# Commission Implementing Decision (EU) 2017/1442 of 31 July 2017 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for large combustion plants (notified under document C(2017) 5225) (Text with EEA relevance), Division 5.1.2: Energy efficiency

Extent: E+W+S+N.I.

Table 33
BAT-associated energy efficiency levels (BAT-AEELs) for the combustion of process fuels from the chemical industry in boilers
These BAT-AEELs do not apply to units operated < 1 500 h/yr.
In the case of CHP units, only one of the two BAT-AEELs ‘Net electrical efficiency’ or ‘Net total fuel utilisation’ applies, depending on the CHP unit design (i.e. either more oriented towards generation electricity or towards heat generation).
These BAT-AEELs may not be achievable if the potential heat demand is too low.
These BAT-AEELs do not apply to plants generating only electricity.
