Petronet LNG and Gruner Form JV for Ten Compressed Biogas Plants
Petronet LNG and Gruner Renewable Energy have entered a joint venture to build 10 compressed biogas (CBG) plants in India, as reported by Autocar Professional and CNBC TV18 on 22 October 2026. CNBC TV18 reported the combined investment at Rs 1,200 crore. No further breakdown of individual plant values, locations or capacities was disclosed in the available reporting.
The partnership brings together Petronet LNG, one of India's major liquefied natural gas infrastructure companies, and Gruner Renewable Energy, a renewable energy firm, in a dedicated vehicle focused on CBG production. CBG, produced through the anaerobic digestion of organic waste and biomass, is treated as a substitute for compressed natural gas in transport and industrial applications.

Where the Biomass and CBG Pipeline Stands
The announcement comes as India's non-conventional power projects (biomass) pipeline continues to expand. Projects India tracks 152 live projects in this sub-sector, with 8 added in the last 90 days alone.
Of those 152 projects, the stage breakdown reveals a pipeline that is still heavily weighted towards early development. Sixty projects are currently under approvals, 24 are at the planning stage, and 12 have reached construction. A further 15 are on hold and 11 have been cancelled, while 24 are recorded as completed.
Geographically, Maharashtra leads with 29 tracked projects, followed by Karnataka with 18, Gujarat with 16, Andhra Pradesh with 14, Punjab with 12 and Madhya Pradesh with 11. This distribution reflects the concentration of agricultural biomass feedstock availability and state-level policy support across these regions.
Context Within India's Broader Biogas Activity
The Petronet LNG–Gruner venture is among the more sizeable private-sector moves in the CBG space to be publicly reported. The broader power projects sector has seen sustained interest in bioenergy, with recent coverage noting that the bioenergy sector was seen attracting Rs 2,800 crore at REI Expo 2026 according to the Indian Biogas Association. A separate contract for compressed biogas supply involving BPCL in Karnataka has also been tracked in recent months, pointing to growing downstream demand for CBG offtake.
Projects India currently records zero open tenders in the broader power projects sector, meaning procurement activity for the Petronet LNG–Gruner plants has not yet entered the public tender market based on available data.
What this means for suppliers and contractors
A ten-plant CBG programme represents potential procurement across civil construction, process equipment, feedstock handling systems, gas upgrading and compression units, and utility infrastructure. Suppliers and contractors active in biogas plant engineering, procurement and construction should monitor this joint venture for tendering activity as the programme moves from announcement towards project development.
The stage breakdown of the wider biomass pipeline — with 60 projects under approvals and 24 at planning — indicates that a substantial volume of future procurement is still to come to market. Maharashtra, Karnataka and Gujarat, which together account for 63 of the 152 tracked projects, represent the most active geographies for firms seeking early engagement with project developers.
Firms already tracking recent CBG contract awards such as the BPCL Karnataka project will be familiar with the equipment and service categories that are typically procured at this scale. The Petronet LNG–Gruner announcement, if it proceeds to construction across all ten sites, would represent a meaningful addition to the active construction count currently standing at just 12 projects nationally in this sub-sector.
Readers tracking developments in this space can monitor the full biomass project pipeline on Projects India for stage changes and new additions as the JV progresses.
