The insured sought summary judgment declaring that an all‑risk property and business interruption insurance policy covered losses arising from the preventive shutdown and repair of a hydroelectric penstock after a similar penstock failed due to defective welding.
The insurer had indemnified losses from the failed penstock but denied coverage for preventive repairs and business interruption relating to the second penstock.
The court held that the policy excluded the cost of rectifying defects in workmanship and that no insured loss had yet occurred because the second penstock had not suffered physical damage.
The court also rejected reliance on statutory mitigation obligations and the doctrine of imminent peril, finding the risk of failure was foreseeable but not inevitable.
The insurer’s cross‑motion for summary judgment was granted and the action dismissed.
