Additionally, private-sector involvement in hydropower projects can help speed up the development process and reduce the financial burden on the government.
Types of Hydropower in South Korea
1. Large-Scale Hydropower
South Korea has several large-scale hydropower plants, primarily located along the country's major rivers, including the Han River, Nakdong River, and Geum River. These plants have been in operation for several decades and provide a significant portion of the country’s renewable energy supply. Large-scale hydropower systems are typically based on dam reservoirs and offer substantial power generation capacity, often contributing hundreds of megawatts to the national grid.
The role of large-scale hydropower plants in providing baseload electricity generation makes them a cornerstone of South Korea's renewable energy strategy. However, these plants have limited room for expansion due to geographical and environmental constraints. As such, South Korea’s focus is now shifting towards optimizing existing facilities and integrating them with other energy sources to improve efficiency.
2. Small-Scale and Micro-Hydropower
While large-scale hydropower projects remain important, small-scale and micro-hydropower systems are growing in popularity in South Korea. These smaller systems are capable of generating power from lower water flow rates and are often deployed in rural or off-grid areas. Micro-hydropower systems are particularly attractive for South Korea’s mountainous terrain, where smaller rivers and streams can be used to generate electricity in remote locations.
In addition to their environmental benefits, small and micro-hydropower systems have lower installation and maintenance costs compared to large-scale projects, making them an economically viable solution for community-based energy generation. These systems are also modular, which means they can be scaled up or down depending on energy demand.
3. Pumped-Storage Hydropower (PSH)
Pumped-storage hydropower (PSH) is a key component of South Korea’s efforts to integrate renewable energy into the national grid. PSH facilities act as large-scale energy storage systems, helping to balance supply and demand in the grid. These plants work by using excess electricity to pump water to a higher elevation during periods of low demand, and then releasing the water to generate electricity during periods of peak demand.
South Korea is focusing on expanding its pumped-storage capacity to improve grid flexibility, particularly as the share of variable renewable energy sources like wind and solar increases. The government is investing in new PSH plants to complement the growth of other renewable energy technologies and provide a stable, reliable power supply.
