Therra is an EU-project funded by the Intelligent Energy Europe program. Its aim is to develop and disseminate a methodology for monitoring the total amount of renewable heat in the EU. Currently the definition of renewable heat is settled (e. g. heat pumps or waste), a major part of the renewable heat production (e. g. wood-stoves and solar collectors) is not directly measured and statistics for renewable heat vary per EU-country. The project is lead by SenterNovem from the Netherlands and Ademe (France), Adene (Portugal), AEA (Austria), BEA (Germany), CRES (Greece) and Kape (Poland) are participating in the project.

The aim of the ThERRA-project is to develop and disseminate a methodology for monitoring the total amount of renewable heat produced in the EU. The goal is that this methodology is acceptable for the key-actors in the EU and the participating countries and that it is tested in seven typical EU- countries.

The ThERRA-project runs from 2006 until the end of 2008. Most of the work is finished. The main results are an overview of the in the participating countries, an overview of monitoring projects and show cases, a draft methodology and a bench mark of the draft methodology.
