KEPCO confirms Seongsong-myeon as site for new 345kV substation after 3-year delay

Korea Electric Power Corporation (KEPCO) announced that Seongsong-myeon, Gochang-gun, Jeollabuk-do was selected as the final site for the 345kV Sinchang Substation, resolving a nearly three-year delay through unanimous resident agreement.


Our take

How did KEPCO overcome local opposition to secure a site for a critical substation?

The successful siting of the 345kV Sinchang Substation, after three years of delay, demonstrates a shift in local community engagement, where KEPCO's direct communication and residents' recognition of economic benefits (job creation, business attraction) for their declining region led to unanimous approval from 34 villages.

KEPCO's strategy of bypassing traditional local government and opposition groups to engage directly with residents, coupled with highlighting tangible economic benefits like business attraction and job creation, effectively reframed the substation from a "not-in-my-backyard" (NIMBY) facility into a **catalyst for regional revitalization**. This approach addressed the specific socio-economic challenges of Seongsong-myeon, transforming local resistance into proactive support by aligning the project with the community's urgent need for development and population retention.

For investors — This case suggests that proactive, direct engagement with local communities and emphasizing tangible economic benefits can significantly accelerate grid infrastructure projects in Korea, potentially reducing development timelines and risks for DER investors reliant on grid connections.

Watch: KEPCO's future adoption of direct resident engagement models for other grid infrastructure projects.
