Description
Guarantees of origin (hereinafter referred to as GOs) are tradeable, electronic certificates, which prove that a certain share of the energy consumed was produced from specified, typically renewable, energy sources. Guarantees of origin can be registered after production, thus GO trading is disconnected from the physical electricity products; it is performed retrospectively. Buyers of certificates support the renewable energy producer, thus becomeing entitled to communicate that the volume of energy consumed and backed by GO certificates has been produced from the specified renewable energy sources. Sellers in the market are typically renewable power plants, who besides selling energy production can apply to issue their guarantees of origin. The EU proclaimed ambitious targets in terms of both demand and supply; therefore, increasing renewable capacities lead to the enlargement of GO supply.
Buyers of guarantees of origin are primarily companies that are committed to making their energy consumption greener and more sustainable, contributing to their marketing and PR values and to the positive recognition of their products and services. Such companies have three options to certify green consumption:
1) Building their own generation capacity, which has significant technical limitations;
2) Procuring electricity via PPA (Power Purchase Agreement) from a renewable power plant, which is risky in terms of prices and volume variability;
3) Purchasing guarantees of origin, retrospectively, independently from the electricity, thus minimizing the above-mentioned risks.
Within the third option detailed above, GOs may be traded either Over the Counter (OTC) or via an exchange, such as HUPX. While trading GOs via OTC allows for more price certainty and product flexibility, there are several advantages to trading via an exchange, listed below:
- Price transparency
- Higher Liquidity and Accessibility
- Credit Risk Mitigation
- Transactional Efficiency
