The conference brief
Upcoming editionSingapore International Energy Week (SIEW) 2026
SIEW is Singapore's flagship annual energy week, organized by the Energy Market Authority, combining a two-day government-and-industry SIEW Summit (expanded from one day for 2026, with a new IAEA forum) with an exhibition and several co-located partner conferences covering clean energy, gas, grids and downstream fuels. It concentrates regulators, utility executives and cross-border energy policymakers from across Asia-Pacific in one week at one venue.

01 / Make the call
Is this the right room?
Emitree's assessment of audience fit. Conference access does not establish buying intent or guarantee meetings.
Consider it if
You sell into power utilities, grid operators, renewable energy developers, gas and LNG players, or nuclear supply chains anywhere in Asia-Pacific. SIEW week bundles the Summit with co-located tracks (Asia Clean Energy Summit, Asia Gas Markets Conference, Future of the Grid) for sub-vertical targeting under one roof.
Consider another event if
Your product is narrowly carbon-accounting or ESG-disclosure software with no energy-infrastructure angle. SIEW's 2026 program centers on energy policy, grids, nuclear, and fuels.
02 / Understand the audience
Who attends
The official 2026 factsheet describes the SIEW Summit as gathering high-level speakers from government, industry and international organisations, and the program it publishes includes a Singapore-IEA Forum, a Singapore-IRENA High-Level Forum, the inaugural IAEA@SIEW forum and an ASEAN Energy Regulatory Forum. That structure points to a senior mix of ministers, regulators, utility C-suite and multilateral agency leaders. Individual 2026 speakers are not named in the factsheet, and no buyer-to-seller ratio is published.
How large is the event?
The official 2026 factsheet states that in 2025, SIEW attracted more than 23,000 onsite attendees from over 70 countries. This is an organizer-reported actual for the prior (2025) edition, not a confirmed 2026 attendance figure or target.

Tickets and eligibility
Delegate fees for SIEW Summit passes are not published on the public event site, and registration runs through a separate portal at register.siew.gov.sg. Treat pricing as on request and check that portal directly for current rates. Pricing for the co-located Asia Clean Energy Summit is published separately and listed under that event's own entry.
Rates and eligibility can change. Confirm the current price, tax treatment and included sessions with the organizer.

Before you book
Asia Clean Energy Summit, Asia Gas Markets Conference, Future of the Grid and other partner events run inside SIEW week at the same Marina Bay Sands venue on overlapping days, so one trip can cover several of them, but each partner event sells its own registration at its own price and has to be booked separately.

The practical questions
Before you decide
Is Singapore International Energy Week (SIEW) 2026 still upcoming?
This edition is listed for October 26–30, 2026. Check the organizer's page for changes before booking.
Where can I find the Singapore International Energy Week (SIEW) exhibitor list?
We have not linked a public exhibitor directory for this edition. Ask the organizer about current directories and attendee access.
Does a company listing confirm who will attend?
A sponsor, exhibitor or speaker listing establishes that published role. It does not establish which employees will attend or whether they are buying. Previous-edition examples remain historical.
How can Emitree help with Singapore International Energy Week (SIEW)?
We research relevant accounts using public conference sources and any lists you provide. We qualify the accounts against your offer, run agreed outreach and record replies and meetings in your CRM.
