(EAC).
In the context of clean energy, an energy attribute certificate is a contractual instrument providing information about the resources used to create a unit of energy, and the associated emissions.
- Examples and uses of energy attribute certificates
- "A common type of EAC in North America is the renewable energy certificate (REC), used for electricity suppliers and consumers. One REC conveys one megawatt-hour of electricity generated from renewable sources.
- Zero-emissions credits (ZECs), also called emission-free energy certificates, are another example. This type of EAC is often associated with nuclear generation with zero emissions.
- EACs are essential to substantiate claims about electricity sold by suppliers or used by consumers.
- EACs are held, traded, and retired within tracking systems to ensure each account holder has a unique claim to the specific energy attributes, whether that is used for compliance with a policy mandate or to substantiate voluntary green power use.
- Without EACs, two parties might claim the attributes of the same unit of electricity, leading to “double counting” which could skew the renewable energy marketplace.
- EACs are commonly used to validate claims about compliance with renewable energy standards, voluntary renewable energy purchases, greenhouse gas accounting, and power source and emissions disclosure policies."
