All Energia household electricity plans are guaranteed 100% green. We match the electricity used by our household customers over the course of the year with an equivalent amount of electricity generated from renewable sources.
This is achieved through renewable generation and Guarantees of Origin certificates relating to renewable electricity generated in Ireland and Europe.
*Subject to verification through the CRU’s Green Source Product Verification process.
What this means for our customers
Every year, we work out our household customers’ electricity demand from the national grid. We then match this with an equivalent amount of renewable electricity through our wind farms, solar farms, other renewable generators and Guarantees of Origin certificates.
Electricity from renewable and non-renewable sources is combined on the national grid, so it is not possible to determine the exact source of the electricity used in an individual home at a particular time.
Each Guarantee of Origin is an electronic document providing proof that a quantity of energy was produced from renewable sources. The renewable generation and Guarantees of Origin supporting Energia’s green electricity products are reflected in its annual Fuel Mix Disclosure and assessed through the CRU’s Green Source Product Verification process.

Where does Energia’s renewable electricity come from?
Energia supplies renewable electricity through a combination of renewable generation in Ireland and Guarantees of Origin certificates relating to renewable generation in Ireland and Europe.
How does Energia invest in renewable energy?

Energia’s fuel mix disclosure
Our annual Fuel Mix Disclosure shows the sources used to match the electricity supplied to Energia customers, together with the associated carbon dioxide emissions. It allows customers to access information about their electricity sources and make informed choices about their supplier.
