An elevator energy management system (20) includes a first variable frequency drive (32) configured to deliver electrical power from a power source to an elevator machine (30) during a first operating condition and to receive regenerative energy from the elevator machine (30) during a second operating condition. A second variable frequency drive (34) is configured to selectively receive regenerative energy from the first variable frequency drive (32) during the second operating condition. At least one energy receiving device (36) is coupled with the second variable frequency drive (34). The energy receiving device (36) is configured to receive regenerative energy from the second variable frequency drive (34).
