Off the New York coastline would be a perfect place for an array of wind turbines, according to a Stanford professor. It would not only offer clean energy to the Big Apple but it would protect it the next time a Superstorm Sandy comes calling.

“If you have a large enough array of wind turbines, you can prevent the wind speeds [of a hurricane] from ever getting up to the destructive wind speeds,” said Mark Jacobson, a professor of civil and environmental engineering at Stanford University.

Computer models demonstrated that offshore wind turbines reduce peak wind speeds in hurricanes by up to 92 mph and decrease storm surge by up to 79 percent, said Jacobson, who worked on the study with University of Delaware researchers Cristina Archer and Willett Kempton.

“The additional benefits are there is zero cost unlike seawalls, which would cost about $30 billion,” he said, noting that the wind turbines “generate electricity so they pay for themselves.”

The researchers studied three hurricanes, Sandy and Isaac, which struck New York and New Orleans, respectively, in 2012; and Katrina, which slammed into New Orleans in 2005. Generally, 70 percent of damage is caused by storm surge, with wind causing the remaining 30 percent, he said.

That’s why onshore wind farms would not be as effective, he said. While they would reduce the wind speed, they wouldn’t impact storm surge.

In 2013, one of the “most inactive” Atlantic hurricane seasons on record, insured losses totaled $920 million, according to Guy Carpenter, which relied on information from the Mexican Association of Insurance Institutions. The most noteworthy events were Hurricane Ingrid in the Atlantic and Tropical Storm Manuel in the Pacific, which displaced thousands as they caused excessive rainfall, flooding and mudslides.

According to the Insurance Information Institute, Katrina was the costliest hurricane in insurance history, at $48.7 billion, followed by Andrew in 1992 at $25.6 billion and Sandy at $18.8 billion. Economic losses, of course, were much higher.

Wind turbines, which can withstand speeds of up to 112 mph, dissipate the hurricane winds from the outside-in, according to Jacobson’s study. First, they slow down the outer rotation winds, which feeds back to decrease wave height. That reduces the movement of air toward the center of the hurricane, and increases the central pressure, which in turn slows the winds of the entire hurricane and dissipates it faster.

The benefit would occur whether the turbines were immediately upstream of a city, or along an expanse of coastline. It could take anywhere from tens of thousands to hundreds of thousands of wind turbines off the coast to offer sufficient hurricane protection.

At present, there are no wind farms off the U.S. coastline, although 18 have been proposed for off the East Coast. Proposals have also been made for off the West Coast and the Great Lakes. There are 25 operational wind farms off the coast of Europe.

“Overall,” Jacobson and his colleagues concluded in the study, “we find here that large arrays of electricity-generating offshore wind turbines may diminish hurricane risk cost-effectively while reducing air pollution and global warming, and providing local or regionally sourced energy supply.”

A Possible New Market

Regulators have decided they can't risk electricity shortfalls. A new insurance market may result.
By: | November 2, 2015 • 6 min read

Government regulation is often portrayed as the bane of free markets, but in the case of new rules governing electrical power generation in the Northeast and Midwest, regulation is actually creating a new and specialized insurance market.

After a series of electricity shortfalls over the past few years, two regional power wholesale organizations in the eastern U.S. now have federal approval to institute a system under which generators that fail to provide the power they have promised at peak times will pay for the cost of replacement power. In one interesting twist, it is not so much the risk that is emerging, but rather the risk-transfer market itself.

Last year, ISO-New England (ISO-NE) got approval from the Federal Energy Regulatory Commission (FERC) to institute a system of charges and payments. In July of this year, PJM, the regional transmission operator for a wide swath of the Middle Atlantic and eastern Midwest, also got FERC approval for a similar system.

The United States and Canada are divided into regional independent system operators (ISOs) and regional transmission organizations (RTOs), which differ only in a few legal senses.

It is straight cost of replacement for non-delivered goods, in this case, electricity.” — Matthew White, chief economist at ISO-NE

At present, ISO-NE and PJM are mandatory markets, where all power providers must participate and mandatory charges are in place. Others are voluntary.

Utility industry organizations note that pending federal legislation could recognize the preferability of mandatory participation and payment systems, but that is a long way from being passed and signed into law.

Even though the ISO-NE and PJM regimes were approved at different times, they both go into effect with the delivery contracts starting in June 2018. Those contracts have already been bid and accepted, and in most cases power generators have already figured the costs into their rates.

The purpose for the new rules is to ensure sufficient power at peak demand, especially during hot summer days and winter storms. The charge-and-payment system is a double-settlement contract, standard in commodity markets.

If a supplier fails to provide the commodity — grain, oil, power — in the agreed amount at the agreed time, the supplier has to pay a set compensation, which the buyer then uses to fill the gap on the spot market. It is a straight transfer to ensure delivery.

“These are fully insurable risks,” said Matthew White, chief economist at ISO-NE.

“It is straight cost of replacement for non-delivered goods, in this case, electricity. Insurance is a critical part of our ability to deliver power, and we considered the insurability of the risk in market design whenever we make significant changes.”

