Ethiopia Cuts Bitcoin Miners to 23% of Contracted Power

Ethiopia’s Bitcoin mining boom has run into the physical limit that matters most: available electricity.

Ethiopian Electric Power has reduced deliveries to data-mining companies to roughly 23% of their contracted supply as lower water inflows strain the country’s hydroelectric system. The decision puts households and manufacturers ahead of mining operations during a difficult dry period.

Cointelegraph said the state-owned utility first reduced mining deliveries to 75% of contracted levels, then 50%, before cutting them to 23%, while reservoir inflows ran about 20% below normal. The report also said miners consume close to one-third of Ethiopia’s electricity production, supplied about 35% of the utility’s revenue in the last fiscal year, and now sit behind households and manufacturers in the rationing order.

The size of the cut is striking because miners have become one of the utility’s most important customer groups. Bitcoin mining companies consume close to one-third of Ethiopia’s electricity production and produced roughly 35% of Ethiopian Electric Power’s revenue in the last fiscal year, according to the report.

That makes this more than a routine curtailment. Ethiopia attracted miners with abundant, inexpensive hydropower and the promise of large contracted loads.

The same operators are now learning that a low-cost power agreement cannot guarantee electricity when a national grid has to ration scarce generation.

Africa Bitcoin News summarized the immediate cause and the effect on the country’s mining industry:

The wider debate now includes what slower mining growth could mean for Bitcoin’s long-term economics:

The disruption is already visible at the operator level. Epic Mining says its Ethiopian facilities are operating under energy restrictions tied to the dry season and confirms that available capacity was reduced to approximately 23% of contracted load.

Ethiopia has power-purchase agreements with 39 mining companies, with 31 reported to be operating. That concentration means the curtailment can force a meaningful amount of computing power offline or push operators to relocate equipment.

It does not, by itself, threaten Bitcoin’s global network. The protocol can adjust mining difficulty as total hash rate changes.

The more lasting issue is what this episode says about hydro-dependent mining. Hydropower can be cheap and relatively low-carbon, but it is vulnerable to weather.

A miner that relies on one state grid is exposed to rainfall, reservoir levels and the utility’s obligation to serve homes and strategic industries first.

Ethiopian Electric Power is expected to reassess the allocation in October. A recovery in water inflows could restore some of the missing load.

If conditions remain dry, miners may face longer restrictions and a difficult choice between waiting, moving machines or finding more expensive independent power.
