Systematic mistakes. Data has not been recorded on 11 January, 8-17 February 
and 22 February 2016 due to the systematic mistakes on PC. Temperature sensor

Substrates input. 3,732 tons of the solid substrates (2,474 tons in F1 and 1,258 in 
F2) and 
1,785.7 tons of liquid manure (1,211.5 in F1, 534.7 tons in F2 and 39.5 
tons in 2
nd
digester) have been fed into the digesters. There was no feeding into F2 
in July and August.

Biogas production. 919,947 Nm

biogas produced in total in 2016, among 
which, 59.3% produced in F1 (545,155 Nm

); 33.1% produced in F2 (304,588 
Nm

), and 4.4% has been burned through gas flare (40,829 Nm

). The overall 
biogas productivity is 1.34 Nm


Power generation and consumption. As recorded in BGA ULi, the total power 
generation is 1,673,173 kWh, while the Grid recorded it in 1,615,653 kWh, with 
57,520 kWh negative difference. Total power consumption of key electrical 
devices was 182,990 kWh in 2016. 

Heating supply. Excluding those mistaken values, the total heating supplied to 
biogas plant and the farm was approximately 167,440 kWh. Compare with 
electricity production, the heating supply efficiency is low in 2016, only 
accounting for 10% of the electrical energy. 

Temperature. Temperature in all sensors have been recorded incorrectly at -0.4 
ºC on 19-22 February due to systematic mistakes. Sensor 1 inside F1, Sensor 6 on 
F1 wall, Sensor 7 and Sensor 9 inside F2 were not functioning well, replacement 
or fix shall be conducted as soon as possible, Sensor 13 should be verified due to 
its big difference with Sensor 14 and 15. In generally, Temperature in F1 was 
ranging from 40-44 ºC at most of the time, it reached to 52.79 ºC at maximum 
during the summer time. Temperatures in F2 was ranging from 36-41 ºC at most 
of the time and recorded as normal temperature due to maintenance in July and 
August and few heating supplied. Temperature in 2
nd
digester was mostly stable at 
40-44 ºC, the highest temperature reached to 45.4 ºC in summer time.
