SECNIR: A Multi-Year Electricity Consumption Dataset of 881 French Companies in Islands and Overseas Regions

This paper presents the Survey of Electricity Consumption in Non-Interconnected Regions (SECNIR), a multiyear electricity consumption dataset comprising data from 881 companies and local authorities in French overseas regions. To the best of our knowledge, it is the first large-scale electricity consumption open dataset for professionals in islands and overseas regions at the level of individual electricity meters. The dataset includes electricity consumption, weather, and indoor comfort data from a variety of professionals in six different French islands and overseas regions: Reunion Island, French Guiana, Martinique, Guadeloupe, Corsica, and Mayotte. We analyze how local climate influences electricity consumption, in particular in tropical regions. Additionally, we provide insights into the most power-intensive sectors and examine the variability of energy consumption within specific professional sectors.
