Just dig into power transformers.. If more than a few of these go down, some areas could be without power for a long time.

 

>Physical Characteristics of Large Power Transformers.

An LPT is a large, custom-built piece of equipment that is a critical component of the bulk transmission grid. Because LPTs are very expensive and tailored to customers’ specifications, they are usually neither interchangeable with each other nor produced for extensive spare inventories. According to an industry source, approximately 1.3 transformers are produced for each transformer design.

 

In 2010, the average lead time between a customer’s LPT order and the date of delivery ranged from five to 12 months for domestic producers and six to 16 months for producers outside the United States. The LPT market is characterized as a cyclical market with a correlation between volume, lead time, and price. In other words, the average lead time can increase when the demand is high, up to 18 to 24 months. This lead time could extend beyond 20 months and up to five years in extreme cases if the manufacturer has difficulty obtaining any key inputs, such as bushings and other key raw materials, or if considerable new engineering is needed.

 

The United States has limited production capability to manufacture LPTs. In 2010, only 15% of the Nation’s demand for power transformers (with a capacity rating of 60 MVA and above) was met through domestic production.
