Lightning parametric insurance

Lightning parametric insurance pays when lightning strike activity of an agreed intensity is detected at or near your location, protecting the infrastructure that lightning damages or disrupts.

A strike can cause an outage far more costly than the physical damage, and proving cause under conventional cover is slow. Parametric settles the question with independent strike data.

This page explains what lightning costs a business, why traditional cover falls short, how Trigger structures lightning parametric cover, the trigger and data behind it, how basis risk is managed, an example structure, the businesses it suits, and how fast it pays.

What lightning costs a business

A lightning strike can knock out power, damage electronics and control systems, ignite fires and interrupt operations at critical sites such as energy assets, telecoms towers and data infrastructure. The immediate physical damage is often small compared with the downstream cost of the outage, the lost service and the emergency response. For operators whose value lies in continuous uptime, even a short lightning induced interruption can be expensive and hard to recover under a standard policy.

Where traditional cover falls short

Proving that a specific strike caused a particular outage is difficult and slow under conventional cover, and the consequential losses from downtime are often excluded or tightly limited. The result is that the real cost of lightning, the disruption rather than the damage, frequently goes uncovered. A strike detection trigger settles the question with data, paying on the confirmed strike activity rather than on a contested investigation of cause.

How Trigger structures lightning cover

Cover is built on a lightning trigger derived from strike detection networks, such as strike density above a level, or a confirmed strike within a defined radius of your site during the policy period. Payouts can be structured to fund rapid inspection, repair and lost operating time, and can scale with the intensity of the activity. The trigger and payout are fixed in advance, and settlement follows the confirmed detection data.

The trigger and the data behind it

The trigger uses independent data from lightning detection networks, which record strike location, time and intensity across wide areas in near real time. A trigger might be defined as a confirmed strike within a set radius of a critical asset, or strike density above a threshold. Because the detection networks are neutral and their data published, the outcome is objective and quickly available. Read more on the data used in parametric insurance.

Reducing basis risk on lightning cover

Basis risk on lightning cover comes from the relationship between detected strikes near a site and the actual impact on your equipment, which depends on protection and exposure. It is reduced by setting the radius and intensity thresholds to match the point at which strikes affect your operations, and by calibrating against your own outage history where available. Every trigger is tested against the detection record before cover is bought. Read more on how basis risk is managed.

Why lightning cover matters for critical infrastructure

Lightning is a small event with an outsized impact on infrastructure whose value lies in continuous operation. A single strike can take a telecoms tower, a substation or a data facility offline, and the cost of that outage, in lost service, emergency response and reputational damage, dwarfs the physical repair. As economies grow more dependent on always on infrastructure, the financial exposure to lightning is rising, particularly in regions with high strike activity. Conventional cover handles the physical damage poorly and the consequential outage even worse, because proving cause is slow and contentious. A strike detection trigger removes that problem entirely, paying on the recorded strike activity near a critical asset. For operators of infrastructure where downtime is the real cost, lightning cover offers a fast, objective way to protect uptime and fund rapid restoration, without a dispute over what caused the outage.

Example structure

A telecoms operator takes cover that pays when a strike is confirmed within a defined radius of a critical site, funding inspection, repair and the cost of downtime. When the detection network confirms a qualifying strike, the payout is settled within days, without a dispute over whether lightning caused the outage.

Which businesses and sectors it suits

Lightning parametric cover suits energy and utilities, telecoms and data infrastructure, construction, and public sector operators of critical infrastructure. It is valuable to any business whose uptime and equipment are exposed to strikes, particularly in regions with high lightning activity.

How fast the cover pays

Because there is no loss to assess, a lightning parametric policy pays within days of the detection data confirming the trigger. Strike data is available in near real time, so timing depends on confirming the reading rather than investigating cause, and funds arrive quickly to restore service. Lightning sits within our weather parametric insurance line, alongside the other perils measured by an independent index.
