China’s new energy storage sector recorded a 40‑fold increase in installed capacity by the end of 2025, reaching 136 GW nationwide. Independent energy storage accounted for more than 51% of the total for the first time.
In the past, the logic was simple: who built faster and more, won.
But the Guangdong Administrative Measures for the Construction and Operation of New Energy Storage Power Stations, released on April 24, has completely rewritten the rules.
This policy marks a definitive shift: energy storage is no longer just a “hot investment project” — it has entered the era of being core infrastructure of the power system.
01 From “The More, The Better” to “Whether We Need It”
The policy clearly states that the planning and construction of new energy storage stations shall be oriented to meeting the regulation needs of the provincial power system.
In the past, projects proceeded on a first‑to‑file basis. Now, development depends on system necessity and location suitability. The province issues unified layout guidelines, cities submit annual plans, and grid companies participate in site selection and planning.
This resolves two long‑standing pain points: local overcapacity and inefficient system allocation. The era of building storage that sits idle or operates poorly is ending.
02 From “Engineering Project” to “Grid Node”
The new regulation imposes strict requirements on grid connection, dispatch, and market participation. Energy storage can no longer simply connect to the grid — it must have dispatch capability, access the power market, and provide ancillary services.
Guangdong’s power market is also upgrading. Under the 2025 revised rules for spot electricity trading, independent energy storage can participate in two modes: bid volume & price or bid volume only.
The role of energy storage is evolving from a supporting component of renewables to a regulation hub for grid operation.
Future revenue will no longer rely on one‑time subsidies or capacity rents, but on market returns for system regulation value.
03 From “Usable Is Enough” to “Safety Is the Bottom Line”
Safety incidents have become a major bottleneck for large‑scale energy storage development. In 2025, electrochemical storage fires and accidents continued globally, including explosions in the U.S. and electrolyte leaks in Switzerland.
The new policy adopts strict safety requirements:
- Clear red lines for site selection (away from flammable and explosive areas)
- Strengthened fire protection and emergency systems
- Full‑lifecycle safety management
The logic is clear: no safety, no scale.
What This Means for Enterprises
The competitive logic of the energy storage industry is being fully restructured:
-
Investment logic changes: from “grabbing projects” to “competing on system capability”.Projects go to those who locate storage where the system truly needs it, enable dispatch, and support market participation.
-
Business model changes: from policy‑driven to market‑driven.Companies must master price forecasting, dispatch optimization, and trading strategies — not just rely on peak‑valley spreads.
-
Technical competition changes: beyond cell specs to system integration, safety design, and digital O&M.Those who can make energy storage “smarter” will lead the next stage.
National policies reinforce this trend: the “AI + Energy” action plan explicitly promotes AI for collaborative dispatch and full‑lifecycle safety in new energy storage.
The Real Dividing Line for the Energy Storage Era Has Arrived
Guangdong’s new policy is far more than additional control procedures. It sends a profound signal:
Energy storage is no longer a supporting role for renewables — it is the regulation core of the new power system.
Competition has shifted from scale to capability.Those who best understand the grid, the market, and safety will win the next five years.
