Overview
Data from the National Energy Administration shows that by the end of July 2026, China’s installed photovoltaic (PV) capacity reached 1.286 billion kW, surpassing coal for the first time to become the largest source by installed scale. As three top-level 15th Five-Year Plans—for the new energy system, renewable development, and new power-system construction—were issued, renewables are accelerating from “capacity leader” toward “energy leader.”
On September 18, the 2026 PV-Storage Coordination and Innovation Development Conference, hosted by the China PV Industry Association, opened in Chuzhou, Anhui, discussing integration opportunities, PV-storage-compute fusion, and cyclical breakthroughs. Experts broadly agreed that PV supplies green增量 while storage provides regulation, jointly underpinning the new power system.
Background & Interpretation
1. Industry and Policy Context
“Largest by capacity” is only a start; the real test is absorption. Li Yan of Renmin University notes that wind-solar projects must do more than build plants—they need consumption capability and efficient grid connection, with new-energy utilization rate as the core metric. Policy focus has shifted from encouraging capacity to raising actual generation share via market mechanisms, grid upgrades, and storage.
2. Core Drivers and Underlying Mechanism
The crux of PV-storage synergy is the “business case.” At the conference, experts noted that in some provinces storage revenue comes mainly from spot price arbitrage, frequency regulation, and capacity tariffs—all with ceilings and rule-driven volatility. PV plants face dual tests of full market entry and higher credible output. Li Yan stressed that storage’s main revenue (peak-valley pricing) still mismatches investment and O&M costs, leaving many projects under profit pressure.
3. Market Structure and Industry Chain Effects
Zhang Yufeng of AVIC Securities emphasized that when evaluating PV-storage projects, the weight of policy rules and absorption conditions should exceed raw capacity numbers. The industry is shifting from “build-heavy” to “operations-heavy,” and “PV + storage + trading” may form new competitiveness. During the 14th Five-Year Plan, Anhui’s PV-storage revenue grew from ~80 billion to over 380 billion yuan, with Chuzhou gathering 184 firms—evidence of clustering.
Implications & Outlook
Near term, declining storage costs via scale and iteration should gradually open space, with the pace of electricity-market reform (spot, ancillary, capacity tariffs) the key variable. Longer term, as grid-forming storage, long-duration storage, and smart dispatch mature, new energy can acquire the four system values of traditional sources: energy, ancillary services, capacity, and green certificates.
Takeaways for Industry Participants
PV and storage firms should move beyond “capacity competition” to model local market rules and revenue; grid and system integrators must plan absorption channels and regulation resources upfront. For investors, regional absorption capacity and policy fit should outweigh scale in due diligence.
