Regarding the charges against Adani & companions, they are accused of having bribed Indian officials to buy solar power at higher tariffs than the State Electricity Boards were willing to pay. Andhra Pradesh is specifically mentioned.
Here is the US District Attorney of East New York's indictment:

To prove this, IMO, the price at which power sold would have to be above market rates and improper selection of vendor based on the bids received from suppliers would have to be shown.
Here is a May 2020 paper analyzing costs and coming to the conclusion
"However, our analysis reveals that under current market conditions, tariffs below Rs2.50/kWh (US$ 3.47 cents/kWh) are financially unviable in the Indian solar sector today"

Here is a Feb 2021 news item regarding solar power tender bids in Andhra Pradesh:
https://www.newindianexpress.com/states ... 59891.html
The state government, which has invited tenders for 6,400 mega watts (MWs) of solar parks as a part of the 10,000 MW solar plants, has identified power at an average of Rs 2.49 per unit through reverse tendering. While the lowest bid is Rs 2.47 per unit for a 300 MW plant in Kambadur of Anantapur district, Rs 2.58 per unit is the highest.
According to a statement from the government on Thursday, Adani Renewable Energy Holding Twelve Ltd emerged as the lowest bidder for five 600 MW plants in M Kambaladinne (Kadapa), Pendlimarri (Kadapa), Rudrasamudram (Prakasam), CS Puram (Prakasam) and Mudigubba (Anantapur).
Kadapa-based Shirdi Sai Electricals was the lowest bidder for three 600 MW plants in Urichintla (Anantapur), Kambadur (Anantapur) and Kolimigundla (Kurnool), and one 400 MW plant proposed in Thondur (Kadapa).
Similarly, NTPC filed the lowest bid for the 600 MW plant proposed in Chakrayapet; HES Infra for a 600 MW plant; and Torrent Power for a 300 MW unit in Kambadur (Anantapur). As the matter is sub-judice, it is said that the awarding of the projects will be done after getting clearance from the High Court.
“The process has resulted in the government securing close to 14,000 million units of power per annum at a tariff of Rs 2.48 per kWh, which is significantly lower than the tariff at which AP distribution utilities are procuring power... This low tariff of Rs 2.48 per unit would result in savings of nearly Rs 3,800 crore in the very first year. These savings are likely to increase over the years, considering the fact the present tariff of Rs 2.48 per unit would remain constant over the next 30 years, whereas the cost associated with power from some of the other sources is likely to go up,” the statement from the Chief Minister’s Office on Thursday read.
Here is a January 2023 story
Andhra Pradesh To Buy 7,000 MW Solar Power from SECI at Rs 2.49 Per Unit
https://solarquarter.com/2023/01/18/and ... .49%2Funit.
The tie-up with Solar Energy Corporation of India, (SECI), for the supply of solar power is the most important. It will begin with 3,000 Megawatts (MW) from September 2024 in the first tranche and 3,000 MW and 1,000 MW in the second and third tranches from September 2025 and September 2026 respectively, Minister for Energy Peddireddi Ramachandra Reddy said on Monday.
The Minister chaired a review meeting and stated that the State government had made the bold decision to procure 7,000 MW from SECI at an effective price of Rs2.49/unit.
I do not know what to make of this. Maybe there are some other transactions of power sale between Adani and the Government of Andhra Pradesh that occurred at a higher price?

Where my biases lie - on general principles, I dislike billionaires as an "institution". They wield too much unelected and unaccountable power. Also, they have ample resources to defend themselves, so we need not exert ourselves. But I want to understand whether there is a genuine case of corruption here or is this ideological or economic warfare against Bharat = ideologically inspired in that hurting Adani might hurt Modi, or economic warfare in that disrupting a major player in the Indian market will slow down India's growth.
