Consumers having capabilities of Distributed Electricity Generation, through renewable sources of electricity, are known as Prosumers, in the context of electric electricity generation. Trade occurs between the prosumers when the excess electricity generated by some prosumers is sold, at a price that is lower than the one that one pays for buying from the electricity grid to other prosumers having deficit production. This trading between the prosumers is not only beneficial to the seller and buyer but also to the environment as most electricity grid companies use fossil fuel to generate electricity as the prosumers use renewable sources of energy in the form of solar electricity. This paper uses a simulation model, based on aggregate data available from different domestic and commercial facilities of Kolkata, to develop a framework for electricity trading between prosumers. Our model shows the both commercial viability of such a peer-to-peer trading network and the environmental sustainability of such models.
