Singapore International Energy Week, known as SIEW, is the annual energy policy and industry gathering run by Singapore's Energy Market Authority. This is the nineteenth edition. It is not a single conference but a week long cluster: a central summit organised by the authority, a set of government to government and multilateral forums, and a group of partner conferences and exhibitions that run alongside it. The organiser describes the audience as energy professionals, policymakers and commentators, and says the week is intended to bring together policymakers, industry leaders and innovators from outside Singapore as well as within it.
The week runs from the twenty-sixth to the thirtieth of October. The year is 2026. The Energy Market Authority has named the Sands Expo and Convention Centre at Marina Bay Sands in Singapore as the official venue.
The stated theme is Connecting Energy Systems, Powering Tomorrow. On the organiser's own account, the programme concentrates on two things. The first is dependable and resilient energy systems, including regional grid integration and cross border cooperation, which is the long running policy question for Southeast Asia. The second is the lower carbon supply options now being assessed seriously in the region, with the authority specifically naming advanced nuclear, biomethane, geothermal energy, and carbon capture, utilisation and storage.
Structurally, the central SIEW Summit has been expanded to two days, and the programme includes a Singapore and International Energy Agency forum, a Singapore and International Renewable Energy Agency forum, and an International Atomic Energy Agency forum. Partner events listed by the organiser include the Asia Clean Energy Summit, the Asia Gas Markets Conference, Future of the Grid, and the Asian Downstream Summit. A sustainable fuels track has been added to the Asia Clean Energy Summit. The authority also runs SIEWConnects sessions outside Singapore, in Australia, China and the United States.
For senior executives, the significance lies partly in who convenes it. SIEW is run by the regulator rather than by a commercial exhibition company, and the organiser frames the summit as the place where policymakers, industry leaders and innovators address the energy challenges facing the sector. Questions of regional grid integration and cross border cooperation, which the authority has put at the centre of this edition, bear directly on project financing, offtake and siting decisions across Southeast Asia. Having the gas and downstream conferences running in the same week as the clean energy programme also puts incumbent fuel businesses and transition players in the same building. For utilities, large industrial energy buyers, infrastructure investors and anyone with regional generation or fuel exposure, it is an efficient week for reading official direction.
