Energy self-sufficiency for noninterconnected areas

Up to 2030
Energy autonomy of non-interconnected zones
Context & Issues

At the request of the French Environment and Energy Management Agency (ADEME), our teams studied the technical, organisational and economic implications of an electricity mix containing a large proportion of renewables (75% to 100%) up to 2030 for France’s island regions (Réunion, Guadeloupe, Martinique, Mayotte, Corsica, French Guiana). An innovative approach blending technical and political considerations was adopted to transpose each region’s socioeconomic objectives into consumption scenarios and then seek the production, distribution and storage solutions capable of
achieving them. This process has been finalised for all six regions and shown that a 100% renewable electricity mix is technically possible provided that certain conditions (demandside management, sufficient storage capacity) are met.

Project characteristics

Evaluation of the technical, organisational and economic implications of mixed energy production with a high proportion of renewables (75% to 100%) considering the period up to 2030:

  • Evaluation of the constraints involved in the production of electricity from 75% to 100% renewable sources 
  • Definition of optimal production facilities and identification of the geographical distribution of these facilities
  • Evaluation of the average cost of electricity (LCOE) and its impact on the CSPE electricity tax
  • Evaluation of requirements in terms of network infrastructure, balancing measures and system services
