Disclosure Deadlines Overview: What Are Disclosure Deadlines for Renewable Energy?
Every European electricity supplier must disclose where their electricity originates from, using Guarantees of Origin to do so.
Backing renewable claims requires retiring GOs against actual consumption, and the disclosure deadline is the date by which those cancellations must have been executed in order for them to to count for the previous year's fuel mix.
Missing the disclosure deadline, therefore, will void any attempted claim entirely for that reporting period; the window is closed, and what wasn't cancelled in time cannot be used for it. For most of Europe, the cut-off falls on 31 March of the year following consumption. But "most" is doing rather heavy lifting in that sentence, because the exceptions are where things get quite operationally messy and punishing - Below we will provide an overview of European disclosure deadlines, highlighting any countries that differ from the norm.
What happens if you miss a GO disclosure deadline?
Once the cancellation window closes, uncancelled GOs either expire or roll forward into the next disclosure year. If a GO is cancelled after the deadline, it is still a valid cancellation, but invalid for that disclosure period. The accounting time-frame changes altogether.
Which countries have non-standard GO disclosure deadlines?
Tracking the divergences across AIB member domains reveals 5 markets operating outside the long-standing 31 March convention. Operating across these markets means tracking the full weight of different deadlines alongside their interactions with GO lifetimes and cancellation grace periods. Every reviewed domain is mapped below:
