Participant
A Participant provides the following services to an Energy User:
- Registers an Energy User in the NZECS Registry and administers an Energy User’s account
- Negotiates with Registrants to purchase NZ-ECs on behalf of an Energy User
- Receives NZ-ECs transferred from a Registrant on behalf of an Energy User
- Redeems NZ-ECs against an Energy User’s energy consumption
- Provides information to an Energy User on the redemption of NZ-ECs.
Registrant
A Registrant provides the following services on its own behalf:
- Registers one or more renewable Production Devices that it owns in the NZECS Registry
- Issues NZ-ECs in the NZECS Registry as it generates from the Production Devices it has registered
- Negotiates with Participants to sell NZ-ECs
- Transfers NZ-ECs it has sold to Participants.
Energy User
An Energy User is an energy consumer that:
- has been registered in the NZECS Registry by a Participant
- has either purchased NZ-ECs or is interested in buying NZ-ECs.
A party may choose to register in the NZECS Registry for more than one of these roles. For example:
- an Energy User may choose to register as a Participant and undertake its own NZECS administration and negotiate directly with Registrants to purchase NZ-ECs
- a Registrant may also act as Participant and thereby enable the sale of the NZ-ECs it issues directly to an Energy User.
