Asset Climate Resilience

Every solar plant, wind farm and substation was engineered against a design event (a wind gust, a temperature, a hail size) drawn from the climate record available when it was built. Climate change moves that record. At some point the design event stops being the once-in-fifty-years case and becomes ordinary. This service identifies when: the point of no return for each site in a portfolio.

The engine already exists and works. It fits a non-stationary extreme value distribution to the full record of annual maxima, with the distribution’s location shifting through time, producing a smooth return-level trajectory that is far more stable than re-fitting rolling windows. Comparing the future return level against the plant’s design value gives both the year of exceedance and the change in design load, which for wind scales with the square of velocity under the standard engineering codes.

The natural extension is to the hazard that actually destroys solar plants. Hail causes around three-quarters of utility-scale solar losses by value from a small minority of claims, and insurers are repricing accordingly. Adding hail exposure and heat derating alongside wind turns a single-hazard study into the portfolio climate risk assessment that lenders and insurers are now asking owners to produce.
