Onshore Wind Insurance & Risk Management

Describe more than the turbine rating

Build a schedule by turbine model, age, location, capacity and major component history. Include collection cables, substations, roads, control systems and spare equipment. The risk changes when a portfolio contains several turbine generations or components with limited support. Identify ownership of foundations and electrical infrastructure as carefully as ownership of nacelles and blades. PNNL describes both preventive and condition-based wind maintenance; records of what the operator actually does are more useful for underwriting than a statement that a service agreement exists.

Follow a component failure through repair

A gearbox, generator or blade loss can involve specialized transport, crane mobilization, seasonal access and a compatible replacement component. Review how property and machinery wording treats the damaged part, associated damage, dismantling, freight, installation and testing. An apparent repair option may be impractical if crane pads or access roads cannot support the required equipment. Record those constraints before setting a restoration period. Mechanical wear, warranty obligations and an insured breakdown are different concepts; ask the insurer to explain the applicable definitions and exclusions using the project equipment.

Review shared exposure and contracts

A single export transformer, collection circuit or control failure can affect multiple turbines. Determine the extent of concentration and whether shared equipment is included in declared values and interruption calculations. Compare the maintenance contract, availability undertaking and warranty remedy with the insurance policy. Contract penalties or an availability shortfall do not automatically satisfy a property damage trigger. Review indemnity, crane responsibility and care of customer property when outside service crews perform major exchanges. Confirm who bears transportation risk for removed and replacement components.

Consider a turbine whose damaged gearbox is available but cannot be installed until a suitable crane reaches the site. The equipment purchase price is only one part of the recovery. Compare crane availability, access preparation, mobilization and recommissioning with the interruption assumptions. Ask whether a shared spare can shorten downtime and whether its value and location are declared. This exercise can reveal why an otherwise adequate property limit leaves the business with an unexpected retained expense or a much longer outage.

Prepare the renewal evidence

A useful renewal file includes component exchanges, inspection trends, lightning and weather losses, corrective action, spare-parts strategy and current replacement values. Include OEM service status, maintenance responsibility and outstanding recommendations. Owners should identify lenders and loss payees and confirm the wording required by financing documents. Contractors should disclose work at height, rope access, lifting and electrical testing rather than using a broad maintenance description. Prioritize a documented failure-and-recovery scenario for the hardest-to-replace component; it can reveal both uninsured cost and an unrealistic recovery assumption.
