Overview
South Korea, which is still in the early stages of offshore wind power deployment, has yet to establish a clear offshore grid governance system. This issue brief examines the current situation in Korea and international case studies, emphasizing the need for Korea to establish a well-defined offshore grid governance framework.
Executive Summary
HIGHLIGHTS :
- The expansion of offshore wind power is increasing the importance of offshore grids in transmitting power to land. However, Korea lacks clear offshore grid governance, complicating efficient design and operation.
- The main models of offshore grid governance include transmission system operator (TSO)-led, generator-led, and third-party (OFTO)-led models, which differ in terms of who builds the grid, who pays for it, and how efficient it is.
- The UK emphasizes competition through an OFTO-led model, while Germany and Denmark have adopted a TSO-led model to realize economies of scale.
- South Korea needs to improve the cost burden structure of offshore grids and proactively establish a clear governance system to support the introduction of meshed offshore grids and their efficient deployment.
