Executive summary of update This update introduces significant regulatory changes across three key areas. Firstly, it establishes new rules for solar-generated electricity, mandating that retailers and exempt sellers cannot charge customers for exported solar energy and must credit them at a rate no less than $0 per kilowatt hour. Secondly, it substantially increases the financial penalties for licence breaches and expands the regulatory powers of the Independent Pricing and Regulatory Tribunal (IPART), including the ability to institute proceedings under the National Electricity Law for specific rule breaches.
