How Just Energy Transition Partnership (JETP) funding works
88 matching capital sources on the AESFIP database · Last checked October 2026
Just Energy Transition Partnerships are packages agreed between a developing country and a group of donor governments and development banks to speed the move away from coal. Headline numbers are large, but most of the money is sovereign loans, guarantees and commercial finance — not grants available to private developers.
This guide explains how JETP finance flows in South Africa, Indonesia, Vietnam and Senegal, which parts private renewable, grid and just-transition projects can realistically reach, and the funders on our database active in energy transition.

Sovereign versus private windows
Most JETP money goes through government balance sheets and state utilities. Private projects reach it indirectly.
- Sovereign and utility loans for grid, coal retirement and policy reform.
- Guarantees and risk instruments that make private renewable projects bankable.
- Commercial bank and DFI lending to private generators under competitive procurement.
- Smaller grant envelopes for just-transition skills, communities and project preparation.
How private developers engage
Follow the country investment plan, government procurement rounds and the development banks named as JETP partners. Bring projects that fit the plan's priorities, such as renewable generation, transmission and storage.

- The Carbon Initiative for Development (Ci-Dev)Climate FundThe Carbon Initiative for Development (Ci-Dev) is a World Bank trust fund that mobilizes private finance for clean energy access in low-income countries. It delivers results-based finance to innovative and transformative business models driven by the private sector. Ci-Dev comprises two reinforcing components, the Readiness Fund and the Carbon Fund. The Readiness Fund finances capacity building activities in least developed countries to develop standardized baselines and technical assistance for energy access programs. It supports the development of new methodologies and proposals for simplified Clean Development Mechanism (CDM) rules, and dissemination of results. Where needed, it also provides technical assistance to the projects and programs supported by the Carbon Fund. The Carbon Fund provides performance-based payments to low-carbon investments in the form of purchases of certified carbon emission reductions.Technical AssistanceCarbon Credits / ERPA
- Mitigation Action FacilityClimate FundThe Mitigation Action Facility is a go-to platform providing technical support and climate finance for ambitious mitigation projects with the aim of decarbonising key sectors of the economy and society. The Mitigation Action Facility funds ambitious climate change mitigation projects to implement Nationally Determined Contributions (NDCs) and long-term strategies (LTS) that are crucial for achieving the Paris Agreement goals. The Call for Projects 2026 will offer climate finance for the implementation of mitigation projects aligned with new ambitious NDCs. While the Mitigation Action Facility primarily focuses on three priority sectors, it remains open to cross-sectoral projects linked to one of the priority sectors. As highlighted in the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) , energy, transport and industry together account for 73% of global annual greenhouse gas (GHG) emissions (as of 2021). To shift the targeted sectors towards a carbon-neutral development pathway, the Mitigation Action Facility selects innovative projects that can catalyse sector-wide transformational change. These efforts can help ܪll the shortfall in climate finance required to avoid the worst impacts of climate change.

- The Green Guarantee Company (GGC)Climate FundThe vast majority of institutional capital in developed capital markets is only available to investment grade borrowers. The Green Guarantee Company is tackling the issue of emerging market countries often being rated below investment grade by international credit rating agencies Moody’s, Standard and Poor’s and Fitch. By providing investment grade guarantees to improve the credit rating of borrowers in emerging markets, the Green Guarantee Company will unlock larger pools of capital to finance climate adaption and mitigation projects.Technical Assistance
- Transformative Carbon Asset Facility (TCAF)Climate FundThe Transformative Carbon Asset Facility (TCAF) is a World Bank trust fund designed to support developing countries in implementing market-based carbon pricing mechanisms and creating the conditions for private sector investment in low-carbon technologies. TCAF offers an innovative hybrid funding structure—mobilizing both climate finance and carbon market funding for payment against emission reductions.Technical Assistance

- CIF - Scaling up Renewable Energy in Low Income Countries Program (SREP)Climate FundThe Scaling up Renewable Energy in Low Income Countries Program (SREP) is one of three targeted programs that make up the Strategic Climate Fund (SCF) of the Climate Investment Funds (CIFs). SREP empowers transformation in developing countries by demonstrating the economic, social and environmental viability of renewable energy. Channeled through five multilateral development banks (MDBs), SREP financing supports scaled-up deployment of renewable energy solutions to increase energy access and economic opportunities, with a focus on low-income countries. SREP also contains dedicated Private Sector Set Asides (PSSAs), which allow concessional financing to projects that engage the private sector. It has five objectives: Assist low income countries foster transformational change to low carbon pathways by exploiting renewable energy potential; Highlight economic, social and environmental co-benefits of renewable energy programs; Help scale up private sector investments to achieve SREP objectives; Enable blended financing from multiple sources to enable scaling up of renewable energy programs; and Facilitate knowledge sharing and exchange of international experience and lessons SREP’s targets include: Generating over 3 million MWh per year of renewable energy Improving access to energy for over 140,000 businesses and 17.3 million people Reducing 2.5 million tons of GHG per year.Concessional DebtDebtGrants
- CIF- Clean Technology Fund (CTF)Climate FundThe Clean Technology Fund (CTF) is part of the CIF, which were originally designed with a ‘sunset clause,’ stipulating that operations would wind down once a new financial architecture under the UNFCCC, such as the Green Climate Fund (GCF), became fully operational. The clause allows for any remaining CTF funds to be transferred to a fund with similar objectives. However, given ongoing demand, a strong implementation track record, and the complementary role of the CIF alongside the GCF, the CTF continues to operate with new programming approved by its governing body. As of now, there is no active plan to implement the sunset clause or transfer remaining funds. The CTF promotes scaled-up financing for the demonstration, deployment, and transfer of low-carbon technologies with strong potential for long-term greenhouse gas emissions reductions. Its objectives include: Provide positive incentives, through public and private sector investments, for the demonstration of low carbon development and mitigation of greenhouse gas emissions Fund low carbon programmes and projects that are embedded in national plans and strategies, scaling up development and accelerating the diffusion and transfer of clean technologies Realise environmental and social co-benefits, illustrating the potential for low-carbon technologies in contributing to sustainable development and the Millennium Development Goals Support international cooperation on climate change Utilise skills and capabilities of the MDConcessional DebtDebtGrants
- Multilateral Fund for the Implementation of the Montreal ProtocolClimate FundThe Multilateral Fund was set up by the Parties to the Montreal Protocol to assist developing countries to comply with the terms of the Montreal Protocol, an international agreement that sets out a timetable for the phase-out of ODS in both developed and developing countries. The Multilateral Fund provides assistance to countries that are Parties to the Montreal Protocol and whose annual per capita consumption and production of CFCs and halons is less than 0.3 kg on the date of entry into force of the Montreal Protocol or any time thereafter until 1 January 1999. The developing countries that meet these criteria are referred to as Article 5 countries. Contributions to the Multilateral Fund are provided by the non-Article 5 countries. The Kigali Amendment, which was adopted at the Twenty-eighth Meeting of the Parties to the Montreal Protocol (MOP) on 15 October 2016, added HFCs, non-ODS greenhouse gases that do not damage the ozone layer but have a high global-warming potential (GWP), to the list of substances controlled under the Protocol. The Kigali Amendment entered into force on 1 January 2019. As at 5 February 2020, it has been ratified by 93 Parties. The Montreal Protocol’s timetable for the phase-down of HFCs in both Article 5 and non-Article 5 countries is set out in Annex F of the Protocol. A group of 17 non-Article 5 Parties has provided fast-start support for the implementation of the Kigali Amendment, that is additional to their regular contributions to the Fund. TGrants
