Integrated Energy Systems Planning is important to identify the role of different technologies in meeting their future energy needs. This includes analyzing the different technologies, elaborating sustainable energy strategies and conducting studies for energy system mix and electricity sector development and management, energy investment planning and energy environment policy formulation.

Countries in Asia and the Pacific are committed to the Sustainable Development Goals (SDGs) and their Nationally Determined Contributions (NDCs). Many have also set net-zero targets by mid-century. Since energy plays a critical role in achieving these, energy system analysis and planning must evolve to consider multidimensional factors. Supply and demand forecasting must now be balanced with adequacy and affordability, as well as sustainable energy production and consumption. The complexity in energy system planning is further enhanced by the increasing number of technologies and modalities in power generation, as well as by rapidly changing energy consumption patterns.

Integrated energy system planning enables the systematic analysis of factors to find optimal solutions in achieving energy, socio-economic, and climate goals. The IAEA promotes the use of several integrated modelling tools that can assist in defining optimal energy generation profiles, accounting for environmental and external costs, and calculating financial viability of energy projects, among others. ADB supports its developing member countries make more informed investment decisions and implement evidence-based policies by building their capabilities on these tools.


This Spotlight Session aims to introduce several integrated energy modelling tools that can support long-term energy planning compatible to overall national social development goals and climate targets.

    About the Organizer

    Asian Development Bank (ADB)

    The Asian Development Bank (ADB) is committed to achieving a prosperous, inclusive, resilient, and sustainable Asia and the Pacific, while sustaining its efforts to eradicate extreme poverty. It assists its members and partners by providing loans, technical assistance, grants, and equity investments to promote social and economic development.

    The International Atomic Energy Agency (IAEA)
    The International Atomic Energy Agency (IAEA) is an international organization that seeks to promote the peaceful use of nuclear energy, and to inhibit its use for any military purpose, including nuclear weapons. The IAEA was established as an autonomous organization on 29 July 1957. Though established independently of the United Nations through its own international treaty, the IAEA Statute, the IAEA reports to both the United Nations General Assembly and Security Council.

    Based in Vienna, the IAEA serves as an intergovernmental forum for scientific and technical co-operation on the peaceful use of nuclear technology and nuclear power worldwide. The programs of the IAEA encourage the development of the peaceful applications of nuclear energy, science, and technology, provide international safeguards against misuse of nuclear technology and nuclear materials, and promote nuclear safety (including radiation protection) and nuclear security standards and their implementation.
