High Efficiency Low Emissions Task Group (HELE)

Please visit the new Power page 

The High Efficiency Low Emissions Task Group (HELE) is a work stream dedicated to supporting energy efficiency improvements in conventional electricity generation. It addresses the potential of HELE technologies to lower emissions and contribute to a low carbon future. The task group focuses on:

  • Understanding and disseminating HELE technologies, such as Ultra Super Critical and Integrated Gasification Combined Cycle in power plants.
  • Developing and disseminating best practices in operation and maintenance.

HELE contributes to work under the G20 Energy Efficiency Leading Programme.

Why does the power sector matter for energy efficiency?

Membership and governance

Leading members: Japan.
Participants: Australia, China, Indonesia, Russia, South Africa and Turkey.

Recent developments

HELE has organised a number of workshops and site visits since its creation as the Global Superior Energy Performance (GSEP) Power Working Group. These workshops have brought together many G20 members, private sector leaders and international organisations including the International Energy Agency (IEA), the Organisation for Economic Co-operation and Development (the OECD), the Organization of the Petroleum Exporting Countries (OPEC) and the Asian Development Bank (ADB). In the past, the workshops have covered topics such as research, development, finance, and barriers to deployment of HELE technologies. HELE hosted two events in Turkey in 2015 as part of its activities under the G20 Energy Efficiency Action Plan.

Most recently, the task group organised a workshop on facilitating HELE technologies in Tokyo, Japan. The event focused on possible policy and finance measures to facilitate the development of HELE technologies and their introduction in countries that face challenges in deploying them. The workshop was followed by a site visit to two thermal power plants in Isogo and Yokohama, Japan.

The latest publications for this task group can be found on the Publications page.
