⚡ 4-Quadrant AFE Regen (30% to 50% Elevator Energy Recovery & Utility Rebates)

Elevator Regenerative Drive Calculator

Calculate electrical energy generation and utility peak demand savings from 4-quadrant Active Front End (AFE) regenerative elevator drives (Otis ReGen / KONE EcoDisc): calculate kWh returned to building grid during overhaul trips (full cab descending or empty cab ascending against the counterweight), calculate annual dollar savings, and energy efficiency ROI.
