AER - Pricing methodology guidelines - System strength pricing - marked up - 25 August 2022

On 25 August 2022, we published the final amendments to our transmission pricing methodology guidelines to include how to price system strength services in the National Electricity Market (NEM). Based on a rule change by the Australian Energy Market Commission in October last year, we have modified the guidelines to specify:

• the permitted methodologies for determining the system strength unit price, and
• the principles for forecasting system strength revenues.

For previous amendments to our transmission pricing methodology guidelines, please see the Pricing methodology guidelines 2014 webpage.
