Summary of Key Points
The energy storage market in Inner Mongolia continues to expand rapidly, but the development logic has shifted from an extensive model focused on securing quotas and achieving scale to a value-based competition that emphasizes technology, operational efficiency, and quality. This is evident in several aspects: there is an ample reserve of capacity (with 54 GWh of new projects added in the first half of the year), a diversification of participants (leading equipment manufacturers entering the market, disrupting the old landscape), EPC (Engineering, Procurement, and Construction) prices having dropped to record lows (narrowing profit margins), and a shift in profit models from relying on subsidies to generating revenue through market-based activities such as spot trading and providing ancillary services.
1. Rapid Expansion in Scale: Leading the Nation
The energy storage capacity in Inner Mongolia is still growing significantly. In the first half of 2026, the autonomous region announced two batches of projects totaling 54.8 GWh, accounting for 70% of the annual total from the previous year. Including projects that have only been registered, the total investment for the first half of the year reached 50.6 billion yuan, which is far ahead of any other province in China.
The distribution of projects is widespread, with all 12 leagues and cities having projects involved. Alxa, Hohhot, and Hulunbuir account for nearly 40% of the total capacity, making them key areas for development. This large number of projects indicates that Inner Mongolia remains an attractive destination for energy storage companies, but the approach to market entry has changed.
2. Competition Between New and Old Players: From Monopoly to Diversified Competition
Previously, the energy storage market in Inner Mongolia was dominated by a few new energy developers, such as Envision Energy and MingYang Smart Energy, which held 74% of the market share through early access to quotas. However, in 2026, new players entered the scene, including industry giants like CATL (battery manufacturer) and Haibo Sichuang (energy storage system provider). These companies bring their own technological advantages, such as self-developed battery cells and energy storage systems, and have established a complete ecosystem that encompasses equipment manufacturing, power station construction, and operation. They are competing on the basis of cost and technical expertise.
The market has moved beyond the era where the first to register a project would win; now, it is a comprehensive competition involving capital, resources, technology, and operational capabilities.
3. EPC Prices at Record Low Levels
The price of EPC services in Inner Mongolia has dropped to 0.6-0.7 yuan/Wh this year, which is 32% lower than the national average. Even more strikingly, the difference between the total EPC cost and the cost of energy storage systems is only 0.05 yuan/Wh, meaning that contractors have little profit margin left.
The reasons for these low prices are intense competition and rising costs of raw materials upstream, which have increased equipment costs without a corresponding increase in EPC prices. This indicates that the traditional model of securing projects at low prices and profiting from price differences in equipment has become ineffective. The focus now is on whether companies can complete projects at even lower costs.
4. Transformation of Profit Models: Fewer Subsidies, but Greater Revenue Opportunities
This year, energy storage subsidies in Inner Mongolia have been reduced by 20% (from 0.35 yuan/kWh to 0.28 yuan/kWh), and there are restrictions on the number of charge-discharge cycles per day (up to 1.5 times). However, this does not mean that profits have disappeared:
- Subsidies Still Play a Crucial Role: Although reduced, the ten-year compensation period provides stable cash flow, reducing financing difficulties for projects.
- Increased Opportunities for Spot Trading: The large price differences between peak and off-peak electricity prices in the western region of Inner Mongolia (up to 1.5 yuan/kWh) allow energy storage stations to buy electricity at low times and sell it at high times, generating profits from price variations.
- Ancillary Services Generate Revenue: Energy storage systems are used for frequency regulation services to help stabilize the power grid, and even with reduced subsidies, well-managed stations can still earn significant income.
In summary, the reliance on subsidies is declining, while the importance of market-based revenue is increasing. Energy storage is no longer a project that depends solely on government support; it has become an essential infrastructure component for the power grid.
Conclusion: From Scale Competition to Value-Based Competition
While Inner Mongolia's energy storage market continues to expand, the era of aggressive expansion is over. The focus has shifted to whether companies can build projects at lower costs, operate more efficiently, and establish a foothold through technological advantages. This marks the maturity of the energy storage industry—no longer relying on government subsidies but on its own value to sustain growth.
