The plan targets early delivery of 100 GW of renewable capacity, keeps nuclear options under review, and calls for prebuilt grid connections and reused water to support data centers and advanced manufacturing. South Korea's Ministry of Climate, Energy and Environment set out its second-half 2026 policy program on August 4, placing electricity and water infrastructure at the center of the country's AI and semiconductor plans. The announcement is a government roadmap rather than a completed construction program: it combines renewable-energy expansion, possible nuclear additions, grid and storage investment, electricity-market changes, and water-system upgrades. ### Power before the data centers arrive The ministry said it wants to reach 100 gigawatts of renewable capacity ahead of schedule. Its measures include large solar projects on reclaimed land and in border regions, more rooftop solar, and faster offshore-wind development. Nuclear generation remains part of the planned supply mix, while decisions on new reactors and small modular reactors are to be considered through the next long-term electricity plan. The grid plan is explicitly tied to artificial-intelligence data centers and advanced industrial parks. The ministry proposes building network capacity before demand arrives, expanding battery storage and pumped-storage hydropower, and upgrading existing transmission lines where possible. It also plans to revise regional and data-center electricity pricing and create a dedicated power-system regulator. ### Water becomes an AI-infrastructure constraint The policy treats cooling and industrial water as a second bottleneck. Measures include shortening the review cycle for the national water plan, linking reservoirs and other existing systems more flexibly, reducing losses in bulk-water networks, reusing treated wastewater for new industrial sites, and developing options such as groundwater storage dams and mobile desalination. Independent reporting from The Korea Times described the same August 4 briefing and its focus on supplying AI data centers and semiconductor plants with cleaner power and dependable water. The official release does not say every unit of electricity will come from renewables; it preserves a role for nuclear power and leaves major implementation decisions to later planning and consultation. For infrastructure teams, the practical signal is that Korean AI capacity will increasingly be evaluated alongside grid connection, tariff design, storage, cooling water, and regional siting. The milestones that matter next are the detailed power plan, project approvals, funded transmission and water works, and evidence that announced capacity reaches operation. ## Key Points - 1South Korea's August 4 policy program ties AI-data-center and semiconductor growth to advance grid construction, storage, and more flexible water infrastructure. - 2The ministry aims to accelerate toward 100 GW of renewable capacity while keeping nuclear and small-modular-reactor decisions within the next long-term power plan. - 3The announcement is a policy roadmap, so delivery depends on later planning, approvals, funding, and completed power and water projects. ## Scoring Rationale A national policy that links AI and semiconductor expansion to power, storage, tariff, and water-system changes is materially relevant to infrastructure planning. Its impact is tempered because the August 4 briefing is a roadmap, not proof that the proposed capacity and networks have been built. ## Sources Primary source and supporting public references used for this report.
