Bundled procurement means delivering electricity and EACs through unified transactions, as opposed to separate or independent transfers of unbundled EACs. The mechanism often describes a scenario whereby a producer sells power and certificates simultaneously to the same buyer through unified commercial mechanisms, such as PPAs. However, "bundled" does not strictly require that EACs originate from the exact same generator as sold energy, nor that they must correlate with the generation period of the electricity delivered. Rather, it only matters that energy and EACs are part of the same contract.
