An elevator energy management system includes a first variable frequency drive configured to deliver electrical power from a power source to an elevator machine during a first operating condition and to receive regenerative energy from the elevator machine during a second operating condition. A second variable frequency drive is configured to selectively receive regenerative energy from the first variable frequency drive during the second operating condition. At least one energy receiving device is coupled with the second variable frequency drive. The energy receiving device is configured to receive regenerative energy from the second variable frequency drive.
