Global GridTanzania's energy mix and electricity
🇹🇿 In 2024, Tanzania generated 8.84 TWh of electricity. The largest source was gas at 63%, followed by hydro (32%) and oil and other fossil fuels (4.3%). In total, 33% came from low-carbon sources (nuclear and renewables) and 67% from fossil fuels.
On average, each kilowatt hour produced about 345 grams of carbon dioxide (CO₂), below the world average of 458 grams in 2025. That makes Tanzania the 72nd cleanest of 158 countries that generate at least 1 TWh a year.
Electricity demand was 9.03 TWh. Tanzania imported 0.19 TWh more electricity than it exported, equal to 2.1% of its demand.
Since 2000, electricity generation has grown by 254%, from 2.50 TWh. The low-carbon share went from 86% to 34%. The biggest rise was in gas, from 0% to 63% of generation. The biggest fall was in hydro, from 85% to 32%. Carbon intensity rose from 120 to 345 grams per kWh.

Energy security score
Moderate. Tanzania ranks 102nd of 158 countries and 19th of 35 in Africa. The score shows how well a country could keep electricity affordable and on if fuel supplies were disrupted. It is based on 4 of the 5 measures.
| Measure | Score |
|---|---|
| Produces its own energy No reliable figure exists for Tanzania, so this measure is left out and the other four count for more. | n/a |
| Variety of power sources How evenly generation is spread across nine sources. The largest, gas, made 63%. | 57 |
| Little reliance on imported power Net imports were 2.1% of demand; each 1% takes off 2 points. | 96 |
| Low-carbon power Nuclear and renewables made 33% of generation. | 33 |
| Low gas and oil use Gas and oil made 67% of generation; the score is 100 minus that share. | 33 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
Oil and gas pipelines
Global Energy Monitor lists 2,276 km of oil and gas pipelines operating in Tanzania, 1,452 km being built and 1,999 km proposed (lengths measured along the mapped routes; a pipeline crossing borders counts in full for each country). For liquefied natural gas (LNG), shipped by sea, it lists 0 export terminals operating (2 more being built or proposed).
