Biogas potential in Pakistan

There are 30,000 large farms in Pakistan employing more than 50 cattle and 18000 farms rearing 200 cattle per farm on the average. Large Farms and cattle owners can produce electricity for others and sell it to the grid. A farm having 1000 cattle can generate 0.5 MW of electricity and a farm of 2000 cattle can generate 1 MW. One can reasonably assume that 1000 such farms can be marshaled to provide atleast 1000 MW, against a total potential of 3800 MW.

Table: Biogas Potential in Pakistan

====================================================

No of Livestock=56.9 Million

Live stock Biomass generation=1 Mn Tons/day

Number of Large Dairy Farms=30,000 (avg 200 Cattles)

MSW =55000 tons/day

Crop residue= 225000 tons/day

Annual Biogas (Bio-methane) potential=1.6 TCF/yr

Pakistan Ngas Production=1.4 TCF/yr

Existing Short Fall= 1 TCF/yr

CNG consumption=0.164 TCF/yr

LNG projects =0.146 TCF/yr (25 Billion USD imports)

OR Electricity Potential from Biogas =3800 MW
