The following is an analysis report on the electricity price sensitivity of aluminum plate plants based on the current electricity price policy and the characteristics of the electrolytic aluminum industry, focusing on the impact of electricity cost changes on production costs and competitiveness:
1. The core position of electricity price costs in electrolytic aluminum production
Cost ratio
Electricity costs account for 30%-40% of the total cost of electrolytic aluminum production, which is the largest single cost item; the average electricity consumption for producing 1 ton of electrolytic aluminum is 13,500 kWh.
For every increase of 0.01 yuan/kWh in electricity prices, the cost per ton of aluminum increases by about 135 yuan (calculated based on average electricity consumption).
2. Analysis of sensitive points of electricity price policy
Tiered electricity price increase mechanism
2025 grading standard: The comprehensive electricity consumption threshold of aluminum liquid is reduced to 13,300 kWh/ton (excluding desulfurization electricity consumption).
Overconsumption penalty: For every 20 kWh above the threshold, the electricity price will be increased by 0.01 yuan/kWh, calculated progressively.
Sensitivity example: If a plant's electricity consumption is 13,500 kWh/ton (over 200 kWh), it will need to increase the price by 0.10 yuan/kWh, and the cost will increase by 1,350 yuan/ton.
Renewable energy deduction policy
When the proportion of non-hydro renewable energy consumption exceeds 15% and reaches the provincial incentive value, the step-by-step price increase standard will be reduced by 1% for every 1 percentage point increase.
If the proportion of green electricity in an enterprise reaches 20%, it can offset the 5% price increase, significantly alleviating cost pressure.
3. Impact of electricity price fluctuations on the profitability of aluminum sheet plants
Electricity price fluctuations Impact on the cost per ton of aluminum (yuan) Impact on gross profit margin (assuming aluminum price is 20,000 yuan/ton)
+0.05 yuan/kWh +675 Compressed by 3.38 percentage points
+0.10 yuan/kWh +1,350 Compressed by 6.75 percentage points
4. Risk warning and response strategies
Policy risks
In 2025, the step-by-step electricity consumption standard will be reduced by another 150 kWh/ton, and the cost pressure of enterprises that fail to meet the standard will increase.
After the electricity price of some aluminum plants in Sichuan was raised, the cost surged by 36% (case: Aba Aluminum Plant).
Corporate response measures
Energy efficiency upgrade: Keeping electricity consumption below 13,000 kWh/ton can avoid step-by-step price increases.
Green electricity transformation: Increase the proportion of wind power/photovoltaic power consumption to more than 20% and reduce the base for price increases.
Regional transfer: Layout production capacity in low-electricity price regions such as Xinjiang and Yunnan (the cost of hydropower in Yunnan is 0.3 yuan/kWh).
5. Conclusion
The profitability of aluminum sheet mills is polarized in terms of sensitivity to electricity prices:
Low-cost regions (Xinjiang/Yunnan): Strong tolerance to electricity price fluctuations, gross profit margin ≥ 25%;
High-cost regions (Henan/Sichuan): For every 10% increase in electricity prices, gross profit margin erosion exceeds 6%, and risks need to be hedged through technology upgrades or capacity replacement
