Overview
On September 18, the “2026 Photovoltaic and Storage Coordinated Application Innovation Development Conference,” hosted by the China Photovoltaic Industry Association, opened in Chuzhou, Anhui. A headline figure drew wide attention: by the end of July, national solar PV installed capacity reached 1.286 billion kW, surpassing coal-fired power for the first time to become the largest source by installed capacity. The National Energy Administration had earlier confirmed that PV had historically overtaken coal.
The milestone is not isolated. This year, three top-level “15th Five-Year” plans—covering the new energy system, renewable energy development, and new power system construction—were rolled out, all sharing a common theme: moving renewables from “capacity dominance” to “energy-output dominance.” Solar provides green increments; storage provides regulation. Together they are turning from an option into a necessity for the new power system.
Background & Interpretation
1. Industry Context & Policy Landscape
For over a decade, China’s PV sector expanded on scale. Once renewable generation crossed a threshold, system carrying capacity became the main constraint. Policy focus has shifted from “ensuring and promoting absorption” to “ensuring support, output, and source value,” requiring renewables to deliver the system value of conventional sources.
2. Core Drivers & Underlying Mechanisms
Officials from the Ministry of Industry and Information Technology noted that while PV and new storage hold global leadership, expanded scale has intensified supply-demand imbalance, limited absorption capacity, and earnings pressure. Zheng Hua of North China Electric Power University argues future PV-storage systems must deliver four values: energy value, ancillary-service value, capacity value, and green-power value. PV is inherently time-volatile and cannot alone provide inertia or reserve; storage modulates across time scales, making variable renewables more controllable.
3. Value Chain & Competitive Impact
At the roundtable, multiple companies said PV firms are moving from “making PV products” to “PV-integrated development.” As renewables enter market-based trading, value depends not only on generation but also on price and curtailment reduction. “PV-storage trading” may become a new competitive capability. Regionally, Anhui’s PV-storage revenue grew from about 80 billion yuan to over 380 billion yuan during the 14th Five-Year period; Chuzhou alone hosts 184 PV-storage firms, signaling strong clustering.
Implications & Outlook
In the near term, PV-storage plants shift from “construction-heavy” to “operations-heavy”—accurate modeling and good dispatch decide winners. Storage revenue still relies on peak-valley spreads, frequency regulation, and capacity tariffs, all with ceilings and rule-driven volatility. Medium to long term, integrated PV-storage bidding and AI-driven dispatch (EMS, trading agents, optimization algorithms) will lift joint efficiency.
Key variables: provincial capacity-tariff and peak-load rules, ancillary-market openness, and source-grid-load-storage pilot progress.
Takeaways for Industry Participants
- Investors: do not copy-paste projects; model returns per province and grid node; pilot before scaling.
- Equipment and integrators: compete on technology, quality, and brand rather than price and scale; pursue compute-power coordination and zero-carbon parks.
- Operators: prioritize cash flow and high-margin orders; use long-term operations to offset shipment-ranking pressure.
