The Australian Energy Regulator (AER) made its final revenue determination for the System Strength Project in New South Wales on September 23 and published it on September 30. The decision establishes which prudent and efficient project costs transmission operator Transgrid can recover. The revenue period runs from October 1, 2026 to September 30, 2031. The AER said it made the decision within the required 126-business-day period and that the infrastructure planner had notified it that financial close had been achieved before publication. The determination is not the same as construction or commissioning of the project; it governs the regulated revenue and cost-recovery mechanism.

Transgrid’s project involves deploying 10 synchronous condensers to maintain voltage and system stability on the New South Wales transmission network. The proposal submitted to the AER would put two units at each of five locations across the state, from Darlington Point in the south to Armidale in the north. The regulator says meeting system-strength standards is one of Transgrid’s responsibilities. The project followed a 2025 transmission-planning process that identified a potential future shortfall in system strength and a priority-infrastructure direction from the state government. The AER is not the body that chooses the project’s technology, scope or timing; it assesses the eligible costs in the revenue proposal against the applicable rules.

The AER classified its determination as a hybrid revenue decision. That approach reflects a project with both competitively procured, or contestable, elements and non-contestable components. The regulator says it may treat results of genuine competitive processes as prudent, efficient and reasonable in its assessment. Its role is to decide how much of the revenue sought by Transgrid can be recognized within the regulatory framework, rather than to select the investment’s scope or schedule. This distinction matters because the revenue decision should not be presented as a new project approval or announcement of a construction timetable.

The allowed amounts enter a recovery chain through the Scheme Financial Vehicle in New South Wales. Under the determination, that vehicle pays Transgrid; it then recovers the project costs and other NSW electricity-roadmap costs from distribution companies in the state. Distributors may pass those costs to customers through retail electricity bills. The AER said the amounts may be amended annually through approved adjustment mechanisms if specified circumstances arise. The determination therefore sets a five-year revenue framework but does not guarantee that annual recovery will be identical in every year. The AER’s summary page does not provide an overall project-cost figure, and this account does not invent one.

The regulator’s page describes synchronous condensers as equipment used to maintain voltage and system stability. Although the project is called a system-strength project, it is not described here as new electricity-generating capacity. The AER says transmission planning in 2025 identified a potential future shortfall; that does not mean a current outage or realized supply problem occurred. The September 23 revenue decision defines the regulated recovery path for the planned infrastructure costs. This report conveys the scope, parties, dates and equipment count stated by the regulator and does not add an unsupported commissioning date, total cost or definite effect on consumer bills.
