The Certificates of Origin Register (COR) is an integral element of the support system for RES energy manufacturers, and of the energy efficiency certificate system. Centralised registration ensures the reliability and transparency of the system. Certificates of origin are issued by the Energy Regulatory Office in electronic form, for a specific volume expressed in MWh (the exception is white certificates, for which the unit is the toe – ton of oil equivalent). All certificates issued by the ERO go to the Certificates of Origin Register maintained by TGE. Each certificate fed into the system results in property rights (PR), which are traded on the Property Rights Market (PRM).

PMOZE_A – so-called green certificates confirm the generation of electricity from RES – wind, hydro, geothermal, solar, biomass burning, co-firing.

PMOZE_BIO – so-called blue certificates issued for the generation of electricity from RES – biogas combustion.

PMEF – so-called white certificates, i.e., documents confirming final energy savings and are awarded for investments aimed at reducing end-user energy consumption.

A guarantee of origin of electric energy produced from renewable energy sources in renewable energy source installations, issued in electronic form, is the only document that certifies to the end user the environmental values resulting from greenhouse gas emissions avoided, and that the amount of electric energy injected into the distribution network or transmission network specified in this document was produced from renewable energy sources. Guarantees of origin are a trading instrument in all European Union Countries and other countries of Europe and the world.

They come in several varieties, including:

• AIB – guarantees of origin produced in one of the European countries affiliated with AIB (Association of Issuing Bodies)
• Non-AIB – guarantees of origin not affiliated with the AIB system (e.g., guarantees produced in Poland or Bulgaria).
• REGO – guarantees of origin from the United Kingdom.

We offer guarantees of origin at wholesale prices for energy generated from Polish renewable sources, which take into account place, time and technologies, such as: wind, solar, hydro, geothermal, biogas.

I-REC (International Renewable Energy Certificate) – a certificate used in countries with no organised system of guarantees of origin (e.g., Vietnam, Brazil, some African countries).

Offsets – certificates that document a reduction in carbon footprint. When the number of carbon credits earned equals the carbon footprint of a person or organisation, that person or organisation is carbon neutral.
