Systems and methods for providing energy to sub-sea support equipment. Energy can be provided by diverting at least a portion of a fluid from a well producing system to sub-sea support equipment units that can be disposed in the vicinity of the sea-floor, sea-bed, or mud-line. The well producing system can include, but is not limited to, a water injection system, a gas lift system, or combinations thereof. A water injection system designed to provide pressure support to one or more wells can be modified to provide an operational power source to one or more sub-sea support equipment units.
