All EU member states are required to establish and maintain a Renewable Energy Guarantees of Origin (REGO) scheme. The purpose of the scheme is to promote and increase the contribution of renewable energy sources to electricity production across the EU, providing a common platform to facilitate the trade of renewable electricity between member states.
In addition, the scheme sets out increased transparency to consumers, allowing them choice to purchase renewable or non-renewable electricity.
The scheme came into effect in October 2003 in Great Britain and November 2003 in Northern Ireland. The regulations governing the schemes were amended in 2010.
We administer the scheme for generation in Great Britain on behalf of the Department of Energy and Climate Change (DECC), and in Northern Ireland on behalf of the Northern Ireland Authority for Utility Regulation.
REGO is also the name of the certificate we issue to certify that the electricity was produced from eligible renewable energy sources. We issue REGOs to accredited generating stations located in Great Britain and Northern Ireland.
One REGO is issued for each megawatt hour (MWh) of eligible renewable output generated (with effect from 5 December 2010). Prior to 5 December 2010 one REGO was issued for each kilowatt hour (kWh) of eligible renewable output generated. The primary use of REGOs in Great Britain and Northern Ireland is for Fuel Mix Disclosure (FMD). FMD requires licensed electricity suppliers to disclose to their customers, and potential customers, the mix of fuels (coal, gas, nuclear, renewable and other) used to generate the electricity supplied annually.
The CCL and REGO team also regularly report to HMRC and DECC, as well as being responsible for the annual Fuel Mix Disclosure compliance deadline.
