Scaling Up Demand Flexibility
From peak management to efficient system operation This report has been developed as part of the International Energy Agency (IEA) Digital Demand-Driven Electricity Networks (3DEN) initiative to examine the growing importance of demand flexibility in electricity systems amid rising demand, increased renewable energy integration and the electrification of power systems. Case studies in chronological order to examine the changing role of demand flexibility over time from South Africa (2025), Thailand (2030) and Ireland (2035) demonstrate how demand flexibility improves reliability, reduces costs, supports renewables integration and manages network constraints. To realise these benefits, the report emphasises the role for…

Southeast Asia Energy Outlook 2019
…Lao People’s Democratic Republic (PDR), Malaysia, Myanmar, Philippines, Singapore, Thailand and Viet Nam as they look to meet rising energy demand in a secure, affordable and sustainable manner. Key findings The growing weight of Southeast Asia Any assessment of the outlook for global energy has to reckon with the growing weight of Southeast Asia. Home to nearly one-in-ten of the world’s population, the rapidly growing economies of the region are shaping many aspects of the global economic and energy outlook.Southeast Asia is a very diverse and dynamic region, but one common element is that policy…

Southeast Asia Energy Outlook 2022
…Cambodia, Indonesia, Lao People’s Democratic Republic (Lao PDR), Malaysia, Myanmar, the Philippines, Singapore, Thailand and Viet Nam.Since the last edition of this report, the energy prospects for Southeast Asia have been affected by the Covid-19 pandemic, new energy and climate policy commitments and, most recently, high and volatile prices exacerbated by the Russian Federation’s (hereafter, “Russia”) invasion of Ukraine. Covid-19 led to a major economic shock for countries in Southeast Asia and the economic recovery now risks being slowed by higher energy prices. In the run up to the UN Climate Change Conference (COP26) in…

Climate Impacts on South and Southeast Asian Hydropower
Hydropower accounts for 14.5% of total electricity generation in South and Southeast Asia, with a total hydropower installed capacity of 117 GW. The installed hydropower capacity is expected to grow further in order to meet the region’s growing electricity demand and electricity export opportunities, and to maximise the merits of a cost-effective and flexible low-carbon power source. However, climate change poses an increasing challenge to South and Southeast Asian hydropower with rising temperatures, extreme rainfall patterns, melting glaciers, and increasing occurrence of extreme weather events.This report aims to support South and Southeast Asian hydropower in…

Efficient Grid-Interactive Buildings
Future of buildings in ASEAN A future with net zero emissions requires scaling up improvements in energy efficiency, electrification of end uses and renewable energy generation. For the Association of Southeast Asian Nations (ASEAN), a growing population and rising standards of living will massively increase future energy demand. Mitigating growing electricity demand and integrating renewable energy into electricity generation will therefore be paramount for the region’s clean energy transition and avoid lock-in of additional fossil fuel generation. The intermittent nature of variable renewable energy and increasing deployment of distributed energy resources are putting additional pressure on existing grids…

Decarbonisation Pathways for Southeast Asia
G7 report The International Energy Agency (IEA) and the Institute of Energy Economic, Japan (IEEJ) have developed and published long-term decarbonisation pathways for Southeast Asia and Indonesia. This paper provides a comparison of modelling approaches, quantitative drivers, and results from the IEA and IEEJ pathways, highlighting areas of agreement, as well as identifying and explaining differences, and thereby to derive implications. The IEA pathway used in the comparison is the Announced Pledges Scenario (APS) from the World Energy Outlook 2022 and the Energy Sector Roadmap to Net Zero Emissions in Indonesia. The IEEJ pathway is the net zero CO2…

Implementing Clean Energy Transitions
Focus on road transport in emerging economies This report assesses the impact of the road transport sector on energy demand, CO2 emissions and air pollution in several selected major emerging economies over the coming decades under several IEA modelling scenarios. Most notably the Announced Pledges Scenario (APS) aims to show to what extent announced ambitions and targets, including the most recent ones, are on the path to deliver emissions reductions required to achieve net zero emissions by 2050.Bringing about a road transport decarbonisation pathway in line with the APS in the selected major emerging economies - Brazil, People’s Republic…

Clean Energy Transitions Programme 2023
Annual report 2023 The Clean Energy Transitions Programme (CETP) is the IEA’s flagship initiative for accelerating progress toward a global net zero energy system. Launched at the 2017 IEA Ministerial to leverage the Agency’s expertise, insights and influence, the programme has provided world-class analysis, technical assistance and capacity building to support the most ambitious reorientation of the world’s energy systems this century. The CETP’s work is structured across three pillars of activity, with a particular focus on emerging markets and developing economies. The first of these focuses on supporting emerging and developing countries to establish…

Clean Energy Transitions Programme 2022
Annual report 2022 In the five years since its launch, the Clean Energy Transitions Programme (CETP) has become the largest and most important programme at the International Energy Agency (IEA). It has been the main vehicle through which the IEA has established, deepened and strengthened partnerships with major non-member countries – those countries that are at the forefront of the clean energy transition. The programme has also played a crucial role in enabling the IEA to strengthen its global leadership role in clean energy transitions at a pace and scale that would otherwise not have been possible, with great benefit…

Clean Energy Transitions Programme 2021
Annual report 2021 The Clean Energy Transitions Programme (CETP) has enabled the International Energy Agency (IEA) to significantly expand and deepen its global engagement and to support emerging economies’ transition to clean, resilient, sustainable energy systems. In 2021 the CETP marked its fourth full year since its launch at the 2017 IEA Ministerial Meeting, and the programme has steadily grown in size and impact.The CETP Annual Report 2021 aims to provide all CETP donors and partners with insights on the programme’s accomplishments, outputs and efforts across all areas of work. The report highlights activities and achievements for each…
