Alternative Energy

A Shift in the Wind

As warranties run out on wind turbines, underwriters gain insight into their long-term costs.

Wind energy is all grown up. It is no longer an alternative, but in some wholesale markets has set the incremental cost of generation.

As the industry has grown, turbine towers have as well. And as the older ones roll out of their warranty periods, there are more claims.

This is a bit of a pinch in a soft market, but it gives underwriters new insight into performance over time — insight not available while manufacturers were repairing or replacing components.

“There is a lot of capacity in the wind market,” said Charles Long, area senior vice president for renewable energy at broker Arthur J. Gallagher.

“The segment is still very soft. What we are not seeing is any major change in forms from the major underwriters. They still have 280-page forms. The specialty underwriters have a 48-page form. The larger carriers need to get away from a standard form with multiple endorsements and move to a form designed for wind, or solar, or storage. It is starting to become apparent to the clients that the firms have not kept up with construction or operations,” at renewable energy facilities, he said.

Third-party liability also remains competitive, Long noted.

“The traditional markets are doing liability very well. There are opportunities for us to market to multiple carriers. There is a lot of generation out there, but the bulk of the writing is by a handful of insurers.”

Broadly the market is “still softish,” said Jatin Sharma, head of business development for specialty underwriter G-Cube.

“There has been an increase in some distressed areas, but there has also been some regional firming. Our focus is very much on the technical underwriting. We are also emphasizing standardization, clean contracts. That extends to business interruption, marine transit, and other covers.”

The Blade Problem

“Gear-box maintenance has been a significant issue for a long time, and now with bigger and bigger blades, leading-edge erosion has become a big topic,” said Sharma. “Others include cracking and lightning and even catastrophic blade loss.”

Long, at Gallagher, noted that operationally, gear boxes have been getting significantly better. “Now it is blades that have become a concern,” he said. “Problems include cracking, fraying, splitting.

“In response, operators are using more sophisticated inspection techniques, including flying drones. Those reduce the amount of climbing necessary, reducing risk to personnel as well.”

Underwriters certainly like that, and it is a huge cost saver to the owners, however, “we are not yet seeing that credited in the underwriting,” said Long.

He added that insurance is playing an important role in the development of renewable energy beyond the traditional property, casualty, and liability coverages.

“Most projects operate at lower capacity than anticipated. But they can purchase coverage for when the wind won’t blow or the sun won’t shine. Weather risk coverage can be done in multiple ways, or there can be an actual put, up to a fixed portion of capacity, plus or minus 20 percent, like a collar; a straight over/under.”

As useful as those financial instruments are, the first priority is to get power into the grid. And for that, Long anticipates “aggressive forward moves around storage. Spikes into the system are not good. Grid storage is not just a way of providing power when the wind is not blowing; it also acts as a shock absorber for times when the wind blows too hard. There are ebbs and flows in wind and solar so we really need that surge capacity.”

Long noted that there are some companies that are storage only.

“That is really what the utilities are seeking. The storage company becomes, in effect, just another generator. It has its own [power purchase agreement] and its own interconnect.”

Another trend is co-location, with wind and solar, as well as grid-storage or auxiliary generation, on the same site.

“Investors like it because it boosts internal rates of return on the equity side,” said Sharma. “But while it increases revenue, it also increases exposure. … You may have a $400 million wind farm, plus a $150 million solar array on the same substation.”

In the beginning, wind turbines did not generate much power, explained Rob Battenfield, senior vice president and head of downstream at JLT Specialty USA.

“As turbines developed, they got higher and higher, with bigger blades. They became more economically viable. There are still subsidies, and at present those subsidies drive the investment decisions.”

For example, some non-tax paying utilities are not eligible for the tax credits, so they don’t invest in new wind power. But once smaller companies or private investors have made use of the credits, the big utilities are likely to provide a ready secondary market for the builders to recoup their capital.

That structure also affects insurance. More PPAs mandate grid storage for intermittent generators such as wind and solar. State of the art for such storage is lithium-ion batteries, which have been prone to fires if damaged or if they malfunction.

“Grid storage is getting larger,” said Battenfield. “If you have variable generation you need to balance that. Most underwriters insure generation and storage together. Project leaders may need to have that because of non-recourse debt financing. On the other side, insurers may be syndicating the battery risk, but to the insured it is all together.”

There has also been a mechanical and maintenance evolution along the way. “The early-generation short turbines were throwing gears all the time,” said Battenfield.

But now, he said, with fewer manufacturers in play, “the blades, gears, nacelles, and generators are much more mechanically sound and much more standardized. Carriers are more willing to write that risk.”

There is also more operational and maintenance data now as warranties roll off. Battenfield suggested that the door started to open on that data three or four years ago, but it won’t stay open forever.

“When the equipment was under warranty, it would just be repaired or replaced by the manufacturer,” he said.

“Now there’s more equipment out of warranty, there are more claims. However, if the big utilities start to aggregate wind farms, claims are likely to drop again. That is because the utilities have large retentions, often about $5 million. Claims and premiums are likely to go down for wind equipment.”

Repair costs are also dropping, said Battenfield.

