Lithium-Ion Batteries Strain Risk Management

The Fire Department of New York is concerned about grid storage safety.

New York City is agressively adding solar capacity. But the risks of energy storage must be addressed.

In September 2016, New York City committed to an ambitious program of solar energy and storage. The plan calls for 100 MWh of energy storage by 2020 and 1 GW of solar capacity by 2030. Photovoltaic technology is well established, but the lithium-ion (Li-ion) battery technology used to store the collected energy is much more fraught. Within weeks, the Fire Department of New York expressed concerns about retrofitting commercial- and industrial-scale batteries, called grid storage, into the density of the city.

In January 2017, underwriters with FM Global issued an 18-page data sheet with loss-prevention recommendations for Li-ion installations. Some specialty insurers have been willing to underwrite standalone Li-ion grid storage, others so far have only been willing to cover such installations as part of a broader property policy for a renewable-energy generation facility or power plant.

“We think we can come up with schemes that will provide reasonable levels of protection now and in the future.” — Gary Keith, vice president, engineering standards manager, FM Global.

Li-ion batteries power cell phones, tablet computers, and some electric cars. They are compact, dense, and represent the leading edge of storage efficiency. Those same characteristics make them prone to runaway overheating if there is a short or damage to a cell. There have been notorious examples of burning devices and even vehicles in recent years.

There have also been fires at grid storage installations. The most notable was a 2012 incident in Hawaii. A 15 MW grid storage array with 12,000 cells was destroyed by fire at the 30 MW Kahuku wind farm on Oahu.

Li-ion grid storage “in conjunction with wind or solar provides stability into the grid as well as peak performance,” said Charles Long, area supervisor for energy at brokerage Arthur J. Gallagher.

“For some underwriters, grid storage is literally too hot to handle. Others are willing to quote but very selectively. For a large utility the insurers will pick it up no worries, but for a phone-battery maker looking to move up to grid storage, they would find a lot of resistance in the market.”

Long emphasized that the big issue for grid storage is not the value of the battery but the potential for business interruption.

“The BI is usually significantly higher than the property. If a 200 to 300 MW wind farm loses its grid-storage, that may be $20 million to replace the battery but a $40 million BI loss if the power-purchase agreement mandates battery backup.”

Gary Keith, vice president engineering standards manager at FM Global, said that with the proliferation of microgrids and grid storage, it was important for his firm to issue the data sheet as soon as it could.

“We are going to see more and more mandates for this type of storage. Power generation is one aspect of the issue, but our motivation for the data sheet was usage expanding to independent power availability in commercial and industrial applications.”

There are two key points, Keith stressed.

“The fire hazard is from a short or damage that causes a runaway chemical reaction, not from the ambient heat of operation. Also, Li-ion is not lithium metal [which reacts violently with water]. We recommend sprinkler protection, and separation, at least 20 feet from any other structure or exposure.”

While the proliferation of microgrids and grid storage represents a clear emerging risk, “the technology is not outside current fire codes and practices,” said Keith at FM Global.

“We think we can come up with schemes that will provide reasonable levels of protection now and in the future.”

That future looks very big. According to the University of Michigan Center for Sustainable Systems, as of June 2016, the U.S. had more than 21.6 GW of rated power in energy storage compared to 1,068 GW of total in-service installed generation capacity. Globally, installed energy storage totaled 150 GW.

Only 2.5 percent of delivered electric power in the U.S. is cycled through a storage facility. For comparison, that figure is 10 percent in Europe and 15 percent in Japan. U.S. energy storage projects increased by 105 percent from 2013 to 2016. California leads with 149 operational projects (4.03 GW), followed by Virginia with 3.25 GW and Texas with 24 projects.

To the High Net Worth Homeowner: Build a Disaster Resiliency Plan You Can Be Proud Of

Having a resiliency plan and practicing it can make all the difference in a disaster.
By: | September 14, 2018 • 7 min read

Packed with state-of-the-art electronics, priceless collections and high-end furnishings, and situated in scenic, often remote locations, the dwellings of high net worth individuals and families pose particular challenges when it comes to disaster resiliency. But help is on the way.

Armed with loss data, innovative new programs, technological advances, and a growing army of niche service-providers aimed at addressing an astonishingly diverse set of risks, insurers are increasingly determined to not just insure against their high net worth clients’ losses, but to prevent them.

Insurers have long been proactive in risk mitigation, but increasingly, after the recent surge in wildfire and storm losses, insureds are now, too.

“Before, insurance was considered the only step in risk management. Now, our client families realize it is one of the many imperative steps in an effective risk management strategy,” said Laura Sherman, founding partner at Baldwin Krystyn Sherman Partners.

And especially in the high net worth space, preventing that loss is vastly preferable to a payout, for insurers and insureds alike.

“If insurers can preserve even one house that’s 10 or 20 or 40 million dollars … whatever they have spent in a year is money well spent. Plus they’ve saved this important asset for the client,” said Bruce Gendelman, chairman and founder Bruce Gendelman Insurance Services.

High Net Worth Vulnerabilities

As the number and size of luxury homes built in vulnerable areas has increased, so has the frequency and magnitude of extreme weather events, including hurricanes, harsh cold and winter storms, and wildfires.

“There is a growing desire to inhabit this riskier terrain,” said Jason Metzger, SVP Risk Management, PURE group of insurance companies. “In the western states alone, a little over a million homes are highly vulnerable to wildfires because of their proximity to forests that are fuller of fuel than they have been in years past.”

