Settlement and non-energy cost recovery (NECR) changes

Fundamental change - move from current category-based approach to a directional approach:

• “Generator” and “customer” energy will become “sent out” and “consumed” energy, regardless of the type of connection point
• Changes to the way NEM participants pay for “non-energy” services i.e. costs of ancillary services, interventions etc.
• Major AEMO database structure changes required to enable the new calculations, these changes will flow into the Data Model and affect participant reconciliation and reporting activities and also AEMO data provision.

Non-energy cost recovery will change to recovery from cost recovery market participants (CRMPs) based on their proportion of sent-out or consumed energy. CRMPs are: Market generators, Integrated Resource providers, Market customers.

New/updated National Meter Identifier (NMI) Classification Codes

Via the Retail Procedures, 3 new codes and amendments to 2 further codes will be implemented under IESS for:

• Identifying integrated resource systems (IRS) and removing the current use of two NMIs for grid-scale storage facilities
• Appropriate application of market fees and unaccounted-for-energy (UFE)
• Incorporating changes relating to the new Small Resource Aggregator category
• Enabling appropriate compliance monitoring to protect the integrity of market settlements.

Introduction of new, near universal participant type – Integrated Resource Provider (IRP)

New category will help simplify registration, particularly for battery participants who currently need to register as both a customer and a generator.

An Integrated Resource Provider will be able to classify a wide range of units.
Facilitated transition to Integrated Resource Provider (IRP) participant type for:

• Integrated Resource System Participants (BESS and pumped hydro) 
• Small Generator Aggregators
• Non-customer load participants

Optional transition for Semi-scheduled generator with non-scheduled battery

Facilitating bi-directional units (BDU)

A new unit type for plant (such as a battery) that can act as a generator and a consumer of electricity.
