How can I save power?
No cost
- Keep windows, curtains and blinds closed during the day to stop the summer sun from getting into the house
- At night time, open windows and blinds to let hot air out and cool air in. If you have west facing windows, open them in the late afternoon to let the sea breeze in
- At the start of summer, clean the filters in your air conditioner. This means your air conditioner won’t have to work as hard when cooling your house
- Before turning on the air conditioner, try using a fan, you could save up to $200 a year
- Keep your air conditioner setting at 24 degrees – every degree lower you set your air conditioner can significantly affect running costs during the summer
- Keep the doors to the room you’re trying to cool closed when using the air conditioner. This prevents cool air from escaping and the air conditioner isn’t cooling rooms you’re not using
Low cost
- Put some shade cloth over your east and west facing windows. This will stop some of the sun before it hits your windows and heating up your house
- Plant deciduous trees/ bushes on the western and eastern sides of your house. These will block summer sun but let winter sun through
Higher cost
- Install roof insulation. This will prevent heat entering the house but also the cool air from your air conditioner escaping
- Install 'whirly birds' or roof ventilators on your roof. This will remove hot air from the roof cavity, helping keep the house cool
No cost
- Set your heater or thermostat to between 18 and 20 degrees, as every degree warmer can increase your running costs by up to 10%
- When the temperature starts to drop, grab a jumper, some woolly socks or a blanket, instead of reaching for the heater or turning on your electric blanket
- Adjust your storage hot water system from 80°C to 60°C
- Close your curtains at night to trap the heat inside and check there are no drafts entering under doors or through cracks
- When you have the heater on, keep the doors shut and windows closed so the warmth stays in the room
Low cost
- Even a small 1200W bar heater can chew through a dollar every four hours. Reduce the heat loss from the room by using a more efficient product, like a high-star rated reverse-cycle air-conditioner or an oil heater with a thermostat that turns off the heating once a set temperature is reached
- An uninsulated ceiling means you could be losing up to 45% of your heating through the roof

Western Australia’s electricity use continues to grow, especially during peak periods. The term peak demand refers to the times of day when as a community our electricity consumption is at its highest. In addition, Western Power understands the rising cost of electricity is being felt by many households. By working together as a community to reduce our electricity use, particularly during peak periods, we can help to ensure a reliable and affordable supply for everyone.
Reducing your electricity use brings a number of benefits:
- Saving money:
- reducing your power bills
- in the long term by reducing the need for more generators and network infrastructure (costs which get passed onto customers)
- It reduces greenhouse gas emissions which contribute to climate change. While renewable sources of energy, like wind, play an increasing role in our system, the vast majority of our electricity is still generated from fossil fuels like gas, oil and coal. Reducing our electricity use reduces the flow of carbon dioxide into the atmosphere.
Small changes to the way we use electricity can make a big difference.
- Turn off your second fridge and save up to $200 a year
- Turn off standby power and save up $150 a year
- Replacing your old incandescent lights with CFLs could save you up to $165 a year
- Replacing 10 downlights with 10 LED lights could save you up to $150 a year
- Adjusting your storage hot water system from 80 degrees to 60 degrees could save you up to $70 a year
- During summer and warm weather, try not to use your clothes dryer and save up to $95 a year
- Washing your clothes in cold water could save up to $40 a year
- Reducing washing machine and dishwasher loads by one each week, and only washing will full loads could save you up to $50 a year
- Two family members reducing their shower time from 8 minutes to 4 minutes could save up to $170 a year
- Make sure you don’t use your pool pump longer than is recommended in the operation manual. When you do use your pool pump, try to avoid the peak electricity use period of 4pm to 8pm
Before you leave don’t forget to:
- Turn your electrical appliances off at the wall – leaving your appliances on standby still uses electricity
- Turn off timers – if you have any appliances (including your air conditioner), on a timer make sure you don’t waste electricity and money by leaving them on when not needed
- Switch off the second fridge – if your second fridge is only used for keeping drinks cool, turning it off when you’re away is a simple way to save electricity
When you’re on holiday it’s easy to be energy efficient:
- When you go out switch off the air conditioner - closing curtains and blinds will block out the hot sun and keep it cool inside without wasting electricity
- Keep up your good energy saving habits – remember to not leave lights on and appliances on standby before you head out for the day
- Beat the peak between 4pm and 8pm – if you’re staying in a holiday home help beat the peak by using major appliances (e.g. dishwashers and washing machines), outside of these hours

The cost of electricity has risen sharply in recent years. If you are experiencing financial hardship and cannot pay your power bill, help may be available.
