  • EACs make it possible for entities to make reliable claims about their energy usage. They play an important role in tracking and assigning ownership to renewable electricity generation and use. Since electricity is not tangible and tracing specific electrons through the grid is not possible, it is important to use EACs as an accounting instrument to certify the factual characteristics of how, where, and when a MWh of electricity was produced. Standards bodies like the Center for Resource Solutions define baseline criteria for renewable energy generation, which adds value to RECs that qualify for certification. Clear, credible REC and EAC specifications support a robust voluntary market. 
  • There are additional labels that can inform purchasers about the quality of the EACs, beyond what is legally required in verification compliance. An assortment of labels exist across global markets, which include third party audits, verified social impacts, and verifiable environmental protection criteria. 
  • Examples of third party standards that independently audit EACs are Green-e® and EKOenergy. These labels verify the chain of custody for EACs to ensure that only one customer claims credit for the renewable energy and environmental attributes created. Eco labels often record the type of power plant, the vintage, project site, technology used, and its unique operational focus. Green-e® is the most stringent and widely used voluntary REC certification program in the U.S. that sets buyer protection and environmental standards for REC products. EKOenergy is an internationally recognized, nonprofit eco label for renewable electricity, gas and heat. Consuming renewable power that meets national or international standards is imperative.
