The Clean Energy Solutions Center, in partnership with the National Renewable Energy Laboratory, hosted this webinar on U.S. experiences with renewable energy tracking and claims.
Because the flow of electrons cannot be traced from generator to consumer, some accounting mechanism is needed to ensure that renewable generation is being added to the grid. In the United States, the concept of renewable energy certificates (RECs) emerged as a way to demonstrate compliance with renewable portfolio standards (RPSs), which require utilities to supply a certain percentage of renewable electricity. One REC is equal to one megawatt-hour of renewable generation, and it can be sold separately from the underlying electricity.
More recently, RECs started to be used by voluntary purchasers – institutions looking to purchase renewable energy to match their electricity needs; for example, as part of a corporate sustainability initiative, or to make a marketing claim (e.g., “this product was made with 100% wind power”).
The presentation explored REC definitions, explained how RECs are tracked and traded electronically, and examined the tradeoffs to buying and selling RECs. The presentation concluded with a comparison of how renewable attributes are tracked in other countries. The presentation was followed by an interactive question and answer session with the audience.
