Text by Xiao Li Fei Dao

Since early March, oil prices have surpassed $100 per barrel, and discussions about “new energy replacement” have increased. Leading energy storage companies like Sunshine Power and CATL have surged over 20% against the trend.

So, can the energy storage market continue to explode beyond expectations?

【How Hot Is Energy Storage?】

By the first half of 2025, the global energy storage market was still overshadowed by overcapacity, with companies across the supply chain engaged in price wars.

However, starting in the second half, the situation suddenly reversed—whether it’s cathode and anode materials, electrolytes, or battery cell companies, capacity utilization rates soared, reaching full capacity one after another.

The reason is simple: demand for energy storage has exploded.

According to ICC Xinluo, in 2025, global energy storage battery shipments will reach 640 GWh, an increase of 82.9% year-over-year. Among them, domestic battery manufacturers shipped 621.5 GWh, up 82.8%, while overseas manufacturers shipped 18.5 GWh, up 85%.

So, why did energy storage demand suddenly surge?

On one hand, the pressure to absorb new energy electricity is becoming increasingly prominent. Since 2025, spot prices for photovoltaic power have continued to decline, even dropping below one dime per kWh during peak generation times. This indicates that the absorption of new energy power has become a real challenge, making energy storage more necessary.

At the same time, as the peak-to-valley electricity price gap widens, energy storage stations become more economical by charging during low-price periods and discharging during high-price periods.

On the other hand, energy storage has crossed the economic inflection point—earning per kWh has begun to exceed costs.

In early 2025, the National Development and Reform Commission issued Document No. 136, explicitly canceling the “mandatory storage” requirement and promoting energy storage as an independent market participant. This shifted the development motivation from “policy-driven” to “market-driven,” igniting demand.

Following this policy direction, regions like Inner Mongolia and Ningxia introduced detailed policies, announcing capacity-based electricity price subsidies, further increasing project returns. It is estimated that investing in energy storage projects in Inner Mongolia can achieve an internal rate of return (IRR) of over 10%, even 15-20%. Such high returns naturally drove explosive growth in energy storage installations in Inner Mongolia.

More critically, the global energy storage boom is not a fleeting phenomenon.

【The Year of “Quantity and Price Rise”】

Currently, energy storage seems to be on the cusp of the photovoltaic boom of 2020.

From a valuation perspective, 2026 is likely to become the true year when both volume and price of energy storage rise together.

In September 2025, the National Development and Reform Commission and the National Energy Administration jointly issued policies stating that by 2027, the nationwide new energy storage installed capacity will reach over 180 GW. This means that in the next two and a half years, the installed capacity will nearly double.

However, based on the historical experience of industries like new energy vehicles, actual growth often exceeds plans. Some institutions predict that the probability of doubling domestic energy storage capacity in 2026 is quite high.

With policy guidance, detailed local regulations on energy storage will be rolled out gradually. Large-scale project tenders that are still vague in 2025 will become clearer by 2026.

The 2025 energy storage explosion is mainly driven by some provinces; demand in more regions will be released next year, further boosting installed capacity. Even Inner Mongolia, which has taken the lead, is expected to see demand double in 2026.

On one hand, the duration of energy storage deployment is increasing significantly. Early projects typically had two-hour durations, but now new projects generally require four hours or longer. Even if the installed capacity remains unchanged, the corresponding energy storage scale will double.

On the other hand, supportive policies for energy storage are becoming more sustainable.

Take Inner Mongolia as an example: its subsidies are not borne by the grid or local government but are shared by the renewable energy generation side. With excellent sunlight conditions locally, the power generation side can fully bear this cost, providing a sustainable basis for high-yield models.

The overseas market will also explode in 2026.

In fact, the combination of “photovoltaic + energy storage” is highly cost-effective overseas. The high costs of coal and natural gas power generation, coupled with the expensive investment in large transmission networks, make the solar-plus-storage solution particularly advantageous, driving high growth in overseas energy storage demand. Currently, geopolitical tensions in the Middle East have caused energy prices to surge, further accelerating this trend.

Sunnypower’s overseas strategy also reflects this trend. The company believes that the global energy storage market will grow by 40-50% in 2026, and its current strategy is “select the best.” This means abundant orders and the ability to maintain high profit margins.

