Jiangxi should revitalize 4,710 acres of land stock and optimize the proportion of clean energy
"After the restoration of the 4,710 acres of tailings pond closed, we still feel that resources are wasted, and how to revitalize these land stocks to bring well-being to the people has been bothering us." A few days ago, Peng Caiqing, director of the Bureau of Ecology and Environment of Xinyu City, Jiangxi Province, told reporters when recalling the scene a few years ago.
Through research and evaluation, Fenyi County has found the right way - to take the road of photovoltaic industry. In recent years, Fenyi County has introduced 1.27 billion yuan of funds to develop 4,710 acres of tailings pond into a photovoltaic power plant, with an annual transmission grid of about 210 million kilowatt hours, an output value of 228 million yuan, saving 71,400 tons of standard coal, reducing carbon dioxide emissions by 210,000 tons, and reducing sulfur dioxide emissions by 6,720 tons.
Luhui Photovoltaic Power Generation Co., Ltd. in Fenyi County, Jiangxi Province, Xinyujiang Lithium Branch of New Energy Power Generation of Jiangxi Electric Power Co., Ltd., and Tangbian Branch of Fenyi Power Plant of Jiangxi Electric Power Co., Ltd. have been built one after another, bringing considerable economic and ecological benefits to Fenyi County, and also a vivid practice of the local practice of the "Two Mountains" concept.
Three photovoltaic power generation projects have been put into operation
"The direction of the development of photovoltaic power generation base has been set, but the early investment in photovoltaic power generation is huge, a small inland county with a population of more than 300,000 people, where to come up with more than a billion yuan? We can only introduce a series of preferential policies for the development of the photovoltaic industry, such as 'three exemptions and three halves', to attract a large number of photovoltaic industry 'bigwigs' to come," said Hu Xiaoyun, then director of the Fenyi County Development and Reform Commission.
The "three exemptions and three halves" mentioned by Hu Xiaoyun means that no taxes will be collected in the first 3 years, and it will be halved in the next 3 years.
Luhui Photovoltaic Power Generation Co., Ltd. was listed as a pilot demonstration of photovoltaic power generation in Fenyi County at that time, the company kept its promise, invested 650 million yuan, and selected the site of Fenyi Power Plant Closed No. 3 Ash Warehouse, covering an area of 2143.9 acres, registered Fenyi County Luhui Photovoltaic Power Generation Co., Ltd. 70 MW "Fishery and Light Complementary" photovoltaic power station, with a total capacity of 70MW, using the design scheme of "block power generation, centralized grid connection", less than two years to complete power generation, to achieve an annual power generation of more than 70 million kilowatt hours, The annual on-grid electricity is 71.5005 million kWh, the grid-connected electricity price is 1.085 yuan/kWh, and the annual output value is more than 70 million yuan.
After the success of the pilot, Xinyujiang Lithium Branch also invested 400 million yuan to build a 100MWp integrated photovoltaic and storage power generation project, using 1873.62 acres of closed land of the original Jiang lithium tailings reservoir for ecological restoration and comprehensive development and utilization, and building a solar power generation base.
In addition, the Tangbian Branch of the State Power Investment Fenyi Power Plant also invested 202.5 million yuan to build a 50MWp photovoltaic power generation project, and used 692.62 acres of closed land for No. 1 and No. 2 ash storage of the Fenyi Power Plant for ecological restoration and comprehensive development and utilization, and built a solar power station.
At present, the installed capacity of 3 large-scale photovoltaic power plants and 3 sub-stations in Fenyi County has reached 220MWp, and the transmission grid is about 210 million kWh, which has alleviated the pressure on local industrial and agricultural electricity consumption.
Free up the total metric
The reporter saw in Fenyi County Luhui Photovoltaic Power Generation Co., Ltd. that the photovoltaic panels were neatly aligned, spotless, and arranged in rows, and only a slight sound of transformer current was heard outside the huge substation building.
"How much standard coal can be saved by PV for every 1 kilowatt-hour of electricity? How much does sulphur dioxide be reduced? The reporter asked.
"The geographical environment of photovoltaic power plants in various places is different, and the value of savings and reductions has changed slightly, our company's annual power generation is more than 70 million kilowatt hours, saving 25,800 tons of standard coal every year, reducing carbon dioxide emissions by 80,800 tons, and reducing sulfur dioxide emissions by 2,400 tons." Yin Shengping, head of the power station of Luhui Photovoltaic Power Generation Co., Ltd., introduced.
Based on this calculation, the three photovoltaic power plants with a total installed capacity of 220MWp in Fenyi County are connected to the grid for power generation, which can save 71,400 tons of standard coal consumption, reduce carbon dioxide emissions by 210,000 tons, and reduce sulfur dioxide emissions by 6,720 tons.
In addition, photovoltaic power generation belongs to clean energy, and the development of photovoltaic power generation in Fenyi County has optimized the power supply structure and the proportion of clean energy, effectively reduced greenhouse gas emissions, and provided total indicators for more than 100 standardized enterprises in the county, achieving a win-win situation of social and ecological benefits.
"In the past, we always worried about the total pollutant control indicators of enterprises or projects, but now, the three photovoltaic power plants have won the total amount of pollutants for everyone, relieving the pressure on some total indicators of enterprises." Yuan Genya, the person in charge of an enterprise in the Fenyi Industrial Park, told reporters.
Help the surrounding villagers to find employment at their doorstep
"Come over and eat some honey." A few days ago, Ren Fengya, a villager who lives next to the ash warehouse by the pond of the Fenyi Power Plant, opened the nest of wild bees in the corner, cut a large bucket of honey, sealed the hive and asked the neighbors to taste it.
For decades, due to the influence of coal power generation, the fields in front of and behind the houses here were gray and smelling of coal, and butterflies and bees were once nowhere to be seen. Now that the ash warehouse is closed, a photovoltaic power station has been built, the ground is paved with grass and greenery, the surrounding area is open fenced, trees and grass are planted, the environment is beautified, butterflies are flying, and bees are back to build nests.
Photovoltaic power generation has improved the ecological environment, and the operation of photovoltaic power plants has also brought jobs - weeding, lawn mowing, module cleaning and other labor work, bringing a certain income to the local people. According to incomplete statistics, the three photovoltaic power plants pay more than 3 million yuan in labor fees every year, allowing some villagers to achieve employment at their doorsteps.
Talking about the prospect of photovoltaic power generation, Yin Shengping calculated an account for reporters: investing in a standardized photovoltaic power plant costs hundreds of millions of yuan, the service life is generally 30 years, the normal payback cycle is 8-9 years, and the next 21 years are basically net profits in addition to taxes, maintenance and labor costs; At the end of the service life, photovoltaic solar panel manufacturers recycle and recycle, and solar steel frames recycle steelmaking, with a recovery rate of 20% of the total investment, and 60% of the total investment can be reduced if the transformation and upgrading continue to serve.
In Peng Caiqing's view, so that future generations can not only enjoy rich material wealth, but also look at the starry sky, see the green mountains, and smell the fragrance of flowers, "I believe that the photovoltaic industry road will get better and better." ”
