Ethiopia slashes power 75% to BTC miners

TLDR

Ethiopias state utility has sharply cut electricity to Bitcoin mining companies, reducing their supply by about 75% because hydropower output is under pressure.

1. Ethiopian Electric Power now delivers only about 23% of contracted power to mining and data firms after reservoir inflows dropped around 20 percent.
2. Miners had grown to nearly one third of national electricity use and 35% of the utilitys revenue, but households and factories are being prioritized.
3. Ethiopia contributes roughly 2.4% of global Bitcoin hashrate, so network impact is modest yet highlights climate and policy risk for hydro dependent mining hubs.

Deep Dive

1. What Ethiopia Has Done

Ethiopian Electric Power (EEP) has cut electricity to Bitcoin and other data mining companies by about 75%, leaving them with only 23% of their contracted supply, according to EEP leadership cited in recent reporting on the 75% power cut.

The move follows El Nio linked weather that reduced inflows into hydro reservoirs by around 20%, hitting a system where hydropower provides roughly 95% of national electricity. Contracts had promised miners at least 98% of agreed power, but EEP has progressively rationed them from 75%, to 50%, and now 23% of that contracted amount.

EEP plans to reassess allocations in October, framing the decision as a seasonal grid protection measure rather than a permanent ban on mining.

2. Impact On Ethiopian Miners

Bitcoin miners had become some of EEPs largest customers, consuming close to one third of Ethiopias electricity and generating around 35% of the utilitys revenue, with reported payments of about 50 billion birr last year from 39 companies, 31 of them operational.

Cheap hydro priced near 3.2 cents per kilowatt hour made Ethiopia attractive. One Bitcoin mined there is estimated to use around 6.4 million kWh, roughly the annual consumption of almost 15,000 households, so in a dry year mining is an obvious target when half the population still lacks grid access.

With power now cut to 23% of contracted volumes, many operations will be forced to curtail, pause, or consider relocating, and EEP has already lowered its forecast export revenue by about 40% as water constraints tighten.

3. Global Bitcoin Network Effect

Ethiopias mining sector is estimated to represent around 2.4% of global Bitcoin hashrate, roughly 23 exahash per second, so the direct impact on the Bitcoin network is limited in the short term.

If Ethiopian hashrate falls, Bitcoins difficulty adjustment will gradually rebalance block times, and other regions with more stable power will absorb some of the gap. However, the episode underscores a broader vulnerability for hydro heavy mining hubs where weather variability can abruptly change economics.

Over time, this kind of shock can shift where mining is profitable, influence which operators survive, and contribute to geographic rotation of hashrate, with implications for decentralization and energy mix debates.

Conclusion

Ethiopias 75% cut to miners power is a clear reminder that the cheap green hydro story for Bitcoin mining is constrained by real world water and grid politics. The immediate damage is concentrated in Ethiopian facilities, not the global network, but it exposes climate and contract risk that miners and investors need to factor into long term economics.

Confidence: high because multiple independent reports and utility statements align on the scale of the cuts and Ethiopias relatively small share of global hashrate.
