Sejong Power Plant

Introduction

Located in the heart of Sejong City, South Korea’s vibrant administrative capital, the Sejong Power Plant—officially the Shinsejong Combined Cycle Power Plant—stands as a landmark of innovation and sustainable energy. Developed to meet the city’s rapidly growing energy needs and support South Korea's drive toward carbon neutrality, the plant features advanced combined cycle systems, hydrogen-natural gas fuel blends, and stringent emissions controls. Today, it not only powers the city but also serves as an educational destination, inviting visitors to engage with cutting-edge green technologies and South Korea’s energy transition. Its proximity to attractions such as Sejong National Arboretum and Sejong Lake Park makes it the perfect starting point for exploring the city’s blend of nature, technology, and culture (NS Energy, Ministry of Environment, Sejong City Tourism).

Historical Background and Development

Origins and Strategic Importance

The Sejong Power Plant is a cornerstone of Sejong City’s infrastructure, created to facilitate the decentralization of government from Seoul and support the city’s residential and administrative growth since its 2012 founding. The need for reliable, sustainable energy drove the project’s approval in June 2021, with construction beginning in September that year under the leadership of the Korea Southern Power Company (KOSPO), a subsidiary of KEPCO (NS Energy).

Construction and Milestones

Built in collaboration with global and local partners—including General Electric, Hanjin Heavy Industries & Construction, and Ssangyong—the plant was designed to utilize next-generation combined cycle technology. The facility began operations in early 2024, supplying electricity and heat to both the national grid and Sejong’s district heating system, reinforcing the city’s smart, sustainable urban model.

Technological Highlights

• Combined Cycle Efficiency: Integrates gas and steam turbines to achieve over 64% efficiency, producing a total output of 630 MW.
• Hydrogen-Natural Gas Co-Firing: Utilizes GE’s H-class 60 Hz gas turbine, capable of running on hydrogen blends, aligning with Korea’s carbon reduction goals.
• Emission Controls: Advanced systems reduce nitrogen oxide (NOx) emissions to as low as 3 ppm—among the lowest in the world.
• District Heating: Supplies heat for local residential and municipal buildings, maximizing energy use and efficiency.
• Smart Grid Integration: Real-time monitoring supports energy balancing and the integration of renewable sources.

These technologies place the Sejong Power Plant at the forefront of clean energy innovation, making it a valuable learning site for visitors.
