ICT has become a crucial element in supporting energy management. It allows for design and implementation of smart grids. In this paper we present a distributed solution for improving the efficiency for electricity distribution and for more rational use of energy, minimizing overloads and voltage variations. It is implemented by a Virtual Market that has been built according to a distributed approach over a P2P server-less overlay. In our prototype, RetroShare is used to implement a F2F (Friend-To-Friend) network where intelligent agents can broker and negotiate energy autonomously on user's behalf according to high level policies are discussed.
