Understanding REGOs: How Renewable Energy Guarantees of Origin Matter to Investors

REGOs are electronic certificates issued to generators for each megawatt-hour of electricity they produce from eligible renewable technologies. They separate the “green” attribute of power from the physical electrons traded in wholesale markets, allowing suppliers, corporate offtakers and consumers to claim the renewable provenance of the energy they purchase. Ofgem administers the REGO scheme in Great Britain and publishes guidance on registration and transfers.

It is important to understand that REGOs represent a trackable environmental attribute rather than a direct subsidy or guaranteed revenue stream. Some projects sell their power under a PPA and separately sell REGOs to customers seeking verified green credentials. The market value of REGOs can vary according to corporate demand for disclosed renewable provenance, voluntary market trends and the availability of other certification systems.

For project economics and investor returns, REGOs are relevant to non‑energy revenue lines: a stable route to monetise environmental attributes can improve predictability for small generators. However, REGOs alone rarely replace core power revenues and are typically one component alongside merchant sales, PPAs and any support mechanisms.

For retail savers buying fractional digital shares in renewable projects, recognising how REGOs are issued, traded and priced helps assess the sources of a project's revenue and the commercial model behind its environmental claims — a useful input when comparing opportunities and understanding where non‑energy income fits into overall returns.