Such homes are often filled with expensive artwork and collections, from fine wine to rare books to couture to automobiles, each presenting unique challenges. The homes themselves present other vulnerabilities.

“Larger, more sophisticated homes are bristling with more technology than ever,” said Stephen Poux, SVP and head of Risk Management Services and Loss Prevention for AIG’s Private Client Group.

“A lightning strike can trash every electronic in the home.”

Niche Service Providers

A variety of niche service providers are stepping forward to help.

Secure facilities provide hurricane-proof, wildfire-proof off-site storage for artwork, antiques, and all manner of collectibles for seasonal or rotating storage, as well as ahead of impending disasters.

Other companies help manage such collections — a substantial challenge anytime, but especially during a crisis.

“Knowing where it is, is a huge part of mitigating the risk,” said Eric Kahan, founder of Collector Systems, a cloud-based collection management company that allows collectors to monitor their collections during loans to museums, transit between homes, or evacuation to secure storage.

“Before, insurance was considered the only step in risk management. Now, our client families realize it is one of the many imperative steps in an effective risk management strategy.” — Laura Sherman, founding partner, Baldwin Krystyn Sherman Partners

Insurers also employ specialists in-house. AIG employs four art curators who advise clients on how to protect and preserve their art collections.

Perhaps the best known and most striking example of this kind of direct insurer involvement are the fire teams insurers retain or employ to monitor fires and even spray retardant or water on threatened properties.

High-Level Service for High Net Worth

All high net worth carriers have programs that leverage expertise, loss data, and relationships with vendors to help clients avoid and recover from losses, employing the highest levels of customer service to accomplish this as unobtrusively as possible.

“What allows you to do your job best is when you develop that relationship with a client, where it’s the same people that are interacting with them on every front for their risk management,” said Steve Bitterman, chief risk services officer for Vault Insurance.

Site visits are an essential first step, allowing insurers to assess risks, make recommendations to reduce them, and establish plans in the event of a disaster.

“When you’re in a catastrophic situation, it’s high stress, time is of the essence, and people forget things,” said Sherman. “Having a written plan in place is paramount to success.”

Another important component is knowing who will execute that plan in homes that are often unoccupied.

Domestic staff may lack the knowledge or authority to protect the homeowner’s assets, and during a disaster may be distracted dealing with threats to their own homes and families. Adequate planning includes ensuring that whoever is responsible has the training and authority to execute the plan.

Evaluating New Technology

Insurers use technologies like GPS and satellite imagery to determine which homes are directly threatened by storms or wildfires. They also assess and vet technologies that can be implemented by homeowners, from impact glass to alarm and monitoring systems, to more obscure but potentially more important options.

AIG’s Poux recommends two types of vents that mitigate important, and unexpected risks.

“There’s a fantastic technology called Smart Vent, which allows water to flow in and out of the foundation,” Poux said. “… The weight of water outside a foundation can push a foundation wall in. If you equalize that water inside and out at the same level, you negate that.”

Another wildfire risk — embers getting sucked into the attic — is, according to Poux, “typically the greatest cause of the destruction of homes.” But, he said, “Special ember-resisting venting, like Brandguard Vents, can remove that exposure altogether.”

Building Smart

Many disaster resiliency technologies can be applied at any time, but often the cost is fractional if implemented during initial construction. AIG’s Smart Build is a free program for new or remodeled homes that evolved out of AIG’s construction insurance programs.

Previously available only to homes valued at $5 million and up, Smart Build recently expanded to include homes of $1 million and up. Roughly 100 homes are enrolled, with an average value of $13 million.

“In the high net worth space, sometimes it takes longer potentially to recover, simply because there are limited contractors available to do specialty work.” — Curt Goetsch, head of underwriting, Private Client Group, Ironshore

“We know what goes wrong in high net worth homes,” said Poux, citing AIG’s decades of loss data.

“We’re incenting our client and by proxy their builder, their architects and their broker, to give us a seat at the design table. … That enables us to help tweak the architectural plans in ways that are very easy to do with a pencil, as opposed to after a home is built.”

Poux cites a remote ranch property in Texas.

“The client was rebuilding a home but also installing new roads and grading and driveways. … The property was very far from the fire department and there wasn’t any available water on the property.”

Poux’s team was able to recommend underground water storage tanks, something that would have been prohibitively expensive after construction.

“But if the ground is open and you’ve got heavy equipment, it’s a relatively minor additional expense.”

Homes that graduate from the Smart Build program may be eligible for preferred pricing due to their added resilience, Poux said.

Recovery from Loss

A major component of disaster resiliency is still recovery from loss, and preparation is key to the prompt service expected by homeowners paying six- or seven-figure premiums.

Before Irma, PURE sent contact information for pre-assigned claim adjusters to insureds in the storm’s direct path.

“In the high net worth space, sometimes it takes longer potentially to recover, simply because there are limited contractors available to do specialty work,” said Curt Goetsch, head of underwriting for Ironshore’s Private Client Group.

“If you’ve got custom construction or imported materials in your house, you’re not going to go down the street and just find somebody that can do that kind of work, or has those materials in stock.”

In the wake of disaster, even basic services can be scarce.

“Our claims and risk management departments have to work together in advance of the storm,” said Bitterman, “to have contractors and restoration companies and tarp and board services that are going to respond to our company’s clients, that will commit resources to us.”

And while local agents’ connections can be invaluable, Goetsch sees insurers taking more of that responsibility from the agent, to at least get the claim started.

“When there is a disaster, the agency’s staff may have to deal with personal losses,” Goetsch said. &
