Renewable Energy Integration (REI)
RENEWABLE ENERGY INTEGRATION PROGRAM

SHIFT TO ZERO CARBON

The Renewable Energy Integration (REI) program is the world’s only climate finance program fully dedicated to supporting the upgrading and adaptation of national energy systems, to help developing countries harness the full potential of clean technologies.

Delivering renewables

To meet climate goals, the energy sector needs to rapidly shift from being fossil-based to zero-carbon. While the global capacity to generate renewable energy has rapidly expanded – by 84 percent from 2014 to 2022 alone – integrating these variable sources of energy into existing energy systems can be a costly and technically challenging process.

The REI Program helps emerging economies solve system-wide barriers preventing the integration of intermittent renewable energy into national grids. Through highly concessional funding, REI enables countries to build the efficient and effective energy systems needed to enable the large-scale deployment of solar and wind power.

The program fills a critical gap in the energy transition by funding power grid improvements, storage technologies, and other infrastructure and policy updates that can deliver clean power where and when it is needed.

ABOUT REI

"The opportunity to access concessional resources from the Renewable Energy Integration Program of the Climate Investment Fund (CIF) represents a unique opportunity for our country to continue increasing the use of renewable energy sources and diversifying our energy matrix while attending environmental, social and economic needs. This funding will allow us to mobilize important resources for future public and private investments, which are essential to achieve our national climate targets as well as future commitments acquired in the margins of the COP26. We are looking forward to work jointly with the CIF and their partners towards net-zero paths in the Colombian energy and mines sector."
Diego Mesa Puyo
Minister of Mines and Energy of Colombia
