Peak heat brings power cuts and long backup usage, pushing machines, infrastructure, and daily systems closer to their limits.
Peak heat exposes the limits of infrastructure very quickly. Power cuts become more common, backups start carrying longer loads, and suddenly you are reminded that every system has a threshold.
This is true at the household level and at the city level. Inverters, batteries, air conditioners, transformers, and human patience all start operating under extended stress when the weather refuses to ease up.
There is something revealing about these periods. Extreme conditions show which systems were built with real capacity and which ones were only designed for average conditions. Heat does not just make life uncomfortable. It audits resilience.
