Overview
On September 12, at the 2026 Beijing CIFTIS Intelligent Manufacturing and Power Supply forum, the International Academician Science and Technology Innovation Center, the Beijing Power Supply Industry Association, and Kazakh parties signed a cooperation agreement for a 7GW PV-storage-charging power-generation project worth $8 billion—among the largest China–Kazakhstan green-energy deals. It will build seven clusters, deploy 12–18GWh of storage, construct 2,500–4,000 km of private grid, and assemble a PPA portfolio covering industry, data centers, and telecom.
Separately, Huaneng’s 61MW/244MWh molten-salt storage under its incremental distribution-grid green-supply project entered operation on September 17, supplying industrial steam to the Dalate economic zone in Inner Mongolia, cutting ~680,000 tonnes of CO2 annually, paired with 32MW/128MWh electrochemical storage.
Background & Interpretation
1. Industry and Policy Context
Amid the global energy transition and deepening Belt and Road cooperation, storage is upgrading from a “complement” to a “necessity” of new-energy systems. The China–Kazakhstan project places storage at the core of peak-shaving and supply stability via a full “generate–transmit–store–sell” chain; domestically, molten-salt long-duration storage answers the new power system’s need for cross-period energy transfer.
2. Core Drivers and Underlying Mechanism
The economics of large overseas PV-storage projects rest on three pillars: scaled renewable resources, stable PPA off-take, and dispatchability after storage smooths volatility. The Kazakhstan deal locks long-term demand via PPA, reducing financing and grid uncertainties. Domestic molten-salt storage follows an “electricity–heat–steam” path, turning renewable power into direct industrial-steam demand, complementing short-duration electrochemical storage.
3. Market Structure and Industry Chain Effects
China’s storage manufacturing and engineering prowess are converting into export competitiveness. Beyond this deal, Energy China, Envision, and SPIC have multiple wind-with-storage projects in Central Asia; a 3.45MW/7.72MWh storage at Kazakhstan’s northern 220kV substation completed commissioning as the country’s first qualified system. Domestic long-duration storage moving from demo to commercial also opens incremental markets for equipment makers.
Implications & Outlook
Near term, super-sized overseas orders will lift exports of storage systems, inverters, and grid equipment; long-duration storage’s penetration in industrial-steam and park-energy scenarios should rise. Key variables are overseas approvals, financing closure, EPC cadence, and how fast domestic market reform delivers multiple revenue streams for storage.
Takeaways for Industry Participants
Storage exporters need integrated “equipment + engineering + finance” capability and must prioritize PPA and local grid access; domestic players should tailor long-duration storage to scenarios (industrial steam, incremental grids) rather than rely only on peak-valley spreads. Investors should favor leaders with overseas delivery and system-integration strength.
