High-Quality Development and Construction of Distributed Photovoltaic Power Generation in Yancheng City

Guiding Opinions

 

To further standardize the development and construction management of distributed photovoltaic power generation in our city, continuously promote the safe and efficient operation of distributed photovoltaic power plants and power systems, effectively prevent and resolve safety hazards, effectively protect the lives and property of the people, and continuously promote the sustainable, healthy, and high-quality development of the distributed photovoltaic power generation industry. Based on the spirit of relevant national and provincial documents on distributed photovoltaics, and in combination with the actual situation of our city, the following guiding opinions are put forward.

 

I. Strengthen Guidance on the Planning and Layout of Distributed Photovoltaics

 

(1) Coordinate Project Development and Construction.

 

Each county (city, district) should adhere to the principle of coordinating the development of distributed photovoltaics with the high-quality development of the local economy. A comprehensive and systematic survey of distributed photovoltaic resources in the region should be conducted, guiding local power grid companies to improve the planning of distribution networks for distributed photovoltaics. The overall planning for the development and utilization of distributed photovoltaics should be considered, taking into account factors such as the regional power supply and demand situation, system absorption conditions, grid carrying capacity, and renewable energy utilization rate. The construction scale of distributed photovoltaics in the region should be determined and dynamically adjusted according to the actual situation, guiding the reasonable layout of distributed photovoltaics. The buildings and facilities on which distributed photovoltaic power generation projects are based should be legal and must not be built on illegal buildings or facilities or buildings with a hazard identification level of C or D.

 

(2) Strengthen Project Filing Management.

 

Distributed photovoltaic power generation projects shall determine the filing entity according to the principle of "who invests, who files". For individual household distributed photovoltaic power generation projects, the power supply companies in each county (city, district) can act on behalf of the local administrative approval department for centralized filing, or individuals can file themselves; for non-individual household, general industrial and commercial, and large-scale industrial and commercial distributed photovoltaic power generation projects, the investment entity shall apply for filing with the local administrative approval department. Construction before filing, delayed construction after filing, and failure to construct after filing are strictly prohibited. For projects that have not started construction or have not completed any other procedures within 2 years of filing, they shall be dealt with according to relevant regulations and procedures.

 

Project investors should submit filing materials as required and be responsible for the authenticity, legality, and completeness of the materials. If there are major changes in the project legal person, construction location, construction scale, and content, the project filing change procedures should be handled in a timely manner. Non-individual investment and development projects shall not be filed in the name of individuals. For distributed photovoltaic power generation projects in entire villages or large-scale developments, they shall not be filed in the name of the house owner by concealing the land lease relationship, and later use methods such as withdrawing power generation income from the owner's account to obtain profits.

 

(3) Strictly Scrutinize Project Qualifications.

 

The participating units of distributed photovoltaic power generation projects, such as surveying, design, construction, installation, and supervision, must have the corresponding qualifications stipulated by the state and the industry. Each participating unit should undertake business within the scope of its qualification permit. Among them, those undertaking design work must have engineering design qualifications in the power industry (new energy power generation) professional; those undertaking construction work must have power engineering general contracting, electromechanical engineering general contracting, building electromechanical installation engineering professional contracting, and power transmission and transformation engineering professional contracting qualifications (one of which is sufficient) and a safety production license; those undertaking the installation and commissioning of electrical equipment for grid-related projects such as substations and transmission lines should have a license to install (repair, test) power facilities; those undertaking supervision work must have power engineering supervision and electromechanical installation engineering supervision qualifications (one of which is sufficient).

 

II. Optimize Grid Connection Services for Distributed Photovoltaics

 

(4) Dynamically Conduct Grid Connection Assessments.

 

Local energy authorities should, in accordance with the requirements of documents such as the Jiangsu Development and Reform Commission's "Notice on High-Quality Grid Connection and Absorption of Distributed Photovoltaics in the Province" (Su Fa Gai Neng Yuan Fa [2024] 906), guide local power grid companies to conduct grid connection carrying capacity and improvement measures assessments in accordance with relevant standards and specifications. A mechanism for the quarterly release and early warning of the open capacity of the distribution network should be established based on factors such as the scale of distributed photovoltaics, load level, safe and stable operation of the system, flexible adjustment capacity, and power equipment capacity, guiding the scientific and reasonable layout of distributed photovoltaics. Power grid companies should, in conjunction with project needs, arrange grid reinforcement and substation transformation plans in a timely manner to ensure orderly grid connection and absorption.

 

(5) Accurately Promote Grid Connection Management.

 

Local energy authorities, together with local power grid companies, should prioritize the future development capacity of the distribution network and grid carrying capacity, combined with the remaining grid connection capacity in the region, and verify the safety margin of the upper-level grid equipment, to coordinate the scale and timing of grid connection for distributed photovoltaic power generation projects.

