A downhole power management technique for a downhole well control system maximizes the number of downhole devices which require electrical power. In accordance with this technique, downhole devices which require power and are addressable will be at a low power consumption state (e.g., sleep or dormant mode). When requested by a downhole or surface controller, the downhole device will turn itself on to an active mode and perform its intended function or task (such as transmitting data, acquiring data, actuating a tool or the like). Preferably, only one downhole device is in its active mode at any one time. As a result of this power management technique, the power requirement downhole will be relatively low and substantially constant regardless of the number of downhole devices requiring power.

[ What is claimed is:] [1.] A method of managing power in a control system for the control and monitoring of a plurality of zones in at least one production well, the control system including a plurality of downhole modules which require power and are addressable, comprising:permanently deploying a downhole module which requires power and is addressable in each of the plurality of zones, each downhole module being operatively associated with at least one downhole device for controlling the downhole device;continuously maintaining each downhole module in a dormant, low power consumption mode until activation is desired; andselectively activating one or more downhole modules when activation is desired wherein the activated downhole modules will change state from a dormant, low power consumption mode to an active, higher power consumption mode.
