But it was not just a power grid failure. It was a widespread infrastructure failure that ultimately caused the power grid to fail too. > The widespread winter storm produced low temperatures across the region. This is an unusual event, much worse than the worst case that was considered in recent prior planning. The result was loss of power plants, loss of natural gas supply, felled power transmission lines, damaged gas pipelines, damage to water systems, and so on, across the board. There was a loss of more than 50 percent of generation capacity at the same moment as electric power demand surged above the predicted peak forecast.
