Kazakhstan Loses Another 1.2 GW of Hashrate as Power Allocation Policy Sours

Kazakhstan, once the world's second-largest Bitcoin mining hub after China, has now lost an estimated 1.2 gigawatts of mining capacity to relocation over the last 90 days, according to data compiled by Cambridge's Centre for Alternative Finance. The latest exodus is driven primarily by a new national power tariff structure that became effective in January and substantially raised the cost of electricity for cryptocurrency mining operations.

The policy mechanics

The new tariff introduces a three-tier structure for industrial power consumers:

• Tier A (conventional industrial): 7.2 tenge/kWh
• Tier B (data centers, general): 12.4 tenge/kWh
• Tier C (cryptocurrency mining, explicitly categorized): 19.8 tenge/kWh

The Tier C rate is 175% above the conventional industrial rate and 60% above the general data center rate. The policy is explicit — mining is singled out for a higher rate based on its consumption profile.

"The framing that mining should subsidize the rest of the grid is a political framing, not an economic one." — a senior executive at one of the relocating operators, speaking on condition of anonymity

Where the hashrate is going

The displaced capacity is moving in three directions:

• Ethiopia: approximately 450 MW
• Paraguay: approximately 280 MW
• Oman: approximately 210 MW
• United States (primarily Texas and Wyoming): approximately 260 MW

The geographic diversification of the post-Kazakhstan hashrate is, on net, a security positive for the Bitcoin network. The concentration that Kazakhstan represented at its peak — approximately 18% of global hashrate — was a single-point-of-failure risk that the ecosystem has quietly appreciated reducing.

The Kazakh government's position

The government's framing of the policy is that mining imposes grid costs that the previous tariff structure did not capture. There is a defensible version of this argument. Mining load is continuous and inflexible, which does impose costs on grid operators different from the costs imposed by flexible industrial load. Whether those costs justify a 175% premium is a separate question.

The Kazakh finance ministry has also, less publicly, expressed concern about the tax revenue implications of having a large mining sector that is highly mobile. Mining income is not as readily taxable as fixed-industry income, because operations can relocate. The tariff structure may have been designed partly to shift the extraction from income taxation to energy pricing.

What happens to Kazakhstan's remaining operators

The hashrate that remains in Kazakhstan — approximately 3.4 GW at peak, now closer to 1.8 GW — is concentrated in operators with specific site-level power arrangements that are not affected by the new tariff. Those operators are running what is effectively a sheltered legacy fleet. Their competitive position is strong for as long as the arrangements hold. Whether the arrangements hold through the next policy cycle is a question the industry is watching.

The larger lesson

Kazakhstan's trajectory — from near-dominance to structural marginalization in under five years — is the most visible case study in the political economy of Bitcoin mining. The pattern is recognizable: initial welcome, rapid build-out, consumer-price impact, political backlash, policy change, exodus. The jurisdictions now absorbing the exodus should read the pattern with interest. It will, if history is a guide, repeat.
