Powering the World with Clean Energy Reliable Renewables: wind, solar and hybrid solutions Keys to Success for Deployment of Renewable Power on Islands IRENA Forum 2015 Martinique 22-24 June 2015

3 Keys to Success for Deployment of Renewable Power on Islands Opportunities for Islands? Overview of successful RE developments Risk profile of renewable energy projects Is there an ideal RE investment scheme? Overcoming Islands challenges: Enabling environment Technical (case studies) Setting appropriate goals

7 Is there an ideal RE Investment scheme? Not a unique Scenario No fast track to success : Enabling environment necessary Cooperation between stakeholders Ensuring sustainability of the project : importance of capacity building ModelInvestment in Preliminary feasibility studies Land acquisition Project FundingConstructionOperation FIT/!\ PPA/!\ Utility/!\ or Grant/!\ or /!\

8 Setting clear RE objectives All stakeholders to go in the same direction Roadmaps, RE target… Cooperation between Utility, Public authorities, IPP … Adapt regulatory framework and Utility’s business model to increase RE share (IPP, distributed generation) compatible with the country’s RE objectives Initiating small & medium-scale RE projects: Many investors, few developers Facilitating the feasibility and resource assessment studies is decisive to the success of smaller projects (IRENA, FASEP, Development banks support, country support…) Overcoming Islands challenges Necessity for an enabling environment

19 Setting appropriate goals Grid Stability and power quality must drive the development of RE projects in islands Consumption : minimum and maximum loads, grid parameters Possibility of performing grid measurements, identify weak points, etc. Walk before running Set reasonable targets for penetration rates and have a step by step approach (ex: 1 turbine + 10, 30% penetration before targetting 70%) Grid stability : the project must be immediately a success Project a flexible system, able to adapt to the grid evolutions Possible evolutions of the consumption Integration in the plans for development of the infrastructures of the territory Capitalize on the potential of variable energy for Islands PV, Wind, low-medium penetration systems are on parity with diesel costs in most islands locations. Intermittent (Wind & PV) = 2/3 of planned generation in the Caribbean Quick deployment Mature, scalable technology: Possibility to improve the system and targets : technology is evolving fast
