The Small Island Developing States (SIDS) Lighthouses initiative (LHI) is a framework for action to support SIDS in the transformation from predominantly fossil fuel dependence to a renewables-based and resilient energy system. SIDS LHI brings together 38 SIDS as well as 31 partners, including developed countries, regional and international organisations, development and multilateral agencies, private companies, research institutes and non-profit organisations. IRENA is the coordinator and facilitator of the initiative.

Launched at the United Nations Climate Summit in 2014, the initial LHI targets for 2020 have been met and exceeded ahead of schedule. Taking into consideration the commitments of SIDS and development partners, and the evolution of the energy context, new priority areas and target have been identified and endorsed by partners in a high-level meeting held at the United Nations General Assembly in New York in September 2018

The new priority areas of the SIDS Lighthouses Initiative are:

  • Support SIDS in reviewing and implementing Nationally Determined Contributions (NDCs), extending technical assistance and capacity building where needed.
  • Expand from assessment and planning to implementing effective, innovative solutions, with continued technical and regulatory advisory services to help SIDS overcome the unique challenges they face.
  • Promote all renewable sources, including geothermal and ocean energy, and step up work to integrate solar PV and wind power.
  • Support the development of bankable projects, fostering access to finance and closer co-operation with the private sector.
  • Strengthen institutional and human capacity development in all segments of the renewable energy value chain.
  • Expand focus beyond power generation to include transportation and other end-use sectors.
  • Leverage synergies between renewables and energy efficiency.
  • Reinforce links between renewables and non-energy sectors - including agriculture, food, health and water - to foster broad socio-economic development, as well as raising awareness about job creation, gender equality and women's empowerment through renewable energy development.
  • Link renewable energy uptake to climate resilience and more effective disaster recovery.
  • Enhance collection and dissemination of data and statistics, supporting informed decision-making and effective monitoring.
  • Reinforce and expand partner engagement, leveraging synergies with existing SIDS initiatives and other IRENA co-ordinated platforms, such as the Global Geothermal Alliance, the International Off-Grid Renewable Energy Conference and the Coalition for Action.
  • Boost renewable power deployment, aiming for a target of ten (10) gigawatts (GW) of total installed RE capacity in all SIDS by 2030

Taking account of the success in reaching its previous targets, the SIDS LHI has revised its 2030 target for installed renewable energy capacity, updating it to 10 GW. This new target has informed the new IRENA-AOSIS Energy Compact, prepared in cooperation by IRENA and the Alliance of Small Island States (AOSIS) and operationalized by the SIDS LHI. Moreover, this new target will also guide the two other initiatives operationalised by SIDS LHI: the Initiative for Renewable Island Energy (IRIE) and the Ambitious SIDS Climate Action Summit Package.


RE Progress

The strong political commitment of SIDS and the remarkable cost reductions in technologies such as solar PV and onshore wind, coupled with the support of a wide range of partners, have made renewables an affordable solution for countries with limited financing and technical capabilities.
