Synergy Announces WA Electricity Price Increase from July 1st 2021


The Western Australian State Government, in association with Synergy, have recently approved price increases to specific residential and business electricity tariffs. Synergy announced that the changes will come into place on the 1st July 2021 and will see electricity prices increase by 1.75%, meaning West Aussies will soon be forking out even more on their power bills.

Now, you might be thinking that 1.75% isn’t much… and you’re right. However, according to the Australian Energy Market Commission, the annual electricity bill for a typical residential customer increased from $1,566 in 2017/18 to $1,769 in 2019/20. That’s an increase of $203 in just two years. Furthermore. this new increase, the annual electricity bill for a typical residential customer is set to jump up to just over $1,886. That’s another noticeable increase, this time by $117 in just two years.

How Can I Make My Power Bill Cheaper?

It’s normal to be wondering how you can reduce the cost of your power bill when the prices just keep increasing. One way you can do this is through making the switch to solar… and in terms of sunshine, WA is blessed. According to the Australian Bureau of Meteorology, Perth sees a daily average of 8 hours of sunshine, and the amount only increases as we move further up the coast. Additionally, Albany, Esperance and other areas south of Perth even get a minimum of 6 hours of sunshine each day on average. We’d even go as far to say that WA is giving Queensland a run for its money when it comes to being known as the sunshine state.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
