Plenary sessions bring together the ACEF community to hear visionary and thought-provoking perspectives on key issues and opportunities from international thought leaders involved in regional cooperation and integration.

ACEF 2025 will have two plenary sessions: an Opening Plenary on "Power Trade Empowering the Region's Clean Energy Future" on Tuesday morning, and a Closing Plenary on "Regional Infrastructure Financing: Public Private Partnership and Private Sector Opportunity" on Friday afternoon.

The core of ACEF 2025 comprises four Thematic Tracks with speakers identified through the annual ACEF Call for Abstracts. Each track addresses specific actions needed to achieve the clean energy transition across Asia and the Pacific.

This year's Thematic Tracks include: Energy Efficiency and Sustainable Cooling, Regional Power Trade & Market Integration, Energy Access and Resilience, and Private Sector and Partnership Financing. These tracks explore innovations, policy frameworks, and financing mechanisms that can drive regional power trade, market integration, and sustainable development.

Deep Dive Workshops (DDWs) are marked by in-depth discussions of concepts, ideas, technologies, and business models. The format encourages interactive discussions and problem-solving.

DDWs are designed and organized by ADB in collaboration with its partner organizations and member countries. They may include cross-sectoral approaches (such as energy and water, energy and education, energy and cities, energy and transport) and other energy-related matters (such as regional cooperation, energy storage, energy efficiency, clean heating and cooling solutions, carbon capture utilization and storage, decentralized energy solutions, green hydrogen, climate adaptation of renewables, and smart energy technologies).

Operations Sessions present ADB's clean energy initiatives and experiences in various subregions of Asia and the Pacific—South, Central and West Asia; East and Southeast Asia; and the Pacific.

These sessions highlight project implementations, lessons learned, and operational strategies that have contributed to the advancement of clean energy solutions across different geographic and socioeconomic contexts within the region.

Spotlight Sessions highlight special emerging topics related to clean energy technologies, business models, and initiatives. They are organized by ADB and ACEF's co-organizers, governments and donors.

These sessions focus on innovative approaches, cutting-edge technologies, and novel financing mechanisms that have the potential to transform the clean energy landscape in the region.

ADB on the Ground is a fast-paced networking event that will be held on Monday 3 June and will showcase various ADB clean energy projects and initiatives.

ADB staff and their local and regional counterparts will deliver presentations to the broader clean energy community with the twin aims of (a) encouraging South-to-South learning across countries and departments, and (b) increasing awareness about transformative and innovative ADB interventions.

This session provides opportunities for participants to learn more about new technologies, approaches, and financing mechanisms that can accelerate a shift towards more sustainable, low-carbon energy sources and systems.

Pre-Forum Events provide an outlet for various organizations to discuss, brainstorm, and raise awareness about their clean energy initiatives or programs before the main ACEF sessions begin.
