Walloon green certificates – Frequently asked questions

Useful information about the sale of green certificates to Elia and Elia's payments to producers


Important change

Under the Transfer Decree adopted by the Walloon Parliament on 31 January 2019, which amends the Decree of 12 April 2001 on the organisation of the regional electricity market, the Walloon Public Service for Spatial Planning, Housing, Heritage and Energy took over the treatment of the files concerning green production since 1 May 2019. For the comprehension of the site, the term 'administrative authority' should be understood as referring to CWaPE before 30 April 2019 and the Walloon Public Service for Spatial Planning, Housing, Heritage and Energy from 1 May 2019 onwards.