The State Government offers rebates and concessions which provide financial assistance to eligible households.
What is peak demand?
Peak demand refers to the times of day when our electricity consumption is at its highest.
Annual peak demand occurs in summer during prolonged heat waves, usually between 5pm and 9pm when most people arrive home and switch on their air conditioners, TVs, lights and other household appliances. Air conditioner use amounts to nearly one third of the power consumed on the hottest days in January, February and March.
The peak demand during winter occurs on very cold weekday evenings when people heat their homes. Winter peak demand is slightly lower than summer peak demand, but has a significant impact in some areas of the network.
In the event of multiple days of high demand, we’ve several measures in place to proactively manage this. We cancel planned works where necessary, and in the event of unplanned outages we stand-up additional customer support staff, network controllers and ensure all available fault and repair crews are ready.
Community and crew safety is fundamental. We're mindful of re-energising around vegetation to mitigate bushfire risk as our network infrastructure traverses a lot of urban bushland and parks. Work in one area of the network can still cause a spark some distance away. So high fire weather conditions mean we’re restricted in our ability to locate faults and restore power.
Each peak demand events provides us with additional insight and vital new data that helps us plan equipment upgrades and reconfigure system settings to allow for extra flexibility in areas of unprecedented high demand.
When the temperature remains high into the evening and customer demand is sustained, our network infrastructure doesn’t have a chance to physically cool down. This can result in an increased risk of faults and localised outages.
During peak energy hours, you can help by shifting your energy use and reducing power consumption. Every small change adds up, as well as save you money on your electricity bills. You can help by:
- Using your high energy appliances outside of the peak hours between 5pm and 9pm
- Setting your air conditioner to 24 degrees in hot weather and 20 degrees in cooler weather
- Running your dishwasher and washing machine in the morning avoiding use between the hours of 5-9pm
- Using your pool pump in the middle of the day
- Turning off appliances at the wall as they still use power on standby
- If you have solar power, setting your timer to run appliances in the middle of the day to get the most from the sun
We're building a modular grid of the future that will lead the way to a cleaner, brighter and more resilient energy supply.
We’re transforming the network to enable our customers to better harness batteries, rooftop solar and electric vehicles, which offers more choice in generating, storing, and using energy. The growing adoption of these devices is expected to help manage power demand by enabling households to have greater control over when and how much electricity they consume.
We’re continuing the roll out of our Advanced Metering Infrastructure which gives us greater insight into power usage across the network, enabling us to enhance our forecasting and refine where we target our investments to improve reliability.
Heatwaves are considered three or more consecutive days of unusually high temperatures. Both temperatures and electricity demand tend to rise in the third and fourth days of consecutive hot days, as air conditioners increase output to manage the accumulating heat inside buildings.
The grid works hard during heatwaves. The combination of high electricity demand and high temperatures can impact the operation of key infrastructure like generators and transmission lines, increasing the risk of localised outages.
Electricity supply can be interrupted due to faults or heat-related strain in a generator (or generators), or when a transmission line capacity is reduced to avoid equipment damage resulting from high temperatures or shut off because of the risk of bushfires.
Localised unplanned outages are an interruption to the transmission or distribution of electricity that is unscheduled and can occur as a result of range of causes including: damage to wires caused by storms, lightning strikes, falling trees or branches, motor accidents, bushfires, equipment failure and high demand (overloading).
They can involve a handful or hundreds of homes and businesses depending on the cause, and supply is restored once repairs take place.
