Detailed Rules of Beijing Municipality for the Management and Control of Electricity Grid Power Supply Reliability (Trial)

In accordance with the Measures for the Supervision of Electricity Supply, the Regulations of Beijing Municipality on Optimizing Business Environment and other laws and regulations, the Rules are hereby revised for the purposes of ensuring power supply quality, improving power supply service standards and further specifying the regulatory measures for reliability of the electrical grid supply in Beijing.

I.The management work of power supply reliability

1.The power supply reliability indicator specified in the Rules is reviewed, confirmed and released by the national energy regulation authority.

2. The statistics methods for power supply reliability indicator specified in the Rules are subject to the Standards for Evaluating the Power Supply Reliability of the Power Supply System, Part 1: General Rules (DL/T836.1-2016, (hereinafter referred to as DL/T836.1-2016) issued by the National Energy Administration and also meet the standards of the IEEE Guide for Electric Power Distribution Reliability Indices (IEEE 1366-2012) issued by the Institute of Electrical and Electronics Engineers (hereinafter referred to as IEEE 1366-2012).

3. The calculation of the Average Service Availability Index (ASAI) mentioned herein shall be subject to DL/T836.1-2016 as followed.

Specifically, the system average interruption duration index (SAIDI) is calculated below:

During the statistics period, time is calculated by annual total hours.

4.The following power interruption shall be excluded from the calculation of system average interruption duration index (SAIDI):

i. Such interruption is less than 3 minutes;

ii. Interruption incidents are proposed by users or caused by users internally;

iii. Such interruption incidents are recognized by the government authority and meet the requirements of major event day defined by IEEE 1366-2012 standards.

iv. Such interruption is due to cooperating for implementing the utility work.

II. Management measures for power supply reliability

1. Power supply reliability guarantee and service policies formulated by the government shall be strictly implemented; the relevant commitments for high-quality power supply services shall be made and carried out strictly; online and offline service standards shall be publicized in a timely manner and the transparency of the management and service of power supply reliability shall be improved.

2. The review at different levels and comprehensive balance of power interruption plan shall be strengthened. The power interruption schedule shall be optimized. The impacts of scheduled power interruption on users shall be reduced continuously and repeated power interruption shall be avoided.

3. The management and control standards for scheduled power interruption shall be improved. The scope of no power interruption work shall be expanded. The annual average SAIDI and annual frequency of power interruption shall be reduced continuously.

4. The operation and maintenance management of power grid equipment shall be strengthened to timely eliminate the hidden dangers of equipment defects. Faults caused by external construction, tree lines, floating objects and so on shall be reduced, and the reliable power supply capacity of power grid equipment shall be reinforced.

5. The construction of solid smart power grid shall be strengthened. The role of power distribution automation system in rapid positioning, fault isolation and resumption of power supply at non-fault sections shall be fully utilized to minimize the range of power interruption caused by faults and improve the reliability of urban power supply.

6. The construction of the emergency system shall be improved continuously. The coordination with relevant government authorities and various departments shall be consolidated. The preparation of emergency repair personnel and spare parts shall be made in advance so as to effectively improve the emergency response capacity and avoid long-term power failure.

III. Reward and punishment management for power supply reliability

1. Reward and punishment standards

i. The State Grid Beijing Electric Power Company shall actively implement various management and control measures for power supply reliability. Neither reward nor punishment will be given in case of annual ASAI of urban power grid higher than 99% (including 99%).

ii. The punishment of RMB 50,000 will be imposed in case of annual ASAI in urban areas lower than 99%, but higher than 98% (including 98%).

iii. The punishment of RMB 200,000 will be imposed in case of annual ASAI in urban areas lower than 98%, but higher than 97% (including 97%). iv. The punishment of RMB 500,000 will be imposed in case of annual ASAI in urban areas lower than 97%.
