Has the Electric Power Market Changed? Shandong Has Lowered the Minimum Electricity Price Limit – Will Ordinary People’s Bills Rise?
Hello everyone, I’m your financial journalist. Today we’re talking about a topic that may sound very technical, but it actually affects every single person and business: the electric power spot market is accelerating its implementation, and Shandong has just taken a significant step by lowering the “floor” of electricity prices.
Many non-experts, upon hearing terms like “negative electricity prices,” “spot market,” and “clearing prices,” might wonder, “What does this have to do with me? Don’t I just pay my electricity bill according to a fixed rate?”
Don’t worry; I’ll break down this news in simple language so you can understand it clearly. Let’s start with the conclusion and then discuss the logic behind it in five aspects.
Summary of the Key Points
In short, electricity is no longer just a simple transaction based on “how much is produced and how much is consumed.” It has become a large market that focuses on “timing” and “price.”
Currently, electricity spot markets are officially operating in nine provinces across the country (Anhui and Hebei have just joined). As a major province for renewable energy, Shandong produces more electricity than it can use, especially from solar and wind power, especially during the day and at night, which often results in prices dropping into the negative range (meaning the utility has to pay to generate the electricity).
To address this surplus of electricity, Shandong plans to further lower the minimum price limit. This means:
1. Power generation companies (especially those using solar and wind energy) need to learn to operate more efficiently, considering factors like the time of day, and may even need to invest in energy storage systems.
2. Coal-fired power plants may face tougher times because their costs are difficult to reduce, while the price cap has been lowered.
3. The energy storage industry (battery manufacturers and power stations) is seeing significant opportunities, as greater price fluctuations create more room for profit through buying electricity cheaply and selling it at a higher price.
4. For us ordinary consumers, residential electricity usage is generally not affected, and most commercial and industrial users’ electricity bills are fixed, so there’s no need to worry about sudden increases in bills.
Let’s delve into these points in more detail.

1. Why Do Negative Electricity Prices Occur? Does That Mean Power Generators Have to Pay to Produce Electricity?
Many people find it hard to grasp the concept of negative electricity prices. After all, electricity is a valuable resource. But it’s similar to a market situation where, if there’s a surplus of cucumbers and few buyers, the seller might offer them for free or even pay you to take them away to avoid waste.
In the electric power market, “negative electricity prices” occur when there’s more electricity generated than can be consumed immediately. This is because electricity cannot be stored (or storing it is very expensive), so it must be used immediately. For example, during the day when solar panels are producing a lot of electricity, but few people are using it, the grid must buy it to prevent overloading.
- The reason is simple: Electricity cannot be stored, and generating it during these times is not profitable (or even costs money). By setting the price low or even negative, power generators ensure their electricity is sold to the grid, even if it results in a small loss.
- This happens at the wholesale level (where power plants sell electricity to the grid or large users) and does not affect the price you see on your meter.

2. Why Does Shandong Want to Lower the Price Limit? To Promote Efficiency
Shandong plans to reduce the price limit from -0.08 yuan per kilowatt-hour to -0.12 yuan per kilowatt-hour. This might seem like a price cut, but it’s actually about letting the market determine the best use of resources.
Previously, a higher price limit meant that all power generators, regardless of their cost, could compete at the same low rate. This discouraged the use of cheaper renewable energy sources. By lowering the limit, Shandong aims to:
- Highlight the cost advantage of renewable energy: If a renewable energy source can generate electricity more cheaply, it should do so; otherwise, it should give way to cheaper alternatives.
- This encourages more efficient use of resources: It forces power generators to plan their production more carefully and encourages the development of energy storage systems.

3. Who Is Affected, and Who Is Benefiting? The Differentiated Fates of the Three Main Players
With the change in the price mechanism, the distribution of the electric power industry’s benefits will shift. We can categorize the players into three main groups: coal-fired power, renewable energy (solar and wind), and energy storage:
1. Coal-Fired Power: Under Pressure
- Current Situation: Coal-fired power generation costs are influenced by coal prices. With rising coal prices, coal-fired power is becoming less profitable.
- Challenges: With the lower price limit, coal-fired power plants may face losses if they continue to operate at full capacity.
- Impact: This could lead to a shift in their role from a major source of power to a secondary regulator, only coming online during peak times or when renewable energy is insufficient.
2. Renewable Energy (Solar/Wind): A Clear Divide Between Winners and Losers
- Benefits: The cost advantage of renewable energy is now fully utilized, allowing them to compete more effectively in the market.
- Challenges: They need to plan carefully, predicting when to generate electricity and how to store excess energy.
- Requirements: They must invest in energy storage or sign long-term contracts to lock in prices and reduce risk.
- Impact: This will drive the development of the energy storage industry and require more strategic planning for power generation.
3. Energy Storage: The Biggest Winner
- Logic: Energy storage becomes crucial as it allows electricity to be stored cheaply during off-peak times and sold at a higher price during peak times.
- Impact: The lower price limit increases the profit potential for energy storage companies, which could become essential components of the electric power system.

4. The Impact on Ordinary Users: No Need to Worry About Rising Bills
This is the most concerning question for many people: Will my electricity bill rise? The answer is generally no, and it might even become more stable.
1. Residential Users: Electricity prices for residents and agriculture are set by the government and are not affected by the spot market.
2. Commercial and Industrial Users: Although they participate in market transactions to some extent, most of their electricity usage is covered by long-term contracts.
- Impact: Even if spot prices fluctuate, it won’t significantly affect their overall bills.
5. Future Trends: Moving From Provincial Isolation to a National Market
The establishment of spot markets in provinces like Shandong and others is just the beginning. The future focus will be on connecting these markets across regions:
- Inter-provincial Integration: As markets mature, electricity can flow more freely between provinces, optimizing resource allocation and reducing waste.
- Benefits: This will lead to more efficient use of electricity and lower overall costs for society.

Conclusion
Shandong’s decision to lower the electricity price limit is a significant step in China’s electric power market reform. It marks a shift from a planned economy to a market-driven system. This change will:
- Transform the role of coal-fired power from a primary source to a regulator.
- Advance renewable energy by making it more competitive and efficient.
- Boost the energy storage industry as a key component of the electric power system.
This transformation will make electricity more accessible and efficient, just like water and air—always available and managed with intelligence.