In addition to installed capacity, prices along the energy storage industry chain are also expected to enter an upward cycle.

Before reaching full capacity in recent months, the industry experienced a long period of overcapacity and low prices, with many high-cost capacities pushed out of the market. The remaining players are mostly still in a replenishment phase, with no large-scale expansion unlike the rapid growth during the photovoltaic boom in 2020.

This suggests that 2026 could be the most tense year for supply and demand in the energy storage industry chain. Upstream materials like lithium carbonate, midstream battery cells, and downstream system integration may all see cyclical price increases.

It is also worth noting that in late November 2025, the Ministry of Industry and Information Technology held a meeting on anti-competition among power and energy storage battery companies. The sustained oversupply caused by the epic expansion of photovoltaics in the past is unlikely to recur in the energy storage sector.

Generally, “volume and price rise together” is one of the best phases for investing in cyclical stocks. Although the capital market still has differing opinions, the logic is—when energy storage shifts from a “cost item” in a power station to a “profit item” generating over 10% returns, the massive demand for installations will become inevitable.

【Who Will Be the Major Winners of the Cycle?】

The global energy storage boom is unstoppable. Who will be the big winners in this cycle?

From the profit distribution along the industry chain, downstream energy storage system integrators hold a higher profit share and are among the biggest beneficiaries.

Currently, leading A-share energy storage system integrators include Sunshine Power and Haibo Sichen. The former focuses on overseas markets, while the latter is deeply rooted domestically. Their financial reports clearly reflect the high prosperity of the energy storage industry.

In the first three quarters of 2025, Sunshine Power’s energy storage revenue reached 28.8 billion yuan, up 105% year-over-year. Its energy storage shipments increased by 70%, with overseas shipments rising from 63% last year to 83%. As an industry leader, combined with its global outlook, a 50%+ growth in energy storage business in 2026 is reasonable.

Meanwhile, Haibo Sichen’s revenue grew by 52%, and net profit attributable to shareholders nearly doubled, though its profitability is lower—net profit margins are 7.9% and 18%, respectively. This means Sunshine Power’s profit per GWh shipped is higher than Haibo Sichen’s for twice the volume.

Of course, Haibo Sichen’s growth potential is not lacking, as the domestic energy storage market is growing rapidly and gradually entering overseas markets, with large supply agreements from CATL.

In November 2025, Haibo Sichen signed a three-year framework agreement with CATL for at least 200 GWh. This is crucial because starting next year, energy storage cells will be in tight supply, even shortages, so securing stable battery supply is key to expanding market scale.

According to Dongwu Securities’ analysis, in 2026, Haibo Sichen’s shipments could reach 70 GW (compared to an estimated 30 GW deployment in 2025), and the unit price of energy storage systems is expected to rise, leading to a sharp increase in revenue compared to this year.

Besides downstream integrators, upstream lithium miners will also benefit significantly.

In mid-November, Ganfeng Lithium Chairman Li Liangbin stated that global lithium carbonate demand is expected to grow by 30% in 2026, with supply and demand gradually balancing. If growth reaches 40%, lithium carbonate prices could continue rising. If short-term supply and demand cannot balance, prices could hit 200,000 yuan/ton or higher.

The downstream demand for lithium mainly comes from power batteries and energy storage batteries. According to institutions, the penetration rate of new energy vehicles will continue to rise, combined with increased per-vehicle battery capacity (no subsidies below 100 km range) and demand from heavy trucks, with 2026 growth in power batteries likely exceeding 25%.

Coupled with the explosive demand for energy storage, the entire battery industry could grow by 30% or more—a highly probable scenario. However, upstream lithium mining expansion remains cautious due to painful lessons from previous overexpansion, leading to a tight supply-demand situation for lithium carbonate.

In this context, leading companies like Ganfeng Lithium and Tianqi Lithium have bottomed out and are expected to see further industry recovery as lithium prices rise.

Overall, as the industry shifts from policy support to market demand, crossing the economic inflection point, energy storage is entering a golden development period. In the industry chain, downstream system integrators with technological barriers and upstream resource owners will be the core beneficiaries of this industry explosion.