New connections
Sometimes your circumstances change and you may need to cancel or change the information within your application after you have submitted it to us.
If you wish to change the scope of work in your application we will first review the change and then either:
- continue the project with the variation and invoice you for any additional materials, design work and remobilisation costs incurred. We will typically only take this approach when the change is very minor.
or
- if the change is significant we will cancel your project. You will need to submit a new application with your new requirements.
For cancelled applications we will invoice you for the costs incurred up to the point of cancellation (time and materials). If construction work has already commenced we will refund the difference from your access offer less any costs incurred.
We use thresholds to help determine ‘competing’ load applications as part of our Applications and Queuing Policy (AQP). Thresholds are currently defined by demand values for a given load area or network region.
Following a review of the threshold levels in June 2014, we revised our ‘Non-Competing Application Thresholds’ test and will now only consider new load applications which meet the following two criteria to be non-competing for the purpose of the AQP.
- The total load must not exceed 1.5 MVA for its National Metering Identifier (NMI), and
- The load application must be eligible for network tariffs RT1-RT6.
Customers on network tariffs RT1 – RT6 best represent customers that are considered part of ‘natural load growth’.
The revised ‘Non-Competing Application Thresholds’ test will apply across the South West Interconnected Network (SWIN) from September 2014 and replaces all previous thresholds identified in our 2013 Annual Planning Report. This amendment will ensure there are consistent thresholds across the SWIN.
All load applications deemed to satisfy the two revised ‘Non-Competing Application Thresholds’ test criteria will be granted firm access to the SWIN. All other load applications will be subject to a Competing Applications Group if there are multiple applications behind a common network constraint, or as part of an Applicant-Specific Solution process.
Strata schemes typically have a single connection point to the Western Power network that determines the total allocation of available electricity supply and generation capacity to be shared by all strata lots.
This connection point has a fixed capacity, so it's important for strata lot owners and prospective purchasers to be aware of the arrangements and obligations relating to the connection, as it may restrict their ability to install equipment such as home EV charging stations, rooftop solar panels and batteries.
Before applying to connect this type of equipment, strata lot owners should first seek permission from their strata company to use an allocation of the total network capacity allocated to the strata scheme.
Failing to do this may prevent other strata lot owners from connecting their own equipment, or require the strata company to upgrade the connection to the Western Power network to accommodate the needs of all strata lot owners.
It's important to remember that the strata company is ultimately responsible for the management of the common connection to the Western Power network and the common electrical system within the strata scheme. Effective management of this shared resource will allow the benefits of renewable energy solutions to be shared by the all strata lot owners.
More information about strata titling principles can be found in Landgate's Guide to strata titles.

Western Power is regulated by the state government in terms of how it can earn revenue. Our revenue (through tariffs) is determined by the size of our Regulated Asset Base (RAB).
When streetlights are added to the RAB they have an economic life of 20 years. If a streetlight is replaced or upgraded to LED lighting when it is younger than 20 years old, there’s still some value in there that we haven’t recovered back yet.

The terms used in these conditions have the same meaning as in the Western Australian Service and Installation Requirements 2021.
1. Approval is void should the application details be subsequently found to be invalid.
2. The approved system must:
- not be connected after the expiry date recorded on the approval
- be connected via a Western Power approved import/export meter
- be installed as detailed in the approved application (including diagrams) and, if special operating
conditions are applied, to comply with the conditions before commissioning - have switches/breakers installed to legislative and network operator requirements
- be designed for a maximum voltage rise within the installation of less than 2% or 4.8 V as per
AS/NZS 4777.1:2016 - use CEC approved products with compliance to extra requirements of volt-watt, volt-var,
IEC 62116, VDRT (new equipment) - comply with Western Power’s Basic and LV EG Connection Technical Requirements
3. All electrical installation, commissioning and maintenance work wherever required must be carried
out by an electrical contractor licensed under the Electricity (Licensing) Regulations, 1991.
