Chemplast Sanmar to acquire 27% in 37.5 MW solar developer

Chemplast Sanmar Limited

plans to buy a 27% stake in Yesaryes Energy Private Limited. The deal gives it access to power from a 37.5 MW solar project under a group captive model. What happened: The company filed the details with the exchanges on 10 October 2026 under Regulation 30. The aim is to cut its electricity cost by buying solar power at a tariff below grid rates. My data does not give the investment amount, the tariff or the share of the company’s power use this would cover. Why it matters: Power is a large cost for PVC and speciality chemical makers. A long-term solar supply can fix part of that cost and make it easier to predict. The stake is also a direct tie to the plant, since a captive structure usually needs the buyer to hold equity in the generator. My view: The logic is sound, but the size looks small. A 37.5 MW plant is modest for a chemical producer, and I cannot tell how much of its demand it would meet. A stake of 27% is just above the 26% minimum that captive status commonly needs, so the figure is probably set by that rule. That is my reading, not a stated reason. Savings depend on the tariff against grid power, on the charges the state may apply on captive supply, and on when the plant starts. Your data hints the plant is not yet running, but does not say so. Until there is a cost, tariff and start date, margin gains are only a hope. What I am watching: The investment amount, the commissioning date, and any change in power cost per unit in coming quarterly results.
