Circular on requirements for accelerating and promoting construction of grid-connected distributed wind power projects

Development and Reform Commissions (Energy Bureaus) of provinces (autonomous regions and municipalities), and the Xinjiang Production and Construction Corps, local branches of energy regulatory agencies, the State Grid Corporation, China Southern Power Grid Corporation, Inner Mongolia Electric Power Company：

In order to improve the utilization efficiency of distributed wind energy resources, to optimize the lay-out of wind power development, to do a good job in construction of distributed grid-connected wind power projects, and to explore effective models for the promotion of the development of distributed grid-connected wind power projects, you are hereby notified of relevant tasks and requirements as follows：

1. Accelerate and promote the development of distributed wind power。Optimizing the layout of wind power construction, and vigorously promoting the local use of wind power, are important tasks for wind power development in the "13th FYP" period。With increasingly detailed wind energy surveys and the continuous progress of low wind speed technology, accelerating and promoting the construction of distributed wind power projects that are connected to low-voltage distribution grids and have local consumption of electricity output, is of great significance, in order to optimize utilization of distributed wind energy resources in central, eastern and southern China, and -in accordance with local conditions- to improve wind energy utilization efficiency, and to promote the combined development of wind power and other distributed energy sources。

 

2. Standardize construction standards。Distributed grid-connected wind power project development and construction should be promoted in accordance with the general principles of "comprehensive planning, step-by-step implementation, locally balanced, nearby consumption"。Construction of projects should strictly meet the following technical requirements:

(1) Grid-connection shall be at voltage levels of 35 kV and below。When connected to a transformer substation with a voltage level of above 35 kV, connection shall be on the low voltage side, at a voltage level of 35 kV or below。

(2) Fully utilize the power grids existing transformer substations and distribution system facilities, prioritize connection to the grid via T-connection or double T-connection methods。

(3) On the prerequisite that the connected wind power generation capacity does not influence the safe operation of the power grid to which it is connected, comprehensively consider the total generation capacity connected at each different voltage level, and encourage connection via multiple connection points。It is strictly forbidden to feed power into grids at 110 kV (66 kV) and above。

 

3. Strengthen planning and administrative management。Provincial energy authorities shall, in accordance with the relevant technical requirements and grid-connection provisions, considering results of regional wind energy resource surveys from the previous period, on the basis of carefully screening regional grid access conditions and load levels, and in strict accordance with the principle of "nearby access, consumption within the distribution network", formulate "13th FYP" period decentralized wind power development programs for each province (region, municipality) as well as for the Xinjiang Production and Construction Corps, make these publicly available, and send copies of the program and the public notices to the National Energy Administration。

Provincial energy authorities shall consider the current status and timely implement rolling revisions to the planning. Distributed grid-connected wind power projects are not subject to restrictions from annual guiding development scale quota。For decentralized wind power projects incorporated in planning that have already received an official reply, provincial energy authorities are encouraged to study the formulation of measures to simplify project approval procedures。

Areas that have received red warnings shall focus on resolving the problem of consumption from the existing stock of wind power projects; the construction of new distributed wind power projects is temporarily suspended。

 

4. Orderly promote project construction。Project development enterprises should carefully study the definition and requirements of distributed wind power projects, and carry out project construction in strict accordance with planning and the relevant administrative requirements. Under the premise of ensured construction safety, quality and reliability, orderly advance project construction, promote technological progress and cost reduction, and encourage exploration of new models for distributed wind power development. In particular, encourage the construction of distributed wind power projects in which the producer will partly or wholly consume the electricity generated, as well as of distributed wind power projects that are used for local power balancing in micro-grids。

 

5. Strengthen grid-connection management。The State Grid Corporation of China, China Southern Power Grid Corporation, Inner Mongolia Electric Power Company and other local power supply enterprises shall sort out the location and local power load of transformer substations that have distributed wind power projects connected to them, comprehensively consider factors such safe system operation and the total generation capacity connected to the system etc., issue letters of advice on distributed grid-connected wind power project programs for each respective power supply region, and shall ensure timely connection to the grid for projects incorporated into planning。

For a distributed wind power project that does not meet the technical requirements for grid-connection as listed in article 2, the grid enterprise does not need to accept its connection to the grid or its operation。

 

6. Strengthen supervision。Energy authorities of provinces (autonomous regions, municipalities) and the XPCC should, in conjunction with the relevant technical units and power grid enterprises, carry out supervision on the whole process of development, construction and operation of distributed wind power project included in planning, and standardize the project management and supervision system, to ensure that distributed projects are implemented in accordance with the relevant requirements and provisions。

Regulatory agencies of local branches of the National Energy Administration shall carry out verification of compliance of distributed grid-connected wind power projects that have already been constructed and that are planned to be constructed, and in particular on compliance of the grid-access technology. These organization shall also carry out supervision of the construction and operation of the projects, and deliver an assessment report to the National Energy Administration. Projects that do not meet the requirements for grid-connection technology shall provide explanation, and the enterprise in charge of the project shall be ordered to make adjustments。No power generation business license shall be issued for projects that do not meet the technical requirements。

Energy regulators of local NEA branches shall monitor the construction and operation of distributed wind power within their area, and regularly publish monitoring results。
