Overview

Renewable Energy as a Next-Generation Growth Engine

Renewable energy refers to energy that comes from naturally replenishable resources and can be continuously used and recycled, such as solar energy, hydropower, wind power, biomass, and waste repurposing.

No.1 Renewable Energy Public Enterprise

K-water is the no. 1 company in the new and renewable energy sector, with 4.5% of the renewable energy market in Korea, and operates 1,431 MW of eco-friendly power plants, including hydropower, wind power, solar power, and tidal power. We will build new business models, such as sustainable energy facilities, and lead the national energy policy through the continuous development of various new and renewable energy technologies combining water and energy.

Projects

Sustainable Clean Energy Together with the Local Community

As K-water continues to grow as a global leading company, we are striving to include the voices of local community stakeholders by expanding its public-led development projects into a people-participatory, eco-friendly energy business model that thrives with the community.

Hydroelectric and Tidal Power Generation, Leading Energy Sources to Realize a Clean Nation

K-water produces 2,664GWh of electricity annually by operating 176 generators at 113 locations, including hydropower, solar power, and wind power. Sihwa Tidal Power Plant, the world’s largest capacity tidal plant (254MW), not only produces 455GWH of electricity annually but also improves capacity tidal plant (254MW), not only produces 455GWH of electricity annually but also improves the water quality of Sihwa Lake through efficient sea water circulation thanks to facility operations.

Development Status of Floating Solar Power

Since the pilot installation of a 2.4kW floating solar power module at Juam Dam in 2009, K-water succeeded in the commercialization of the world’s first floating solar power system utilizing the dam’s surface by installing a 500kW floating solar power generation facility at Hapcheon Dam in 2012. We currently operate a total of 7 power plants with a capacity of 6MW, including Boryeong and Chungju.

Expansion of Hydrothermal Energy

K-water continuously creates new industries by utilizing the added value water provides. Starting with the construction of the Juam Dam power plant in 2006, we have been developing and expanding the urban distributed hydrothermal energy system by using raw water from regional water suppl facilities. Thermal energy from river water was designated as new renewable energy (October 1st, 2019), and efforts have been made to expand the hydrothermal energy sector by increasing demand in public buildings, national projects, and private heavy energy-consuming buildings.
