South Africa‘s energy transition has entered a new phase with the approval of a $400 million African Development Bank (AfDB) loan backed by the United Kingdom. The funding targets one of the country’s most pressing problems: ageing electricity and water infrastructure in Mpumalanga Province, the heart of South Africa’s coal economy.
The package is more than another development loan. It combines international financing, policy reform, performance-based accountability and climate goals into a single programme. If implemented successfully, it could improve municipal governance, strengthen energy security, reduce water losses and provide a practical model for infrastructure reform across South Africa.
The project also demonstrates how international climate finance is evolving. Instead of financing only renewable energy projects, development partners are increasingly supporting the institutions that deliver electricity and water services. Strong utilities remain essential for any successful energy transition.
According to the African Development Bank, the financing will support the Mpumalanga Municipal Utility Reform Programme, with loan disbursements linked to independently verified results rather than spending alone. The United Kingdom is providing a guarantee through the Just Energy Transition Partnership (JETP) alongside technical support during programme design.
Why the choice of Mpumalanga
Few provinces are more central to South Africa’s energy future than Mpumalanga.
For decades, the province has supplied much of the country’s electricity through coal-fired power stations operated by Eskom. While coal has powered economic growth, it has also created environmental pressures and left many municipalities dependent on ageing infrastructure.
South Africa now faces three connected challenges.
First, electricity networks require urgent modernisation after years of underinvestment.
Second, municipal water systems suffer from leaks, poor maintenance and financial weakness.
Third, communities dependent on coal need new economic opportunities without sacrificing jobs and public services.
The Mpumalanga programme attempts to address all three challenges simultaneously.
The initiative will benefit approximately 1.2 million residents across eMalahleni, Lekwa, Govan Mbeki and Mbombela between 2026 and 2031.
Results-Based Financing Changes the Rules
Perhaps the most innovative element of the programme is its financing structure.
Traditional infrastructure loans normally release funds according to project milestones or procurement schedules. The AfDB programme takes a different approach.
Money will be released only after independently verified improvements in service delivery have been achieved.
According to the African Development Bank, this results-based financing approach “links disbursements directly to verified improvements in service delivery,” creating stronger incentives for accountability and measurable outcomes.
This approach reduces the risk of inefficient spending while encouraging municipalities to improve operational performance rather than simply completing construction projects.
For investors, development partners and taxpayers, that creates greater confidence that public funds will produce measurable improvements.
The UK’s Strategic Role
The United Kingdom’s involvement extends well beyond financial support.
Through the Foreign, Commonwealth and Development Office (FCDO), the UK is providing a loan guarantee under the Just Energy Transition Partnership. It also helped design the programme through technical assistance.
The Just Energy Transition Partnership was launched to help South Africa reduce its dependence on coal while protecting workers and communities affected by the transition.
According to the UK Government, the partnership supports South Africa’s efforts to secure cleaner energy, strengthen economic resilience and attract private investment into climate-related infrastructure.
The guarantee also lowers financial risk for the African Development Bank, making large-scale financing more accessible.
Beyond Electricity: Water Infrastructure Takes Centre Stage
Energy headlines often dominate discussions about South Africa, yet water infrastructure presents an equally urgent challenge.
Many municipalities lose large volumes of treated water through leaking pipelines, ageing equipment and illegal connections.
The Mpumalanga programme addresses these weaknesses through several practical investments, including:
Smart electricity metering.
Customer audits.
Rehabilitation of electricity networks.
Water network upgrades.
LED street lighting.
Alternative energy systems for public buildings.
Measures to reduce non-revenue water.
Reducing water losses improves municipal finances while increasing water availability without constructing expensive new dams.
That makes infrastructure efficiency one of the most cost-effective investments available.
Stronger Municipal Utilities Support Economic Growth
Reliable electricity and water services remain basic requirements for economic development.
Manufacturers require stable power.
Farmers depend on reliable water supplies.
Small businesses cannot expand if electricity interruptions continue.
Municipal reforms therefore extend beyond infrastructure.
Better billing systems, improved revenue collection and stronger governance can increase financial sustainability, allowing municipalities to maintain assets without depending entirely on national government support.
The programme also assigns implementation to the Development Bank of Southern Africa (DBSA) in partnership with the National Treasury and the Department of Cooperative Governance, creating institutional oversight across different levels of government.
Climate Finance Is Becoming More Practical
Global climate finance has often attracted criticism for focusing heavily on renewable energy generation while overlooking local institutions responsible for delivering public services.
This programme adopts a broader approach.
Modern electricity networks make renewable energy integration easier.
Efficient water systems strengthen climate resilience during droughts.
Financially healthier municipalities become more attractive to private investors.
In effect, infrastructure reform becomes climate policy.
That integrated approach aligns with broader international development priorities promoted by institutions including the World Bank, the African Development Bank and partners supporting South Africa’s Just Energy Transition.
Challenges That Could Determine Success
Although the programme offers strong potential, implementation will determine its long-term impact.
Municipal capacity varies widely across South Africa.
Procurement delays remain common.
Political leadership can change during long-term infrastructure programmes.
Maintaining independent verification will therefore be essential.
Transparency, public reporting and continuous technical support will help sustain credibility throughout implementation.
Another challenge involves balancing coal phase-down policies with employment protection. Communities dependent on mining require investment in new industries, skills development and local enterprise if the transition is to remain socially sustainable.
A Blueprint for South Africa’s Future
The Mpumalanga Municipal Utility Reform Programme could become one of South Africa’s most influential infrastructure initiatives in years.
Its combination of performance-based financing, international guarantees, municipal reform and climate investment offers a practical model that other provinces could adopt.
If successful, the programme could improve electricity reliability, reduce water losses, strengthen municipal finances, attract additional development finance and support South Africa’s long-term energy transition.
The UK’s backing of the $400 million AfDB funding therefore represents more than financial cooperation. It demonstrates growing international confidence that infrastructure reform, accountability and climate policy can work together to deliver better public services.
For South Africa, the real measure of success will not be the size of the loan. It will be whether households experience fewer power interruptions, cleaner water systems, stronger local government and greater economic opportunities. If those outcomes are achieved, Mpumalanga could become the national benchmark for municipal reform and a compelling example of how climate finance can produce measurable benefits for ordinary citizens.
