The Overseas Private Investment Corporation (OPIC) and the US Trade and Development Agency (USTDA) have committed $20m to the US-Africa Clean Energy Finance (ACEF), an Africa-focused renewable energy initiative.

USTDA Director Leocadia I. Zak, said: "USTDA is proud of our efforts to link US industry expertise and financing to help develop clean energy across sub-Saharan Africa. We look forward to continuing to work with our partners from OPIC and State under the next phase of ACEF."

In December, USTDA, which links US businesses to global infrastructure opportunities, and OPIC, the US Government's development finance institution, reached commitment of 100% of the initial project funds administered under ACEF.

ACEF is an innovative program to support early-stage projects to catalyze private-sector investment in the renewable energy sector in sub-Saharan Africa.

ACEF-supported projects span a wide breadth of activities designed to address Africa's energy challenges, including large- and small-scale projects, both connected to central power grids and serving rural, off-grid communities.

Impactful renewable energy projects that are now progressing because of ACEF funds include a 150 megawatt Senegalese wind farm and a 12 megawatt run-of-the-river hydroelectric power facility in Rwanda.

Secretary of State Hillary Clinton launched ACEF at the UN Conference on Sustainable Development in 2012 with an initial investment of $20m.

At the US-Africa Leaders Summit in August 2014, Secretary of State John Kerry announced the US State Department's intention to invest an additional $10m.

The ACEF program is designed to help promising clean energy projects develop into viable candidates for financing by providing small amounts of early-stage funding for essential inputs, such as technical and feasibility studies.

ACEF serves a catalytic role to advance these projects and help attract private sector follow-on investment, which can help to fuel low-carbon economic growth in the region.

Since the program's launch, OPIC and USTDA have committed funds to 30 renewable energy projects across 10 African countries.

The funding from OPIC and USTDA has the potential to lead to more than 400 megawatts of new renewable power in Africa and could mobilize more than $1.5 billion in project capital, a ratio of $75 for every $1 from the ACEF program.

Elizabeth Littlefield, OPIC's President and CEO, said: "Empowering private investors to lead the way in overseas development is at the heart of OPIC's mission, as well as that of President Obama's Power Africa initiative, in which we also effectively partner with USTDA."

"ACEF is a forerunner in realizing the potential of these private investors, and has helped innovative developers of clean, renewable energy in Africa advance their ideas to receive the financing they need," she said.
