data stream means a stream of metering data associated with a
connection point, as represented by a NMI. A NMI may have
multiple data streams (for example, from one or more meters, or
one or more channels or registers that comprise a single meter).
Each data stream is identified by a unique suffix associated with the
NMI to which it belongs.
financially responsible participant means a person who is
financially responsible for a connection point.
MDFF Specification means:
(a) the Metering Data File Format Specification published by
NTESMO in a communication guideline under clause S7A.1.3;
or

NTESMO – the Metering Data File Format Specification NEM
12 and NEM 13, published by AEMO, with an effective date of
1 May 2022 (version 2.5).
Metering Data File Format means metering data that is in a form
that complies with the MDFF Specification.
metering provision services means the provision, installation and
maintenance of metering installations.
prepayment device means a metering installation that requires a
prepayment for the supply of electricity prior to consumption.
scheduled meter reading means an actual meter reading
performed in accordance with the usual reading cycle for the meter.
special meter reading means an actual meter reading performed
outside of the usual reading cycle for the meter.
vending services means, for a metering installation at a
connection point that is a prepayment device, services that allow
the financially responsible participant to sell electricity that will flow
through the prepayment device in the future for consumption, and
to receive payment in advance for selling that electricity.
Note
The following are examples of vending services:
(a) services for prepayments made by credit card through a website or app, or
over the telephone;
(b) services for prepayments made in person by cash or credit card to purchase
a physical token or unique code that must be entered into a prepayment
