New Delhi: Billionaire Tulsi Tanti-led Suzlon Energy said on Sunday that only few of the windmill blades made by it have cracked, but it is strengthening all in the category as a “proactive” measure.
Suzlon, the country’s top and world’s fifth largest windmill maker, has come under attack by the international media after one of its customers, Edison Mission Energy of the US, disclosed splitting of some windmill blades it had purchased from the Indian firm.
Having already allocated Rs 100 crore ($25 million) toward repair or replacement of all 1,251 blades from the category of those having cracked, Suzlon said it is “implementing a simple yet effective solution of strengthening the limited affected area of each blade”.
When asked whether similar problems have been reported by other clients, Suzlon Energy told PTI in a statement that “the cracks have been observed in 45 (single blades) of one particular version of these blades... of that version, 1,251 blades have been manufactured, of which 942 have been supplied to the US and 303 to Europe and Brazil.” “We do not anticipate that the cracking issue would affect all blades even without the retrofit (a programme to resolve the issue discovered at some of its S88 turbines in the US),” the statement said. However, all the blades of this type are being strengthened as a proactive and preventive measure to safeguard the customer interest, it added.
Edison Mission Energy said it expected Suzlon to pay certain unavailability damages and those related to the delays. The company had purchased 475 of 2.1-MW Model S88 wind turbines from Suzlon.
While noting that rotor blade cracks were identified on certain of the Suzlon S88 wind turbines, Edison said that the company was discussing a remediation plan for these blades, which is expected to include repairing or replacing all Model S88 blades at these projects.
