This study focused on evaluating the performance of biogas plants among the different district of Chhattisgarh State. Data from an existing biogas plants, located in Chhattisgarh state, was used for the performance evaluation of randomly selected biogas plants. Overall district wise biogas generation efficiency of Chhattisgarh plain was found to be 75.73 % and the efficiency was found maximum in district Mahasamund (83.50 %) and Durg (80.81 %) whereas minimum in district Raigarh (71.7 %). Average consumption or say use of biogas burner in the Chhattisgarh plains was found to be 3.75 h / day. However, the burner use-time varied with owner to owner from 2.70 h to 6.04 h /day. The district wise overall plant efficiency of Chhattisgarh plains was found 64.72 %, which varied district to district from 46-82 %. Overall performance was found maximum of 2 m3 plant (73.44 %) followed by 3 m3 (64.85 %). Minimum overall performance was found 8 m3 size (40.87 %) followed by 4m3 (44.62 %) size of plant. The overall plant efficiency reduced with increasing the plant size.