 

For new projects whose application for grid connection capacity does not exceed the remaining grid connection capacity and meets grid safety requirements, grid connection procedures can be handled according to regulations; for new projects whose application for grid connection capacity exceeds the remaining grid connection capacity and does not meet grid safety requirements, the county (city, district) power grid companies should optimize the layout of grid facilities, comprehensively improve the power supply guarantee capacity and comprehensive carrying capacity of the distribution network, and propose targeted solutions before arranging grid connection in an orderly manner.

 

New projects are encouraged to provide adjustment capacity for the power system and improve grid carrying capacity through reasonable configuration or leasing of new energy storage, adding adjustment power sources, and improving the level of terminal electrification.

 

(6) Prioritize Nearby and Low-Voltage Grid Connection.

 

The grid connection voltage level of distributed photovoltaic power generation projects shall generally follow the relevant standards of the "Technical Guide for Distribution Network Planning and Design" (DLT5729-2023). If multiple voltage levels need to be demonstrated, they should be determined based on grid conditions and through technical and economic comparison.

 

If both high and low voltage levels have grid connection conditions, low-voltage grid connection should be prioritized, considering factors such as surplus power grid capacity and on-site balance. In areas without low-voltage grid connection conditions, grid connection conditions can be improved by collecting and stepping up to medium- and high-voltage distribution networks or configuring independent energy storage at the corresponding substations (substations), and grid connection can be arranged after the grid connection system assessment meets grid safety requirements.

 

Support the construction of distributed photovoltaic power generation projects close to power loads. In areas with concentrated power loads and strong grid structures, low-voltage on-site grid connection should be adopted to achieve on-site power consumption.

 

III. Standardize the Development and Construction Order of Distributed Photovoltaics

 

(7) Ensure Project Construction Quality.

 

Project design and installation should strictly adhere to relevant standards and regulations concerning equipment, construction projects, and safety production. Key considerations include a comprehensive analysis of factors such as the building's age, structural type, load-bearing capacity, wind load, snow load, waterproofing technology, usage function, surrounding environment, safety distance, fire-fighting and rescue capabilities, and regional meteorological and geological conditions to effectively mitigate safety risks from natural disasters, fires, explosions, and collapses. Photovoltaic modules, inverters, and other equipment should pass testing by nationally recognized certification bodies and meet grid connection technical requirements; electrical components should use flame-retardant materials; modules, brackets, accessories, parts, and fasteners should use corrosion-resistant materials or undergo corrosion treatment based on the local environment, eliminating safety hazards from the source.

 

(8) Strengthen project construction supervision.

 

Investors must strictly enforce construction project safety regulations and take effective measures to prevent equipment quality, project quality, and construction safety issues. High-risk operations such as high-altitude work, hot work, live work, and lifting and hoisting must be strictly managed.

 

During rooftop construction, the number of workers and the quantity of equipment and materials stacked on a single work surface should be reasonably arranged to prevent collapses caused by excessive concentration of personnel and equipment; the construction site should be strengthened with safety protection, with guardrails installed in areas with edges and openings, and skylights on the roof, and safety nets installed around the roof; flammable and explosive materials on and around the construction site should be promptly cleared, and measures such as setting up isolation zones and equipping fire-fighting equipment should be taken to prevent fire risks caused by hot work; in the construction of factory roof projects, the emission of combustible waste gas from the factory should be checked, and the emission of combustible waste gas is strictly prohibited during hot work; installation and debugging quality management should be strengthened to ensure that the inverter, cable joints, and other connections are firm, avoiding loose connections that cause DC arcing; construction progress management should be strengthened, rushing the construction schedule is strictly prohibited, and risky operations are strictly prohibited in bad weather such as strong winds, rain, snow, and lightning.

 

(9) Improve project acceptance management.

 

Investors should organize their own project completion acceptance in accordance with relevant standards such as "Construction Specifications for Photovoltaic Power Stations" (GB 50794-2012), "Engineering Technical Specifications for Distributed Photovoltaic Power Generation Systems" (NB/T 11422-2023), and "Acceptance Specifications for Photovoltaic Power Generation Projects" (GB/T 50796-2012). After project completion acceptance, submit a grid connection acceptance application to the local power grid company. The power grid company will organize equipment acceptance and commissioning, and after passing, it will be connected to the grid.

 

During grid connection acceptance, the power grid company should focus on verifying whether the on-site installed capacity is consistent with the filing documents, access system plan, and design drawings, whether the qualifications of the design and construction (test) units meet the relevant requirements, and check the certificates of conformity, factory data, and purchase invoice headers of core grid-connected equipment such as photovoltaic modules, inverters, and grid-connected switches for consistency with the registered entity. Only after confirmation can the grid connection be made. Projects that have not been accepted by the power grid company or have failed acceptance are strictly prohibited from connecting to the grid without authorization. For projects approved for grid connection by the local power grid company, the project investor and the power grid company will sign a "Grid Dispatch Agreement", and the grid-connected project will sign a power purchase and sale contract.

