What is the “Annual Fuel Mix Disclosure and CO2 Emissions Report”?

The Commission for Regulation of Utilities (CRU) published the most recent “Annual Fuel Mix Disclosure and CO2 Emissions Report” in December 2024. It shows:

  • Each supplier’s electricity source breakdown (coal, gas, oil, renewables, etc.)
  • The carbon intensity (gCO₂/kWh) of each supplier’s fuel mix
  • Where energy suppliers get their power from (Ireland or abroad)

This helps businesses choose suppliers that align with their sustainability goals. You can find the “Fuel Mix and CO2 Emissions Disclosure” on CRU’s website.

Can businesses get 100% renewable energy?

In simple terms, yes – your business can get 100% renewable energy even if your supplier’s overall fuel mix is not 100% renewable.

Most top-tier energy suppliers in Ireland offer fully renewable energy plans to businesses. In some cases, opting for a renewable business electricity plan will not cost you anything. Other suppliers may add a small premium to your contract for a certified renewable electricity. This premium may vary, but it’s usually around 0.2-0.3 cents/kWh.

Fully understanding how your energy is sourced is important to avoid greenwashing. You can have a look at our “How to Avoid Greenwashing?” article for more information

How Suppliers Certify Electricity as “100% Renewable”

When you see that your supplier is sourcing 100% renewable energy, this does not necessarily mean that your energy originates from renewable sources in Ireland. A supplier may offer “100% renewable electricity” through one or more of the following methods:

1. Power Purchase Agreements (PPAs)

Large businesses can buy electricity directly from a specific renewable generator (like a wind farm or solar farm). This provides traceable, Irish-generated renewable power.

2. Irish Guarantee of Origin Certificates (GOs)

Suppliers buy Irish GOs to verify that energy is generated from certified renewable sources in Ireland. Each GO = 1 MWh of renewable electricity.

3. Imported Renewable Certificates

Some suppliers offset carbon by purchasing GOs from outside Ireland, such as Norway or mainland Europe. These are still classified as renewable - but less impactful for Ireland’s own energy transition.

Ireland’s Green Energy Supply – What to Watch Out For

In 2023, while 61% of electricity supplied in Ireland was classified as renewable, only about 34% was generated within Ireland. This means many “green” plans rely on imported renewable certificates - which may not support local infrastructure or emissions reductions. Be aware of:

  • Greenwashing through imported certificates
  • Suppliers with a renewable product but a mixed fuel mix
  • Lack of transparency about sourcing
