Abstract: A method and an elevator for moving an elevator car to a landing floor in case of a predefined event related to a main electrical power supply of an elevator are disclosed. The method includes charging energy from the main electrical power supply into an external electrical energy storage prior to detecting the predefined event related to the main electrical power supply, controlling an operation of an electric motor for moving the elevator car with an electrical drive to decelerate the elevator car and to produce regenerative electrical energy, selectively utilizing said energy charged from the main electrical power supply into the external electrical energy storage and said produced regenerative electrical energy to maintain an elevator brake in deactivated state.
