China Is the World's Largest Electricity Producer — So Why Can't That Power Be Used to Mine Bitcoin?

I realized I never truly understood "electricity."

During the May Day holiday, I drove myself through the Hexi Corridor — from Wuwei to Zhangye, Jiuquan, and then Dunhuang. On the highway cutting through the Gobi Desert, enormous wind turbines lined both sides of the road, standing like a wall of modern technology rising out of the raw wilderness.

A thousand years ago, the Great Wall was the symbol of frontier defense. Today, those endless rows of wind turbines and solar panels are guarding national energy security — the lifeblood of the next generation of industry. Sunlight and wind have never been harnessed and mobilized with this level of strategic intent — becoming part of a nation's sovereign capability.

In the Web3 industry, mining is core infrastructure — the background noise behind every bull run and on-chain boom. When people talk about mining, the conversation almost always comes back to two things: miner efficiency and electricity costs. Is mining profitable? Is power cheap? Where can you find the cheapest electricity?

But standing there watching that "electricity corridor" stretch endlessly across the desert, I realized I never actually understood electricity:

• Where does electricity come from?
• Who has the right to generate it?
• How do you transmit power from a desert to a city thousands of kilometers away?
• Who sets the price, and who controls consumption rights?

These are gaps in my understanding — and you might have the same questions. This piece is an attempt to systematically map out how electricity works in China: from generation mechanics and grid structure, to power trading frameworks and the regulatory barriers that make using that electricity to mine Bitcoin impossible.

How Much Electricity Does China Actually Produce?

According to Q1 2025 data from China's National Energy Administration, total electricity output in 2024 reached 9.4181 trillion kWh — up 4.6% year-over-year — accounting for roughly one-third of global electricity production. For context: the entire European Union generates less than 70% of that figure.

China isn't just producing more electricity — the generation mix has shifted dramatically.

By the end of 2024:

• Total installed capacity nationwide reached 3.53 billion kW, up 14.6%.
• Newly installed solar capacity hit 140 million kW; wind added 77 million kW.
• China alone accounted for 52% of new global solar capacity and 41% of new global wind capacity installed in 2024.

China leads the world in renewable energy generation, particularly across the Western and Northwestern regions — Gansu, Xinjiang, Ningxia, Qinghai — which are rapidly becoming the country's "new energy heartland." The country is rolling out mega-projects in desert and arid zones with a combined capacity exceeding 400 million kW, of which 120 million kW was already included in the 14th Five-Year Plan.

That said, coal hasn't disappeared — it has shifted into a backup and load-balancing role.

👉 The short version:

China doesn't have a shortage of electricity — it has a shortage of "flexible electricity," "consumable electricity," and "electricity that can be sold profitably."

Who Can Generate Electricity?

In China, power generation is not a fully open market. It is a regulated industry requiring a power generation license from the National Energy Administration, along with a lengthy list of prerequisites:

• Alignment with national and local energy planning.
• Completed environmental, land use, and safety assessments.
• Grid connection conditions met and consumption capacity confirmed.
• Technology up to standard, financing secured, safe implementation guaranteed.

Power generators in China fall into three main categories:

1. The five major state-owned conglomerates — including China Energy Investment, Huaneng, Datang, and others — control over 60% of coal-fired capacity and are aggressively expanding into wind and solar.
2. Local state-owned enterprises — such as Three Gorges, Jing Neng, and Shentou — operating in close coordination with provincial governments.
3. Private and mixed-ownership enterprises — including Longi, Sungrow, Tongwei, and Trina Solar — primarily active in solar, storage, and distributed generation.

Even if you're a top-tier company, you can't just decide to build a power plant and build one. There are three major chokepoints:

• Project quotas: your project must be included in the local energy plan and receive an allocated "quota."
• Grid connection: if the local substation is at capacity or transmission lines don't exist, a completed plant goes nowhere.
• Consumption capacity: if there are no buyers for the power, or no inter-provincial transmission lines, the electricity generated goes to waste — what the Chinese call "curtailed wind" and "curtailed solar."

This means generation capacity isn't just a function of capital and technology — it depends on planning approvals, policy alignment, and cross-regional coordination capacity.

How Is Electricity Transmitted?

China has a well-known structural paradox:
"Resources are in the West — demand is in the East — power gets generated but can't get transmitted."

The solution? Building an Ultra-High Voltage (UHV) transmission network — effectively a highway system for electricity.

By the end of 2024, China had commissioned 38 UHV lines, including some stretching over 3,000 km, such as:

• The Qinghai–Henan line (1,587 km).
• The Zhangbei–Gutuan line (3,293 km — a world record).
• The Northern Shaanxi–Wuhan line (660 billion kWh per year).

These lines are national-level projects, financed by State Grid Corporation or China Southern Power Grid and approved by the National Development and Reform Commission. Total investment typically exceeds 20 billion RMB per line, with construction timelines of 2–4 years and extensive environmental review, land acquisition, and cross-provincial coordination requirements.

UHV infrastructure remains firmly in the "national project" category — it is not something private enterprises can build independently.

How Is Electricity Sold?

The old model was simple:
Power plant → sells to national grid → end users → pay a fixed tariff.

But with renewables (near-zero marginal cost, variable output), a fixed-price model no longer works. Starting in 2025, China eliminated fixed pricing for new energy projects, requiring them to participate in open electricity markets, which include:

• Medium- and long-term contracts: essentially "pre-booked power," with prices locked in by agreement.
• Spot market: prices update every 15 minutes based on real-time supply and demand.
• Ancillary services market: selling frequency regulation, voltage support, and similar grid services.
• Green Energy Certificate (GEC) market: allowing consumers to purchase verified "clean" electricity.
• Carbon market: low-emission projects can sell carbon credits.

As an example: during summer 2024 in Guangdong, spot prices swung between 0.12 RMB and 1.21 RMB per kWh. Anyone with battery storage could buy cheap and sell high — and profit handsomely.

But if you're locked into a long-term contract or face consumption restrictions, you may end up forced to sell electricity at rock-bottom prices — or even zero.

So Why Can't This Power Be Used to Mine Bitcoin?

The short answer: infrastructure and policy both say no.

1. Bitcoin mining has been banned in China since 2021.
   Regardless of any power surplus, you cannot legally build a mining operation or purchase electricity from the national grid for that purpose.
2. Power projects require licenses, and illegal mining is easy to trace.
   Any large-scale mining operation will be flagged through utility billing data, power consumption records, and network traffic signatures.
3. Electricity consumption capacity is already pre-allocated by planning, with priority given to strategic industries, licensed data centers, and green development zones.
