People Mostly ask


What is an Energy Attribute Certificate (EAC)?

An Energy Attribute Certificate (EAC) is a contractual certificate that proves the type of energy sold by a supplier and used by a consumer. In this way, EACs are used to prove the origination of a given energy unit, whether it be from gas, thermal, nuclear or other renewable sources of energy. An EAC is typically issued for every one megawatt hour (MWh) of electricity generated.

EACs are especially relevant for organizations that are shifting more energy consumption away from fossil fuels and towards renewable energy sources. Whether for mandatory compliance or voluntary reasons (such as 24/7 hourly matching), EACs are the provable documentation that help organizations substantiate their clean energy consumption and carbon footprint reduction claims.

What are different Types of Energy Attribute Certificates?

The term EAC itself is a categorical term that encompasses any kind of tracking system for proving the origination of a given energy unit. While virtually every country in the world has some form of an EAC equivalent, not every country uses the same terminology. 

There are multiple variations of EACs based on geographical location. Some of these are international standards used by multiple countries, while others are national standards used by a single country.

International Standards

Renewable Energy Credits (RECs) – Standard used in North America

Guarantees of Origin (GOs) – Standard used by the majority of EU countries

International Renewable Energy Credits (I-RECs) – Standard used by most of Latin America, Africa, and Asia

National Standards

Renewable Energy Guarantee of Origin (REGOs) – Standard used by the UK

LGCs - Standard used by Australia

N-ZECs - Standard used by New Zealand

J Credits - Standard used in Japan

How do EACs Work?

For every MWh of electricity generated from a clean energy source, a single EAC (REC, GO, REGO etc.) is issued.

As such, there are two outputs generated: the actual renewable electricity generated (per MWh), and the EAC documentation that represents the existence of that MWh. It’s important to highlight here that these two entities are not mutually exclusive. That is, an organization can own an EAC but not have consumed the renewable electricity it represents.

This is because EACs are ultimately a tradeable, market based mechanism for ‘owning’ the legal claims to the origination of the renewable energy. 

While some organizations may want to sell their EACs as a way of driving additional revenue, other organizations may want to buy EACs in order to offset their carbon footprint. Ultimately, it is the owner of the EAC who has exclusive rights to any claims about consumption of the electricity associated with an EAC.

How do EACs contribute to renewable energy goals?

EACs are contractual certificates that organizations use to  verify that a unit of renewable energy has been generated to account for a unit of energy they have consumed. As such, without EACs, organizations have no verifiable documentation to substantiate their claims. 

Each EAC signifies one MWh of renewable energy, but there are other considerations to also consider when meeting renewable energy goals. For example, if the commissioning date of the renewable energy asset where an EAC was produced was 15 years ago or more, common sustainability standards like RE100 will stop accepting this as sufficient enough to prove zero energy related emissions from next year. This is because the aim of the RE100 scheme is to accelerate the transition towards carbon-free grids by 2040. This cannot be met without corporate buyers themselves contributing to renewable electricity capacity additions
