- KOKO Networks deployed the Teka Smart bioethanol cooking system in Rwanda through a $25 million partnership with the Rwanda Development Board, positioning it as the country's primary clean cooking alternative to charcoal.
- The system demonstrated strong environmental and economic benefits — cutting household cooking emissions by an estimated 60–80% and offering more predictable fuel pricing than charcoal markets.
- In early 2026, KOKO abruptly paused Rwanda operations, leaving thousands of households without fuel and exposing a critical fragility in centralised clean energy models.
- Our analysis shows the collapse was not a technology failure — it was a systems resilience failure: the model was optimised for scale but not engineered for continuity under financial or logistical stress.
- The Rwandan case holds lessons for every clean cooking transition across Africa: distributed redundancy and adaptive supply chains are as important as the technology itself.
1. Context & background — why clean cooking matters in Rwanda
Sub-Saharan Africa faces one of the most persistent energy access challenges in the world. Across the continent, an estimated 900 million people still cook primarily with solid biomass — charcoal, firewood, or agricultural waste. In Rwanda, the picture is sharp: despite the country's remarkable post-1994 development trajectory, the majority of urban and peri-urban households relied on charcoal as their primary cooking fuel as recently as 2022.
This dependency has cascading consequences. Rwanda loses approximately 30,000 hectares of forest annually to charcoal production and agricultural expansion, according to Rwanda Environment Management Authority (REMA) estimates. The country's hills — iconic for their terraced green ridgelines — are under sustained pressure from biomass energy demand that formal grid expansion has not yet replaced. In Kigali specifically, charcoal combustion contributes meaningfully to indoor and ambient air pollution in densely populated informal settlements, where respiratory disease rates among women and children who spend the most time near cooking fires are disproportionately high.
Into this context, KOKO Networks arrived with a proposition that was technically elegant: replace the informal, fragmented charcoal market with a digitally managed, pay-as-you-go bioethanol fuel ecosystem. The timing was right. Rwanda's government had committed to ambitious clean cooking targets under its updated Nationally Determined Contributions (NDCs) to the Paris Agreement, and the Rwanda Development Board was actively seeking private sector partners to accelerate the energy transition.
Key fact: In 2022, Rwanda and KOKO Networks signed a landmark agreement to develop a nationwide renewable cooking fuel utility — the first of its kind on the continent — backed by $25 million in public-private investment. (Rwanda Development Board, 2022)
2. How the Teka Smart system works
The Teka Smart system is not simply a stove — it is a vertically integrated energy utility built around three interlocking components: the cooking device, the fuel distribution infrastructure, and the digital payment layer. Understanding how these three elements interact is essential to understanding both why the system worked well when it did, and why it collapsed when it did.

Bioethanol chemistry — why it burns cleaner
Bioethanol (C₂H₅OH) combusts according to the reaction: C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O. The key distinction from charcoal combustion is the absence of particulate matter, carbon monoxide spikes, and polycyclic aromatic hydrocarbons (PAHs) — the toxic byproducts of incomplete biomass combustion that cause the majority of household air pollution-related illness. Bioethanol combustion is near-complete under normal conditions, producing primarily carbon dioxide and water vapour.
The feedstock for KOKO's ethanol in the East African context is largely sugarcane molasses — a byproduct of sugar production that would otherwise be treated as industrial waste. This circular feedstock logic is part of what makes the near-closed carbon cycle argument credible: the sugarcane absorbs CO₂ during growth, and the combustion releases approximately equivalent CO₂, making lifecycle emissions substantially lower than fossil fuels and significantly lower than inefficient charcoal kilns.

3. Impact analysis — economic, environmental, and social
- Pay-as-you-go eliminates large upfront fuel purchases
- More stable pricing vs. seasonal charcoal fluctuations
- Small-increment purchasing improves cash-flow for low-income households
- Employment created in distribution, ATM maintenance, and retail
- Risk: total dependency on one supply chain — no market fallback
- ~60–80% reduction in household cooking emissions vs. charcoal
- Zero indoor particulate matter during combustion
- Reduced pressure on Rwanda's forests and hillside ecosystems
- Near-closed carbon cycle via sugarcane molasses feedstock
- Risk: supply chain logistics still carry transport emissions
- Measurable reduction in respiratory illness risk for women and children
- Modernised cooking experience — cleaner, faster, controllable
- Digital financial inclusion through mobile payment integration
- Community engagement in retail distribution network
- Risk: abrupt disruption caused acute vulnerability for adopters

