Operation of the largest 100MW solar power generation complex in Korea using waste salt farms
Domestic wind power generator demonstration test bed, leading the localization of the wind power industry
[에너지신문] Jeonnam Yeonggwang is attracting attention as the center of the Green New Deal. It is evaluated that it has been reborn as a mecca of renewable energy by using the waste salt farm as a solar power generation site to create the largest solar power complex in Korea with a scale of 100 MW, as well as serving as a test bed for the demonstration of a domestic wind power generator.
The Yeonggwang solar power plant was completed in June last year. Boasting a 100MW scale, the largest single solar power plant in Korea, it produces 13GWh of electricity per year that 62,000 households can use for one year.
In particular, it is also equipped with 312MWh ESS facilities, enabling stable solar power generation. The total project cost was 349.2 billion won.
The reason why Yeongwang Solar is particularly attracting attention is that it is a 100MW ultra-large photovoltaic power generation facility, and that the waste salt farm, which was difficult to find use, has been reborn as a solar power generation site.
The construction of a 2MW-scale solar power plant jointly operated by Yeombu (saltfield tenants) and villagers who lost their jobs due to the closure of the salt farm was recorded as an exemplary case of solving the problem of using idle land and securing resident acceptance, which are the challenges of solar power plants. have.
In addition, in promoting the large-scale power generation complex construction project, most of the major equipment such as solar modules, structures, and batteries were used as domestic products, invigorating the manufacturing industry and contributing to revitalization of the local economy by creating jobs.
It is playing a role as a test bed for wind power as well as solar power, the largest salt farm in Korea.
The Yeongwang wind power test bed is being operated by establishing a performance evaluation base such as transmission facilities and meteorological observation towers to support the certification and demonstration of large and small wind turbines by domestic wind turbine manufacturers.
In the first phase project implemented from 2011 to 2014, the demonstration and certification of domestic turbines such as Unison (2.3MW, 4.2MW) and Doosan Heavy Industries & Construction (3MW) were provided. The certified turbines were supplied to nearby Yeonggwang wind power plants and offshore wind power demonstration complexes in the Southwest Sea, contributing to the expansion of the supply of domestic turbines.
Since last year, a second-stage expansion project is underway to build a test bed for large wind turbines of 5MW or higher. A total project cost of 26 billion won will be invested in the second phase project, which will be implemented by 2022.
In the case of an 8MW large-capacity offshore wind power system being developed by Doosan Heavy Industries & Construction through government R&D support, it is expected to be supplied to large-scale offshore wind power projects such as Sinan, Southwest Sea, and Ulsan after obtaining actual and certification through the second phase project.
Using the experience of operating the Yeongwang Demonstration Complex, the government plans to build a wind power infrastructure suitable for each region, such as the Changwon Nucelle Test Bed and the Gunsan Offshore Wind Power Industry Support Center. Through this, it is expected not only to demonstrate domestic wind power equipment, but also to foster professional manpower.
R&D support for the development of large wind turbines and localization of major parts is also continuously expanding. According to the Ministry of Industry, the wind power R&D support budget is increasing annually to 27.9 billion won in 2017, 34.2 billion won in 2018, 60.2 billion won in 2019, and 86 billion won in 2020.
Meanwhile, Minister of Industry Sung Yun-mo visited the Yeonggwang solar power plant and wind power test bed site on the 27th to check the conditions for expansion of renewable energy and encourage the people involved.
Minister Seong emphasized, “In order to achieve carbon neutrality in 2050, the supply of renewable energy must play a pivotal role.” In the process, securing resident acceptance and technology development are the most important.
In addition, he said, “We plan to expand the public participation-type renewable energy supply model in which local residents participate and share the profits of generation, while strengthening policy support such as continuous R&D expansion and related infrastructure construction to enhance domestic renewable energy competitiveness.”
