Bangladesh wants to sharply lower prices under a power purchase deal with India’s embattled Adani Group unless it is cancelled. The deal was signed in 2017 by Adani and a government entity under then prime minister Sheikh Hasina, who was ousted this year amid a popular uprising and accusations of widespread corruption. Supply from the 1,600-megawatt plant, which uses expensive imported coal, started last year and meets about a tenth of Bangladesh’s consumption.
