Ethiopia Slashes Bitcoin Miner Power to 23% of Contracted Levels as El Nino Strains Hydropower Grid
Ethiopia has cut electricity supplied to Bitcoin miners to 23 percent of contracted levels after a 20 percent drop in reservoir inflows strained the country’s hydropower-dependent grid, forcing the state utility to prioritize households and manufacturers over its most lucrative industrial customers.
Citing a Bloomberg report from September 15, the reductions came after El Nino intensified dry conditions across the East African nation. Ethiopian Electric Power CEO Ashebir Balcha said the utility initially lowered deliveries to miners to 75 percent of contracted amounts, then to 50 percent, before cutting to 23 percent. The company plans to reassess reservoir and electricity conditions in October, with further cuts possible if water levels do not improve. Ethiopia could also restrict electricity exports to neighboring countries if domestic supply comes under additional pressure.
A mining boom that outgrew the grid
The restrictions land on a customer segment that has become financially critical to the state power company. Bitcoin miners consumed almost one-third of Ethiopia’s electricity output and generated 35 percent of EEP’s revenue during the previous fiscal year, according to Bloomberg.
Ethiopia’s emergence as a mining destination was built almost entirely on cheap hydroelectricity. Low power costs attracted international operators looking to cut their biggest operating expense, and by October 2024 miners were consuming roughly 600 megawatts in a country with around 5,200 MW of installed generation capacity, most of it hydropower with wind and thermal making up the remainder. The country subsequently expanded generation around projects including the Grand Ethiopian Renaissance Dam while international miners deepened their presence.
Abu Dhabi-listed Phoenix Group, for example, increased its Ethiopian Bitcoin mining capacity to 132 MW in April 2025 after adding a 52 MW facility to existing operations. The scale of Ethiopia’s role showed up in Cambridge Bitcoin energy-mix research in August, when hydropower overtook natural gas as the largest reported electricity source for Bitcoin mining, a shift researcher Alexander Neumueller partly attributed to better survey coverage in hydro-rich markets such as Ethiopia.
Cuts arrive as mining economics deteriorate
The power restrictions compound an already difficult period for miners worldwide. Economist Saifedean Ammous, author of The Bitcoin Standard, argued in a September 15 post that global Bitcoin mining electricity consumption and capital expenditure may have already peaked in 2024-2025.
His math is stark: because the April 2024 halving cut the block subsidy from 6.25 BTC to 3.125 BTC, Bitcoin’s price would need to rise more than 18.92 percent annually just to keep the dollar value of newly mined supply growing, before accounting for dollar depreciation. Instead, Bitcoin has lost more than 35 percent over the past twelve months, trading near 75,758 USD as of Wednesday, down 0.69 percent over 24 hours.
“Given this decline in mining rewards, it would be expected that bitcoin mining would slow down, or even contract,” Ammous said. “Unless there is a major turnaround in this metric, this trend may continue indefinitely.” He framed the peak hypothesis as testable, noting that substantially higher transaction fees or a sustained recovery in mining electricity consumption above the prior high would invalidate it.
Revenue pressure was visible well before Ethiopia’s cuts. Miner revenue reached 1.086 billion USD in May, the highest monthly total since January, yet mining economics remained strained as hashprice fell nearly 18 percent in a month. By July, public miners had sold more than 32,000 BTC during the first quarter of 2026, exceeding combined sales for all of 2025, while hashprice fell into the high-20 USD range per petahash per day, below the roughly 35 USD breakeven estimated for older machines.
AI data centers offer the escape hatch
For miners holding Ethiopian power contracts, the cuts raise an uncomfortable question about stranded infrastructure. One answer increasingly favored across the industry is artificial intelligence. Mining operators already control power agreements, land, cooling systems and data center infrastructure that can be repurposed for AI and high-performance computing.
