The Australian Government has launched two new Capacity Investment Scheme (CIS<\/strong>) tenders targeting the South-West Interconnected System (SWIS<\/strong>) in Western Australia, one of the country\u2019s largest isolated power networks. The move is part of a broader national strategy to accelerate the energy transition and secure grid stability as renewable energy replaces fossil fuels.<\/p>\n\n\n\n

The dual tender, announced on 29 August by Climate and Energy Minister Chris Bowen<\/a>, is expected to stimulate up to AU$4 billion (US$2.62 billion) in private investment and deliver enough clean energy to power more than 900,000 households<\/strong> annually. It will also introduce 2.4GWh of storage capacity\u2014sufficient to support evening peak loads for 550,000 homes<\/strong> over four hours.<\/p>\n\n\n\n

Single-Stage Tenders to Accelerate Delivery and Increase Grid Resilience<\/strong><\/h2>\n\n\n\n

According to the Department of Climate Change, Energy<\/a>, the Environment and Water, these will be the first CIS tenders to adopt a streamlined single-stage process<\/strong>, designed to condense the typical nine-month bidding cycle to roughly six months. This consolidation of technical and financial proposals aims to expedite the signing of Capacity Investment Scheme Agreements (CISAs)<\/strong> and accelerate the deployment of critical infrastructure.<\/p>\n\n\n\n

Both tenders are focused on delivering a combined 1.6GW <\/strong>of new renewable generation and 2.4GWh <\/strong>of dispatchable energy storage, which will directly feed into the Wholesale Electricity Market (<\/strong>WEM<\/strong><\/a>)<\/strong>. <\/p>\n\n\n\n

The WA tenders are part of a national CIS programme that targets the deployment of 40GW of renewable energy and dispatchable capacity by 2030. To date, six rounds of CIS have already locked in 12.3GW of generation<\/strong> and 6GW of storage<\/strong>, according to the government.<\/p>\n\n\n\n

Tender registration is open until 10 October 2025<\/strong>, with submissions closing on 7 November<\/strong>. Successful bidders for Tenders 5 and 6 will be announced in March 2026<\/strong>.<\/p>\n\n\n\n

Addressing Western Australia\u2019s Unique Energy System Challenges<\/strong><\/h2>\n\n\n\n

Western Australia\u2019s SWIS<\/strong> operates independently of the National Electricity Market (NEM), making it especially reliant on local generation and storage. The system has faced increasing challenges from the high penetration of rooftop solar<\/strong>, which has significantly lowered daytime demand and caused a growing dependence on dispatchable storage during peak hours.<\/p>\n\n\n\n

Tender 6 specifically aims to address these dynamics by procuring flexible, four-hour duration storage assets<\/strong> that can maintain grid balance when intermittent sources decline. The model follows the successful example of Tender 2<\/strong>, which earlier this year secured 2,595MWh<\/strong> of dispatchable capacity through four projects, including the Boddington Giga Battery<\/strong> and the Merredin Big Battery<\/strong>.<\/p>\n\n\n\n

According to Energy-Storage.news, interest from the private sector remains strong, with prior rounds oversubscribed and several projects already under development. The CIS initiative is regarded as a cornerstone of Australia\u2019s decarbonisation efforts, not only by unlocking investment but also by strengthening reliability across increasingly renewable-powered networks.<\/p>\n","protected":false},"excerpt":{"rendered":"
