Renewable energy and solar integration
Alinta Energy
Although Alinta ranks moderately in renewable ratings per Greenpeace’s 2020 Green Electricity Guide, it has stepped up investments in renewable generation and storage. It holds stakes in the Yandin Wind Farm (WA’s largest) and is constructing a 100 MW battery at Wagerup.
Its “True Power” campaign aims to educate Australians about the ongoing energy transition, emphasising their commitment while acknowledging the gradual phase-out of fossil assets.
ENGIE Australia
ENGIE is among the world’s top renewable operators, with solar, wind and hydro assets. In Australia, it offers REGO-backed green power contracts to business clients, but residential-level renewable enhancements are not yet widespread.
Residential customers do not currently have access to branded GreenPower options, though the company’s parent business is heavily committed to decarbonisation and electrification strategies globally.
