Ethiopian Electric Power has reduced electricity deliveries to Bitcoin miners to 23% of contracted supply after inflows to the country’s dams fell about 20%, tightening generation from a power system that relies overwhelmingly on hydropower. The utility had previously reduced miners’ allocations from 75% to 50%; their contracts stipulated a minimum 98% supply. EEP plans to reassess the restrictions in October and has warned that mining companies and electricity-export customers face further cuts if reservoir levels do not recover. Ethiopia has agreements with 39 mining companies, including 31 already operating. Miners consumed roughly one-third of national electricity while contributing about 35% of EEP revenue, largely through foreign-currency payments for low-cost power. The Grand Ethiopian Renaissance Dam generated 18.3 terawatt-hours last year, about 52% of Ethiopia’s electricity, underscoring the sector’s dependence on water availability. Ethiopia represents about 2.4% of global Bitcoin hashrate, limiting the likely effect on the wider network while raising operational risks for miners reliant on Ethiopian hydropower.
