Unlike the catalog of NERC Reliability Region that arises
out of its connection to transmission and reliability councils, and unlike
the catalog of state related utilities that arises out of regional
orientation, and unlike the catalog of Natural Gas, Pipeline and Petroleum
companies that arises out of a connection to fuel supply, this catalog of
Multi-Regional and Multi-National companies arises out of desire to buy,
sell or produce electricity or to buy, sell or build power plants for
wholesale electric markets unbounded by other relationships to the markets
and is, therefore, not easily classified by any other category.
Subsidiary companies are listed as subordinate to parent
companies. So if you are unfamiliar with the name of the parent
company on this page, perform a search/find on the name you are seeking.
