Where your certificates trade.
European Guarantee of Origin markets — how they work, what moves prices, and why timing your sales with AI captures premiums that manual sales consistently miss.
Guarantees of Origin — the basics
A Guarantee of Origin (GO) is a 1 MWh certificate issued by a national energy regulator each time a renewable energy plant generates one megawatt-hour of electricity. The certificate certifies the source, technology and country of that generation.
Corporates buy GOs to substantiate Scope 2 electricity claims under ESG frameworks: RE100 commitments, GHG Protocol market-based accounting, and CSRD reporting obligations. As these frameworks expand, corporate demand for GOs grows.
GOs are traded on European markets. Prices vary — sometimes significantly — based on technology, country of origin, vintage and timing of demand. That variation is the opportunity.

What moves GO prices
GO prices are not flat. They respond to a set of structural and seasonal drivers that AI can track and anticipate far better than manual monitoring.
Corporate Compliance Deadlines
Most EU countries have a 31 March annual deadline for GO cancellation against Scope 2 claims. This creates a predictable demand surge in Q1 each year — prices typically rise 20–40% in January–March and drop sharply in April.
Technology Premium
Solar PV, wind, hydro and biomass GOs command different prices. Demand for specific technologies is driven by corporate sustainability commitments — some RE100 members specify technology type.
Country of Origin Premium
GOs from certain countries trade at a premium due to perceived additionality or local procurement requirements. Nordic hydro and Italian solar have historically commanded premiums over other origins.
Certificate Vintage
Current-year GOs trade at a premium to older vintages. Buyers prefer certificates matching their reporting year. Older vintages discount progressively as they approach the 12-month expiry limit.
Renewable Energy Mix
Countries with high renewable penetration generate more GOs, which can suppress prices. Countries with tighter supply relative to domestic corporate demand see higher prices.
RE100 and SBTi Growth
The growth of RE100 corporate signatories and SBTi commitments structurally increases GO demand year on year. As more corporates commit to 100% renewable electricity, the demand base for GOs expands.
Why timing matters more than you think
GO prices follow a recognisable seasonal pattern driven by the annual compliance calendar. Prices typically rise through Q1 as the March 31 cancellation deadline approaches, then drop sharply in April as compliance demand evaporates.
A second, smaller demand period often emerges in Q3 as corporates plan ahead for year-end reporting. Manual sellers who pick an arbitrary moment typically sell into a price trough. AI that tracks this seasonality sells into price peaks.
On top of seasonality, intraday and intraweek price movements create shorter windows. A corporate buyer with an urgent compliance gap can briefly move prices above the seasonal average. These windows last hours — not days.
