Abstract

The context of the French overseas territories is particular. Those territories are off the main grid. This implies relying on an expensive and CO2 rich energy mix for electricity generation. Nevertheless, the tariff equalization mechanism keeps the price of the kWh exactly the same as the one in France mainland. The difference is covered by a tax paid by all the French consumers.

In such a context, the benefits of reducing the consumption of electricity are even more relevant. To do so and set up the appropriate actions and policies, a local knowledge is needed.

USER (Usages Spécifiques de l’Electricité à la Réunion) is a three-year project (2019-2022) funded by the French environmental Agency ADEME. USER aims at improving the knowledge about the households’ use of electricity for their appliances on the Réunion Island. A deep understanding of the Island households is the path to success for relevant actions that will be accepted and preserve as much as possible the wellbeing and the local ways of life.

In this paper, we will present the project and discuss the main results of two of its parts. A quantitative survey focusing on the knowledge of the Reunion households’ appliances and a monitoring campaign conducted on a sample of 45 Réunion Island households. Their cold appliances were targeted in the first place because they remain a major electricity consumption but not only. Up to five appliances were separately monitored for each participant. Active power was recorded every six seconds during a whole month. In contrary to simple energy measurement, this short time step allowed us to see precisely what is really happening at the appliance scale: is there a malfunction? Is the use intensity too high?... Results from these analyses provide insights for local decision-makers (ADEME and EDF Réunion) to address households in a tailored manner. Main intervention included replacing the appliance or giving the right advice to optimize its use.
