Western Australia’s clean energy transition continues to accelerate, with major new renewable projects, grid investment announcements, and updated technical standards reshaping the state’s electricity system. Here are the most important developments from the past 48 hours across renewables, batteries, transmission, and grid reliability.
Major Renewable and Battery Boost for WA’s Wholesale Electricity Market
The Australian Government has announced the successful projects from Capacity Investment Scheme Tenders 5 and 6, awarding contracts to ten new renewable energy and battery initiatives across Western Australia. These projects will deliver substantial new generation and storage capacity into the Wholesale Electricity Market (WEM), helping maintain reliability as ageing thermal generators retire and electricity demand grows.
- Approximately 1.886 GW of new renewable electricity generation capacity has been approved across the selected projects.
- The projects include 3.683 GWh of standalone battery energy storage designed to support reliability and peak demand management.
- Successful developments include multiple wind farms, a large solar-battery hybrid facility, and standalone battery systems to strengthen electricity supply.
WA Government Announces $1.4 Billion Clean Energy Fund for Grid Expansion
The Western Australian government is preparing a major funding package to accelerate transmission infrastructure and network upgrades as the state transitions away from coal-fired generation. The new Powering WA Clean Energy Fund will support critical projects needed to integrate higher levels of renewable energy across the South West Interconnected System.
- An AUD 1.4 billion fund will support major transmission developments including the Clean Energy Link (CEL) – East and CEL – North projects.
- An additional AUD 7 million has been allocated to Horizon Power for renewable energy transitions in regional areas including the Pilbara, West Kimberley, and Coral Bay.
- The investment is intended to maintain long-term grid reliability ahead of scheduled coal power station retirements.
New Solar and Battery Connection Rules Now Active in WA
Updated technical standards for small-scale rooftop solar and battery systems connected to Western Power’s network officially took effect on 1 May 2026. The new rules are designed to improve grid stability, enhance export management, and support broader participation in virtual power plant programs.
- New combined inverter capacity limits have been introduced for residential and small commercial installations.
- Network operators can now dynamically manage solar exports during periods of grid stress and oversupply.
- The changes aim to balance strong household renewable uptake with engineering reliability and long-term network stability.
Federal Scheme Delivers Strong Pipeline of WA Wind and Solar Projects
Further details from the Capacity Investment Scheme tender results highlight strong momentum in wind energy development, with six major wind farms accounting for the majority of the newly approved renewable generation capacity. The successful projects represent billions of dollars in infrastructure investment across regional Western Australia.
- Six wind projects totaling approximately 1.536 GW were approved alongside a 350 MW solar-plus-battery hybrid project.
- The developments are expected to generate enough electricity to supply more than one million homes while supporting overall grid stability.
- Standalone batteries associated with the projects will provide up to four hours of energy support during high-demand periods.
Western Australia’s energy sector continues to move rapidly toward a cleaner and more resilient future. With substantial investment flowing into renewables, battery storage, transmission infrastructure, and smart grid technologies, the state is positioning itself as a national leader in reliable low-emissions energy systems and modern electricity engineering.
