The Ruacana Power Station supplied 78.3% of Namibia’s locally generated electricity in December 2025, making it the country’s largest source of domestic power generation during the month, according to the Namibia Statistics Agency (NSA).
The NSA said Ruacana generated 167,547 MWh out of total local electricity production of 213,957 MWh during the review period.
Independent Power Producers accounted for 19.2% (41,016 MWh) of local generation, while the Omburu PV Solar Power Station contributed 2.3% (4,958 MWh). The Anixas 2 Diesel Power Station supplied 0.2% (436 MWh), while the Van Eck Power Station and Anixas 1 Diesel Power Station recorded no electricity generation.
Total electricity supplied to the domestic economy stood at 414,982 MWh in December 2025, of which local generation accounted for 51.6%, while imports made up the remaining 48.4% (201,024 MWh).
“The electricity import index declined by 12.9% month on month in December 2025, following an 11.5% decrease recorded in the previous month. On a year-on-year basis, however, the index increased by 7.0%. Namibia imported a total of 201,024 MWh of electricity in December 2025,” the NSA said.
The electricity sources composite index, which includes both local production and imports, increased by 7.7% during the month, recovering from an 8.2% decline recorded in November 2025. On a year-on-year basis, however, the index fell by 7.2%.
Electricity supplied to the domestic economy increased from 385,477 MWh recorded in November 2025 but remained below the 447,185 MWh supplied in December 2024.
“Local generation accounted for 51.6% (213,957 MWh) of the total electricity supplied to the domestic economy, while imports contributed 48.4% (201,024 MWh). This distribution represents a shift from November 2025, when imports constituted the dominant share of electricity supply, and mirrors the pattern observed in December 2024,” the NSA said.
The electricity sales composite index rose by 3.5% month on month in December 2025, reversing an 8.1% decline recorded in November. However, the index declined by 8.9% compared to the same period last year.
Electricity sales reached 347,374 MWh during the month, higher than the 335,539 MWh sold in November 2025 but below the 381,191 MWh recorded in December 2024.
Domestic electricity sales declined by 0.9% month on month and fell by 6.3% on a year-on-year basis. Total domestic power sales stood at 311,270 MWh, down from 314,092 MWh in November and lower than the 332,222 MWh recorded in December 2024.
Redistributors LPU accounted for the largest share of domestic electricity sales at 66.9%, followed by the mining industry at 24.6% and Eskom Orange River at 3.4%. Sales to farms represented 1.5% of domestic electricity consumption, while agriculture and irrigation and plots miscellaneous categories contributed 1.3% and 0.8% respectively.
The NSA said the electricity export sales index increased by 68.3% in December 2025, rebounding from a 41.2% decline recorded in November, although the index remained 26.3% lower on a year-on-year basis.
Namibia exported 36,104 MWh of electricity during the period, with 93.6% sold through STEM Sales. Botswana accounted for 3.4% of exports, while South Africa and Angola received 1.7% and 1.4% respectively.
