Remember when you had to buy a case of soda just to get the flavor you wanted? That's essentially how China's renewable energy market worked until February 2025. Want to build a wind farm? You had to bundle it with energy storage, whether it made economic sense or not.

Enter Document No. 136 - China's game-changing policy that just scrapped mandatory storage allocations for renewable projects. And Wall Street is taking notice: UBS has upgraded its China BESS installation forecasts, signaling this isn't just bureaucratic shuffling - it's a market reset that will ripple through global battery pricing and procurement strategies heading into 2026.

The Problem: Forced Marriage Between Renewables and Storage

For years, China's renewable developers faced a costly requirement: pair every new wind and solar project with energy storage as a prerequisite for approval. This mandatory bundling created artificial demand that inflated the BESS market while ignoring basic economics. Storage projects were built not because they made financial sense, but because regulations demanded it.

The result? Low economic viability for storage projects with compensation rates struggling to justify investments. It was like forcing every smartphone buyer to purchase a landline - technically feasible, but economically absurd.

The Solution: Market-Based Storage Economics

Document No. 136, issued by China's NDRC and NEA in February 2025, transitions the energy storage sector from compulsory allocation to market-driven mechanisms. This shift introduces a contract-for-difference style pricing mechanism designed to promote fair market participation and restore rational power market prices.

Here's what's changing:

• No more shotgun weddings: Renewable projects can now proceed without mandatory storage pairing
• Standalone storage gets real: Grid-scale BESS projects can compete on their actual value proposition - grid services, reliability, and integration benefits
• Co-location economics improve: Storage can participate in power markets under new regulations when technical requirements are met

What This Means for 2026 Battery Markets

The numbers tell an interesting story. While China targets around 180 GW of new energy storage capacity by 2027, S&P Global forecasts a 36% decline in new installations for 2026 - about 44 GW/116 GWh compared to 2025 levels.

This isn't market collapse - it's market maturation. The transition from policy-driven to economically-driven storage deployment means:

• Quality over quantity: Projects will focus on maximizing reliability and grid integration rather than hitting arbitrary capacity targets
• Pricing pressure relief: Reduced artificial demand could stabilize battery prices globally as Chinese manufacturers adjust production to realistic market signals
• Procurement strategy shifts: International buyers may see more favorable pricing as Chinese BESS suppliers adapt to domestic market changes

The Provincial Patchwork

Not every province is singing from the same hymnal. Some regions like Shandong maintain adapted storage requirements, while others like Yunnan and Guizhou keep storage mandates entirely. This provincial variation creates a natural experiment in storage economics - expect successful models to influence national policy refinements.

Global Implications

China's policy shift matters far beyond its borders. As the world's largest battery manufacturer and energy storage market, changes in Chinese demand fundamentally alter global supply chains. The move toward economically rational storage deployment could:

• Stabilize lithium-ion battery pricing by reducing artificial demand spikes
• Accelerate innovation in storage technologies that provide genuine grid value
• Influence other markets considering their own storage mandates and incentives

Document No. 136 represents more than policy adjustment - it's China betting that market forces will drive energy storage adoption more effectively than government mandates. For the global battery industry, that's a signal worth watching as we head into 2026.

The question isn't whether energy storage will grow - it's whether it will grow smart. China's latest policy suggests they're betting on the latter.
