Built to last: why insurers are helping design resilience into renewable energy and storage facilities

As renewable energy and storage industries grow, and enter more hostile geographies, asset resilience is becoming an increasingly pressing concern. Developers, owners and lenders want to know how solar, storage and other facilities can increase their resilience to the growing risks of physical threats such as hailstorms and wildfires. The rush to add capacity to meet surging demand from new data centres is adding to the pressure, making calculations about the value of asset reliability increasingly complex.

In this special episode, host Ed Crooks speaks with Mike Perron, Renewable Energy Market Lead at FM and Cassian Walker, Operations Vice President and Renewables Engineering Manager at FM, one of the world’s largest commercial property insurers. They explain how insurers are starting to build resilience into renewable project design far earlier in the development process, and why that has become a financing issue as much as a technical one.

For solar power, that means understanding the inherent physical risks such as hail, then deciding what combination of tracker systems, stowing technology and panels is right for the location. The same equipment that performs adequately in California or New Jersey can become a major liability in Texas or Arizona.

Cassian explains how modern trackers can tilt panels away from an incoming storm to turn a direct hit into a glancing blow. Mike contrasts a devastating nine-figure loss at one Texas site with a far smaller loss at another facility that successfully stowed. Those resilience strategies can work only if the system is designed for the local wind and hail conditions, and the performance of the equipment has been tested and verified.

From there, the conversation broadens to the economics. Insurance can account for a large share of a project’s operating costs, and lenders are asking harder questions about resilience before they finance new builds. FM’s case is that better engineering, better hazard modelling and earlier involvement from insurers and independent engineers can lower lifetime risk and improve financial performance, even if they raise up-front costs.

Today, renewable developers still often treat insurance as a late-stage procurement exercise, after key technology decisions have already been locked in. Mike and Cassian argue that that is changing, but the industry is still early in that learning curve. As renewables become more important to the power system, those questions will only get harder to avoid.
