Australian body finalises rules on wind and solar output

Australia’s electricity rules maker Australian Energy Market Commission (AEMC) has finalised a new rule preventing wind and solar projects from cutting output without prior notice to avoid negative wholesale electricity prices.

The rule will be effective from 12 April. Wind and solar projects will be required to generate electricity at an output level advised by the Australian Energy Market Operator (AEMO) and can only fall below that output when wind and solar conditions change.

If a wind or solar generator wants to reduce its output, it will first need to inform AEMO and await a revised instruction.

The Australian Energy Regulator (AER) proposed the change in 2020. It said the rule change would maintain a stable supply of electricity and minimise changes in output from the growing number of wind and solar projects.

The move is supported by the Clean Energy Council.
