Tongchuan National level photovoltaic power generation technology leading base “Photovoltaic +”Loess Plateau Ecological Restoration Project

    Description
    Intro

    Tongchuan City Yijun County PV power generation technology lead base is one of the three national PV power generation technology lead bases approved by the National Energy Administration in November 2017. It aims to promote the technological progress of PV power generation, accelerate the transformation of technological achievements into applications, and lay the foundation for PV power generation to achieve grid parity. 1.The base size is 500 MW. It is divided into two lots, each of which is 250 megawatts. 2.The base project is expected to have a total investment of 3.5 billion yuan (photovoltaic power generation + composite part). 3.Base positioning "photovoltaic power generation + high-efficiency agriculture + sightseeing and tourism + poverty alleviation". 4.The power plant was connected to the grid on June 30, 2019; enjoy a feed-in tariff of 0.75 RMB / kWh. 5.On June 11, 2018, the National Energy Administration commissioned by the General Institute of Water and Power to organize the project unit preferences to determine the investment unit, namely. Lot 1: Longi Green Energy Technology Co. (51%) China Three Gorges New Energy Co. (49%) 6.Module technology: Longi monocrystalline P-type PERC stacked double-sided module with 20.66% front-side conversion efficiency and 345Wp+ power for 60-chip type.

    Description

    This innovative project is highly compatible with the SDGs objectives. The loess plateau tableland area is composed of loess soils covering the terraced plateau of river valleys, which are distributed in long strips along the river valleys. Current severe channel erosion has led to problems of fragmentation and decomposition of the loess loam, causing severe ecological pressure on the plateau tableland area. Thus, ecological management needs in the loess plateau tableland zone.

    Contribution to SDG Implementation

    1. Priority is given to employing Yijun County's poor households with archived cards to work in PV agricultural industrial parks. Through the agricultural cooperative Northwest University of Agricultural Science and Technology, the National Cooperative Innovation Strategic Alliance for Modern Agricultural PV Industry, and the Yijun County Bureau of Agriculture, agricultural production skills training has not only increased the labor income of poor households but also improved their skills and experience in agricultural production and management. 2. The operation and maintenance work such as component cleaning during the operation of the power plant is handed over to the poor households in Yijun County based on the market price. The 250 MW is divided into 125 O&M units, and each unit or group of units is assigned to poor households for component cleaning. Taking the benchmark array area as a benchmark, the power generation gain of the array area under the responsibility of the poor households was taken as the performance assessment basis of the poor households' labor income through comparison, which not only effectively increased the income of the poor households, but also improved the operation effect of the power station.

    Implementation methodologies

    1- Opinions of the Ministry of Land and Resources, the Poverty Alleviation Office of the State Council, and the National Energy Administration on Supporting Photovoltaic Poverty Alleviation and Regulating Land for the Photovoltaic Power Generation Industry 2-Shaanxi Provincial Department of Land and Resources "on support for photovoltaic industry land to help alleviate poverty"

    Results

    1.Creating a technological landscape zone. 2.Light - Unique lighting combinations. 3.Nong-happy rural experience. 4.Travel- profound wellness tourism. 5.Get involved in the eco-experience of photovoltaic agro-tourism.

    Factors and Constraints

    1.The table loam area is a flat surface on the loess plateau, and the ecological benefits of the project should at least ensure that the loam surface is not reduced. Sudden heavy rainfall in the loess area may cause soil erosion and have devastating consequences on the loess surface, so the PV project area should design a more detailed ecological construction plan for rainwater harvesting and drainage in response to the potential heavy rainfall. 2.Use PV power to build a land IoT to establish a more detailed ecological monitoring system for water resources, soil, loess, and agriculture in the terraced loess. 3.A more detailed plan for water resource management in the plateau loess area needs to be designed.

    Sustainability and replicability

    1.The plateau of loess plateau is an important part of the cultural cradle of the Chinese nation, and the great rejuvenation of the Chinese nation requires the restoration of the ecosystem of the loess plateau. Photovoltaic power plants are of great historical significance to the ecological restoration of the plateau loess plateau. 2.Second, the digital facility farming system built in some of the greenhouses has realized the prototype of the Internet of Things for PV-enabled land. This is the most promoted innovation of this project. 3.Third, module cleaning and other operation and maintenance work and land clearing of seedlings create jobs, which is very meaningful for local people to alleviate poverty and increase income PV operation and maintenance.
