EAC: Energy Attribute Certificates

If you hear about #EAC for the first time and google it, you'll be confused for a brief moment. The acronym is widely used by various groups for different concepts. I am talking about the EACs in the #sustainability context, as in #EnergyAttributeCertificates .

EAC is a generic term that represents similar content but is named differently across regions. Below are some of the names used around the world, and there are many more specific acronyms on national level.

So what is it about?

An EAC is a sort of contract that indicates the attributes of a unit of energy (typically 1 MWh of #electricity ). The certificate includes information on

              • the technology used to generate the energy (e.g. solar PV, wind turbine)

              • the underlying energy source, if any (e.g. gas, coal)

              • the start and end dates of production

              • the identity and location (e.g. a unique identifying number)

              • the capacity of the generating installation (in megawatts or gigawatts)

              • the year the generating installation was built

              • the date on which the generating installation became operational

              • if the installation received public support (e.g. feed-in-tariff, investment support)

Interesting part is that EACs, like many other assets, can be held, traded and retired (cancelled) in specific tracking systems.

Why would a company need an EAC?

Let's go back a bit.

Energy can be generated from

              • #nonrenewable, #highemission sources (e.g. #fossilfuel),

              • #renewable , #lowemission sources (e.g. #solar, #wind, #hydro, #geothermal) and

              • non-renewable, low emission sources (e.g. #nuclear). 

#Utility companies might collect and mix different types of energy and distribute it via regional grid to end users (organizations and households). Without documentation and #verification, it is impossible for the buyer (e.g. company) or the seller (e.g. #energysupplier) to quantify the #greenenergy portion within the total traded energy and claim a reduction in emissions.

EACs are tracked with EAC systems to quantify the #environmental benefits, associate the benefits with the correct parties and avoid #doublecounting the #emissionreduction.

What are the benefits of EACs?

EACs contribute to clean energy targets of the energy suppliers and the end users. On the largest scale, it benefits the Environment, and all the internal & external stakeholders of companies. More specifically, it helps with

Ø  validating energy suppliers’ claims about low emission energy generation

Ø  validating companies’ claims about renewable energy use and environmental responsibility

Ø  leaner greenhouse gas accounting and significant reduction in Scope 2 emissions

Ø  adhering to power source and emissions disclosure policies.

Ø  adhering to the standards of CDP, RE100, SBTi, etc.

Ø  affordable and easy reduction of emissions in counties where PPA or company-owned on-site generation is too costly or complicated

Ø  higher control over the cost and time spent to reach renewable energy targets

Ø  higher control on the choice of renewable energy source

Ø  ability to trade EACs like other assets 

Ø  substantiated support for the renewable energy initiatives of power generators. 

How does an EAC work?

The process for companies is straightforward. They buy an EAC, retire it and claim the benefits listed on the certificate.  

Issuers in Europe and around the world

The diagram above shows the EAC issuing bodies in Europe and the one below shows the issuers under the I-REC Standard. The 2020 publication “Understanding EAC Schemes and Roadmaps for Their Development” by the International Tracking Standard Foundation is available online and it provides more information on the topic.

How different is it from carbon credits?

An EAC that is held and used (retired / cancelled) by a company proves that the indicated amount of energy was generated from the renewable, low-emission sources. In other words, the company does not cause high emissions in the first place. EACs are issued and claimed in the same region as the company facility that consumes the energy.

A carbon credit represents the company’s financial support for the projects that capture, remove or avoid GHG emissions. This engagement focuses on compensating for the negative impact of the emissions that are already caused by the company. Carbon credit projects do not have to be located in the same region as the buying company.

Another way to look at the differences is provided by the US Environmental Protection Agency. As the scheme is called Renewable Energy Certificate (REC) in USA, we will share their nomenclature.

As they are different but complimentary tools, a company can use both EACs and carbon credits for the same reporting year. Firstly, EACs help reduce the indirect emissions, and carbon credits help offset the remaining emissions.
