Default Electric grid large power transformers take up to 2 years to build

In an EMP event, we may not be able to get back up in a quick manner:

[Large power transformers are essential critical infrastructure to the electric grid, and are huge, weighing up to 820,000 pounds. If large power transformers are destroyed by a geomagnetic disturbance (GMD) electromagnetic pulse (EMP), cyber-attack, sabotage, severe weather, floods, or simply old age, the electric grid could be down in a region for 6 months to 2 years. This is because the USA imports 85% of them, there is competition with other nations for limited production and raw materials such as special grade electrical steel, a high cost ranging from $2.5 to $10 million dollars (including transport/installation), require close supervision, and are custom built, with long lead times to design, bid, manufacture, and deliver. The United States large power transformers are aging faster than they’re being replaced, and even more are needed for new intermittent renewable generation, which has the potential to damage them if not integrated carefully into the existing electric grid. There are possibly tens of thousands of LPT’s in America, mostly built between 1954 and 1978, so an increasing percentage of these aging LPT’s will need to be replaced within the next few decades.
