South Korea renewable energy policy 2026: K-Taxonomy, offshore wind, hydrogen ambitions
South Korea's renewable energy policy in 2026 is shaped by the 10th Basic Electricity Supply Plan targeting 28% renewables by 2030, aggressive offshore wind tenders (target: 14.3 GW by 2030), and the K-Taxonomy for green finance. Hyundai and Samsung's hydrogen ambitions are central. Current renewable capacity at ~30 GW.
In 50 words: South Korea's renewable policy in 2026 is shaped by the 10th Basic Electricity Supply Plan targeting 28% renewables by 2030, aggressive offshore wind tenders (14.3 GW by 2030 target), and the K-Taxonomy for green finance. Hyundai and Samsung's hydrogen ambitions central. Current renewable capacity ~30 GW.
Where Korea stands
Cumulative renewable installed capacity Q1 2026:
- Solar PV: ~22 GW (largely rooftop + commercial)
- Onshore wind: ~2.5 GW
- Offshore wind: ~150 MW
- Bioenergy + other: ~5 GW
- Total: ~30 GW
The 2030 target: ~80 GW combined renewable. Massive build-out required, particularly offshore wind.
Policy framework — the 10th Basic Plan
Korea's energy planning works through 10-year basic electricity supply plans. The 10th Plan (released 2023, updated 2025) sets:
- Renewables: 28.7% of generation by 2030 (vs 13% in 2024)
- Nuclear: 32.4% (Korea has resumed nuclear expansion under conservative government)
- Coal: 16.3% (declining)
- LNG: 22.9% (transitional)
The Plan ratchets through implementation milestones. 2026 is mid-cycle execution year.
Offshore wind — the centerpiece
Korea's offshore wind tender program is now the most active in Asia after China. Target:
- 14.3 GW operational by 2030
- Multiple ongoing tender rounds in 2025–2026
Major sites:
- Sinan-gun (southwest coast) — Korea's largest offshore zone
- Ulsan (southeast) — co-located with industrial demand
- Jeju Island — Korea's renewable energy hub
Lead developers:
- Korea National Oil Corporation
- Hanwha Q CELLS
- SK Innovation
- Equinor (Norway, with Korean partners)
- Orsted (Denmark, with Korean partners)
- TotalEnergies
Hydrogen — Korea's strategic bet
Korea has positioned hydrogen as a national strategic priority. Major elements:
Hydrogen import strategy
Korea will be a major importer of green hydrogen / ammonia given limited domestic renewable resource. Targets: 1.96 million tonnes/year by 2030, 27.9 million tonnes/year by 2050.
Industrial pilots
- Hyundai Steel: green steel pilot
- POSCO: H2-DRI (hydrogen direct reduction iron) commercial trials
- Hyundai Motor: fuel cell vehicle scale
Hydrogen Promotion Act
2021 law established Hydrogen Economy framework. Updates through 2025 supporting imports + domestic infrastructure.
K-Taxonomy
Korea's "K-Taxonomy" (Korean Green Taxonomy) — finalised 2022, expanded 2024 — defines what qualifies as green investment. Notable inclusions:
- Renewable energy generation
- Nuclear (controversial inclusion in Korea, aligned with EU Taxonomy approach)
- Hydrogen production and infrastructure
- Green steel and chemicals
- Carbon capture
The K-Taxonomy guides Korean institutional investor allocation. Sets the framework for green bond issuance.
What developers should know
For renewable developers and EPCs targeting Korea:
- Offshore wind is the primary opportunity through 2030
- Joint ventures with Korean local partners often required
- Strong domestic content preferences
- Steady tariff structure (no extreme price swings)
- Korean banks willing to finance with K-Taxonomy alignment
What to watch next
The next major offshore wind tender (expected Q3 2026, ~2 GW) will reveal whether Korean offshore wind economics remain competitive. If tariffs compress further, the pipeline accelerates dramatically.
