KEPCO Completes $700 Million Green Bond Issuance
Korea Electric Power Corporation (KEPCO), South Korea’s state-owned electricity utility, has successfully raised $700 million through a dual-tranche U.S. dollar green bond sale, demonstrating strong investor confidence in sustainable finance.
The transaction attracted orders worth more than $2.5 billion, making the offering more than three times oversubscribed. The bonds are scheduled to be issued on 21 July 2026, according to Reuters.
The strong response reflects continued investor demand for high-quality green bonds issued by investment-grade borrowers, particularly those financing clean energy infrastructure.
Two-Part Bond Structure
KEPCO divided the transaction into two separate bond tranches to attract a wider range of investors.
The first tranche consists of a $400 million three-year floating-rate green bond, paying the Secured Overnight Financing Rate (SOFR) plus 0.62 percentage points.
The second tranche is a $300 million five-year fixed-rate bond carrying a 4.75% coupon. The bonds were priced at 99.534 cents on the dollar, slightly below face value.
The dual structure allows KEPCO to diversify its funding sources while appealing to both floating-rate and fixed-income investors.
Funds Target Renewable Energy Projects
As a certified green bond issuance, the proceeds will be used exclusively for environmentally sustainable investments under KEPCO’s Sustainable Finance Framework.
Eligible projects include renewable electricity generation, energy efficiency improvements, and other initiatives that contribute to reducing greenhouse gas emissions and supporting South Korea’s energy transition.
Green bonds have become an increasingly important financing tool for utilities seeking to modernize electricity systems while meeting climate commitments.

Investor Demand Sends Positive Market Signal
The offering’s $2.5 billion order book represents one of KEPCO’s strongest recent international debt issuances.
Oversubscription allows issuers to secure financing at more favorable borrowing costs because investors compete for a limited allocation rather than requiring higher yields.
The pricing established through this transaction also creates new benchmark levels for KEPCO’s outstanding U.S. dollar debt, potentially lowering financing costs for future bond issuances.
If demand for the company’s green debt remains strong, KEPCO could access international capital markets more efficiently to support additional clean energy investments.
Green Bonds Continue Expanding Globally
The successful issuance reflects the continued expansion of the global green bond market, where governments, utilities, financial institutions, and corporations are increasingly turning to sustainable debt instruments to finance projects that support climate action and the transition to low-carbon economies. Green bonds have become a key source of long-term capital for renewable energy, clean transportation, energy-efficient buildings, grid modernization, and other environmentally focused infrastructure.
Utilities remain among the largest issuers of green bonds as they invest heavily in renewable power generation, electricity transmission upgrades, battery energy storage systems, and energy efficiency improvements needed to support more resilient and lower-carbon electricity networks. At the same time, growing institutional demand for environmental, social and governance (ESG) investments has strengthened investor appetite for green-labelled securities, particularly those issued by highly rated public-sector entities and investment-grade companies. As countries continue pursuing net-zero targets, the global green bond market is expected to play an increasingly important role in financing the next generation of sustainable infrastructure projects.
Outlook
KEPCO’s oversubscribed $700 million green bond issuance highlights the strong confidence that global investors continue to place in sustainable infrastructure financing and investment-grade green assets. As South Korea accelerates its transition toward cleaner energy systems through expanded renewable generation, improved grid infrastructure, and greater energy efficiency, green bonds are expected to remain one of the utility’s most important sources of long-term financing.
The strong demand seen in this transaction may also help reduce KEPCO’s future borrowing costs, making it easier to refinance existing debt and raise additional capital for future renewable energy and sustainability initiatives. More broadly, continued investor appetite for green bonds signals growing confidence that sustainable finance will remain central to funding the global energy transition, supporting utilities and governments as they invest in cleaner, more resilient, and more secure electricity systems over the coming decade.
