NEPLAN Electricity is the core module for electrical network analysis, planning, optimization, and simulation. It handles transmission, distribution, generation and industrial networks-enabling organizations to design, evaluate, and optimize their electrical infrastructure.
Support for both steady-state and dynamic modelling, including 1-, 2-, and 3-phase AC (with neutral & earth) and DC systems.
Efficient algorithms manage 500,000+ busbars for enterprise-scale studies.
Designed to international standards (IEC/ANSI/IEEE) with customizable libraries for components, protection, and control circuits across regional markets.
Run as a desktop client, multi-user intranet, or in the cloud-choose what best fits your IT strategy.
Ideal for networks integrating renewables, distributed generation, e-mobility, and smart-grid tech-assess PV/EV host capacity, ensure grid-code compliance, and evaluate protection devices as architectures evolve.
Key Modules & Features
What each module does, where it’s used, and why it matters for modern power systems.
Fundamental tool for modelling how power flows under normal or contingency conditions. Supports AC & DC, radial & meshed networks, and 1/2/3-phase systems. Helps plan network capacity, identify overloads, and ensure stable operation.
Calculates fault currents (single, double, two-, three-phase; with/without earth) in AC/DC systems. Supports protection design, safety, and fault ride-through planning.
RMS stability, modal/eigenvalue analysis, and EMT for fast transients. Assess system behaviour during disturbances and interactions of renewables/power electronics.
Harmonic Analysis, Voltage Sags/Swells, Flicker, Voltage Quality, etc. Examine non-ideal behaviour to design filters, reduce distortion, and verify compliance with regulatory limits.
Overcurrent protection/selectivity, distance protection, fault finding, etc. Set & assess protection devices, coordinate curves, and ensure selectivity & system response under faults.
Evaluate how much DER/EV charging a network can host without violating voltage/thermal/stability limits. Pinpoint feasible connection points-even when “capacity” isn’t stated explicitly.
Reliability and cost analysis, investment planning, life-cycle assessments. Modules like Reliability Analysis, Investment Analysis, cable/overhead line thermal capacity, optimal capacitor placement, etc., help prioritize investment and maintain network health.
Cable sizing, overhead line parameter calculations, arc-flash, network reduction, net transfer capability, restoration strategies, and more-supporting safer, more precise system operation.
