⚡ Bi-Directional Regenerative VFDs, Energy Recovery (30-40% Returned to Grid)

Elevator Regenerative Drive Energy Calculator

Model energy capture from regenerative variable frequency drives (VFD) on gearless traction elevators: calculate clean AC power regenerated back onto the building grid when a heavy counterweight descends or a fully-loaded cab descends (cutting elevator net electricity consumption by 30-40% and eliminating hoistway heat dissipation), and energy ROI.

1. Project & Operating Inputs

Elevators Equipped with Regen Drives (Cab Count e.g. 8 High-Rise Cabs)
