Korean Southern Power discusses cost-cutting for new pumped-hydro projects

Korean Southern Power (KOSPO) held a workshop to discuss design optimization and investment cost reduction strategies for new pumped-hydro power projects.


Our take

What specific strategies is KOSPO exploring to reduce pumped-hydro costs?

KOSPO's initiative to apply Value Engineering (VE) from the design phase aims to enhance the economic viability of new pumped-hydro projects by proactively identifying cost-saving elements, addressing the challenge of large-scale investment costs.

Pumped-hydro projects, while crucial for grid stability amidst growing renewable energy, face significant economic hurdles due to their large upfront investment. KOSPO's proactive approach, focusing on Value Engineering during design and construction, aims to internalize cost efficiencies. This strategy seeks to mitigate the financial burden on the project developer, making these essential infrastructure projects more attractive and feasible for future development.
