Summary of main types of cost indicators of photovoltaic power generation projects 1 (2.9 yuan/watt)
Summary of main types of cost indicators of photovoltaic power generation projects 2 (component 3. 1 yuan/watt)
When the unit price of components is 3.2 yuan/watt-hour (the average purchasing price of components before 2065438+630 in 2007), the cost index of centralized photovoltaic power station type is 6983-8035 yuan /kw, the cost index of roof distributed photovoltaic power station is 7 150-7440 yuan /kw, and the cost index of ground distributed photovoltaic power station is 7790-8286 yuan /kw.
Summary Table of Main Types of Cost Indicators of Photovoltaic Power Generation Project 3 (3.2 yuan/Watt)
(1) photovoltaic field
20 17 version of the cost indicators can be set in centralized and decentralized ways. It is divided into three types of site conditions: desert (including Gobi, desert and saline-alkali land), grassland (including degraded grassland) and hills, and it is divided into three new capacity scales: 10MWp, 20MWp and 50MWp. The distribution mainly considers roof photovoltaic, which is divided into two new capacity scales: 10MWp and 20MWp. The differences are mainly reflected in the component supporting foundation, road, land area, cost, etc. For example, centralized (desert) uses independent foundation, and centralized (grassland) uses pile foundation (PHC prestressed pipe pile).
2. Distributed
Assign indicators to the roof. Compared with the centralized indicators, the expenses of power generation equipment foundation, traffic engineering, land use and roof renovation measures (reinforcement, roof waterproofing, maintenance of trails, etc.) are mainly deducted. ) has also increased accordingly.
Roof-less power distribution can refer to the cost index of centralized photovoltaic with the same terrain conditions and capacity scale.
3. Other types
For example, agriculture and light complement each other. Through analysis, except for Jian 'an special projects such as agricultural greenhouses, the indicators of other projects have little difference, so the indicators are not reflected separately.
(2) Step-up station/switching station
The typical booster station is newly built 1 10kV, and it is open to the outside, with a capacity of 50MW. The indicators of 20MWp photovoltaic power station are shared by 2/5 of 50MW booster stations. 370 yuan/kW
The typical switchyard is newly built, with 35KV class and 20MWp capacity. 187 yuan/kw.
Second, the cost index reference
(1) National Energy Administration's Provisions on Design Budget Estimation and Cost Standards for Photovoltaic Power Generation Projects (NB/T3201716), Budget Estimation Quota for Photovoltaic Power Generation Projects (NB/T32035-20 16), and
(2) Notice of the Ministry of Land and Resources on Issuing Land Control Indicators for Photovoltaic Power Plant Projects (No.20 15+ 1);
(three) the current power industry (power grid) project budget quota and preparation regulations;
(four) China Huaneng Group Company photovoltaic power plant equipment supervision fee charging standard (No.20 14-65);
(five) the equipment, materials and main construction contract prices that have been put into production or determined through bidding.
III. Details of cost indicators
(A) photovoltaic field cost index
1. Equipment purchase fee
1. 1 power generation equipment
(1) photovoltaic display equipment: the module is single crystal 290Wp, and the comprehensive cost indicators are given in the summary table according to 2.9 yuan/watt, 3. 1 yuan/watt and 3.2 yuan/watt respectively; The list of indicators is calculated according to 3. 1 yuan/watt. If the centralized purchase price of components fluctuates, it will be adjusted accordingly.
(2) Equipment support
Centralized photovoltaic fixed bracket fee: 396 yuan/kilowatt.
The fixed bracket is 55 tons per MW, and it costs 7200 yuan per ton. On the basis of the fixed support, the increase of the adjustable support shall not exceed 17 tons/MW, and the corresponding increase index shall not exceed 122 yuan/kW.
Distributed rooftop photovoltaic is 20 tons/MW, 15606 yuan/ton, equivalent to 3 15 yuan/kW.
1.2 confluence and distribution equipment
(1) junction box 45 yuan /kW.
(2) Inverter: 345 yuan /kW.
(3) inverter photovoltaic management system: 10 yuan /kW.
