One example of SK Telecom's commitment to renewable energy is its partnership with Korea Hydro & Nuclear Power (KHNP) to develop a 500MW solar power plant. The project, which is expected to be completed by 2023, will be the largest solar power plant in South Korea and will supply renewable energy to SK Telecom and other companies. SK Telecom has also entered into a PPA with a wind power developer to purchase 40MW of renewable energy.

In addition to its focus on renewable energy, SK Telecom has implemented a range of energy efficiency measures across its operations. The company has implemented a smart energy management system that monitors and controls energy use in its buildings and data centers. SK Telecom has also introduced energy-efficient technologies, such as LED lighting and high-efficiency air conditioning systems, to reduce energy consumption.