4. Western Power may inspect the installation from time to time to ensure continued compliance with
these requirements. If we consider that the installation poses a threat to safety, to quality of supply,
to the integrity of the distribution system or does not conform with Western Power technical
requirements we may disconnect the equipment.
Your connection point has a fixed capacity. If it is shared with other customers, potentially multiple new systems could be added and exceed that capacity. This can make it unsafe and unreliable.
Shared connections must be managed to ensure that all customers have access to a safe and secure electricity supply as well as the opportunity to connect to benefit from renewable energy solutions.
Before applying to connect this type of equipment, tenants or owners with shared connections should first seek permission from their strata company or management body to use a portion of the total network capacity allocated.
Failing to do this may prevent others from connecting their equipment, or require the management body to upgrade the connection to our network to accommodate the needs of all owners and or tenants.
It's important to remember that the strata company or management body is ultimately responsible for the management of the common connection to the network and the common electrical system. Effective management of this shared resource will allow the benefits of renewable energy solutions to be shared by all.
More information about strata titling principles can be found in Landgate's Guide to strata titles.
Shopping centres, commercial tenancies, strata schemes and other grouped properties typically share a single connection point to our network that determines the total allocation of available electricity supply and generation capacity to be shared by all lots.
This connection point has a fixed capacity, so it's important for tenants, owners and prospective purchasers to be aware of the arrangements and obligations relating to the connection, as it may restrict their ability to install equipment such as home EV charging stations, rooftop solar panels and batteries.
The revenue meter is required to be changed or reconfigured to measure bi-directional energy flows (import – export meter registers) before the connection of the embedded generation system. Please contact your electricity retailer before applying to Western Power for technical approval of your proposed system.
If a sub-meter is associated with the connection point at which bi-directional flows will occur, you may wish to engage a licensed electrical contractor to change the sub-meter and make the necessary arrangements with you at the revenue meter.
If bi-directional flows will occur at a sub-meter the measurement of energy flows is at the discretion of the customer. You may wish to engage an electrical consultant or contractor for energy management options.
Common sub-metering arrangement
The diagrams below illustrate typical revenue meter and sub-meter configurations.
Residential property with granny flat
Apartment buildings and shopping centres
Power station
Note: SPD means Service Protection Device.
Your connection will either be an individual connection or a shared connection.
Each connection has a ‘generation allocation’, or amount of solar, it can accommodate.
When you make an application to us to connect solar PVs our system will show whether the connection for the given address is individual, shared or unknown. The connection type is important to us for assessing the application.
- Individual connections have their own connection and generation allocation.
- Shared connections share a connection and generation allocation with others in the same development.
- Unknown means we must review to resolve which connection type it is.
These diagrams illustrate common connection types.
Individual connections
Individual underground connection
Individual connection with an overhead service cable
Individual connection with an overhead service cable and customer poles
Shared connections
Units in developments such as strata schemes, shopping centres and residential parks connect through a switchboard to the grid.
Sometimes in small older developments, units connect directly to the connection point. However, all units still share the generation allocation.
Shared underground connection
Shared connection with an overhead service cable
You need Western Power approval if:
You are installing a new solar system, or relocating an existing solar system, or changing or upgrading an existing system or replacing an inverter.
But if you are doing like-for-like maintenance work or only changing PV* panels, then no application is required.
Like-for-like maintenance work means it has the same maximum power rating, same phase, same quantity and/or has a Western Power approved battery (current CEC approval and volt var, volt watt, IEC 62116).
For all other work you will need to apply via our application page.
Please note - if you have a three phase connection and are replacing a single phase inverter with one greater than 3kVA, you now need to apply for approval. This is because, the new inverter will not operate at optimal efficiency.
*PV stands for Photovoltaics otherwise known as solar panels
Stratas, lifestyle villages and other multi-residential sites usually share a single connection to the grid. These properties can have tens or even hundreds of homes behind a 'shared connection', which means that the combined total of installed solar generation can easily pass the 30kVA limit. Above this limit an installation needs to comply with more complex connection requirements and higher costs associated with the larger (above 30kVA) application.
