Its core business is the production, delivery, and support of electric power in the Republic of Korea, with additional holdings and associate investments linked to the wider power ecosystem. ## Products & services • Electricity transmission and distribution • Nuclear power generation • Non-nuclear power generation • Plant maintenance and engineering services • Investment and holding activities in energy-related entities - **Transmission and distribution** (45%) — High-voltage and network operations that deliver electricity to end users. - **Electric power generation (Nuclear)** (24%) — Nuclear generation assets that produce baseload electricity. - **Electric power generation (Non-nuclear)** (20%) — Conventional and renewable/non-nuclear generation assets. - **Plant maintenance & engineering service** (3%) — Technical services for operating, maintaining, and engineering power facilities. - **Others and consolidation adjustments** (8%) — Miscellaneous energy-related activities and intercompany eliminations. - Electricity transmission and distribution - Nuclear power generation - Non-nuclear power generation - Plant maintenance and engineering services - Investment and holding activities in energy-related entities ## Customers KEPCO sells electricity primarily to customers in the Republic of Korea, with service delivered through the national power system. Its customer base includes households, businesses, public institutions, and industrial users that depend on grid-connected electricity supply, while related engineering services and investment activities support the broader power sector. - **Residential electricity users** (primary) — Households that buy retail power through the national grid for essential consumption. - **Commercial and industrial users** (primary) — Businesses and factories that buy electricity for operations and productivity. - **Public and institutional customers** (secondary) — Government and institutional users served through the Korean electricity system. - **Power-sector counterparties** (secondary) — Project companies and associates that use engineering, maintenance, or investment support. - Households supplied through the national distribution network - Commercial and industrial users buying grid electricity - Public-sector and institutional customers in Korea - Energy-sector counterparties using maintenance and engineering services - Associated entities and project companies in the power ecosystem ## Geography The group’s main operating market is the Republic of Korea, where electricity sales are conducted and where most operating assets are located. The disclosed geographic information indicates that external customer revenue and non-current assets are concentrated domestically, making the Korean market the key driver of operations and exposure. - Core electricity sales are conducted in the Republic of Korea - Domestic customers drive the majority of external revenue - Most generation, transmission, and network assets are located in Korea - Korean regulation and tariff decisions strongly affect operations ## Strategy KEPCO’s strategic position is tied to operating and expanding the national electricity network, maintaining generation capacity, and supporting system reliability. The company also manages long-duration capital investment, tariff decisions, and partnerships across the broader energy value chain, which are central to its role in Korea’s power infrastructure. - **Transmission and substation investment planning** (medium-term) — The grid is the backbone of the business and requires long-cycle capital allocation to maintain reliability. - **Generation portfolio management** (medium-term) — Nuclear and non-nuclear assets shape supply reliability and system flexibility. - **Tariff and funding discipline** (short-term) — Electricity tariff rates and borrowing decisions affect the economics of the regulated utility model. - **Energy-sector investments and partnerships** (medium-term) — Associates and joint ventures extend reach into power projects and related services. - Maintain reliable transmission and distribution service - Plan long-term transmission and substation investment - Manage generation mix across nuclear and non-nuclear assets - Use associate investments to extend the energy platform - Balance capital spending with tariff and funding decisions ## Risks KEPCO is exposed to regulated utility risks, including tariff-setting, large capital requirements, and operating complexity across generation and grid assets. Asset impairment, fuel and purchased-power assumptions, and dependence on the Korean market can all materially affect reported results and long-term returns. - **Tariff regulation and political oversight** [high] — Utility pricing affects the ability to recover costs and fund infrastructure investment. - **Impairment of power assets** [high] — Generation and network assets are capital-intensive and sensitive to cash-flow assumptions. - **Fuel and purchased power cost volatility** [medium] — Generation margins depend on assumed fuel prices and purchased electricity costs. - **Concentration in the Republic of Korea** [high] — The business is primarily domestic, so local regulation and demand conditions dominate outcomes. - **Contingent liabilities from guarantees and associates** [medium] — The group may support related entities through debt guarantees and investments. - Tariff decisions can limit recovery of costs and capital investment - Large fixed assets create impairment risk if assumptions weaken - Fuel and purchased power costs affect generation economics - Concentration in Korea creates regulatory and country-specific exposure - Guarantees and associate investments add contingent risk ## Accounting The most important accounting judgment is impairment testing for power assets, where recoverable value is estimated using discounted cash flows based on sales volumes, prices, discount rates, and purchased-power costs. Because the business is asset-heavy and long-lived, depreciation, goodwill, and consolidation adjustments also have a meaningful impact on reported results, while segment and geographic reporting reflects the structure of the regulated utility and subsidiary group. - **Non-financial asset impairment** — Can materially change carrying values of generation and network assets - **Goodwill impairment** — Affects intangible assets and profit in impairment periods - **Consolidation and segment allocations** — Shapes segment-level asset and liability presentation - **Long-lived asset depreciation** — Affects earnings and asset book values over time - Impairment testing relies on long-term cash-flow assumptions - Depreciation of generation and grid assets affects operating results - Goodwill requires ongoing assessment for impairment - Consolidation adjustments reflect a large subsidiary and associate structure - Segment reporting separates transmission, nuclear, non-nuclear, and services --- *Last updated: 2026-09-28T12:04:13.506089+00:00*
