ISLAND CASE: MARTINIQUE
BENEFITS AND LIMITS OF VARIABLE RE INTEGRATION
Benefits from increasing share of PV generation
Stable prices
Local jobs
Little global CO2 emissions (no local emissions) and little local pollution
Limits to a higher integration of PV: 30% limit
French law (23 april 2008): TSO can disconnect variable RE generation in
case of instantaneous power exceeding 30% of total load
Currently around 24% (some French islands > 35%)
Source: EDF SEI
WHAT ARE THE ISSUES RELATED TO THE
INTEGRATION OF VARIABLE RENEWABLES ?
Little issues for integration up to around 30-40% of instantaneous RE power in a grid
