Understanding the Dry Season for Mining in China

Starting from September, Southwest China enters the dry season, meaning that the low price of hydropower in that region is no longer available until the rainy season next year. The dry season creates a tremendous impact on China’s mining landscape, even the world. Without the benefit of low electricity costs, miners in China are looking for ways to stay profitable and survive the dry season. Income depends on the revenue generated by the miner’s computing power and the cost of operating the miner.

Electricity Cost Management

Without the cheap hydropower, the more economical electricity resource is now the thermal power located in Inner Mongolia and Xinjiang. In order to carry out operations, some miners choose to move their miners to these areas. A smooth and successful migration depends on the following items:

Consistent and Reliable Power Supply

Apart from the competitive price, continuity of power supply should be a priority. In fact, in many areas of thermal power generation, the stability of the power supply has been an issue when mining farms cluster around power stations, sometimes causing instability.


Regulations can affect the power supplied to facilities and, some provinces in China may not be as supportive of mining. For example, although it carries the advantage of a low electricity price, the Inner Mongolian government controls the mining operation of the area. In late 2019, the Ministry of Industry and Information Technology in Inner Mongolia issued a notice to Inner Mongolia Power (Group) Co Ltd. Under the notice, some companies found to be engaged in mining operations would no longer be able to obtain favorable electricity prices through Inner Mongolia’s Multilateral Trading Market.


Reliability of the partner is also a key factor to consider. Before signing the contract, miners should consider the reputation, infrastructure and operation of the mining farm, as well as its compliance to avoid unexpected losses.

Change Miners Efficiency

The dry season brings challenges but also great opportunities. With the removal of older miner models, the overall hash rate of the network has decreased, as has the overall difficulty, leaving more space for new machines with higher hash rates to enter.

With that in mind, a solution of better performing machines is key to seizing the opportunity. Bitmain’s Antminer 19 series is strong proof of that. The Antminer S19 Pro features a hash rate of 110 TH / s and an impressive power efficiency of 29.5 ±% 5 J / TH. The Antminer S19 is equipped with a hash rate of 95 TH / s and a power efficiency of 34.5 ±% 5 J / TH. And once the series is out on the market, it was sold out immediately, Bitmain has introduced tens of thousands of Antminer 19 Series and has been continuously optimizing the supply chain.

The nearly six-month dry season has always been a challenge for miners in China, but at the same time, there are still plenty of opportunities. Bitmain continues to help customers discover and seize opportunities with more high quality products and services.