To allow residents of such sites to take advantage of solar power an exemption is available to the land-owners or their representative e.g. the strata management company, of multi-residential sites to allow these sites to contain up to 500kVA of generation without incurring the fees associated with a larger application.
This exemption is applied for by the land-owners of the site or their representative.
How this may affect your application:
- If it's predicted that the site will exceed 30kVA of aggregated embedded generation, the land-owners of the site or their representative should apply for a Multi-residential exemption as soon as possible
- Once the site has exceeded 30kVA, the technical exemption will be required before any further solar applications can be processed and you may need to quote the exemption identification number during your solar application
- An approved exemption will describe a maximum amount of solar that can be installed at a site, how this allowance is shared among residents of the site is the responsibility of the land owners or their representative – you will need to check with them before applying
- Within the exemption, individual homes can have up to 5kVA of generation but the land-owners or their representative may advise that a lower limit needs to apply
Multi residential land-owners
- Further technical information is available on the Multi-residential exemption application form
- This application requires the certification of a suitably qualified registered electrical engineer.
Find an engineer via the National Engineers Register or contact Engineers Australia for more information.
See also: Do I need permission from my strata company before applying for my connection?
Residential applications can only be approved up to 30kVA.
In small strata situations – where 2-4 homes can sit behind a single connection - it is possible that your neighbours have already installed enough generation that the amount you requested is not available. You will need to apply for a system with a limit that works within the remaining amount.
In larger stratas: lifestyle villages or residential developments, the land owners of the multi-residential site or their representative e.g. the Strata management company may need to apply for an exemption to allow residents to connect solar systems. You will need to talk your property manager to move forward with your plans.
No. This is not a service that Western Power offers. If you are thinking about getting solar panels installed refer to our article what to look for in a reliable solar installer in Perth
If you have installed a different inverter make and model to that shown in the EG Preliminary Approval to Connect, you can update the inverter details in the EG Registration form.
- Step 1 - Go to ‘Update Inverter Details’ and follow the prompts to enter the information of the installed inverter.
- Step 2 – Go to ‘Enter Serial Number(s) and enter the Serial Number of the installed inverter
All inverter brands display a unique serial number format. This format is a combination of alphanumeric numbers and characters of varying lengths and structure.
The Serial Number field validates to the exact format associated with the selected inverter.
Below are examples of the correction formatting
Example #1
If you have installed a Fronius inverter then the serial number format must be a total of eight numeric characters and the first number must be a "2" or "3". For example: 21234567
Example #2
If you installed a Growatt inverter, the first three characters must be alphabetic, followed by seven alphanumeric characters. For example: ABC123456A

Connection
The connection of an underground cable from a power pole to a pillar near the front of your property is known as an underground connection. You need to organise an electrical contractor to install a mains cable from the pillar to your meter box to complete the connection.
Running an underground cable from the pole in the street to your property is commonly referred to as a pole to pillar connection. Depending on which side of the road the powerlines are, this may involve drilling under the road. A pillar is then installed inside your property, close to the side and front boundaries. You need to organise an electrical contractor to install a mains cable from the pillar to your meter box to complete the connection.
You can keep an overhead supply when: you have an existing overhead electricity supply to your house, you only require a standard electricity supply, you can meet all the relevant safety requirements, such as clearances near swimming pools, etc., and your power connection has not been abolished (if your power supply has been abolished then you need to apply for a new connection). All new electricity connections and their associated connections must be undergrounded (there are some exceptions in rural areas). New connections can be requested via the Residents tab in new connections.
When subdividing a block you are introducing a new connection to the electricity network so this and all associated connections must be underground.
To connect into an existing pillar you need to submit an application for a new residential connection. Western Power will determine if any additional works are required to connect and provide you a quote. In most instances the only costs will be for a ‘disconnection/reconnection’ service for Western Power to come and terminate your consumer mains.
If you plan to demolish a property, and need the power disconnected and removed so the work can proceed safely, then first speak to your retailer to have your meter removed.
