How do environmental factors affect a power supply?

Power supplies heat themselves up at different rates and intensities, and environmental influences will impact how quickly a power supply is exposed to high temperatures. Designers have to factor in the additional heat of nearby equipment, self-heating from high loads, and radiant heat such as solar energy on an enclosure.

Do power supplies need to be housed outside?

Power supplies need to be housed outdoors, where the extreme heat of the summer and the extreme cold of the winter will both be present. Power supplies heat themselves up at different rates and intensities, and environmental influences will impact how quickly a power supply is exposed to high temperatures.

Does weather affect power supply and production?

To summarise, past work on the influence of weather on power demand and production has either been limited by considering only part of the system over a long time period, or the system for a small sample of years. Furthermore, most studies have focussed on supply-side changes, neglecting the changing nature and shape of future demand.

What is a large power outage?

A large power outage is defined by the U.S. Department of Energy as: 50,000+ customers affected or an unplanned loss of 300 MW. Outages, particularly those related to weather, are almost always accompanied by intersecting and related phenomena that result in economic, social, and health damages (Figure 2).

What factors affect health outcomes during power outages?

We illustrate co-occurring factors such as displacement, extreme temperatures, and air pollution, as well as vulnerability factors that might increase the risk of adverse health outcomes during power outages, including baseline health status, socioeconomic status, and social support.

What factors should be considered when evaluating a power outage?

Studies should consider factors such as duration (e.g., longer outages are likely much worse for health) and location (e.g., outages in San Diego likely have fewer impacts than outages in Maine in the winter). The lack of resolved spatial and temporal exposure data has also limited research.
