Overview

On 19 May 2026, South Korea announced three major energy policy moves in a single day. The Ministry of Climate, Energy and Environment presented the First Renewable Energy Basic Plan, targeting 100 GW by 2030 and a power-generation share above 30% by 2035. The Ministry of Science and ICT launched the Seventh Nuclear Energy Promotion Comprehensive Plan (2027–2031), aimed at making Korea a global top nuclear power. And President Lee Jae-myung met Japanese PM Takaichi Sanae in Andong, agreeing to deepen crude oil and LNG supply-chain cooperation.

Key Facts

Renewable Energy Plan

  • 100 GW of renewable capacity by 2030 (early-achievement target)
  • Power-generation share of 30 %+ by 2035; join world’s top-10 renewable nations
  • Solar mega-zones in the Seoul metro, Chungcheong, and Gangwon regions; 44.2 GW total solar rollout
  • Cost targets by 2035: solar ≤ KRW 80/kWh, onshore wind ≤ 120/kWh, offshore wind ≤ 150/kWh
  • Shift from oil-dependent energy security to home-grown renewable production
  • Grid reforms: distributed networks, expanded battery storage (ESS)

Nuclear Energy Plan (7th Comprehensive Plan)

  • Five-year national plan covering 2027–2031; Korea’s top statutory nuclear policy
  • SMR innovation technology and civilian-led commercialisation by 2030
  • AI + SMR fusion strategy for global competitive advantage
  • 90+ experts across industry, academia, and research institutes; four subcommittees
  • Expanded applications: clean hydrogen, radiation technology

Korea–Japan Energy Cooperation

  • Summit in Andong, North Gyeongsang (19 May 2026)
  • LNG cooperation expanded on the March 2026 LNG Supply Cooperation Agreement
  • Deeper information-sharing on crude oil procurement and strategic reserves
  • Both countries to jointly lead resource supply-chain cooperation with other Asian nations
  • Korea–Japan security policy consultations elevated to vice-minister level

Significance

The three announcements reflect Korea’s dual imperative: accelerate decarbonisation while securing energy supply chains amid Middle East instability. Renewables and nuclear are framed as complementary rather than competing pillars, while the Japan partnership fills the transitional energy gap. Success depends on consistent policy execution—grid reform, SMR commercialisation, and sustained bilateral cooperation despite geopolitical shifts.
