An Energy Attribute Certificate (EAC) is a unique electronic certificate, which acts as proof that renewable electricity has been produced. EAC markets were created because electricity cannot be tracked between producer and consumer as other products can. When you buy power, you’re not buying physical electricity but rather the right to remove a given amount from the grid. The only way to track it is through a book & claim accounting system. That is why EAC’s are used to certify that the bearer owns one MWh of electricity generated from a renewable energy resource. These renewable energy certificates are issued by governmental organisations to track, prove and disclose the production and use of renewable electricity and can be sold or used as a credit against power usage.
Local Compliance Certificates
Many local governments use local compliance renewable energy certificates to demonstrate regulatory compliance and to meet local renewable energy goals. These certificates are market-based instruments that represent the property rights to the environmental, social, and other non-power attributes of renewable electricity generation.
Guarantees of Origin
A Guarantee of Origin (GoO) is a digital certificate and the only proof that energy has been generated in a renewable way. With a GoO, the supplier can demonstrate to the customer that the energy supplied comes from renewable sources, such as wind, water, sun, biomass, solar thermal and geothermal.
The I-REC(E) Code
An I‑REC for electricity is referred to as I-REC(E) and is an exchangeable Energy Attribute Certificate (EAC) that conveys information about the production of a unit of electricity, such as where the electricity was produced, the capacity of the Production Facility, and the energy source. I‑REC(E)s can be used for a variety of (voluntary) requirements including Scope 2 reporting, national energy reporting, and general End-user claims, and allows all electricity users to make a conscious and evidence-based choice for electricity, in any country where service providers have been Accredited by the I-REC Standard Foundation.
