Elevator Energy Regeneration System

Turn Wasted Lift Energy Into Building Power

Capture and reuse braking energy with 20%–50% proven savings. A non-invasive, parallel-connected retrofit that requires just 15–30 minutes of downtime per lift.

A lift motor acts as a generator whenever the car moves against the counterweight — travelling down with a heavy load, or up with a light one. In most existing lifts, this energy is routed to a brake resistor and released as heat inside the machine room.

EERS captures that energy, filters it, and feeds it back into the building's power supply, where it is consumed immediately by lighting, fans and other common-area loads.

Because the energy is no longer dissipated as heat, machine-room temperatures fall. In a tropical climate this matters: machine-room heat accelerates component ageing across a lift's 20–30 year service life, and lower temperatures reduce that thermal stress.

01

Parallel Connection

The device is connected in parallel with the existing brake-resistor circuit. It does not modify the lift's original control logic or safety circuits.

02

Automatic Fallback

If the device develops any fault, the lift reverts automatically to its original brake-resistor mode and continues to operate normally.

03

Brand Compatibility

Validated on lift brands commonly found in Asia, including Hitachi, Fujitec, KONE, Mitsubishi, Otis, Schindler, Yungtay and Canny.

04

No Added Maintenance

The device requires no scheduled servicing and adds nothing to the lift's existing maintenance routine.

05

Quick Installation

15–30 minutes per lift, with no extended downtime for residents or tenants. Electrical connection is carried out by a Licensed Electrical Worker in Singapore.

For clients who want to verify performance, we offer an optional 4G smart meter package that records regenerated energy independently of the lift's own systems. Under the shared savings model it is included as standard, since metered data forms the basis for settlement.

Building owners and managers can view real-time and historical data through an online dashboard, and receive regular savings reports suitable for management updates. An English interface is provided on deployment.

Energy regeneration for lifts is offered in several forms. These are the points worth checking, whichever supplier you speak to.

What to checkOur systemWhat to watch for elsewhere
Safety & approvalsParallel connection; no modification to control or safety circuitsSolutions that modify lift circuits can trigger additional inspection and approval requirements
Energy storageCapacitor-based, no batteriesBattery-based systems carry ageing and thermal-runaway risk in hot machine rooms
Power qualityIndustrial DSP and PWM control, THD below 5%Higher harmonic distortion can interfere with lift control electronics
Heat outputLow internal loss, minimal effect on machine-room temperatureDevices with high internal loss add to the machine room's heat load
MaintenanceNo scheduled servicing; existing lift maintenance routine unchangedSome systems add servicing requirements and coordination
VerificationIndependent metering; savings traceableWithout separate metering, savings are difficult to substantiate
ScalingSupports multi-lift and parallel deploymentFixed configurations limit estate-wide rollout

Built to international industrial standards, ensuring long-term reliability and peace of mind for building management.

  • Battery-Free Energy Storage: Capacitor-based design eliminates the fire and thermal-runaway risks associated with chemical batteries.
  • Comprehensive Protection: Equipped with multiple safeguards including overcurrent, short-circuit, and overheating protection.
  • Strict Compliance: Engineered for low harmonic distortion (THD < 5%) to prevent any interference with lift control electronics.

A seamless, end-to-end partnership designed for property teams—from initial feasibility to ongoing peace of mind.

  1. Consultation & Assessment We review your lift profiles, assess baseline energy usage, confirm brand compatibility, and deliver a clear, data-driven savings forecast.
  2. Efficient Installation Wiring and preparation are conducted beforehand with zero lift downtime. Actual lift interruption is limited to a rapid 15–30 minute power-down window per lift, executed by certified professionals.
  3. Testing & Handover Rigorous functional testing, optional smart meter configuration, and a complete handover with all documentation provided.
  4. Ongoing Operation Smooth integration into your building. For clients with the optional smart meter package, real-time monitoring and periodic savings reports are included.
