There is provided a multilateral well and electric transmission system comprising a branch well tubular in a branch wellbore which is connected in an electrically conductive manner to a primary well tubular in a primary wellbore such that the primary and branch well tubulars form a link for transmission of electrical power and/or signals between the primary and branch wellbores. Low voltage electrical power can be transmitted from the surface to a battery in the branch wellbore to trickle-charge the battery and signals from battery-actuated measuring and control equipment in the branch wellbore can be transmitted back to surface via the walls of the electrically interconnected primary and branch well tubulars.
