Compare 100% Renewable Business Electricity Suppliers

30-Second Overview

Businesses can secure 100% renewable electricity contracts from all major suppliers, regardless of each supplier's published fuel mix. The key differences are price, renewable certification and how the electricity is sourced.

For SMEs, renewable electricity provides an opportunity to demonstrate environmental commitments to customers, often at little or no additional cost. For Large Energy Users, renewable electricity procurement is increasingly driven by ESG reporting and corporate sustainability policies.

Renewable electricity contracts can be backed by international Guarantees of Origin (GOs), Irish GOs or Corporate Power Purchase Agreements (CPPAs). Understanding these differences is important when comparing suppliers, particularly where specific sustainability reporting requirements apply.

Which Business Electricity Suppliers Offer 100% Renewable Electricity?

All major business electricity suppliers can offer contracts backed by 100% renewable electricity, even where their published fuel mix includes electricity generated from fossil fuels.

Suppliers including Electric Ireland, Energia, Bord Gáis Energy, SSE Airtricity, Flogas, Yuno and Pinergy offer renewable electricity options for businesses. However, pricing, certification and sourcing arrangements differ between suppliers and contract types.

For SMEs, suppliers provide confirmation that their electricity contract is backed by 100% renewable energy through Guarantees of Origin (GOs). Businesses receive confirmation of their renewable electricity supply without needing to manage the underlying certification process.

For Large Energy Users, suppliers can provide formal GO cancellation certificates issued by SEMO, identifying the customer, the volume of electricity covered and the renewable generation asset. This provides the detailed traceability required for ESG reporting and corporate sustainability policies.

💡 Importantly, a supplier's published renewable fuel-mix percentage does not determine whether it can provide your business with a 100% renewable electricity contract.

What Is the CRU Annual Fuel Mix Disclosure Report?

The Commission for Regulation of Utilities (CRU) publishes an annual Fuel Mix Disclosure Report showing the proportion of electricity supplied by each supplier from renewable energy, natural gas, coal, oil and other sources. It also reports the associated carbon emissions in grams of CO₂ per kilowatt-hour (gCO₂/kWh).

The report provides a useful comparison of suppliers' overall electricity fuel mixes and associated carbon emissions. However, businesses should also assess the renewable certification, electricity sourcing and pricing of their specific contract when selecting a 100% renewable electricity product.

The table below shows the renewable electricity percentage and fuel mix reported for each supplier.

How Suppliers Certify Electricity as 100% Renewable

Electricity suppliers use Guarantees of Origin (GOs) to certify that electricity has been generated from renewable sources. Each GO represents 1 MWh (1,000 kWh) of renewable electricity generation and can only be used once. Businesses can choose between three main renewable electricity procurement options:

Does 100% Renewable Electricity Mean It Comes from Ireland?

A 100% renewable electricity contract does not necessarily mean the electricity was generated in Ireland. Electricity suppliers can use Guarantees of Origin (GOs) from renewable generators elsewhere in Europe to certify their electricity supply.

According to the 2024 All-Island Fuel Mix Disclosure Report, renewable electricity accounted for 62.35% of the disclosed fuel mix. However, this figure includes imported renewable certificates and does not represent the percentage of electricity physically generated from renewable sources in Ireland.

For businesses with specific ESG reporting requirements, the distinction matters. A contract backed by international GOs may satisfy one company's sustainability policy, while another may require Irish GOs or electricity linked to an identifiable Irish wind farm.