 

IV. Strengthen the compliant operation management of distributed photovoltaics

 

(10) Promote the establishment of files and cards

 

Establish and improve a "bottom-up" self-reporting mechanism and a "top-down" supervision mechanism for establishing files and cards. Local energy authorities should assume the responsibility of organization and be responsible for organizing and supervising investors in establishing files and cards and reporting data audits, encouraging investors to participate in green certificate trading, green electricity trading, and other types of power market transactions. Power grid companies should play the role of "hub" in the power grid platform, cooperate with energy authorities to regularly audit the information on establishing files and cards, and for individual household distributed photovoltaic power generation projects, the power grid company is generally responsible for filling in and submitting relevant information.

 

For distributed photovoltaic power generation projects other than individual households, general industrial and commercial, and large-scale industrial and commercial projects, the project investor is responsible for filling in the information. The investor is the "first responsible person" for establishing files and cards and bears the primary responsibility for the accuracy and timeliness of the data. When the project-related situation changes, the file information should be changed immediately. Distributed photovoltaic power generation projects should complete the filing and card filling work within one month of completion and grid connection.

 

(11) Guarantee photovoltaic power quality.

 

New distributed photovoltaic power generation projects should have observable, measurable, adjustable, and controllable functions, and existing projects should be gradually retrofitted to have the corresponding functions. Distributed photovoltaics connected to the grid at a voltage level below 10 kV should be equipped with devices with necessary power quality monitoring functions, and should be able to achieve power quality index exceeding warning and active control functions. Distributed photovoltaics connected to the grid at a voltage level of 10 kV and above should conduct power quality assessment during the planning and feasibility study stage of access to the power system, configure online power quality monitoring devices, and take necessary power quality prevention and control measures.

 

Power grid companies should make full use of dispatch dedicated networks, distribution cloud systems, and electricity consumption information collection systems to promptly summarize the access information of various projects within their operating areas, analyze the data, grasp the operating status of various projects, dynamically arrange power grid operation methods, and achieve safe access and observable, measurable, adjustable, and controllable projects.

 

(12) Strengthen project operation management.

 

After project completion, investors are encouraged to establish professional teams or entrust professional companies to undertake project operation and maintenance management to ensure the safe and stable operation of distributed photovoltaic power stations.

 

Investors or operation and maintenance units should strengthen accident prevention, pay attention to local meteorological early warning and forecast information, and properly deal with adverse weather; according to safety production needs, warning signs should be hung and posted in conspicuous locations in and around the project area, and protective devices such as isolation fences should be set up in risk areas such as electric shock burns and falls from heights; the integrity, performance, and operating conditions of equipment and facilities should be regularly checked to promptly identify and eliminate faults such as module hot spots, loose contacts, poor contact, loose bolts, bracket corrosion, damp wires, and insulation breakage, and repair or replace aging cables and equipment to eliminate various safety hazards.

 

V. Build a solid safety production line for distributed photovoltaics

 

(13) Tighten and consolidate the main responsibilities.

 

The investor of a distributed photovoltaic power generation project is the main body responsible for the safety production of the project and must implement national and industry safety production management regulations, strengthen the safety production management of the entire project construction and operation process in accordance with the law, promptly eliminate project safety hazards, and ensure safe operation. Safety education for construction workers and operation and maintenance personnel should be strengthened, accident warning education should be conducted regularly, safety awareness should be strengthened, prevention capabilities should be improved, and the occurrence of accidents such as collapses, fires, electric shocks, falls from heights, and object strikes should be curbed.

 

(14) Establish and improve emergency mechanisms.

 

Investors, participating units, operation and maintenance units, and power grid companies should strengthen emergency management of distributed photovoltaic power generation projects. During construction and operation, effective measures should be formulated to properly deal with various natural disasters and accidents. Industrial and commercial distributed photovoltaic power generation projects should also formulate special emergency plans and on-site disposal plans, conduct regular drills, and reserve necessary disaster relief materials; strengthen emergency coordination and linkage, establish and improve the communication mechanism between relevant government departments and relevant units in the project location, obtain disaster information in a timely manner, and share emergency resources.

 

(15) Effectively strengthen safety supervision.

 

Local governments should implement normalized safety supervision responsibilities, actively organize emergency and energy, data, housing and urban-rural development, and other departments and power grid companies to establish a joint supervision mechanism for the safe operation of distributed photovoltaic power stations, regularly inspect the development, construction, grid connection operation, and safety production of distributed photovoltaic power stations, and order rectification of those that are not registered and connected to the grid without authorization, privately increase power generation capacity, or supply power to the outside without approval, in accordance with relevant regulations. Relevant municipal departments should earnestly fulfill their industry supervision responsibilities, carry out safety management work for distributed photovoltaic projects within their industries and units, and urge relevant enterprises and units to implement safety management responsibilities.

This opinion shall come into effect on July 1, 2025, and shall be valid until June 30, 2030. During the implementation period, if national and provincial policies are adjusted, the provisions shall prevail. Local areas may refine supporting measures based on their actual conditions.
