Against the backdrop of the global energy transition and the deepening of China's "dual carbon" goals, a massive investment initiative shaping the future power system has commenced. How will the grid—the essential "skeleton" and "lifeblood" supporting the energy revolution—be upgraded and restructured? On January 19, Goldman Sachs released a significant research report titled "China Grid Technology: '15th Five-Year' Grid Investment Provides Solid Support for Domestic Growth; Positive for NARI, Sieyuan, etc.," explicitly stating that China's State Grid's fixed asset investment during the "15th Five-Year" period (2026-2030) is targeting a historic high of 4 trillion yuan. This not only implies stable annual investments exceeding 800 billion yuan but also signals a fundamental shift in grid construction logic—from cyclical fluctuations to a structural reshaping aimed at integrating renewable energy and supporting the digital economy. The report clearly indicates that the core driver behind this record investment stems from a fundamental shift in the power system's mission: it is no longer merely about transmitting electricity; its central task has transformed into efficiently accommodating volatile green power from wind and solar sources. Goldman Sachs argues that a new grid platform centered on ultra-high voltage (UHV), smart distribution networks, and digitalization is the only viable path to host a high proportion of wind and photovoltaic integration while meeting the demands of new quality loads like AI computing power. —Scale Reaches a "New High," but Growth Logic Has Changed Underpinning the grid sector's prosperity over the next five years is an unprecedented investment base. The Goldman Sachs report reveals that State Grid's 4 trillion yuan investment target for the "15th Five-Year" period represents a substantial 40% increase compared to the approximately 2.8 trillion yuan invested during the "14th Five-Year" period. This growth rate far exceeds that of the previous five-year plan, establishing a benchmark for rapid industry expansion. However, more important than the sheer scale is the evolution in the growth rationale. Goldman Sachs analysis points out that the investment is clearly divided into two major phases: in 2026, UHV is expected to be the fastest-growing segment, with a projected year-on-year increase of 24%, forming a clear growth trajectory; from 2028 to 2030, grid investment will increasingly shift towards smart grid infrastructure. This signifies that the grid's "nervous system" (software, control, sensing) and "capillaries" (distribution networks, microgrids) will receive unprecedented reinforcement. —Distribution Emerges as the "Main Theme," Investment Structure Quietly Reshaped A profound structural change is underway: the growth rate and proportion of distribution network investment are set to comprehensively surpass those of transmission investment. Goldman Sachs predicts that from 2026 to 2030, the share of distribution investment within the total investment will rise from the current 57% to 59%. This is not merely a simple proportional adjustment but a fundamental redefinition of the grid's functional role. The report emphasizes that as distributed generation, electric vehicle charging piles, and virtual power plants connect extensively to the distribution network, the traditional passive distribution grid must be upgraded into an intelligent platform capable of active dispatch and flexible interaction. Consequently, investments in smart meters, automation terminals, and distributed control systems will become a more sustained growth engine than traditional tower and line construction. —Supply-Demand Gap Becomes "Inevitable," Smart Investment is the Only Solution Goldman Sachs' models paint a pressing picture of the future: by 2030, renewable energy is expected to account for 30% of total power generation. Its inherent intermittency and volatility will place immense strain on stable grid operation. The report states unequivocally that a higher proportion of renewable energy integration will inevitably lead to increased grid volatility, structurally necessitating higher levels of intelligent investment. Therefore, the investment rhythm is tightly linked to grid stability requirements. Goldman Sachs forecasts that investment growth might temporarily slow during 2027-2028 due to project cycles, but will re-accelerate in 2029-2030 to address more severe balancing challenges then. The smart grid has transitioned from a "nice-to-have" enhancement to an essential "necessity" for system security. —Market Focus Shifts to "Leaders," Competitive Landscape Becomes Clear As the industry enters a period of certain prosperity, who will benefit the most? Goldman Sachs directs attention to the equipment leaders that already dominate the market. Citing the latest State Grid tender data, the report notes that market share is increasingly concentrating towards leading enterprises. In key equipment categories such as GIS (Gas Insulated Switchgear), circuit breakers, and transformers, leading companies represented by Sieyuan Electric Co.,Ltd. (002028.SZ), Pinggao Electric (600312.SH), and Tbea Co.,Ltd. (600089.SH) collectively hold the vast majority of the market share. This "the strong get stronger" dynamic implies that as the overall demand "pie" expands, leading companies with technological, brand, and delivery advantages will capture more significant market share and exhibit greater earnings flexibility. —A System Upgrade Defining the Next Decade State Grid's 4 trillion yuan blueprint for the "15th Five-Year" period extends far beyond simple infrastructure expansion. It represents a comprehensive upgrade of the energy system's underlying architecture, with the core objective of building a more resilient, intelligent, and flexible new power system. In the short term, the earnings potential from UHV and main grid upgrades is clearly visible. In the long term, the vast opportunities孕育ed by grid digitalization and distribution network intelligence will become a持续 value proposition for years to come. Goldman Sachs' report reveals that within the grand narrative of energy transition, the foundation for a structural bull market in grid investment has already been firmly laid.