It is also important to note that the core purpose of the new regimes is to encourage generators to invest in their infrastructure, operations and reliability.

Seeking a Just System

Both ISO-NE and PJM have said that they would much prefer that all their generators provide every watt they have contracted to supply. But realistically that won’t happen, so the new arrangement, they hope, will enable timely, transparent and fair replacement power.

“There are no penalties in our design,” White said. “This is a true two-settlement obligation, just like any other commodity contract.

“We know that penalties are not insurable, so we were careful not to structure the market that way. This is covering a short position where every party knows the terms.

“The risk can be indexed to a transparent development outside the control of the insured, so there is no moral hazard. Insurers can model the system.”

Insurers are doing exactly that. Manfred Schneider, head of engineering in North America for Allianz, confirmed that fines or penalties would not be covered under standard business interruption (BI) coverage.

“We are working with our alternative risk transfer group looking for financial solutions to this non-typical exposure. We have to find the framework, the limits, the exposures. This is not just something you can lift out of the drawer.”

Schneider said that it could take another six to 12 months for Allianz and other carriers to work through the full underwriting, including assessing the needs, costs and potential size of the market.

A History of Coverage Ambivalence

One important concern for underwriters is that owners may choose not to buy policies after they invest time and effort into developing coverage for generators’ exposure under the new rules.

That would not be unprecedented.

One carrier recalled that BI coverage was not triggered when an ash cloud from a volcano in Iceland essentially locked down all transport in Europe for more than a week in 2010 because there was no physical damage.

Raw materials, inventory and parts could not be delivered, and many operations were halted. Insurers developed new policies, but owners deemed them too expensive and did not buy them.

“This is very new and we are being very careful.” — anonymous electricity industry source.

The same thing happened after Hurricane Ike swept over the Gulf Coast in 2008.

Cities were evacuated and refineries and chemical plants had to close for lack of workers. The storm did relatively little damage, but plants incurred the costs of shutdown, idleness and restart.

Again, at least one carrier developed “spin-down” insurance to cover such non-damage costs, but owners did not buy it.

“Swiss Re has seen a sharp increase from risk managers, CFOs and the heads of power trading inquiring about coverage options for generators participating in binding capacity performance markets,” said Brian Beebe, head of origination in North America for environmental and commodity markets with SwissRe Corporate Solutions.

“Since the magnitude of potential penalties for generator non-performance is extraordinary — millions of dollars an hour for a 500 Mw plant — the risk mitigation topic has been elevated within generation company senior management, including boards of directors.

“In response, generator risk managers and insurance brokers are seeking a variety of forward starting coverage options for key generation capacity.

“Clearly, the evolution of increased transparency and client knowledge of generator capacity prices is underway in deregulated markets. However, in traditional regulated utility markets, I do not see evidence that these areas are adopting any type of market-based mechanism to encourage generator availability.”

The high penalty charges have indeed caught the attention of corporate boards at generators, and they are pressing their risk managers for answers.

None that Risk & Insurance® contacted were willing to speak publicly, given that the situation is in flux and that they have to report first to their boards.

A significant concern among risk managers is not the availability of risk-transfer options, but the price, terms and conditions.

Several large generating companies serve both ISO-NE and PJM. Those contacted did not reply or declined to comment citing “competitive issues.”

One official observed, “This is very new and we are being very careful.”

It is expected that some of the larger corporations will retain the risk posed by the charges. That expectation in turn is making some risk managers anxious that lack of demand will limit participation by carriers and keep rates high.

Only time will tell how broad and deep this risk-transfer market becomes, and where capacity and rates settle. But one other concern raised about the new charge-and-payment scheme can be addressed. There has been a thought that small generators, especially those in renewable power, are essentially shut out, because they cannot commit to large delivery contracts.

That is not the case, said ISO-NE’s White.

“We know the status of every generator, updated every few seconds. If a wind generator cannot make a commitment to deliver, they don’t get the up-front payment, but they can be on standby.

“If the wind is blowing and they can supply during a delivery event, we will pay them the rate same as anyone else.”

The Doctor as Partner

Consulting clinical expertise can vastly improve disability and absence management outcomes.
By: | January 4, 2016 • 6 min read

Professionals helping employees return to work after being on disability or a leave of absence face many challenges. After all, there is a personal story behind each case and each case is unique.

In the end, the best outcome is an employee who returns to the job healthy and feeling well taken care of, while at the same time managing the associated claim costs.

Learn what most employers want from their group disability and life benefits program.

While many carriers and claims managers work toward these goals, in the end they often tend to focus on minimizing costs by aggressively managing claims to get the worker back on the job, or they “fast track” claims, approving everything and paying little attention to case management.

Aggressively managed claims can leave many employees and their doctors feeling defensive and ill-at-ease, creating an adversarial relationship that ultimately hinders return to work and results in higher direct and indirect employee benefit costs for the employer. Fast track or non-managed claims can lead to increased durations, costs and workforce productivity issues for employers.

Is it possible to provide a positive employee benefit experience while at the same time effectively managing disability and lowering an employer’s overall benefit costs?