Your retailer will request us to disconnect the power. We generally remove your meter and connection within 10 business days.
- For overhead supply we remove the meter and overhead service cables
- For underground supply we remove the meter. You must arrange to have the underground cable between the pillar and the building removed.
In certain circumstances, your retailer will request you complete the Connections, Disconnections and Metering form.
This will apply if you have a complex CT meter and to specific properties located in the CBD.
Western Power has completed work in your area. Power can be reconnected to your property once you (as the home owner or resident) have checked for any additional steps that you may need to take.
When you can return to your home, you need to look for a tag or notification on the status of your electricity supply. This will be placed in the meter box, or at the front door if there isn’t enough space in the meter box for the disconnection tag.
If the tag says Temporary disconnection the homeowner or other person in charge must arrange for an electrical contractor to complete the required works. Once all of the defects listed have been fixed your supply can be reconnected. If you still do not have power after your electrical contractor has completed the required works and provided the relevant information to Western Power, please call us on 13 13 51.
If the tag says Information | Caution your connection can be reconnected to the network when power’s been restored. Once connected, you can flick your main switch to ‘On’.
In all circumstances, if your home has been affected by fire, we recommend that you get a licensed electrical contractor to check the integrity of the electrical installation in your property.
For your safety when network power is restored, the electrical inspector advises that you conduct a visual safety check on all external electrical equipment (including bore pumps, power points, external ground lighting) within your property prior to turning it on. If you find any damaged electrical equipment you must contact an electrical contractor to have the problem fixed.
Power fluctuations may occur when power is restored, so it’s helpful to unplug sensitive appliances before reconnecting. When reconnected, turn on appliances one at a time, starting with lights and small appliances. If you experience any shocks, zaps or tingles report them immediately on 13 13 51.

Extended outage payment scheme
We recognise day-to-day living has been impacted by power outages caused by the 2021 Wooroloo bushfire. To provide further community support for customers impacted by this bushfire event, either directly or indirectly, the extended outage payment has been doubled from $80 to $160.
We administer this payment, and if you’ve experienced an extended outage (12 hours or more) from these fires, you can apply once power is reconnected for the extended outage payment online.
Reconnection fees
Where property or network connections have been have been damaged but not destroyed by the fire, reconnection of existing customers points and meters will be free of charge.
For residents whose property has been destroyed by the fire, we’ll be waiving the cost of establishing a temporary builder supply (if required) and any network-side reconnection fees.
For more information please contact us on 13 10 87 between 8.30am and 5.00pm.
Connection point changes
Some common examples of actions resulting in a change to the connection point include:
- a meter is removed, or a new one is added.
- a current transformer is being added or removed.
- the status of the revenue meter is changing for example will be converted to a sub-meter or an embedded network is being installed.
- the connection is changing from low to high voltage or vice versa.
If a customer doesn’t know if the connection point will change, Western Power can assess and advise as part of the application process.
The retailer is responsible for each connection point where electricity is supplied to their customer using the Western Power network, so they need to know what's going on.
To approve a customer's request to change the connection point, we need to be advised by the retailer what change its permitting.
If the retailer doesn't get involved, we’re not able to process the customer's application beyond the design stage.
Western Power will place the application on hold for a set period and ask the customer to contact the retailer.
We’ll provide each customer with a unique reference number related to their application. This number allows us to track the project and respond to any enquiries.
The customer should keep this number – it's important and we'll always ask for it. It's also the reference number that will need to be provided to the retailer.
When the retailer provides their approval, they will quote this number so we can match it to the customer's application.
Before construction starts, Western Power agrees the scope with the customer, we understand however that sometimes, plans change. If the scope changes, we need to assess what these changes involve.
If this work modifies the connection point, the retailer will need to get involved.
Emergency Solar Management
Yes, there are changes to electrical wiring for meter control only. Please refer to the Distribution Customer Connection Requirements and the video below
Emergency Solar Management only applies to the South West Interconnected System (SWIS).
