Zambia’s power crisis continues despite stable tariff

Zambia continues to face power shortages linked to low water levels at the Kariba Dam, though the energy regulator says electricity tariffs have not increased recently.

The Energy Regulation Board (ERB) confirmed that tariffs have remained unchanged since November 2025. Higher electricity bills reported by consumers reflect increased usage, not tariff adjustments, according to the board.

State utility ZESCO has applied to the ERB for a 30% tariff hike by July 2026 to remain cost-effective. No decision has been announced.

Zambia relies on hydropower for 80-90% of its electricity. A severe drought reduced Kariba Dam’s water levels to just 13% of usable storage in 2024, forcing extended power cuts. Some areas experienced outages lasting up to 17 hours per day.

The mining sector, Zambia’s economic backbone, has been hit hard. ZESCO has a power deficit of up to 250 megawatts, partly due to rising demand from copper mines. Mines face power curtailments of up to 40%, forcing some to import costly backup generation.

The government is investing in alternatives. In April and May 2026, authorities commissioned a 136 MW solar plant and launched a 250 MW solar project with battery storage. A $246 million deal for another 250 MW solar plant was also signed.

Industry officials say long-term solutions require sustained investment to diversify away from hydropower.
