  Distributed energy resources behind the meter and automation systems enable
traditional electricity consumers to become prosumers (producers/consumers)
that can participate in peer-to-peer exchange of electricity and in retail
electricity markets. Emerging prosumers can provide benefits to the system by
exchanging energy and energy-related services. More importantly, they can do so
in a more honest and more competitive way than the traditional
producer/consumer systems. We extend the traditional Cournot model to show that
the dual nature of prosumers can lead to more competitive behavior under a game
theoretic scenario. We show that best response supply quantities of a prosumer
are usually closer to the competitive level compared to those of a producer.
