Core business infrastructure for environmental banking
With Grexel’s software solutions you track the ownership of environmental commodities, such as Guarantees of Origin, renewable energy certificates, emission allowances or other commodities with complex structure. The central registry system is the heart of any commodity market providing vital core banking services.
From the business logic perspective, a central registry facilitates key processes and transactions, such as:
- Registration of production devices or projects including their ownership and aggregations
- Registration of account holders, auditing bodies and other market actors
- Receiving and aggregating of meter readings from plants, project information, auto declarations and their approval procedures
- Issuing of certificates or other commodities according to defined rules
- Transferring, exporting, importing and expiration of certificates according to defined rules
- Cancellation and withdrawal of certificates
- Integration to the surrounding technical infrastructure and other similar registries and communication hubs
- Transaction log and audit trail
- Public reporting of transactions
From an end-user point of view, Grexel’s registry solution is similar to an online banking web service with accounts, transfers, and reports. The system utilises robust security infrastructure with strong authentication and fine grained authorization.
