Electrisim vs NEPLAN-class commercial tools

NEPLAN-class tools are common in European consulting and DSO workflows. Electrisim targets the same IEC-oriented studies with open-source engines and a published Neplan validation study.

Feature Electrisim Typical NEPLAN-class licensing
Monthly cost $10 per month Personal
$40 per user per month Company
Often $500+ per month or large perpetual licenses
Load flow / power flow pandapower + OpenDSS
Short circuit (IEC 60909)
Arc flash (IEEE 1584-2018)
Motor starting / voltage dip
Optimal power flow
Harmonic analysis
Transient stability & eigenvalues ANDES
Cloud access (no install) Often desktop / VPN locked
Open source Apache 2.0
Cancel anytime Multi-year contracts common

Core studies aligned with NEPLAN workflows

Choose the engine per study — pandapower, OpenDSS, or ANDES. Full documentation →

Validated against commercial software

Results are driven by mature open engines and checked against commercial tools and independent academic work.

Commercial-tool validation

pandapower power flow and short-circuit results are validated against DIgSILENT PowerFactory and PSS Sincal with strict tolerances — continuous CI on every change.

pandapower validation →

Independent thesis study

Master’s thesis work at the University of Palermo compared Electrisim with Neplan across load flow and short circuit.

Dual-solver checks

Offshore wind load flow is cross-checked through pandapower and OpenDSS on the same model — consistent results across two major solvers.

When Electrisim is the right NEPLAN alternative

Best fit for

  • Consultants and plant engineers who need core network studies daily
  • Teams priced out of enterprise seats or waiting on license renewals
  • Students and researchers who want inspectable, open engines
  • Air-gapped sites that can self-host the Community Edition

Still use NEPLAN when you need

  • Specialized modules Electrisim does not yet cover 1:1
  • Client or utility mandates that require a named commercial suite
  • Legacy models and workflows already locked into NEPLAN

Many engineers run Electrisim for day-to-day studies and keep a commercial seat only where contracts require it.

NEPLAN alternative FAQ

  • For many day-to-day studies — load flow, short circuit, arc flash, OPF, harmonics, motor starting, and dynamics — yes. Electrisim uses pandapower, OpenDSS, and ANDES. It is not a 1:1 replacement for every specialized NEPLAN module, but it covers core network analysis at a much lower price.
  • Cloud Personal is $10 per month, Company $40 per user per month, cancel anytime. A free open-source Community Edition is also available. NEPLAN is usually sold as an enterprise license. See pricing.
  • Yes. Deploy the Community Edition from GitHub locally, or use the browser cloud app with zero install.
  • Yes. Electrisim runs arc flash to IEEE 1584-2018 (incident energy, AFB, PPE) on top of IEC 60909 short-circuit results. See the arc flash documentation.
  • Typical replacements: load flow, short circuit, arc flash, motor starting, OPF, harmonics, contingency analysis, protection coordination (beta), transient stability / eigenvalues (ANDES), and PQ capability studies. Check the roadmap for what is coming next.
