The Report Card for America's Infrastructure, prepared by the American Society of Civil Engineers, gives the US Electric Grid a rating of D. Its summary says the following:
The U.S. power transmission system is in urgent need of modernization. Growth in electricity demand and investment in new power plants has not been matched by investment in new transmission facilities. Maintenance expenditures have decreased 1% per year since 1992. Existing transmission facilities were not designed for the current level of demand, resulting in an increased number of "bottlenecks," which increase costs to consumers and elevate the risk of blackouts."
ERCOT in Texas is trying to put 3 billion into infrastructure upgrade.

In 2011 Texas a power exporter had blackouts due to just a couple plants going off line due to the weather and that’s nothing compared to what is being discussed here.
