KEPCO H1 2026 Profit Falls 16.6% to ₩4.91 Trillion as Iran War Drives Fuel Cost Surge

The Quick Take

• Korea Electric Power Corporation (KEPCO) posted H1 2026 consolidated operating profit of ₩4.91 trillion, down 16.6% year-on-year, as surging fuel costs offset record revenue of ₩46.32 trillion.
• Net profit fell 21.0% to ₩2.80 trillion, reflecting the combined impact of higher coal and LNG procurement costs and lower electricity tariff adjustments relative to fuel cost inflation.
• KEPCO warned that Middle East fuel cost pressures — driven by the Iran war — will intensify in H2 2026, setting up further profit pressure in the back half of the year.

Korea Electric Power Corporation, the state-owned utility that dominates South Korea's electricity generation and distribution, disclosed H1 2026 results showing revenue up 0.3% to ₩46.32 trillion but operating profit falling 16.6% to ₩4.91 trillion. Net profit dropped 21.0% to ₩2.80 trillion. The divergence between modest revenue growth and sharply falling profit reflects KEPCO's structurally challenging position: electricity tariffs are politically constrained and adjusted infrequently, while fuel input costs — coal and LNG — have risen significantly amid the Iran war-driven energy market disruption. KEPCO's business model as a regulated utility gives it limited ability to pass through rapid fuel cost increases to end consumers in real time.

The H1 result has sector-wide implications for Korean industrial competitiveness. KEPCO's rising fuel costs translate into upward pressure on industrial electricity tariffs, which affects the operating costs of Korea's energy-intensive export sectors — semiconductors, steel, chemicals, and petrochemicals. Samsung Electronics and POSCO, among the largest industrial electricity consumers, monitor KEPCO's fuel cost trajectory closely. Meanwhile, KEPCO's weakening profit position raises questions about its ability to fund Korea's renewable energy transition capital expenditures, which require sustained investment in offshore wind, nuclear restart, and grid modernisation.

Forward signals include KEPCO's H2 2026 guidance on fuel cost assumptions and any tariff adjustment submissions to Korea's energy regulator. Iran war resolution remains the most important variable for LNG and coal procurement costs. The macro variable is KEPCO's debt level and sovereign backing: as a state entity, KEPCO can run sustained losses with government support, but mounting accumulated losses would eventually force politically difficult electricity tariff increases — the rate at which the government allows those adjustments is the key policy variable determining KEPCO's H2 profit trajectory.
