A recently released power‑sector plan indicates that during the 15th Five-Year Plan period, State Grid aims to commission 15 ultra‑high‑voltage DC transmission projects, boosting interprovincial and interregional transmission capacity by 35%. This means that clean energy from the western and northern regions will be delivered more efficiently to the load centers in eastern and central China. However, while UHV technology addresses the challenge of “being able to transmit,” ensuring that the power can “reach its destination and be effectively utilized” depends on the carrying capacity of the distribution grid.

This logic is reshaping the investment landscape of the power grid. According to authoritative analysis, among the overall 4-trillion-yuan investment package, distribution‑network spending is expected to account for more than 60%, with an annual compound growth rate of 10%. The modernization of the distribution network is no longer limited to expanding transmission capacity; it is evolving toward flexibility, intelligence, and digitalization. It must accommodate local consumption of distributed photovoltaic generation, orderly charging of electric vehicles, and flexible, two‑way interactions with user‑side energy storage. This dual‑focus approach—balancing a robust transmission grid with an intelligent distribution network—creates differentiated growth opportunities for enterprises at different levels.

For companies specializing in transmission and distribution projects, it is essential to both capitalize on the market growth driven by UHV‑related infrastructure and keep pace with the smart‑grid transformation of distribution networks, while strengthening their technological capabilities in areas such as relay protection and automated commissioning. The profound restructuring of the power‑grid construction landscape signals that, over the next five years, the power‑construction sector will enter a new competitive landscape characterized by diversified development and simultaneous improvements in both scale and quality.

Qualification upgrades have become a competitive barrier, and the trend toward specialization in transmission and transformation projects is becoming increasingly pronounced.

As grid‑infrastructure development places ever‑higher demands on safety and quality, market‑entry standards have become increasingly stringent. Holding installation (repair, testing) permits and professional contracting qualifications issued by the National Energy Administration and the housing and urban–rural development authorities has become a fundamental prerequisite for bidding on major projects. The level of these qualifications not only reflects an enterprise’s capabilities but also establishes critical technical barriers in an intensely competitive market.

The explosive growth of photovoltaics and energy storage is giving rise to a new, untapped market for grid‑connection technical services.

Driven by the “dual carbon” goals, distributed photovoltaic systems and next‑generation energy storage projects are experiencing explosive growth. However, the large-scale integration of new‑energy assets into the grid poses significant challenges to grid‑connection safety and stability. This has given rise to a specialized market for technical services related to new‑energy grid integration—covering areas such as the development of connection system plans, grid‑connection commissioning and testing, and grid‑related trials—making it a burgeoning “new blue ocean” in the power‑technology services sector.
