How does it work?

Renewable electricity certificates operate on a smart but simple premise: every MWh of electricity is given a certificate that attests to how and where it was produced. So if you use them, you can easily prove that your electricity comes from clean and sustainable sources.

There are various types of Renewable electricity certificates, but if you don’t know your GoOs from your I-RECs, don’t worry. We can set you up with the right solution for your needs. To set you on the right track, there’s a quick guide to certificate types just below.

What you need to know

There are many different Energy Attribute Certificate schemes around the world. At ACT, we have the expertise and global reach to let you access them all. Here is a brief overview of some of the certificates and their characteristics.

 

Certificate check

Guarantee of Origin

A Guarantee of Origin (GoO) is a European certificate that guarantees the origin of electricity. A GoO contains information about the production source of the electricity, including its location, commissioning date and the installed capacity of the power plant. One electronically issued GoO equals one megawatt hour (MWh) of power.

Certificate check

I-REC

I-REC is a globally recognized Energy Attribute Certificate scheme that builds on the best practices from the Guarantees of Origin (GoO) in Europe and the REC system in North America. By using I-RECs you can document and report renewable energy sources consumed outside of Europe and North America. One electronically issued I-REC equals one megawatt hour (MWh) of power.

Certificate check

TIGR

The Tradable Instrument for Global Renewables (TIGR) is a recognized Energy Attribute Certificate scheme that represents the renewable attributes of one MWh of renewable generation. The TIGR certificate helps corporates to purchase renewable energy in a transparent and standardized way. One electronically issued TIGR equals one megawatt hour (MWh) of power.

Certificate check

REC

A North American Renewable Energy Certificate (REC) is a market-based instrument that represents the property rights to the environmental, social and other non-power attributes of renewable electricity generation in the US and Canada. One electronically issued REC equals one megawatt hour (MWh) of power.

Certificate check

REGOs

A Renewable Energy Guarantees of Origen (REGO) is a certificate that guarantees the origin of Renewable Electricity produced in the United Kingdom. A REGO contains information about the production source of the electricity, including its location, commissioning date and the installed capacity of the power plant. One electronically issued REGO equals one megawatt hour (MWh) or renewable power.

Quality Labels for additionality

There are different additional quality labels for renewable electricity certificates.

The value of renewable energy certificates

The global power grid is constantly being fed by energy from both renewable and conventional sources. So how can we tell which energy is sustainable, and which comes from fossil fuels? The answer is simple: renewable electricity certificates. This official, globally recognized system allows producers, suppliers and even individual households to prove their use of clean energy.
