Five minutes to teach you how to develop a photovoltaic power plant? (Jiangsu chapter)

I. Basic information

area

Jiangsu Province has an area of ​​107,200 square kilometers, accounting for 1.12% of China. As of 2015, Jiangsu Province has a total of 1 sub-provincial city (Nanjing, jurisdiction over 11 municipal districts), 12 prefecture-level cities (45 municipal districts), 21 county-level cities, 21 counties, and counties (cities). It includes three pilot counties (cities) in Jiangsu Province, including Kunshan, Taixing, and Fuyang.

Terrain appearance resources

The topography of Jiangsu is dominated by plains, with an area of ​​more than 70,000 square kilometers, accounting for more than 70% of Jiangsu's area. The ratio ranks first among all provinces in China. It is mainly composed of the Plain of North Jiangsu, the Huanghuai Plain, the Jianghuai Plain, the coastal plain, and the Yangtze River Delta Plain. . Jiangsu has a low-lying land with more rivers and lakes, and plains and water account for more than 90% of Jiangsu Province. The proportion still ranks first in all provinces in China. This is the geographical feature of Jiangsu.

As of 2013, Jiangsu had 68.94 million mu of cultivated land and 0.87 mu of cultivated land per capita. The beach covers 10.31 million mu, accounting for one-fourth of China.

Electricity status

Jiangsu is a major province of economy with rapid economic development and people’s living standards. The demand for electricity continues to grow. Jiangsu is also a small province of resources, and electricity supply and demand is in a tight balance for a long time. At the same time, Jiangsu's new energy industry is emerging. In the face of this situation, the Jiangsu Provincial Government has proposed a power development strategy of “calls from outside the region and power supply in the province, and vigorously develop new energy”.

It is reported that from 1993 to 2012, Guangdong's total social power consumption has ranked first in the country for 20 consecutive years. In 2013, Jiangsu Province witnessed a historic breakthrough in electricity consumption by the whole society, an increase of 8.20% over the previous year, reaching 495.7 billion kwh, surpassing the 483.103 billion kilowatt-hours of electricity consumption in Guangdong Province and ranking first in the country.

Prospects

Jiangsu Province is a region rich in solar energy resources. The total solar radiation value is the largest in the southwest, and the total solar radiation is relatively small in the eastern and northern regions. The sunshine hours are long throughout the year, the temperature is low, and the photovoltaic conversion efficiency is high. The total area of ​​residential areas in Jiangsu Province is 13.17 billion square meters, and the photovoltaic cell area on the roof can be up to 189 million square meters, and the average annual power generation is estimated to be about 36.6 billion kWh.

In view of the abundant solar energy resources in Jiangsu Province and the increasing importance of the country for the use of renewable energy, Jiangsu Province will increase the development of solar energy resources from photovoltaic power generation, solar thermal power generation, and solar thermal utilization in the future. By 2020, the province's photovoltaic power generation will add 2,550 megawatts of installed capacity.

II. Analysis of earnings

III. Distributed Roof Project Development Process

(1) Detailed development process

1. Preliminary inspection/planning site selection

2. Project Pre-Feasibility Study/Project Proposal

3. Project feasibility study

4. Project Evaluation and Decision

5. Project Filing Application

(2) Preliminary investigation of project resources

1 user's roof area, structure. (Based on architectural drawings or photo information can be examined)

2 Peripheral conditions (traffic, material procurement, market labor, roads, hydropower) (through field trips)

3 User power consumption, voltage level, length of outgoing line, grid structure and annual load, consumed load capacity, voltage level of access system, and access interval verification. (can be examined through electrical drawings)

4 Electricity prices and subsidies (please refer to above)

IV. Pre-project construction materials and approval documents

1 Conduct feasibility study analysis (detailed analysis of solar energy resources, accurate calculation of power generation, accurate calculation of project investment, and detailed financial management. Selection of equipment, implementation of major technical solutions)

2 Project filing application report, enter the record list of the province (city)

Project Filing Application Report

According to the requirements of the development and reform commissions at all levels of the urban and rural areas, the required information should be submitted to refer to the Nanjing municipal case:

1 The project company filed a project for filing a red-headed file of the company, including: project name, project address, project area, investment funds, etc.

2 Go to the Municipal Development and Reform Commission website http://download the “Enterprise Investment Project Filing Application Form” and fill in the completed

3 Project company business license, organization code certificate (original and copy)

4 Land Certificate and Real Estate Certificate of the Project Location (Original and Copy)

V. Grid connection process

The individual users of the grid-connected application process need to bring with them ID cards, account books, real estate certificates, and related materials. Business users bring relevant materials such as business licenses, legal identity cards, land certificates, real estate licenses, and project materials to the local power supply business office. Application

1 Owner submits application for grid connection and goes to the local grid company for filing

2 Grid companies accept the grid-connected system plan and formulate the access system plan

3 The owner confirms the access system plan and adjusts the repeated application according to the actual situation

4Power grid company issued access advice letter

5 owners to carry out project approval and project construction

6After the construction of the owner is completed, apply for acceptance and debugging of the grid connection

7 The grid enterprise accepts the application for grid acceptance and commissioning, and installs an energy metering device (the original meter is converted into a bidirectional meter)

8 Check and acceptance of power grid companies and their commissioning, and sign and order power sales contracts and grid-connected dispatch agreements with owners

9 official grid connection
