For earners

Your rooftop solar already displaces grid power. Now it can be measured.

CRIOS is for owners of rooftop and small commercial solar in Minas Gerais, Brazil. Once your plant is found and verified in Karbera, its metered generation can be issued as CRIOS-RE on testnet.

Find your plant in Karbera

Your installation needs to be discoverable in Karbera's measurement platform for distributed generation.

Prove ownership

Match your CNPJ or CPF against the plant registration. Until this is done, any figures shown are Tier 0 modeled estimates and are not retirable.

CRIOS-RE accrues from metered kWh

Once linked, Karbera-metered generation for each period × the official grid factor is issued as a testnet event.