4. Comparative analysis — how Rwanda's case compares
KOKO Networks first deployed its ethanol fuel utility model in Kenya before expanding to Rwanda, making the Kenya experience an important reference point for understanding what happened in Kigali. In Nairobi, the system demonstrated greater resilience largely because it operated in a larger, more diversified market with a longer operational track record, deeper retail integration, and a more established financial base.
| Factor | KOKO Kenya (Nairobi) | KOKO Rwanda (Kigali) | Key difference |
|---|---|---|---|
| Market maturity | 2019 launch — 5+ years of operation | 2022 agreement — 3 years to disruption | Rwanda had less runway to stabilise |
| Market size | Nairobi: ~4.5M urban residents | Kigali: ~1.4M urban residents | Smaller base = thinner economics |
| Ethanol feedstock | Local Kenyan sugar industry | Partially imported / regional sourcing | Rwanda more supply chain exposed |
| Policy support | Moderate — market-led model | Strong — RDB partnership, $25M commitment | Rwanda had stronger govt. backing |
| Operational continuity (2026) | Active and expanding | Paused — users stranded | Rwanda disruption was country-specific |
| System redundancy | Growing informal ethanol reseller network | Minimal — almost entirely centralised | No fallback for Rwanda users |
Looking beyond KOKO, the clean cooking landscape in East Africa is evolving on multiple fronts. Ethiopia's BioLite and SolarAid deployments show how hybrid energy models — combining solar-electric and ethanol — provide a partial hedge against single-point fuel failures. In Tanzania, LPG has seen the fastest growth but faces a different constraint: import dependency and cylinder distribution bottlenecks in rural areas. Rwanda's own electricity utility, REG, is aggressively expanding the grid and rolling out electric cooking pilots, but urban grid access alone does not resolve the affordability challenge for low-income households in 2026.
5. TechStream Insight — what the data is really telling us
The KOKO Rwanda disruption is being read by many observers as a technology failure or a policy failure. We think both framings miss the real lesson.
The technology worked. Bioethanol combustion chemistry is sound. The environmental data is compelling. The user experience, by most accounts, was genuinely superior to charcoal. The policy intent — a $25M public-private clean cooking utility — was ambitious and well-aligned with Rwanda's development trajectory.
What failed was systems resilience design. The Teka Smart ecosystem was built for scale under stable conditions. It was not engineered for continuity under financial stress, supply chain disruption, or the kind of operational pivot that a startup-stage utility company faces in its third year in a new market. In systems engineering terms, it had high efficiency and low redundancy — a combination that performs brilliantly until the first significant shock, then fails completely.
The deeper data point here is one that the clean energy transition community tends to underweight: adoption success creates vulnerability. When a household fully transitions to a new fuel — decommissions their charcoal stove, builds routines around a new cooking system, perhaps even loses access to the informal charcoal networks they previously relied on — they have made themselves entirely dependent on the new system's continuity. The more successful KOKO's adoption was, the more severe the consequences of disruption.
This is not an argument against clean cooking transitions. It is an argument for designing them with resilience architecture built in from day one — distributed supply buffers, contingency fuel access, community-level stockpile models, or hybrid-fuel stoves that can operate on multiple energy sources. The ethanol-only model, while elegant, created a single point of failure at the household level that the broader system architecture did not adequately address.
The comparison that matters most: Rwanda's formal charcoal market, for all its environmental problems, has one characteristic that the Teka Smart system lacked — it is structurally decentralised. Hundreds of individual charcoal traders create natural redundancy. No single failure can halt supply citywide. Clean cooking transitions that do not account for this structural advantage of the systems they are replacing will always be fragile.
6. Challenges and limitations
| Challenge | Description | Severity | Addressable? |
|---|---|---|---|
| Single-source supply chain | Entire fuel supply dependent on one centralised logistics system — no distributed fallback | Critical | Yes — decentralised ethanol reseller networks |
| Financial sustainability at small scale | Per-unit economics require high adoption volume; small markets make unit economics fragile | Critical | Partially — blended finance, subsidies |
| User lock-in without safety net | Households that fully adopt cannot quickly revert; informal charcoal access erodes post-transition | High | Yes — hybrid stove design, buffer stock programmes |
| Ethanol feedstock dependency | Rwanda lacks large-scale domestic sugarcane industry; ethanol partially imported | Moderate | Yes — invest in local feedstock production |
| Digital infrastructure assumption | Pay-as-you-go model assumes mobile connectivity and financial account access | Moderate | Yes — offline payment options, agent networks |
| Upfront device cost for poorest households | Stove hardware cost remains a barrier for the lowest-income quintile | Moderate | Yes — lease models, cross-subsidy schemes |
7. Future outlook — what happens next for clean cooking in Rwanda
Despite the disruption, the case for clean cooking in Rwanda has not weakened — if anything, the KOKO pause has clarified what the next generation of clean cooking deployments needs to look like. Several trajectories are worth watching closely over the next 2–5 years.
Electric cooking as the long-term trajectory
Rwanda's electricity access rate has climbed significantly — from below 20% in 2010 to over 72% in 2023 across household connections, with Kigali near-fully electrified. The Rwanda Energy Group's (REG) ongoing grid expansion and the falling cost of induction cookers are creating conditions for electric cooking to become the realistic long-term default for urban households. The challenge remains affordability: a quality induction cooker still represents a significant upfront cost relative to median household income, and peak electricity demand management is an ongoing grid challenge.
Bioethanol's role — smaller but more resilient
Bioethanol is unlikely to disappear from Rwanda's clean cooking mix, but any future deployment model will need to be structured differently. The most viable path is a distributed model — multiple smaller ethanol producers feeding into a network of independent retailers, rather than a single centralised utility. This mirrors how LPG distribution works: multiple cylinder brands, multiple filling stations, multiple retail channels creating natural market redundancy.
The policy response
Rwanda's government has the institutional credibility and policy frameworks to course-correct. The National Energy Policy, updated NDC commitments, and an active RDB that has already demonstrated willingness to partner with private clean energy providers all point toward a re-engagement with the clean cooking sector — likely with more stringent supply chain resilience requirements built into future partnership agreements.
The KOKO Rwanda story is not finished. It is a chapter — and probably not the last one. The technology is sound. The policy will framework will be rebuilt. The market need has not gone away. What will be different in the next version of this story is what was missing in this one: resilience architecture, distributed supply, and a genuine answer to the question every clean cooking programme must ask — what do our users do when the system goes down?
A clean cooking transition that cannot survive its own operational disruption has not solved the problem. It has only deferred it.
