The global development lobby has found its favorite scapegoat, and it is the big three credit rating agencies.
For years, the narrative surrounding clean energy infrastructure in Africa has been stuck on repeat. The conventional wisdom states that the continent is ready for an unprecedented green boom, but standard credit risk metrics are too rigid, too Western-centric, and unfairly punitive. Critics claim that if Moody’s, S&P, and Fitch would just loosen their sovereign risk methodologies, billions of dollars in institutional capital would suddenly flood African solar, wind, and hydro projects.

This argument is comfortable. It is also entirely wrong.
Blaming credit rating rules for the financing bottleneck in African renewable energy is a lazy deflection. It mistakes the thermometer for the disease. The hard truth is that credit ratings are accurately reflecting structural, deep-seated risks that no amount of methodology-tweaking can erase. If you want to fix the clean energy deficit, you have to stop demanding softer grading scales and start fixing the underlying economics of the projects themselves. Additional analysis by Business Insider explores comparable views on the subject.
The Flawed Premise of Unfair Risk
The core of the mainstream argument relies on a comforting myth: that African sovereign risk is artificially inflated. Advocacy groups frequently point to the fact that African nations often pay a premium to borrow on international markets compared to European or Asian peers with similar debt-to-GDP ratios. They argue that traditional rating agencies overrate the political instability and currency risks of emerging markets while underrating their growth potential.
Let us look at the mechanics of utility-scale energy projects. Infrastructure investment is built on predictability. A typical power purchase agreement (PPA) spans twenty to thirty years. Over that multi-decade horizon, an investor must be certain of three things: that the state-owned utility will pay for the power generated, that the local currency will retain its value or convert easily, and that the regulatory framework will not change overnight.
When rating agencies look at these factors across many sub-Saharan jurisdictions, they do not see a hidden paradise of low risk. They see structural realities.
Consider the off-taker risk. In most African nations, the sole buyer of electricity is a state-owned national utility. Many of these entities are financially insolvent, propped up only by periodic government bailouts. When a state utility cannot balance its own books, it cannot guarantee payments to an independent power producer (IPP). Credit rating agencies are not being unfair when they penalize a project dependent on a bankrupt state monopoly; they are doing their jobs. If an agency gives a AAA rating to a project whose primary customer is deeply in debt, that agency is committing fraud.
The Currency Mismatch Trap
The second structural barrier that the "fix the ratings" crowd ignores is the brutal reality of currency volatility.
Most international green energy financing is denominated in US dollars or Euros. However, the electricity produced by these wind farms and solar arrays is sold to local consumers in local currency—whether it is Nigerian Naira, Kenyan Shillings, or Ghanaian Cedis.
Imagine a scenario where a developer borrows $100 million to build a solar plant in a country where the local currency depreciates by 30% against the dollar over a two-year period. Suddenly, the project needs to generate 30% more local revenue just to service the exact same dollar-denominated debt. To cover this gap, the developer must either raise electricity tariffs to politically unpalatable levels or default on the loan.
The rating agencies do not create this currency mismatch. They merely quantify it. Loosening rating definitions does nothing to protect an investor from the math of a collapsing local currency.
Why Lowering the Bar Hurts the Long-Term Market
Let us indulge the critics for a moment. Suppose the major rating agencies capitulate to political pressure and artificially upgrade African sovereign and project ratings by two or three notches. What happens next?
The institutional capital that activists hope to attract—pension funds, insurance companies, sovereign wealth funds—does not just blindly follow an alphabet-soup rating letter. These funds employ their own internal risk analysts. They read the financial news. They understand macroeconomics.
If institutional investors perceive that credit ratings have been decoupled from underlying economic realities due to political correctness or development mandates, they will not invest more. They will pull back entirely. They will lose trust in the metrics. By trying to manipulate the ratings to look more favorable, you destroy the credibility of the entire market ecosystem.
I have watched well-meaning development finance institutions spend millions trying to structure synthetic vehicles that mask these fundamental flaws. The result is almost always the same: complex, high-fee structures that look great in a press release but fail to scale because the foundational risk remains unchanged.
Redefining the Problem: Fix the Off-Taker, Not the Rating
If the goal is truly to scale up clean energy deployment, the global financial community needs to stop asking how to bypass rating rules and start asking how to de-risk the projects fundamentally.
Instead of subsidizing rating studies or lobbying for rule changes, development capital should be ruthlessly targeted at structural reforms:
- Utility Privatization and Reform: Dismantle the broken state-owned monopolies. Allow corporate power purchase agreements where private green energy developers can sell directly to mining companies, industrial hubs, or commercial centers without going through a failing state grid.
- Localized Capital Markets: Build deeper domestic capital markets within Africa so projects can borrow in local currencies. If a solar project in South Africa borrows in Rand and sells power in Rand, the currency mismatch risk vanishes entirely.
- Targeted Blended Finance: Stop using development finance to write reports. Use it to provide robust, long-term currency hedging instruments and first-loss guarantees that genuinely absorb the specific risks commercial banks cannot take.
The obsession with credit rating methodologies is a distraction designed by institutions that want to appear active without doing the heavy lifting of economic reform. A high risk rating is not a barrier; it is a diagnostic tool. If you do not like what the diagnostic tool is telling you, you do not break the tool. You treat the patient.
