Abstract/Summary:


The Reunion Department, one of the local administrative bodies in Reunion Island, consumes a lot of electricity and aims to become an energy positive and carbon free institution. To reach its objective, it set up a program for the energy management and for the use of renewable energy, particularly from photovoltaics, in its property assets. Nevertheless, its vehicle fleet consumes a lot of fossil fuels, and the Department wants to explore the technical and financial feasibility of the conversion of this fleet to electricity, with the requirements of producing this energy with photovoltaics and not relying on the existing fossil fuel power plants. This study proposes a method to approach this kind of problem, which will arise in many various territories in the near future. It is shown that the sunny climate of Reunion allows the setup of a system covering all the needs of an electric fleet, with photovoltaics and energy storage systems compensating the intermittency of the photovoltaic production. Photovoltaics have to be sized for the season with the least solar resource to avoid big interseasonal electricity storage. The profitability of the system depends a lot on the ability of the Reunion Department to benefit from the international costs of photovoltaics and storage systems and on its possibility to use the overproduction of electricity, for example for the cooling of the buildings of the Department during summer. In the most favourable cases, the conversion to electric mobility looks technically and financially feasible.
