Singapore International Energy Week 2025 — Preview & Key Themes
Overview
Singapore International Energy Week (SIEW) is Asia's most influential annual energy forum, convening government ministers, energy regulators, oil and gas executives, and clean-energy investors to discuss the region's energy priorities. Organised by Singapore's Energy Market Authority (EMA), it encompasses the Singapore International Energy Conference (SIEC), the Asia Clean Energy Summit (ACES), and a trade exhibition.
SIEW 2025 occurs against a backdrop of volatile Asian LNG markets, accelerating Southeast Asian energy transitions, and Singapore's own strategic repositioning from a fossil fuel hub toward a clean-energy trading and services centre. For context on Asian LNG markets heading into the event, see our analysis from Gastech 2025.
Key themes: SIEW 2025
1. Asian LNG demand and JKM price dynamics
The Japan-Korea Marker (JKM) LNG price has remained volatile since the 2022 European supply shock. In 2025 Asian LNG demand has been shaped by China's energy mix decisions, Japan's nuclear restart programme, and South Korea's policy choices between coal and LNG for power generation. SIEW 2025 will probe how long-term LNG contracts are evolving, whether US LNG volumes are flowing efficiently to Asia, and what the price outlook for 2026–2027 looks like as new supply comes online.
2. Singapore's National Hydrogen Strategy
Singapore has committed to importing low-carbon hydrogen (green and blue) to decarbonise its power sector, targeting hydrogen for 50% of electricity generation by 2050. SIEW 2025 will feature discussions on the progress of hydrogen import pilot projects, certification schemes (green hydrogen standards), and the economics of the hydrogen supply chain from Australia, the Middle East, and Chile.
3. Maritime decarbonisation and green bunkering
Singapore is the world's largest bunkering port by volume. The IMO's 2023 revised GHG strategy (targeting net-zero by 2050) has set a clock on conventional bunker fuel demand. SIEW 2025 includes a dedicated Maritime Decarbonisation session examining methanol, ammonia, and LNG as transition marine fuels, and the infrastructure investments required at Jurong Island and Tuas to handle them.
4. Southeast Asia just transition
The ASEAN region faces a particular challenge: rapid energy demand growth combined with high dependence on coal for power generation. The Just Energy Transition Partnerships (JETPs) announced for Vietnam, Indonesia, and the Philippines at COP26 and COP27 are now being implemented — or struggling to be. SIEW 2025 will assess progress. For broader Southeast Asia context see our analysis of Southeast Asia fuel subsidy reforms.
Asian LNG market outlook entering SIEW 2025
| Country | LNG import volume (2025 est., mt) | Key 2025 trend |
|---|---|---|
| Japan | ~65 mt | Nuclear restarts reducing LNG burn; long-term contract portfolio renewal |
| China | ~80 mt | Moderate growth; domestic gas production rising; coal competition |
| South Korea | ~45 mt | Policy uncertainty on nuclear; LNG in power grid balancing role |
| India | ~28 mt | Strong growth; new FSRU terminals; price sensitivity limits full potential |
| SE Asia combined | ~18 mt | Vietnam, Thailand, Philippines adding import capacity |
Singapore as a global energy trading hub
Singapore's oil market infrastructure includes oil product storage on Jurong Island (one of the world's largest onshore storage concentrations), the SGX derivatives exchange (Singapore Exchange), and a concentration of oil trading houses, major oil company regional headquarters, and physical brokers. The Singapore complex refining margin — which blends light and heavy crude processing in a tropical market — is used globally as a benchmark for Asian refining economics.
This infrastructure makes Singapore uniquely positioned to host discussions on fuel price formation, LNG price indices, and the transition to alternative bunkering fuels. For how refinery economics connect to retail pump prices globally, see our guide to what makes up the price at the pump.
Southeast Asia's energy transition challenge
ASEAN collectively targets 35% renewable energy share in its energy mix by 2025 (from 15% in 2015) — a target that is broadly off-track. Coal still accounts for ~40% of power generation. Fuel subsidies, including the large Indonesia and Malaysia programmes, make it harder to incentivise conservation and alternatives, as discussed in our analysis of Southeast Asia's energy transition.
Green bunkering: Singapore's strategic bet
Singapore's Maritime and Port Authority (MPA) has allocated green lane berths for methanol bunkering and is building LNG bunkering infrastructure at Tuas. The economic viability of green bunkering depends on the price premium of alternative fuels versus conventional very-low-sulfur fuel oil (VLSFO) — a spread that remains wide in 2025 but is expected to narrow as scale increases and IMO regulations tighten post-2030.
Frequently asked questions
-
When is Singapore International Energy Week 2025?
- SIEW 2025 takes place 27–31 October 2025 at Marina Bay Sands, Singapore. It is organised by Singapore's Energy Market Authority (EMA) and includes the Singapore International Energy Conference (SIEC) and the Asia Clean Energy Summit (ACES).
-
What is SIEW and why is it important?
- SIEW is Asia's premier annual energy week. Singapore's strategic role as an oil trading hub, LNG bunkering port, and regional price-setting centre makes SIEW a key venue for shaping Asian energy policy — particularly for LNG, clean energy, and oil trading discussions.
-
What are the key topics at SIEW 2025?
- SIEW 2025 focuses on Asian LNG demand and JKM price dynamics, Singapore's hydrogen import strategy, maritime decarbonisation (green bunkering with methanol, ammonia, LNG), Southeast Asia's just energy transition, and the role of carbon markets in financing Asian clean energy.
