Optimal grid tariffs with heterogeneous prosumers

Abstract

Energy consumers can invest in photovoltaic (PV) panels and become prosumers. The benefit of such an investment depends on the regulatory framework. We consider a population of heterogeneous consumers, with respect to both the cost of decentralized production and their degree of self-consumption.it is efficient to have investment by low-cost and high self-consumption profiles. We determine the optimal tariff in the presence of heterogeneous prosumers. Net metering fails to screen consumers on the self-consumption dimension. Net purchasing can lead to the efficient investment if the tariffs are non-Coasian that is fixed fees exceed the grid operator’s fixed costs.
