Where GO prices are heading over the next 12 months
Price forecasts for Guarantees of Origin (GOs) are scarce. Most market participants rely on broker quotes, recent trades and their own judgement. In 2026, the 2025 vintage rose from EUR 0.20/MWh in January to EUR 1.67/MWh in May before falling back. For every 100 GWh, that move was worth about EUR 147,000, so the timing of a trade mattered as much as the decision to trade at all.
Veyt’s rolling 12-month GO price forecast is now available. It adds a forward-looking view to broker quotes and in-house judgement. The forecast covers the three vintages closest to delivery, where most volume trades and prices move most. It is updated every Friday so your view stays as current as the market.
How the GO forecast works
Ten machine-learning models draw on Veyt’s supply-demand balance forecast, power and carbon prices, recent trades and seasonal patterns such as disclosure-deadline buying. Each model’s weight depends on how accurate it has been recently, so the models that track the market best count the most.
The spread between the models shows where the outlook is firm and where it is uncertain. Alongside their own analysis, traders can use the forecast to decide when to buy and sell, portfolio managers when to swap vintages, and risk managers when and how much to hedge.

Three key questions in the GO market
The forecast gives a forward view on three questions GO market participants ask:
- Where are prices for the nearest vintages heading over the next 12 months, compared with where they trade today?
- How is the spread between vintages expected to change, and what does that mean for swaps and forward hedges?
- When in the year is the best time to buy or sell, for example ahead of the disclosure deadline?
