High temperatures across the eastern states is increasing electricity consumption levels in South Australia and New South Wales, placing additional strain on the national power system. This has resulted in reduced generation reserves within these two states.
Experiencing some of the highest electricity demand ever recorded in the state, South Australia experienced local load shedding on 8 February 2017, and AEMO has released a market notice today to notify generators of a forecast potential shortfall in New South Wales for Friday, 10 February 2017 from 17:30 AEDT, should the market not respond.
AEMO is in discussion with a number of generators within New South Wales and the New South Wales government to mitigate the need for local load shedding. Load shedding can sometimes be required when there is an imbalance between electricity demand and electricity supply. When there is a shortfall in the electricity supply, there can be a need to reduce demand very quickly to an acceptable level, or risk the electricity network becoming unstable.
Under the National Electricity Rules, AEMO has authority to implement emergency rotational load shedding during power system emergencies to ensure the system remains secure and to avoid prolonged power outages.
Load shedding arrangements vary from state to state, but the objective of rotational load shedding is to minimise the impact on any one group of customers. Sometimes rotational load shedding is not an option – for example, if the supply-demand balance changes rapidly, then load shedding can happen almost instantly.
If consumers can safely reduce their electricity consumption during periods of high demand, this can ease the supply/demand balance and can mitigate the need for load shedding.
The safety of the community is the energy industry’s number one priority during power system emergencies, and AEMO is working closely with industry to restore and maintain reliable, secure electricity supply to affected regions in the National Electricity Market as quickly as possible.
