Maputo households spend MZN 1,200-MZN 2,800 per month on charcoal, yet ethanol cookstove distributors struggle to prove cost parity because fuel supply chain data barely exists south of the Maputo Bay bridge. Carlos Nhamire distributes ethanol stoves and fuel canisters across KaTembe and Boane districts, serving 1,400 active households with a logistics chain that breaks down at the last-mile delivery stage. AskBiz closes the data gap between production-gate ethanol pricing and actual delivered cost per cooking hour that determines whether clean cooking can outcompete charcoal in peri-urban Mozambique.

What Does It Actually Cost to Cook Dinner in KaTembe?#
This is the question that nobody in Mozambique's clean cooking sector can answer with confidence, and it is the question that determines whether ethanol cookstoves will ever displace charcoal at scale. The problem is not that the data does not exist. It is that the data exists in fragments controlled by different actors who have no incentive to share it. Charcoal prices in Maputo's peri-urban markets fluctuate between MZN 80 and MZN 150 per sack depending on season, source district, and municipal enforcement activity against illegal charcoal transport. A typical household in KaTembe, the rapidly growing district south of Maputo Bay connected by the Maputo-KaTembe bridge completed in 2018, consumes 3-5 sacks of charcoal per month for cooking. That places monthly cooking fuel expenditure between MZN 240 and MZN 750 for charcoal alone, before accounting for the cost of the charcoal stove itself. But these numbers come from household surveys with small sample sizes, conducted by NGOs with varying methodologies, and they do not capture the full cost of charcoal cooking. They exclude the health costs of indoor air pollution, the time cost of purchasing and transporting charcoal from market to home, and the replacement cost of charcoal stoves that corrode and require replacement every 8-14 months. Carlos Nhamire has been distributing ethanol cookstoves in KaTembe since 2023, and his fundamental business challenge is that he cannot definitively prove to a customer that his product is cheaper than charcoal, because neither his costs nor the charcoal baseline are measured with sufficient granularity. The data gap is not academic. It is the primary barrier to customer conversion and, by extension, to investor confidence in the clean cooking distribution model.
Carlos Nhamire's Distribution Model: Stoves and Fuel Canisters#
Carlos operates a two-product distribution business from a small warehouse in KaTembe's Guachene neighbourhood. The first product is the ethanol cookstove itself, a pressurised canister-fed burner manufactured in South Africa and imported through Maputo port. Carlos purchases stoves at MZN 2,800 per unit from the manufacturer's Mozambican distributor and sells them to households at MZN 3,500 on cash purchase or MZN 4,200 on a 3-month instalment plan. His gross margin on stove sales is MZN 700-MZN 1,400 per unit depending on payment method. The second product is the ethanol fuel canister, a sealed 1.2-litre container of denatured bioethanol that slots into the stove and provides approximately 4-6 hours of cooking time depending on flame setting. Carlos purchases fuel canisters at MZN 65 each from a depot in Matola and sells them to households at MZN 95 each. His gross margin on fuel is MZN 30 per canister, or approximately 31.6%. A household cooking two meals per day typically consumes 5-7 canisters per week, generating recurring fuel revenue of MZN 475-MZN 665 per household per week. Carlos currently serves approximately 1,400 active households, defined as those purchasing fuel at least twice per month. His monthly fuel revenue is approximately MZN 2.8 million, with fuel gross margin of approximately MZN 882,000. Stove sales add MZN 120,000-MZN 180,000 in monthly gross margin depending on new customer acquisition. The business model depends entirely on fuel attachment: stove sales alone cannot sustain the operation. Carlos's break-even requires maintaining at least 1,100 active fuel-purchasing households, making customer retention the critical operational metric.
The Last-Mile Fuel Logistics Problem#
Carlos's single largest operational challenge is delivering ethanol canisters to 1,400 households scattered across KaTembe and Boane districts at a cost that preserves his MZN 30 per canister margin. His current logistics model uses three delivery routes operated by motorbike riders carrying insulated delivery boxes, each holding 40 canisters. A rider completes 15-22 delivery stops per route, covering 35-60 kilometres depending on the route. Each rider is paid MZN 650 per day plus MZN 8 per delivery stop, averaging MZN 790 per day. Fuel cost for each motorbike is MZN 180-MZN 240 per day depending on route distance. The all-in delivery cost per canister is MZN 11.50-MZN 16.80 depending on route density. On his densest route covering central KaTembe, delivery cost is MZN 11.50 per canister, leaving MZN 18.50 net margin. On his most dispersed route into southern Boane district, delivery cost rises to MZN 16.80, compressing net margin to MZN 13.20 per canister. The margin difference between his best and worst routes is 29%, yet Carlos operated for his first eight months without route-level cost data. He knew his aggregate monthly delivery expense and his aggregate fuel revenue, but he could not attribute costs to specific routes, specific riders, or specific customer clusters. He was effectively subsidising low-density rural deliveries with profits from dense urban clusters without knowing it. AskBiz's route costing module, which Carlos adopted in mid-2024, assigns every delivery to a route and calculates per-canister delivery cost by route by week. This visibility enabled Carlos to restructure his Boane route from daily to three-times-weekly delivery, consolidating drops and reducing per-canister delivery cost on that route from MZN 16.80 to MZN 13.40. The restructuring saved MZN 24,000 per month in delivery costs without losing a single active customer.

