1. (1) “Electricity from specified sources” or “purchases from specified sources” means electricity transactions that are traceable to a specific generation source by any auditable contract trail or equivalent, such as a tradable commodity system, that provides commercial verification that the electricity source claimed has been sold once, and only once, to an end user.
