10th Basic Energy Plan for Electricity Supply and Demand (2023-2036)

The 10th Basic Plan for Electricity Supply and Demand establishes a 15-year roadmap (2022-2036) to ensure energy security through a balanced energy mix and large-scale infrastructure investment. The plan prioritises pre-emptive reinforcement of the power grid and the expansion of transmission and substation facilities to integrate volatile renewable sources and new nuclear power. To ensure system reliability during this transition, the plan identifies a critical investment requirement of approximately KRW 45 trillion by 2036 for renewable energy backup facilities, specifically for technologies such as synchronous condensers (to provide grid inertia) and Energy Storage Systems (ESS).

A key pillar of the plan is the introduction of hydrogen and ammonia co-firing to reduce greenhouse gas emissions in the power sector. Revised targets for 2030 include generating 13.0 TWh from hydrogen and ammonia (equivalent to 2.1% of total electricity generation), which includes 6.1 TWh from hydrogen co-firing with LNG and 6.9 TWh from ammonia co-firing with coal. The plan also identifies stationary fuel cells as a critical renewable resource, projecting a rated capacity of 3,947 MW by 2036. By 2036, the government foresees a significant expansion of zero-carbon combustion, targeting 47.4 TWh of electricity generation from hydrogen and ammonia, representing 7.1% of the national energy mix. To support these technologies, the plan initiates the opening of a dedicated transaction market for low-carbon power sources like hydrogen and storage systems.