Customers not eligible for Synergy DEBS or REBS are excluded from Emergency Solar Management control requirements.
Licensed electricians are required to do this work. They have the skill and ability to review an electrical installation and where necessary access electrical switchboards to determine required work. It is illegal for unqualified workers to perform electrical work.
There's no cost to the customer for the dual element meter unit. The cost for solar installation with meter control method depends on site conditions.
No, a second AMI meter can't be used.
As outline in the Distribution Customer Connection Requirements, the following choices are available for meter control where single phase export limiting or energy monitoring are provided as an option:
- Monitoring measures load only.
- Monitoring measures the net load and generation.
All installations must comply with the Basic EG Connection Technical Requirements and the manufacturer’s requirements.
Yes, the main switches will need to be circuit breakers.
We’ve created training assets to assist solar installers prepare the site for Western Power:

Western Power will not switch the inverter system on but will leave a ‘Meter Service Work’ card in the letter box after the work has been completed. The electricity retailer will email the electricity account holder when they can start the system and commence generating.
The entire system would need to meet Western Power's connection technical requirements for the new battery components and the existing system must be compliant with settings at time of original installation. In this situation, the applicant is not subject to ESM requirements.
The electrician installing the system is permitted to temporarily connect the system to test, commission and set up for API cloud solution. The inverter must be isolated (switched off) at the main switch inverter supply following these steps.
A general power outage will cause the PV inverter to shut down its output to the grid. They're designed for this and all the control settings will be restored when switched back on. We don't expect any troubleshooting will be required when power supply returns.
Do we need an inverter energy meter for systems with an inverter up to 5kW? Inverter energy meters (to monitor consumption and export) are required by Western Power, when an export limit is specified during the application process, typically for all systems 5kW and above to manage the export limit operation. Inverter energy meters are also often used for system less than 5 kW on small networks where a site has a limited export. Some consumers find it useful to add inverter energy meters for load monitoring to manage the energy generated from their solar systems even when no export limit is specified.
The export limiting device can be set up in the sub-board for the house or individual user, provided that both the load and generation are monitored and generation can be reduced so that the export amount is equal or less than the limited for the site.
Load shedding
Load shedding is a last resort response by the Australian Energy Market Operator (AEMO) to maintain system stability and security, mitigate damage to infrastructure and to protect customer equipment.
Under the instruction of AEMO, Western Power will undertake manual load shedding by deliberately shutting down power to parts of the electricity network to reduce a predetermined volume of electricity usage to maintain system stability and the supply-demand balance.
Australian Energy Market Operator (AEMO) determines how much power needs to be reduced to maintain system stability.
When power demand needs to be reduced AEMO instructs Western Power to deliberately shed load. We initiate a process of rotational controlled outages (typically 2-hours). Areas are pre-determined to minimise the impact on the community, particularly major health facilities, life-support customers, emergency services and public transport. However, these services can still be affected and should have business continuity arrangements in place.
Australian Energy Market Operator (AEMO) determines how much power needs to be reduced to keep the electricity system stable and has instructed Western Power to shed load on a rotational basis. This happens very quickly and is dynamic in delivery which means we’re not able to provide pre-outage notifications to those affected. If you’re affected, we apologise for the inconvenience this may cause and encourage you to visit our power outages information to keep-up-to date on estimated restoration times. Each outage is expected to last up to two hours.
The power system may experience different types of power outages. Load shedding is different to local outages (planned or unplanned).
Load shedding is a last resort response by the Australian Energy Market Operator (AEMO) to maintain system security, mitigate damage to infrastructure and to protect customer equipment. It’s the controlled reduction of electricity supplied to homes and businesses to securely manage the wider power system.
Planned outages are undertaken by Western Power and are prearranged and necessary for routine maintenance, inspections and improvements on various electricity infrastructure.
Local unplanned outages are an interruption to the transmission or distribution of electricity that is unscheduled and can occur as a result of range of causes including: damage to wires caused by storms, lightning strikes, falling trees (or branches), motor accidents, bushfires, and equipment failure.
