Tanzania Has Connected 71 Percent of Households to Electricity. A New NBS Survey Shows Most Use Less Than TZS 10,000 of It Per Month. That Is Not an Energy Problem. It Is an Income Problem.

DAR ES SALAAM — Tanzania's electricity access rate has reached 71.2 percent of households, according to the NBS Household Energy Consumption Survey 2023, representing one of the fastest electrification trajectories on the continent. Fifteen years ago, fewer than one in five Tanzanian households had electricity. Today, more than seven in ten do. The achievement is genuine and consequential. The Julius Nyerere Hydropower Project's 2,115MW, the Rural Energy Agency's village electrification programme, and the TANESCO grid expansion that reached 100 percent of Tanzania's 12,318 villages by FY2024/25 are the investments that produced it. Their combined effect has been transformative at the infrastructure level. The same NBS survey contains a finding that the electrification headline tends to obscure. Among households connected to electricity, 72.5 percent spend less than TZS 10,000 per month. Only a small proportion report monthly electricity expenditure above TZS 50,000. At TZS 10,000 per month, a household is paying for approximately 30 to 40 kilowatt hours, enough to power lights for several hours each evening and charge mobile phones. It is not enough to run a refrigerator, operate electric irrigation, power an electric cooker continuously, or support the kind of productive machinery use whose economic returns justify the infrastructure investment. Access is not the same as use The distinction between electricity access and electricity consumption is more than a semantic one. It determines whether energy infrastructure investment generates the economic returns its financing requires. A power station that generates electricity nobody can afford to use extensively is infrastructure without a customer base. The Julius Nyerere Hydropower Project's 2,115MW, the TZS 350 billion that Tanzania's FY2026/27 budget allocated to continuing JNHPP and a further TZS 350 billion to hamlet electrification, are investments whose full economic return depends on households and businesses consuming the electricity being generated at volumes sufficient to justify the capital cost. When consumption remains confined to lighting and phone charging across the majority of connected households, the economic multiplier from generation investment is substantially lower than the infrastructure economics assume. Utilities recover less revenue per customer despite serving more customers. Appliance manufacturers face weak domestic demand. Consumer finance products for durable goods find limited addressable markets. Industrial investors evaluating manufacturing locations note that household electricity demand, a proxy for disposable income and consumer market depth, remains shallow. The purchasing power constraint The NBS survey data implies that Tanzania's electricity constraint has shifted from supply to demand, and that the demand constraint is primarily an income constraint rather than an awareness or access one. A Tanzanian household that has electricity but spends less than TZS 10,000 per month is not being irrational. It is managing limited income across multiple competing priorities. The household may want a refrigerator. The household cannot afford one, either outright or through consumer finance. The household may want an electric cooker. The fuel cost savings relative to charcoal or kerosene may be insufficient to justify the appliance cost given the household's income level. The household may benefit from electric irrigation. The pump, installation, and electricity cost may exceed what the agricultural income the farm generates can service. Each of these is an income problem wearing the appearance of an energy problem. Solving it requires interventions in the income dimension, manufacturing employment growth, agricultural productivity improvement, SME development, and formal sector wage growth, rather than primarily in the energy dimension of additional generation capacity. What measuring consumption rather than connections reveals The policy implication is a required shift in how Tanzania measures energy progress. Connection rates are the correct metric when the primary challenge is infrastructure access. Consumption metrics become the correct indicator when the primary challenge is productive use. Productive electricity consumption indicators would ask: how many households cook with electricity? How many small businesses operate electrically powered equipment? How many farmers use electric irrigation? How many schools and clinics maintain reliable electricity throughout the school and working day? These questions move the measurement from infrastructure to productivity, and from the Ministry of Energy's traditional KPIs to the economic development outcomes that energy investment is intended to enable. Tanzania's FY2026/27 National Development Plan targets per capita energy consumption rising from 170kWh to 256kWh in the plan year and toward 528kWh by 2030. Reaching 528kWh per capita requires Tanzanian households to approximately triple their electricity consumption from current levels. That tripling will not come from extending the grid further. It will come from the income growth whose generation is Vision 2050's central economic challenge.
