The non-renewable supply (not backed by REGOs) comprises the other sources mentioned in the table, and also accounts for:
- Transmission and distribution losses (a small reduction in the voltage transmitted across the network from power generators to those consuming power);
- The supply to customers with legacy contracts that didn’t specify renewable power;
- The supply to out of contract customers and those on a deemed rate. If you’re in either category, talk to us – we may be able to set up a new supply contract that saves you money and makes your organisation more sustainable.

Our fuel mix
As part of Drax, One of the UK’s largest suppliers of renewable energy to business, we back each megawatt hour (MWh) of the renewable source electricity we supply with a certificate from Ofgem. The energy regulator issues Renewable Energy Guarantee of Origin (REGO) certificates for generation taking place in the UK.
A proportion of the electricity we supply comes from Drax Power Station, near Selby in North Yorkshire. Predominantly, the plant uses sustainable biomass sourced from established, responsibly-managed working forests. We also have power purchase agreements with around 2,300 independent, UK-based generators.
For European sources, we get Guarantee of Origin (GOO) certificates.
When you’re on supply with Opus Energy, your contract is with either Opus Energy (Corporate) Limited – if you’re a corporate customer – or Opus Energy Limited if you’re a SME customer. Please refer to your bill to check which category you’re in, then see the relevant fuel mix disclosure (as above).
If you’re contracted to receive 100% renewable electricity via either our Opus Advance or Opus Advance Plus supply plan, please see this downloadable PDF.
