change.

Electrisim is built on two of the most widely adopted open-source power system simulators. Estimated community reach:
Get started in three simple steps
Drag and drop electrical components onto the canvas to build your power system model. Buses, lines, transformers, generators, loads, and more.
Set voltage levels, power ratings, impedances, and other parameters for each component through intuitive dialog forms.
Run load flow, short circuit, protection coordination, optimal power flow, reactive power capability (PQ), or other analyses and view results instantly on the diagram and in tables.
Watch how easy it is to model complex electrical networks with our intuitive drag-and-drop interface
Model an electrical system, perform simulation and analyse results in a secure cloud software. You can also run the software locally — check the open-source code. Currently, the power flow, short circuit analysis, protection coordination study (beta), optimal power flow, contingency analysis, controller simulation, time series simulation, economic analysis, and reactive power capability (PQ diagram) are available. More to come soon.
Works in your browser or as a desktop application – you choose which is better for you.
Completely free to use when deployed locally. Built by passionate power engineers and developers, Electrisim democratizes access to professional-grade power system analysis tools for everyone. Learn more about our mission.
The calculation algorithms are based on Pandapower and OpenDSS, which proved to give the same results as other renowned power system analysis software. The Electrisim software is tested by numerous scenarios to verify the proper results.
The Electrisim cloud runs on Railway, a platform built for production workloads. Railway is SOC 2 Type II and SOC 3 certified, publishes security and compliance details in its Trust Center, and protects traffic with TLS. GDPR-focused processing agreements and stronger enterprise controls are available for teams that need them.
User-friendly graphical user interface (owing to Diagrams.net), based on drag-and-drop functionality for creating electrical diagrams.
Use instantly in your browser with our cloud software, or deploy locally on your computer for complete data privacy and offline capabilities.
Your subscription (from $10/month) directly funds ongoing development and new features. Subscribers help define the roadmap—tell us what you need and we prioritize it. Join a growing community of engineers shaping the future of open-source power system analysis tools.
Design networks on a geographic map: place buses, generators, transformers and loads at real locations, draw cables between them, and generate an electrical model with automatic cable length calculation. Ideal for offshore wind, distribution and transmission planning.
Real workflows: solver settings, harmonics, built-in templates, large-scale renewable models, post–load-flow Network Health Dashboard, multi-page Engineering Report PDF (cover, diagram, tables), and more—the same interface you get when you subscribe.
Reactive power capability (PQ diagram) — compare plant Q capability at the PCC against grid-code requirements; compliance status, voltages, and CSV export.
1 GW offshore wind — full single-line view from turbines to the external grid.
Ready-made templates — start from onshore wind, offshore, or solar examples.
Harmonic analysis — spectrum and total harmonic distortion (VTHD) across buses.
Load flow — choose Pandapower or OpenDSS, iterations, tolerances, and exports.
Add Reactive Power Characteristic to your generators
Result export — export the simulation results.
Code export — generate Pandapower or OpenDSS code based on the Electrisim schematic.
Map editor — convert automatically your model from map to electrical model.
Powered by pandapower and OpenDSS — choose the engine per study. Full details in the documentation →
Build any network with a comprehensive component library — available in Pandapower and OpenDSS frameworks.
…plus motors, external grids, shunts, impedances, 3-winding transformers, DC lines, switches, BESS, FACTS (SVC, TCSC, SSC), and more. See the full component library →