The transition has accelerated through 2026. Public Bitcoin miners had secured more than 70 billion USD in AI and HPC contracts by June, while selling more than 15,000 BTC from corporate treasuries and raising debt to finance data center expansion. Nine public miners spent 5.11 billion USD on capital assets during the first half of 2026 while directly reporting 341.2 million USD in AI and HPC revenue, according to an August Blocksbridge Consulting analysis, with second-quarter AI revenue of 205.8 million USD up 52 percent quarter over quarter.
CleanSpark illustrates the model: a 239 million USD net loss in its fiscal third quarter sits alongside a 20-year Georgia AI data center lease expected to generate 6.6 billion USD. VanEck data cited by Miner Weekly estimates publicly traded miners could need around 50 billion USD to build out planned AI infrastructure.
For Ethiopia specifically, the October reassessment will determine whether miners can ride out the dry season or whether the country’s hashrate share erodes at the exact moment falling Bitcoin prices and post-halving economics are already squeezing margins. With hydropower now the largest reported power source in Bitcoin mining, grid stress in a single East African nation has become a variable the global industry can no longer ignore.
ethiopia lured miners in with cheap hydro and now they are first in line for cuts. 23 percent of contracted power is basically a shutdown notice with extra steps
as someone with family in addis, households getting priority over miners is the right call. rigs can move to paraguay, people and factories cant
fair point but the utility signed multi year contracts knowing el nino cycles exist. the blame sits with the planners, not the miners who paid full price
hard to plan around el nino cycles getting angrier though. contracts were priced on decades of stable inflows and the climate quietly rewrote the terms
contracts or not, when reservoir inflows drop 20 percent physics wins the argument. real question is whether anyone had downtime compensation written in
compensation clause is the whole ballgame. those contracts were signed at full price with 600MW committed, if ethiopian electric power can just cut to 23 pct with no penalty then the paper was never worth anything
this is the whole ballgame. if the contracts had force majeure language for hydro shortfalls the miners priced the risk. if not, EEP owes penalties it probably cant pay
the curtailment clauses apparently do exist for hydro shortfalls, just nobody priced in a cut this deep. penalties likely waived under force majeure, thats the sting
75 then 50 then 23, that glide path tells you the october reassessment is gonna be ugly. anyone building data centers there is recalculating today
phoenix group alone has 132MW parked there. if the october reassessment says 23 percent again that gear is on a boat to paraguay
that 132MW of phoenix gear isnt going anywhere. hosting agreements run for years, they will eat the 23 percent and pray the october reassessment goes their way
132MW of phoenix gear sitting at 23 pct is a space heater investment right now. the october reassessment decides if that fleet ever spins back up
paraguay is basically maxed on new allocations too. realistic destinations are texas gas flare sites or just eating the downtime
paraguay is nearly maxed on new load agreements. that 132MW of phoenix gear is more likely sitting cold until the october reassessment than moving anywhere
agreed on the gear sitting cold. 132MW does not relocate on short notice, ethiopia was the cheap hydro play and paraguay is booked out
75% then 50% then 23%, that glidepath is brutal. anyone with machines in ethiopia is basically offline right now
600MW out of 5200 total and they still got slashed. cheap power isnt cheap if it evaporates every dry season
everyone dunking on EEP but a 20 percent reservoir drop with households on the line, the october reassessment cutting miners further is the correct outcome whether miners like it or not
600MW committed out of a 5200MW grid and still first on the chopping block. cheap hydro always has an asterisk, its called the dry season
For context, this is what El Nino droughts do to a grid that is almost all hydro. Households and factories first is the right call, even if it hurts mining revenue.
rip to everyone who relocated asics to addis last year lol
miners were 35 percent of EEP revenue last fiscal year and still got cut to 23 percent power. tells you how bad the el nino inflow numbers really are
35 percent of EEP revenue and first against the wall when inflows dip 20. being the best customer clearly buys zero priority
october reassessment could go either way, el nino forecasts still show below normal rains through q4. 23 percent might be the floor for a while
below normal rains forecast through q4 means the october reassessment cuts deeper, not recovers. anyone holding out for 75 percent power back is dreaming
