NSW's ASL consults on 1.5 GW firming tender

ASL is consulting (13 October–4 November) on a 1,500 MW firming tender for the Sydney–Newcastle–Wollongong sub-region, requiring at least 8 hours of sustained output under LTESA contracts. View: the 8-hour threshold disadvantages 2–4-hour batteries and favours gas and long-duration storage.

Project

AEMO's 2025 Energy Security Target Monitor (central scenario): about 1,500 MW gap in 2033-34.

Financing

LTESAs are revenue-support contracts; terms are being designed in this consultation.

Policy

Tender expected to open in early 2027, targeting completion by end-May 2033; a contingent round around 2030 is possible.
