From Peru:
The value of the energy content of methane (ct_ch4_nrg) was changed from 10 to 11 kWh/Nm3 (55.5 MJ/kgCH4 or 39,819 MJ/m3CH4 ), considering the higher heating value (HHV) instead of the lower heating value (LHV). In Germany we usually consider the lower heating value of 10 kWh/Nm3 (50,013 MJ/kgCH4 or 35,883 MJ/m3CH4 ).
