# 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 3.1.1: Energy efficiency

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

Table 13
BAT-associated energy efficiency levels (BAT-AEELs) for HFO and/or gas oil combustion 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 electricity generation or towards heat generation).
These levels may not be achievable if the potential heat demand is too low.
