REGO (Renewable Electricity Guarantee of Origin)

Written and checked by the Energy Merchants desk · Reviewed 3 October 2026

REGO stands for Renewable Electricity Guarantee of Origin. It is the electricity certificate in the federal Guarantee of Origin (GO) scheme administered by the Clean Energy Regulator. Each REGO represents one megawatt-hour of renewable electricity generated by an eligible facility. For the wider scheme, see Guarantee of Origin.

A REGO carries information about its source, such as the generator, the fuel or technology and the time of generation. A buyer can cancel it to back a claim that their electricity use was matched by renewable supply.

REGO and LGC compared

At the time of writing, LGCs have been cheap and oversupplied, roughly $6 to $9 in September 2026. REGO pricing, scheme settings and any restriction on creating both from the same output should be confirmed with the CER. Treat details here as a guide and not a rule book.

In practice

A commercial solar customer might ask whether there is a certificate they can use to say their electricity is renewable. The answer depends on the system. Rooftop systems creating STCs have, by the act of claiming them, transferred the renewable attribute to the scheme, which affects what can later be claimed. This is a known sticking point, so check the scheme guidance. See STC definition.

For installers, the practical advice is to keep the customer’s expectations straight. They receive a discount at installation through STCs, and they should not assume they hold a separate renewable claim as well.

Common confusion

REGOs are not LGCs with a new name. LGCs exist to meet a legal obligation. REGOs support voluntary claims. Another trap is assuming any renewable electricity is automatically a REGO. A certificate has to be created and registered.
