This document provides an update on the scope and objectives of the CIGRÉ Study Committee C6 on Distribution Systems and Dispersed Generation. It covers the assessment of technical impacts and requirements of widespread adoption of DG and variable generation, solutions in the short, medium, and long term, and issues like rural electrification and demand-side management. It also includes information on working groups, publications, preferential subjects, and upcoming events.
