New York, August 5, 2013 — GCube, the leading provider of renewable energy insurance services has published a report summarizing the most common wind energy insurance claims made in the United States.
The data based on 2012 US reported claims, shows that blade damage and gearbox failure account for the greatest number of losses – accounting for 41.4% and 35.1% of the total claims reported.
Meanwhile, damage to generators (10.2%) and transformers (5.1%) ranked third and fourth with damaged to foundations coming in fifth.
Commensurately, the top two most frequently reported causes of loss were cited as poor maintenance (24.5%) and lightning strikes (23.4%). Design defect (11.5%), wear and tear (9.3%) and mechanical defect (6.2%) featured in third, fourth and fifth when it came to assessing and understanding the reason cited for the initial claim.
Industry standards define a ‘design defect’ as a fault that is inherent in the design of the product itself. A ‘mechanical defect’ is a more generic term for a mechanical flaw and/or malfunction. This includes but is not limited to a material defect that would prevent the equipment from functioning as designed; such as metal fatigue, failure and blade delamination.
Although the majority of wind turbine blade damage can be attributed to lightning strikes; delamination and improper handling during the construction and installation phase are also frequent and need to be addressed.
Poor maintenance contributes significantly to the leading cause of gearbox failure with design defect factoring into loss frequency as well.
According to the independent analysis, gearbox claims typically cost the industry $380,000, while turbine blade claims cost on average of $240,000
per claim. Claims associated with the wind turbine foundations are typically higher, averaging $1,300,000 and have risen to $2,500,000 in exceptional circumstances throughout the 2012 period.
The average claim cost for repair or replacement includes business interruption and all other related fees and expenses before the insured’s deductible has been applied.
“We will continue to share our claims data and analysis in order to educate our insureds and the US wind energy industry in order to support efforts that improve reliability and maintenance practices within the community. We understand and appreciate the need to reduce the overall cost basis for operating a wind farm and believe that our data highlights the need for condition based monitoring and other proactive measures.” said John McLane, President, GCube Insurance Services Inc. “That monitoring is especially critical for turbine gearboxes as that component experiences the greatest engineering stress and up tower repair considerations.”
“While the industry can do little to reduce the risk of lightning strikes, we are pleased to see some of our insured working with manufactures and O&M providers to add blade assurance programs to their maintenance agreements that cover the repair or replacement of a blade damaged by lightning in light of the frequency of this natural occurrence.” McLane states further.
Since 2008, GCube has paid out over $200,000,000 in claims to the renewable energy industry, with the majority of this figure coming from the wind sector. As a result of GCube’s long established history and leadership position in the industry, this amount far exceeds that of any other insurer in the renewable energy space.

A product of ACORE's Transportation Initiative, the Transportation Industry Review is a digest of member-submitted journal articles laying out the challenges and corresponding opportunities that businesses and industry groups face in advancing and enlarging the market for renewable energy in the transportation sector.
Articles in the Review cover a wide range of topics, including electric vehicle policy and deployment; increasing biofuels production; electrification in heavy transportation; energy efficiency and current fuel economy standards; and many more. A total of eight different issues from prominent authors/organizations in the transportation and renewable energy sectors are addressed.
Authors and topics include:
- Volvo: "Can Electric Power Transport Goods as Well as People?"
- POET: "The Roadmap to 36 Billion Gallons of Biofuel"
- Covington & Burling LLP: "Reducing Costs and Overcoming Range Anxiety - Two Partial Bridges to the Future for EVs"
- California Fuel Cell Partnership: "Deploying Fuel Cell Electric Vehicles and Hydrogen in California"
- Sterling Planet: "Building the Infrastructure for Electric Vehicle Charging and Renewable Energy Production"
- Pacific Biodiesel: "The State of the Biodiesel Industry and Biodiesel's Role in the Renewable Fuel Portfolio"
- Professional Engineers in California Government: "Increasing the Market for EVs"
- Firestar Technologies: "Analysis on Vehicle Fuel Economy Improvements Serving Bridge to Zero Emission Vehicles"
ACORE's Transportation Initiative brings together leaders within the transportation and renewable energy industries from across all modes of transportation and sources of energy with the goal of creating a 21st century, multi-modal transportation system sourced by renewable energy and fuels. The Initiative and the Review are sponsored by Volvo and Amtrak.
