# 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 2.2.1: Energy efficiency

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

Table 8
BAT-associated energy efficiency levels (BAT-AEELs) for the combustion of solid biomass and/or peat
These BAT-AEELs do not apply in the case of 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).
The lower end of the range may correspond to cases where the achieved energy efficiency is negatively affected (up to four percentage points) by the type of cooling system used or the geographical location of the unit.
These levels may not be achievable if the potential heat demand is too low.
These BAT-AEELs do not apply to plants generating only electricity.
The lower end of the range may be down to 32 % in the case of units of < 150 MWth burning high-moisture biomass fuels.
