REI Partner Countries

As more variable renewable energy comes online globally, finance is needed to help energy systems prepare for its rapid uptake. It is estimated that infrastructure investments will need to ramp up to $820 billion annually by 2030 to facilitate the decarbonization of power systems.

CIF’s Renewable Energy Integration investment program is the only multilateral platform designed to help developing countries prepare their national power systems for rapid and scaled adoption of renewables. 

Endorsed by the G7 in 2021, REI builds on CIF's nearly 15-year track record in climate finance mobilization for clean energy. It supports grid flexibility measures on both the supply and demand side in four key ways: scaling up renewable energy enabling technologies, enhancing readiness of energy infrastructure for renewables, supporting innovative business models, and improving power system and market design and operations. Approximately 60 developing countries—one-third of the world’s nations—have applied for CIF REI funding, with investment plans for Colombia, Brazil, Costa Rica and Fiji approved.