The Charcoal Price Data That Does Not Exist#
To prove ethanol cost parity with charcoal, Carlos needs reliable charcoal price data at the household level. This data does not exist in any systematic form for KaTembe or Boane districts. Mozambique's National Statistics Institute publishes quarterly consumer price indices that include a charcoal component, but the index covers Maputo city proper, not KaTembe. Charcoal prices in KaTembe are consistently 15-25% higher than Maputo city because of transport costs across the bay and lower vendor competition. The Global Alliance for Clean Cookstoves published household cooking fuel expenditure data for Mozambique in 2019, but the sample included only 180 households in Maputo province and the methodology aggregated all solid fuels including charcoal, firewood, and agricultural waste. Extracting a charcoal-specific per-cooking-hour cost is not possible from the published data. Carlos conducted his own household survey in early 2024, sampling 120 charcoal-using households in KaTembe. His findings showed monthly charcoal expenditure ranging from MZN 1,200 to MZN 2,800, with a median of MZN 1,850. Converting this to a per-cooking-hour cost requires assumptions about daily cooking hours that vary widely by household size and composition. Carlos estimated 3.5 cooking hours per day for a median household, yielding a charcoal cost of approximately MZN 17.60 per cooking hour. His ethanol cost per cooking hour, calculated from canister price divided by burn time, is MZN 15.80-MZN 23.75 depending on flame setting. At low-to-medium flame, ethanol approaches charcoal cost parity. At high flame, ethanol is 35% more expensive. The honest conclusion is that ethanol is cost-competitive for simmering and moderate cooking but more expensive for high-heat applications like grilling and deep frying. This nuanced reality does not fit neatly into investor pitch decks, which is precisely why the data gap matters.
What Investors Need That Carlos Cannot Yet Provide#
Carlos is seeking MZN 8 million in growth capital to expand from 1,400 to 4,000 active households over 18 months. He has approached two impact investors and the IFC's Lighting Global programme, which has expanded its mandate to include clean cooking. Every investor conversation reaches the same impasse: they want three data points that Carlos cannot provide with institutional confidence. The first is customer lifetime value measured in months of active fuel purchasing. Carlos has 22 months of operating history, but his customer tracking was manual for the first 10 months. He can demonstrate 12 months of AskBiz-tracked data showing an average customer lifespan of 8.4 months before churning, but investors question whether early-stage churn rates will hold as the customer base scales beyond early adopters. The second data point is fuel supply chain resilience. Carlos sources ethanol from a single depot in Matola, which itself sources from a sugar-ethanol refinery in Xinavane. If that refinery reduces ethanol output due to a poor sugarcane harvest or diverts ethanol to export markets, Carlos has no alternative supply. Investors want supply diversification evidence that does not exist because there is currently only one industrial-scale ethanol producer in southern Mozambique. The third data point is carbon credit revenue potential. Ethanol cookstoves displacing charcoal generate measurable CO2 reduction, and voluntary carbon markets could add MZN 8-MZN 15 per household per month in credit revenue. But monetising these credits requires metered usage data that Carlos's canister-based system captures imperfectly. He knows how many canisters each household purchases but not actual burn hours, which is the metric required for Gold Standard or Verra carbon credit methodologies. AskBiz captures the purchase data rigorously; the gap is in translating purchases to verified emissions reductions.
Closing the Clean Cooking Data Gap in Peri-Urban Mozambique#
The clean cooking sector in Mozambique has attracted approximately $12 million in combined grant and investment capital since 2020, yet market penetration of improved cookstoves remains below 8% of urban households and below 2% of rural households. The sector's persistent underperformance relative to investment is not a technology problem. The stoves work. It is not a demand problem. Households want cheaper, cleaner cooking fuel. It is a data problem that prevents investors from pricing risk, prevents distributors from optimising operations, and prevents policymakers from designing effective subsidies. Carlos's experience in KaTembe illustrates how AskBiz addresses this gap at the operational level. Before adopting the platform, he managed customer records in a notebook, delivery routes from memory, and financials in a spreadsheet updated weekly by his bookkeeper. His investor conversations consisted of anecdotes and estimates. Twelve months after adoption, he can produce auditable reports showing customer acquisition cost of MZN 380 per household, average monthly fuel revenue of MZN 2,000 per active customer, route-level delivery cost per canister, and 30-60-90 day customer activity status. This does not solve the macro data gaps around charcoal baseline pricing, ethanol supply diversification, or carbon credit verification. But it solves the micro data gap that prevents individual clean cooking enterprises from presenting institutional-quality financials to investors. The Mozambican government's National Clean Cooking Strategy targets 3 million households using improved cookstoves by 2030. Achieving that target requires deploying hundreds of distributors like Carlos across Maputo, Gaza, Inhambane, and Sofala provinces. Each of those distributors needs the same operational visibility that Carlos now has. AskBiz provides the data infrastructure layer that can standardise reporting across a fragmented sector, giving investors a common analytical framework to evaluate and compare clean cooking distribution businesses across southern Mozambique.
