MAIN POWER SYSTEMS BOARD

 The illustration shows the Main Power Systems Board, monitored by the Engineering Watch Officer at all times. This displays all Power Sources, Fuel Storage Facilities, Power Distribution Systems, Power Grids, and Propulsion Systems. There are three Power Sources aboard a starship, and five Major Distribution Networks to carry said power to the usage points or Power Grids. When not running on the Mains, it is the duty of the Power Division to balance the demand for power within one or more of the Power Grids so as to match the power output available. This may entail the temporary shut-down of various non-essential Systems within a Grid. Contrawise, a particular System (such as Sickbay) may order that it be given priority treatment. The Power Sources, Distribution Networks, Power Grids, and Systems are listed below according to capacity and power demands.