A Unique Approach

Yes.

Liberty Mutual Insurance’s approach to managing disability and absence management focuses on building consensus among all stakeholders – the disabled employee, treating physician, employer and insurer. And a key component of this process is a large team of consulting physician specialists, leading practitioners from a variety of specialties, highly regarded experts affiliated with leading medical universities across the country.

“About 16 years ago, our national medical director, Dr. Ed Crouch, proposed that if we worked with a core group of external consulting medical specialists – rather than sending most claims for Independent Medical Evaluations – we could do a better job making disabled employees and their attending physicians comfortable, and therefore true partners in producing better disability management outcomes and employee benefit experiences,” said Tim Kastrinelis, senior vice president, Distribution Partnerships at Liberty Mutual Benefits.

“In this way, our consulting physician and the attending physician are able to work with the disability case manager, the employee and the employer to deliver a coordinated, collaborative approach that facilitates a productive lifestyle and return to work.”

The result of Dr. Crouch’s initiative has produced positive results for the clients of Liberty Mutual Insurance. This consensus building approach to managing disability with consulting physician expertise has helped achieve industry leading client retention results over the past decade. In fact, 96 percent of Liberty Mutual’s group disability and group life clients renew their programs.

A Collaborative Approach

In the case of complex disability medical health situations, Liberty Mutual’s disability case managers play a vital role in seeking additional expertise—an area where the industry’s standard has been to outsource the claimant for independent medical examinations.

However, Liberty Mutual empowers its disability case managers with the ultimate responsibility for the outcome of each claim. The claimant and the case manager stay together throughout the life of the claim. This relationship is the foundation for a collaborative approach that delivers a better employee benefit experience and enables the claimant to return to work sooner; which more effectively controls total disability claim and absence costs.

Sending a disabled employee with complex medical needs to an external specialist may sound like a cost-effective path, but it often comes at the cost of sacrificing the relationship and trust built between the employee and case manager. The disabled employee must explain their medical history to a new clinician, which he or she is often reluctant to do. The attending physician may be uncooperative as this move can appear to question his or her treatment plan for the employee.

As a result, the entire claims process takes on an adversarial atmosphere, building major roadblocks to the ultimate goal of helping the claimant return to a productive lifestyle.

Liberty Mutual takes a different approach. Nearly 100 physicians representing more than 30 medical specialties are available to consult with its medical and claims professionals, working side-by-side with case managers.

More than 95 percent of these consulting physicians are in active practice, and therefore up-to-date on the latest clinical best practices, treatment guidelines, therapies, medications, and programs. Most of these physicians are affiliated with leading medical universities across the country. “We recruit specialists from around the country, getting the best from such prestigious institutions as Harvard, Yale, and Duke,” said Kastrinelis.

These highly-credentialed physicians help case managers focus on providing the support needed for the disabled employee to successfully return to work as quickly as appropriate. Their collaborative work with the attending physicians provides the behind-the-scenes foundation that leads to a positive claimant experience, results in a better outcome for the claimant, and more effectively reduces total claim costs.

Coordinated Care Plan

When one of these consulting physicians reaches out to an attending physician, there’s an immediate degree of respect and high regard for his or her opinion. This helps pave the way to working together in the best interest of the employee, improving treatment plans and return to work results.

In this process, the claimant is not sent to yet another doctor; instead, the consulting specialist works with the attending physician to help fill in the gaps of knowledge or provide information that only a specialist would have. Although not an opportunity to direct care, these peer-to-peer discussions can help optimize care with the goal of helping the employee return to work.

The attending physician may have no knowledge of the challenges the employee faces in order to return to work. A return to work plan created in concert with the specialist, disability case manager, employer, and attending physician can set expectations and provide the framework for a proactive and effective return to a productive lifestyle.

“Our consulting physicians bring sophisticated medical expertise to the discussion, and help build consensus around a return-to-work plan, helping us more effectively impact a claim’s outcome and costs, and at the same time provide a better claimant experience,” said Kastrinelis.

“We can work more collaboratively with the attending physician, manage expectations, and shepherd the employee through the process much more effectively and in a much more high-touch, caring, and compassionate manner. Overall, we’re able to produce better outcomes as a result of this consensus building approach.”

Better Outcomes

“Our approach – including the use of consulting medical experts – helped us significantly reduce disability costs over two years for one large health service company,” notes Kastrinelis. “We cut average short-term disability claim durations by 4.2 days in that time, while increasing employee satisfaction with our unique disability management model and collaborative, partnership approach.

How did Liberty Mutual’s unique approach lower claim costs, reduce disability duration and improve the benefit experience for one customer?

“By getting all stakeholders on the same page and investing heavily in consulting physician specialists, we have been able to lower claim costs and shortened claim duration for our group disability policyholders,” said Kastrinelis.

“Plus, we, the employee, and the employer also get the bonus of creating a better employee benefit experience. This model has shaped our disability and absence management program to more aptly reflect our core mission of helping people live safer, more secure lives. In the end, it’s a win-win for all.”
