Technology Collaboration Programme

Advancing the research, development and commercialisation of energy technologies

The IEA Technology Collaboration Programme supports the work of 38 independent, international groups of experts that enable governments and industries from around the world to lead programmes and projects on a wide range of energy technologies and related issues.

More about collaboration on

Ocean Energy Systems (OES)

The OES TCP connects organisations and individuals working in the ocean energy sector to accelerate the viability, uptake and acceptance of ocean energy systems in an environmentally acceptable manner. The work of the OES TCP covers all forms of energy generation in which sea water forms the motive power through its physical and chemical properties i.e. wave, tidal range, tidal and ocean currents, ocean thermal energy conversion and salinity gradients.

Main areas of work

  • Assessment of environmental effects and monitoring efforts for ocean wave, tidal and current energy systems
  • Cost of energy assessment for wave, tidal, and ocean thermal energy conversion (OTEC) at an international level
  • Performance metrics international framework for ocean energy
  • Wave and tidal current energy numerical modelling

Key activities and accomplishments (2017-18)

Priorities and projects (2019-20)

  • Assessment of environmental effects and monitoring efforts for  wave, tidal and current energy systems 
  • Analysis and forecasts of the cost of ocean energy converters
  • Assessment on jobs creation in ocean energy
  • Ocean energy in insular conditions

Multilateral collaborations

  • Sponsorship of the International Network on Offshore Renewable Energy (INORE)
  • Collaboration with the TCP on Wind Energy
  • Collaboration with the OECD on jobs assessment for ocean energy
  • Collaboration with the International Conference on Ocean Energy (ICOE)


Why should your organisation become a member of OES?

The OES TCP facilitates:

  • access to advanced R&D teams in participating countries;
  • development of a harmonised set of measures and protocols for the testing of prototypes;
  • reduction of national costs by collaborating internationally;
  • creation of valuable international contacts between government, industry and science.

Through regular meetings, each member provides a well established platform where high-profile ocean energy issues can be addressed by experts and officials close to government policy making in each member country.
