Why energy-impact reporting fails to deliver clarity
By Staff Writer
In a moment when energy disclosure is becoming central to ESG integrity, African companies are under growing pressure from investors, regulators and development finance institutions to demonstrate how they use energy and how they transition toward low-carbon operations. Energy reporting is no longer a mere reputational exercise. It is materially tied to capital access, risk management and long-term viability.
Yet many firms struggle with inconsistent metrics, incomplete data, or superficial narratives. To build trust and strategic value, companies must align their energy‑impact reporting with global best practices — while also reflecting the realities of African energy systems and markets.
This edition of ESG Clinic answers a key question: What does strong, credible energy-impact reporting look like — particularly in African contexts — and how can firms embed it into their ESG strategy?
What strong energy-impact reporting actually involves
1. Ground energy metrics in materiality, not hype
Materiality is the bedrock of responsible ESG reporting. A strong energy report begins with a rigorous materiality assessment. Where are energy risks greatest? Which operations drive the most energy intensity? For many African firms, energy challenges are not only about carbon emissions, but also grid reliability, fuel costs and the resilience of supply chains.
Consider the case of Africa Oil Corp.: in its 2023 sustainability report, the company documented a double-materiality assessment in preparation for more stringent disclosure, including the financial risks associated with energy transitions.
Others, particularly in sectors such as data centres or infrastructure, must think beyond consumption to procurement strategies and grid risk.
2. Use robust, comparable, and credible metrics
Transparent energy reporting requires a consistent set of metrics. These should include:
- Total energy consumption (e.g., in GJ or MWh)
- Energy intensity (per unit of output, revenue, or staff)
- Breakdown of energy sources (renewable vs non-renewable)
- Emissions by scope (especially Scope 1 and 2)
- Year-on-year trends and improvements
In South Africa, for example, Thungela, a major coal producer, disclosed that energy intensity improved by 3.5% in 2024 compared to 2023 (from 15.33 MJ/tonne moved to 14.79 MJ/tonne) in its ESG report.
Thungela also details its use of renewable energy and its pathway to net zero, in line with TCFD practices.
These metrics are not only about environmental performance. They feed directly into financial risk assessment and long-term strategy.
3. Report on energy procurement and resilience, not just consumption
It is not enough to tell stakeholders how much energy you use. Companies must explain where that energy comes from and how they source it. This includes:
- On-site generation (e.g. solar, battery storage)
- Power purchase agreements (PPAs) with renewable developers
- Guarantees of origin or renewable certificates
- Risk mitigation for energy-security issues (e.g. when the grid is unreliable)
A powerful example comes from Serengeti Energy, a renewables developer operating across Africa. In its 2024 ESG report, the company describes its generation , spanning solar, hydro and battery projects, and how its energy model has evolved to balance commercial viability with sustainable impact.
By reporting procurement strategy clearly, Serengeti provides deeper insight than just “we consumed X MWh.”
4. Tie energy metrics to financial value and risk
Energy use and sourcing affect the bottom line. Good ESG reporting links energy data to financial outcomes by quantifying:
- Cost savings from energy-efficiency investments
- Returns on renewable energy assets
- Payback periods for emissions‑reduction projects
- Risk exposure under different energy-price scenarios
This is especially critical in markets where energy costs are volatile and grid reliability is variable.
Kenya offers a relevant illustration: according to the International Energy Agency (IEA), Kenya’s energy intensity has declined by 14 percent between 2010 and 2023, driven by both policy and efficiency interventions.
When companies align energy metrics with financial modelling, they speak the same language as investors.
5. Be candid about failures, constraints, and trade‑offs
True transparency means reporting both successes and setbacks. Stakeholders value honesty more than polished spin.
Take Equity Group, one of East Africa’s leading financial institutions. In its 2023 sustainability report, the bank noted a 9.7% reduction in energy consumption in Kenya, but also acknowledged increases in other regions (such as DRC) and explained intensity per employee.
This balanced disclosure helps users understand both progress and ongoing challenges.
6. Ensure independent assurance of energy data
To build credibility, companies should subject their energy data and disclosures to third-party assurance. Assurance should examine:
- Data collection and aggregation processes
- Emission‑factor calculations
- Scope and boundary definitions
- Forecasting assumptions and target-setting methodologies
Assurance elevates reports from marketing documents to strategic, trust‑worthy disclosures. It signals seriousness about ESG and energy integrity.
7. Tell a compelling strategic story, not just present numbers
High-quality reports do not just provide data. They contextualise it.
A best-in-class report includes:
- Leadership commentary on how energy strategy supports corporate purpose
- Clear, time-bound energy and emissions targets, with baselines
- Case studies showing operational changes — for example, how energy‑efficiency projects saved costs or reduced risk
- Dashboards or scorecards that track progress transparently
Serengeti Energy, again, does this well: its report links its technical energy assets (solar, hydro, storage) with its ESG mission and its commercial growth strategy.
This approach helps stakeholders see energy performance as a core part of the firm’s transformation story.
Why transparency in energy reporting matters more than ever in Africa
Rising regulatory expectations
As ESG disclosure frameworks evolve globally, African capital markets are catching up. The Global Reporting Initiative (GRI), for instance, has partnered with the Africa Securities Exchanges Association (ASEA) to help listed companies improve their sustainability disclosure.
Stronger governance improves transparency. A recent academic study shows that in sub‑Saharan Africa, corporate governance structures (especially ownership) significantly influence the quality of ESG disclosure.
Companies that get ahead of reporting expectations build their reputational capital and resilience.
Energy transition risk is financial risk
In South Africa, Thungela explicitly links its energy intensity reductions, renewable projects, and emissions trajectory with long-term value creation.
Meanwhile, sovereign and regulatory risk is real: Eskom, South Africa’s dominant power utility, is balancing its emissions targets with energy security demands as it responds to increasing demand and power blackouts.
Good energy reporting helps stakeholders assess how companies are managing both transition risks and physical energy risks — which is central to their valuation.
Africa’s energy landscape brings both opportunity and complexity
Kenya, for example, has made great strides in electrification. According to the IEA, electricity access in Kenya rose from just 37 percent in 2013 to 79 percent in 2023.
At the same time, decentralised energy models, such as solar mini-grids, are generating notable socio-economic impact in rural communities. A recent study found that in Kenya and Nigeria, communities connected to mini-grids saw significant improvements in productivity, income and gender outcomes.
This layered reality means companies operating in African markets must reflect both centralised grid strategies and distributed energy models in their reporting.
The bottom line
Companies that commit to transparent, auditable, and strategic energy reporting make better decisions, build stronger trust with investors, and unlock long-term resilience. That is especially true in African markets, where energy systems are diverse and evolving rapidly.
When energy disclosure is rigorous, credible and forward-looking, it becomes more than a compliance exercise. It becomes strategic leadership.
