The "Ordinance on disposable loads", or "AbLaV" for short, existed from its adoption in 2012 until its repeal on July 1, 2022 and regulated the use of controllable, i.e. also disposable, electricity consumers (so-called "loads") in industry. The aim of such control was to stabilize the transmission grids.
The prequalified plants mainly included industrial companies with electricity-intensive processes that could be switched off or throttled back at short notice.
A basic distinction was made between loads that can be switched off quickly ("SNL"; activation within 15 minutes) and loads that can be switched off immediately ("SOL"; activation within 350 milliseconds).
