Lotte Super said in a statement on December 1 that the company has built solar power plants on rooftops of affiliated stores and a logistics center. The total size of the rooftop power plant is 5,100 square meters, which is about the size of 20 tennis courts. The company's stores and logistics centers across the country use a total of about 130,000 megawatt-hours of electricity every year. Lotte Super predicted that about 10 percent of total consumed electricity can be replaced with renewable energy generated using rooftop solar panels.
South Korea has focused on turning various idle spaces into eco-friendly power generation venues to reduce carbon emissions. Hanwha Q Cells, the solar cell-making wing of South Korea's Hanwha Group, is leading a 96 billion won ($86 million) project to build 60 megawatt-class solar power facilities on factory roofs and idle spaces in the southern industrial city of Pohang by partnering with Korea East-West Power, a state power generation company.