“An out-of-warranty blade set replacement can cost $300,000. But if it is repairable by a third party, it could cost as little as $30,000 to have a specialist in fiberglass do it in a few days.”

As that approach becomes more prevalent, business interruption (BI) coverage comes to the fore. Battenfield stressed that it is important for owners to understand their PPA obligations, as well as BI triggers and waiting periods.

“The BI challenge can be bigger than the property loss,” said Battenfield. “It is important that coverage dovetails into the operator’s contractual obligations.” &

The Profession

For This Pharmaceutical Risk Director, Managing Risk Means Being Part of the Mission to Save Lives

Meet Eric Dobkin, director, insurance and risk management, for Merck & Co. Inc.
By: | September 28, 2018 • 5 min read

R&I: What was your first job?
My first job out of undergrad was as an actuarial trainee at Chubb.I was a math major in school, and I think the options for a math major coming out are either a teacher or an actuary, right? Anyway, I was really happy when the opportunity at Chubb presented itself. Fantastic company. I learned a lot there.

R&I: How did you come to work in risk management?
After I went back to get my MBA, I decided I wanted to work in corporate finance. When I was interviewing, one of the opportunities was with Merck. I really liked their mission, and things worked out. Given my background, they thought a good starting job would be in Merck’s risk management group. I started there, rotated through other areas within Merck finance but ultimately came back to the Insurance & Risk Management group. I guess I’m just one of those people who enjoy this type of work.

R&I: What is risk management doing right?
I think the community is doing a good job of promoting education, sharing ideas and advancing knowledge. Opportunities like this help make us all better business partners. We can take these ideas and translate them into actionable solutions to help our companies.

R&I: What could the risk management community be doing a better job of?
I think we have made good advancements in articulating the value proposition of investing in risk management, but much more can be done. Sometimes there is such a focus on delivering immediate value, such as cost savings, that risk management does not get appropriate attention (until something happens). We need to develop better tools that can reinforce that risk management is value-creating and good for operational efficiency, customers and shareholders.

R&I: What’s been the biggest change in the risk management and insurance industry since you’ve been in it?
I’d actually say there hasn’t been as much change as I would have hoped. I think the industry speaks about innovation more often than it does it. To be fair, at Merck we do have key partners that are innovators, but some in the industry are less enthusiastic to consider new approaches. I think there is a real need to find new and relevant solutions for large, complex risks.

R&I: What emerging commercial risk most concerns you?
Cyber risk. While it’s not emerging anymore, it’s evolving, dynamic and deserves the attention it gets. Merck was an early adopter of risk transfer solutions for cyber risk, and we continue to see insurance as an important component of the overall cyber risk management framework. From my perspective, this risk, more than any other, demands continuous forward-thinking to ensure we evolve solutions.

R&I: What’s the biggest challenge you’ve faced in your career?
Sticking with the cyber theme, I’d say navigating through a cyber incident is right up there. In June 2017, Merck experienced a network cyber attack that led to a disruption of its worldwide operations, including manufacturing, research and sales. It was a very challenging environment. And managing the insurance claim that resulted has been extremely complex. But at the same time, I have learned a tremendous amount in terms of how to think about the risk, enterprise resiliency and how to manage through a cyber incident.

R&I: What advice might you give to students or other aspiring risk managers?
Have strong intellectual curiosity. Always be willing to listen and learn. Ask “why?” We deal with a lot of ambiguity in our business, and the more you seek to understand, the better you will be able to apply those learnings toward developing solutions that meet the evolving risk landscape and needs of the business.

R&I: What role does technology play in your company’s approach to risk management?
We’re continuing to look for ways to apply technology. For example, being able to extract and leverage data that resides in our systems to evaluate risk, drive efficiencies and make things like property-value reporting easier. We’re also looking to utilize data visualization tools to help gain insights into our risks.

R&I: What are your goals for the next five to 10 years of your career?
I think, at this time, I would like to continue to learn and grow in the type of work I do and broaden my scope of responsibilities. There are many opportunities to deliver value. I want to continue to focus on becoming a stronger business partner and help enable growth.

R&I: What is your favorite book or movie?
I’d say right now Star Wars is top on my list. It has been magical re-watching and re-living the series I watched as a kid through the eyes of my children.

R&I: What is the riskiest activity you ever engaged in? When I was about 15, I went to a New York Rangers versus Philadelphia Flyers game at the Philadelphia Spectrum. I wore my Rangers jersey. I would not do that again.

Eric Dobkin, director, insurance & risk management, Merck & Co. Inc

R&I: What is it about this work you find most fulfilling or rewarding?
I am passionate about Merck’s mission of saving and improving lives. “Inventing for Life” is Merck’s tagline. It’s funny, but most people don’t associate “inventing” with medicine. But Merck has been inventing medicines and vaccines for many of the world’s most challenging diseases for a long time. It’s amazing to think the products we make can help people fight terrible diseases like cancer. Whatever little bit I can do to help advance that mission is very fulfilling and rewarding.

R&I: What do your friends and family think you do?
Ha! My kids think I make medicine. I guess they think that because I work for Merck. I suppose if even in a small way I can contribute to Merck’s mission of saving and improving lives, I am good with that. &
