Executive Summary

On November 10, 2025, the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) jointly issued the "Guiding Opinions on Promoting New Energy Consumption and Regulation." This policy document establishes a clear roadmap for China’s energy transition, mandating that by 2030, incremental electricity demand will be primarily met by new renewable energy installations, targeting an annual absorption capacity of over 200 GW of new renewable energy. By 2035, a unified national power market will play a foundational role in resource allocation.

We maintain our Outperform rating on the sector. The core investment thesis has shifted from pure capacity expansion to systemic stability and market-enabled efficiency. As the penetration of variable renewable energy (VRE) increases, the power grid faces unprecedented challenges in real-time balancing. We identify two primary investment themes arising from this structural shift:
1. System Security & Secondary Equipment: The imperative for grid stability drives demand for advanced secondary equipment (protection, automation, and control systems).
2. Marketization & Precision Metering: The transition to a market-based mechanism requires precise measurement and data infrastructure, benefiting smart meter manufacturers.

Key Takeaways

1. Policy Catalyst: A Clear Mandate for Renewable Absorption

The newly released guidelines provide quantitative clarity on China’s decarbonization path:
* 2030 Target: New energy generation must satisfy the majority of new electricity demand. The system must accommodate reasonable absorption needs for >200 GW of new renewable capacity annually.
* 2035 Vision: A unified national power market will become the primary mechanism for allocating new energy resources, supporting China’s Nationally Determined Contributions (NDCs).

This policy effectively removes ambiguity regarding the volume of renewable integration required, signaling sustained capital expenditure in grid infrastructure to handle these flows.

2. The Core Challenge: Renewable Absorption as a "System Engineering" Problem

The report highlights that power systems require real-time balance. The increasing share of renewables (wind/solar), coupled with terminal electrification, exacerbates the mismatch between generation curves and load profiles.

• The Balancing Act: Theoretically, balance can be achieved by either optimizing generation curves (via hybrid hydro-wind-solar setups) or adjusting load curves (via demand response). However, both approaches have physical and behavioral limits.
• The Solution: Grid transmission channels and energy storage are identified as the critical enablers to better fit generation with consumption. Consequently, investments in grid flexibility and storage integration are no longer optional but essential for system viability.

3. Market Mechanisms: Avoiding "Synthesis Fallacies"

The report argues that marketization is the most effective tool to manage this complex system and prevent policy contradictions ("synthesis fallacies").
* Technology Neutrality: Given the unpredictability of technological breakthroughs, the optimal strategy is to remain open to all technical solutions to minimize system costs.
* Capacity Pricing Mechanism: In the early stages, the market will likely benchmark against mature mechanisms. We anticipate that capacity tariffs for flexibility resources (including coal power and new energy storage) will align with the existing model used for pumped hydro storage. This creates a predictable revenue stream for assets that provide grid stability rather than just energy volume.

4. Strategic Investment Themes

Based on the systemic shift towards security and marketization, we recommend focusing on two specific sub-sectors:

Risks / Headwinds

While the long-term trajectory is positive, investors should monitor the following risks:

• Renewable Absorption Misses: If grid infrastructure upgrades lag behind renewable installation rates, curtailment rates may rise, potentially dampening investor sentiment and affecting the profitability of renewable generators.
• Policy Implementation Delays: The transition to a unified national power market is complex. Delays in establishing standardized trading rules or capacity pricing mechanisms could slow down revenue realization for flexibility providers.
• Technological Disruption: Rapid changes in storage technology or grid management software could render current infrastructure investments obsolete faster than anticipated, although the report suggests a "technology-neutral" approach mitigates this.
• Capital Expenditure Constraints: State-owned grid operators may face budgetary constraints that could delay the rollout of necessary secondary equipment and metering upgrades.

Rating / Sector Outlook

Rating: Outperform (Maintained)

The sector index currently stands at 10,718.07, near its 52-week high of 10,836.31, demonstrating strong relative strength against the broader market (52-week low: 6,107.84).

We believe the sector is transitioning from a phase of "capacity building" to "quality and efficiency enhancement." The NDRC/NEA guidelines validate the necessity of heavy investment in grid modernization. Unlike previous cycles driven solely by renewable installation volumes, this cycle is driven by the need for stability and market infrastructure. This provides a more durable and defensible growth narrative for companies involved in grid secondary equipment and smart metering.

The "Outperform" rating reflects our confidence that:
1. Policy support is robust and quantified (200GW/year absorption target).
2. The economic model for grid flexibility (capacity payments) is becoming clearer.
3. Leading companies in secondary equipment and metering possess strong moats and will benefit from the mandatory nature of these upgrades.

Investment View

1. Structural Shift in Value Chain

Investors should re-evaluate the power equipment value chain. Historically, primary equipment (transformers, lines) dominated capex. However, as the grid becomes a digital, real-time balancing platform, the value accrues to secondary equipment (software, chips, control systems) and data infrastructure (meters). These segments offer higher margins and stickier recurring revenue models compared to traditional hardware.

2. Why NARI Technology & Guodian Nanzi?

NARI Technology and Guodian Nanzi are leaders in grid automation and protection. As the grid complexity increases, the need for sophisticated dispatch algorithms and fault protection grows exponentially. These companies are not just hardware vendors; they are integral to the "operating system" of the Chinese power grid. Their exposure to the "system security" theme makes them direct beneficiaries of the mandate to improve renewable absorption.

3. Why Sanxing Medical & Hexing Electrical?

The move toward a unified national power market necessitates granular data. Traditional meters are insufficient for dynamic pricing and real-time trading. Sanxing Medical and Hexing Electrical are positioned to benefit from the replacement cycle toward smart, communicative meters that enable demand response and precise settlement. Furthermore, these companies have significant overseas exposure, providing a hedge against domestic policy timing risks.

4. Conclusion

The release of the "Guiding Opinions on Promoting New Energy Consumption and Regulation" marks a pivotal moment for China’s power sector. It confirms that the bottleneck is no longer renewable generation capacity, but grid absorption capability.

For institutional investors, the strategy should be to overweight companies that provide the "shovels" for this digital and structural transformation: those ensuring grid safety (Secondary Equipment) and those enabling market transactions (Smart Metering). We advise accumulating positions in high-quality leaders like NARI Technology and Sanxing Medical on any near-term volatility, viewing the 2025-2030 period as a golden age for grid modernization investments.
