This project is about how electricity distributors and direct connect consumers provide extended reserve using automatic under-frequency load shedding (AUFLS).
The Authority is proposing to change the requirements for how participants provide extended reserve in the North Island using AUFLS.
AUFLS are the blocks of load that are automatically disconnected during large under-frequency events in the electrical system. Although AUFLS is currently the only type of extended reserve product used in New Zealand, the Authority has adopted the generic term – extended reserve – to not limit the future introduction of other products and services.
The Authority expects the proposed revised Extended Reserve scheme to deliver a more flexible and resilient electricity system for consumers by reducing the likelihood of New Zealand-wide black-outs.
