The Core Coalition was founded in 2020 as an alliance of companies active in the transformer industry and those industries that use transformer components in manufacturing, as well as users of transformers. The Coalition was formed to provide information in support of its position that the circumstances and quantity of imports of transformers, cores, laminations, and other transformer inputs do not threaten the national security of the United States (US).

TCC’s focus has shifted to highlighting the inadequate preparation for the future of the US electrical grid further exacerbated by the current global shortage of transformer steel production.
