A method of power distribution in an electronic control system (9) at an electrically powered mining or construction machine (2). A line converter (5) is selectively connectable to a mains power source (4) and an on-board battery (6) and/or fuel cell. All power sources (4, 6) are connected to a DC bus (7) to supply consumers (8). Predefined energy supply modes (ESM) are provided, defining how energy is to be distributed by predefined control sequences defining start-up sequences for initiating, shutdown sequences for terminating, and handover sequences for changing from a first to a second energy supply mode. In response to operator selection of activation of a specific energy supply mode is executed the predefined control sequence for start-up of, or if already operating in another mode handover to, the operator selected specific energy supply mode, or in response to operator selection of de-activation of a specific energy supply mode, the predefined shutdown sequences for terminating the operator selected specific energy supply mode.
