Policy Interpretation of the "Grid Safety Risk Control Measures"

To further improve the grid safety risk control mechanism, effectively prevent large-scale power outages, and ensure the safe development of the new power system, the National Energy Administration has organized the revision of the "Grid Safety Risk Control Measures (Trial)" (hereinafter referred to as the "Measures").

In 2014, the National Energy Administration issued the "Grid Safety Risk Control Measures (Trial)" (Guo Neng An Quan [2014] No. 123), which played an important role in reducing and controlling various risk factors for grid safety and preventing large-scale power outages, and was widely praised by power regulatory authorities and power companies. In recent years, laws, regulations, policy documents, and national standards such as the "Guidelines for Power System Safety and Stability" have been successively formulated (revised) and promulgated and implemented, and the state has new requirements for grid safety risk control. At the same time, the scale of the power grid has expanded rapidly over the past decade, the system operation characteristics have become increasingly complex, and grid safety risks have significantly increased, requiring further improvement of grid safety control levels through the revision of the "Measures".

The "Grid Safety Risk Control Measures" are divided into seven chapters and 35 articles. Overall, they follow the original framework structure, consolidate mature experience and practices, and on this basis, further strengthen source governance, and specifically supplement control measures that adapt to the new problems and challenges of the new power system. Five aspects have been重点 revised and improved.

First, the overall structure of the document has been optimized. Chapter Two "Grid Safety Risk Identification" and Chapter Three "Grid Safety Risk Classification" have been merged into one chapter, renamed "Grid Safety Risk Identification and Classification". Chapter Six "Coordination of Risk Control with Other Work" has been changed to "Grid Safety Risk Governance", which more clearly reflects the requirements for the entire process of grid safety risk control in terms of structure.

Second, the scope of grid safety risk control and the responsible entities have been supplemented. New grid connection entities are included in the scope of grid safety risk control, and the responsibilities of risk-related parties such as grid companies, power generation companies, power users, and owners of other grid connection entities are clarified.

Third, the principles for classifying grid safety risks have been refined. Compared with the four-level classification standard for power safety accidents in the "Regulations on Emergency Response and Investigation and Handling of Power Safety Accidents" (State Council Order No. 599), the original three-level risk has been changed to four-level risk. At the same time, considering the importance of power supply security, the complete shutdown of county-level grids is included in the four-level risk for control.

Fourth, the source governance of grid safety risks has been highlighted. The governance requirements for each link, including planning, design, construction, hidden danger investigation and management, reliability management, material management, disaster prevention, and emergency management, have been comprehensively refined and clarified.

Fifth, the connection with the actual work of grid security control has been strengthened. The annual operating mode analysis mechanism has been incorporated into grid security risk control work. New content for grid security risk control during key periods has been added, requiring grid enterprises and their power dispatching agencies to organize special safety risk analysis for peak summer and peak winter periods, and to form special risk control reports. The annual operating mode reporting and analysis meeting system, which has been formed over a long period, has been incorporated into the grid security risk control system, promoting risk control guided by scientific analysis and plant-grid collaboration driven by quantitative judgment, and urging the implementation of major risk control measures.
