What factors affect biogas plant cost?

Plant capacity and daily feedstock volume
Level of automation (manual vs fully automatic feeding)
Type of digester (fixed-dome, floating-drum, prefabricated)
Gas upgrading needs (raw biogas vs Bio-CNG)

Is a biogas plant a good investment?

Yes. Institutional plants often pay back within 16–20 months through savings on LPG, electricity, and waste-disposal fees, plus revenue from organic manure. Government subsidies can further reduce the upfront cost — see our guide on biogas subsidies in India.

Are there subsidies for biogas plants in India?

Yes. Central and state schemes such as the National Bioenergy Programme offer capital subsidies for qualifying biogas plants. Eligibility depends on plant size and category.
