RETD (2005-2017)

The IEA Renewable Energy Technology Deployment (RETD) Technology Collaboration Programme was officially launched in September 2005 and ended on July 2017. The RETD’s mandate was to address cross-cutting issues that influence the deployment of renewable energy and to act as a vehicle to accelerate the market introduction and deployment of renewable energy technologies.

While the other IEA Technology Collaboration Programmes on renewable energy focus on specific technologies, the RETD was cross-cutting from a technological point of view and complemented the activities of the other TCPs.
