Ambani puts a ₹1 trillion compressed-biogas plan on the table in Andhra Pradesh

Anant Ambani said Reliance Industries plans to invest ₹1 trillion in compressed biogas projects in Andhra Pradesh, a figure he tied to more than 3 lakh jobs and about ₹60,000 crore in revenue for the state over the coming decades.

He was speaking on Friday at the foundation-stone ceremony for the Rayalaseema Horticulture Hub and the Indian School of Agriculture in Madanapalle. The investment, he said, would support the state's clean-energy plans, create work, and add to its energy infrastructure. The jobs he named sit along the chain: feedstock cultivation, plant operations, transport and the services around them.

The ₹1 trillion figure is a plan, not a spent sum. Reliance already has a smaller programme on the ground in the same state. In April 2025 the company began work on the first of a planned 500 compressed biogas plants under an earlier commitment of ₹65,000 crore. Five hundred plants at that budget is ₹130 crore a plant if the money is spread evenly, which it will not be. The new ₹1 trillion line is more than fifteen times that earlier programme. Ambani did not say on Friday how many plants the larger sum implies, or over how many years the capital would be committed.

He also set the Reliance plan inside a state number that is larger still. Since June 2024, he said, the Andhra Pradesh government had approved 388 mega projects with investment commitments of more than ₹14 trillion, and a jobs claim of nearly 11 lakh. Those are approvals and commitments, the same category as his own announcement. A commitment becomes a plant when land, feedstock contracts and a grid connection are in place. Andhra has been collecting announcements under a banner it calls Speed of Doing Business. The test of that banner is how many of the 388 have started civil work.

Compressed biogas is methane taken off crop residue, cattle dung and other organic waste, cleaned, and compressed for use as a transport fuel or as a substitute for natural gas. The plant is the visible part. The harder part in a state like Andhra is the daily supply of feedstock within a short radius, because the gas is not worth moving as waste. A ₹1 trillion programme that does not lock in farmers within trucking distance of each site will have plants and no input. Ambani pointed at agriculture and feedstock cultivation as part of the job count. That is the right place to look. It is also the place where announcements usually thin out.

The revenue figure of ₹60,000 crore for the state is a multi-decade claim. It was not broken into tax, royalty and power purchases. Spread over 20 years it is ₹3,000 crore a year. Spread over 40 years it is half that. Without the period and the tax base, the number cannot be checked against a budget. It can be checked later against whatever the commercial taxes department actually books from these plants.

Madanapalle was an odd stage for an energy announcement and a logical one for a feedstock announcement. The horticulture hub and the agricultural school are about what the Rayalaseema districts grow. Residue from that farming is the raw material a biogas plant needs. If the ₹1 trillion plan has a first district, the ceremony suggested it is this one. Reliance has not published a site list for the new tranche.

What can be watched in the next quarter is narrower than the speech. Does a second plant follow the one started in April 2025. Does the company file a project list with the state investment promotion body that adds up toward ₹1 trillion. Do the 3 lakh jobs appear as anything other than a line in a press note. The April programme of 500 plants and ₹65,000 crore is the baseline. Friday's number is the claim that baseline is about to be multiplied.
