Power Factor Correction Analysis for Moroccan Industrial Facilities: Technical and Economic Evaluation
Chaimaa Labyad
Abstract. Despite Morocco’s ambitious National Energy Efficiency Strategy and growing industrial electrification, poor power factor remains a major contributor to system inefficiency and high electricity bills and in Moroccan industrial facilities, where small induction motors (0.5–2 hp) incur up to 20% reactive power surcharges under ONEE tariff structures, while simultaneously increasing transmission losses and placing unnecessary strain on the national grid infrastructure[1,6]. This study develops and validates an optimized shunt capacitive power factor correction system for a representative single-phase R-L load (R = 10 Ω, L = 50 mH, 1.526 kW) connected to Morocco’s standard 230 V, 50 Hz low-voltage grid. Comprehensive phasor-domain circuit analysis in Simulink MATLAB, supported by resonance analysis and detailed phasor diagrams, identifies 140 µF as the global optimum. This single capacitor raises power factor from 0.537 to 0.999 (86 %improvement), reduces line current by 46.2% (from 12.35A to 6.64 A), and cuts reactive power by 97.1 % (from 2396 VAR to 70 VAR). Economic analysis using 2024-2025 ONEE tariffs shows 33-month payback with 1,933 MAD/year savings and 10-year NPV of 9,467 MAD. Therefore, this study demonstrates a technically feasible and economically attractive energy efficient intervention for Moroccan industrial facilities, that aligns fully with national energy policy objectives [1,9].
