A device for supplying hydraulic pressure to one or more hydraulically actuable components in a well production system and positioned within the well bore including a reservoir, and electrically powered pump, and a controller each positioned within the well bore and carried on the component. The controller operates the pump to supply fluid from the reservoir to actuate the components. Additionally, valves to route the fluid to the components and sensors to sense when the components are actuated are included.

1. A subsea apparatus for performing a task on a subsea wellhead assembly located adjacent to a sea floor at an upper end of a well, the wellhead assembly having a riser extending to a platform at a surface of the sea, the apparatus comprising:a first hydraulically actuable component adapted to be lowered from the platform through the riser into engagement with the subsea wellhead assembly above the well for actuating a member of the subsea wellhead assembly; a reservoir containing a fluid and carried by the first component; an electrically powered pump carried by the first component for pumping fluid from the reservoir to the first component to actuate the first component; and an electrically actuable controller carried by the first component for receiving remote signals from the platform and electrically operating the pump.
