Namibia’s reliance on imported electricity remained high in October 2025, with local power generation accounting for just 37.8% of total supply, according to the Namibia Statistics Agency (NSA).
The NSA said electricity imports contributed 62.2%, or 260,959 MWh, of total power supplied to the domestic economy during the month, while local generation amounted to 158,743 MWh. This trend mirrors patterns observed in September 2025 and October 2024, when imports also made up the bulk of electricity supply.
Total electricity delivered to the domestic economy in October stood at 419,702 MWh, up from 401,058 MWh in October 2024 and 413,269 MWh in September 2025.
The Electricity Sources Composite Index, which measures both domestic generation and imports, rose by 1.6% month-on-month in October 2025 and increased by 4.6% year-on-year.
Of the electricity generated locally, the Ruacana Hydropower Station remained the leading contributor, supplying 70.6% or 112,031 MWh. Independent power producers accounted for 25.1%, or 39,794 MWh, while the Omburu PV Solar Power Station contributed 3.4%, equivalent to 5,394 MWh. The Anixas 2 Diesel Power Station supplied 0.8%, or 1,253 MWh, of total domestic output.
After declining by 2.5% in September 2025, the Electricity Import Index increased by 12.6% in October, although it declined by 3.5% on an annual basis.
South Africa remained Namibia’s main source of electricity imports, supplying 59.9% of total imported power. Zimbabwe contributed 16.1%, Zambia 14.3%, while Eskom Orange River and the Southern African Power Pool (Day Ahead Market) accounted for 5.5% and 4.2%, respectively.
Electricity sales declined slightly during the month. After increasing by 5.6% in September, the Electricity Sales Composite Index fell by 0.9% month-on-month in October 2025, although it rose by 9.0% year-on-year.
Electricity sales totalled 364,980 MWh in October 2025, higher than the 334,907 MWh recorded in October 2024 but marginally lower than the 368,193 MWh sold in September 2025.
The Domestic Electricity Sales Index increased by 5.9% month-on-month after a 3.5% decline in September, and rose by 0.6% year-on-year.
Redistributors Local Power Units accounted for 68.1% of domestic electricity sales, followed by the mining industry at 24.1% and Eskom Orange River at 3.4%. Farms (main supply) contributed 1.4%, while plots and miscellaneous users and agriculture and irrigation each accounted for 0.8%.
The NSA also reported a sharp decline in electricity exports. After rising by 112.5% in September 2025, the Electricity Export Sales Index fell by 37.2% in October, although it increased by 343.4% year-on-year.
Namibia exported 36,483 MWh of electricity during the period under review. Of this, 93.6% was sold through STEM or the Southern African Power Pool, while Botswana received 3.5%. Angola and South Africa each accounted for 1.5% of total exports.
