On the Viability of Energy Communities
Présentation

EPRG Working Paper 1716, Cliquez ici

Following the development of decentralized production technologies, energy communities have become a topic of increased interest. While the potential benefits have been described, we use the framework of cooperative game theory to test the ability of such communities to adequately share the gains. Indeed, despite the potential value created by such coalitions, there is no guarantee that they will be viable: a subset of participants may find it profitable to exit the community and create another one of their own. We take the case of a neighborhood, having access to a limited resource – e.g. a shared roof or piece of land – which they can exploit if they invest in some renewable production capacity. By joining the community, participants also enjoy aggregation gains in the form of reduced network fees. We find conditions depending on the structure of renewable installation costs, on the magnitude of the aggregation effect and coordination costs and, most importantly, on the chosen sharing rule, under which the whole energy community is stable. Efficiency could require the intervention of a social planner or a change in network tariff structures.

Costing Network Services for Consumers with PV Self-Generation
Présentation

The adoption of self-generation can offer a substantial reduction of the network bill to consumers whereas their PV production covers only part of their needs. This raises equity and efficiency issues, related to network costs allocation among customers, which points towards a need for a better identification, costing and pricing of the different services provided by the distribution grid. The paper adopts a costing perspective based on a probabilistic methodology. It relies on a splitting of cost between operational costs and capital amortization costs among network access, network sizing costs (related to the services of guaranteed power, energy withdrawal and voltage quality) and energy losses costs. It takes into account the cost related to the fact that power demand in lower voltage levels implies energy transit from upper voltage levels. We obtain the expected cost that is to be allocated to every client connected to any grid circuits of the distribution system. This methodology provides an estimate of billable network costs attributed to consumers according to their loads, with a focus on the difference between clients with/out self-consumption.
