Update July 2022

Ancillary Services Charges (including RERT Recovery Charge for NSW and QLD Customers)

Ancillary Services are used by AEMO to manage the power system safely, securely and reliably. Related ancillary service costs are dependent upon the amount of service required at any particular time.

In June 2022, following a period of prolonged high spot prices, AEMO capped the spot price at $300/MWh. A few days later, AEMO suspended the spot market and began directing generators to run to ensure a secure and reliable supply of electricity for consumers. These interventions by AEMO are considered Ancillary Services and the associated costs are passed onto retailers.

During the same period, AEMO deployed the RERT mechanism in Queensland and New South Wales to maintain grid stability and avoid power outages. Through RERT, some electricity consumers are paid to power down their sites. AEMO passes the cost of paying consumers that were able to power down onto retailers.

As such, the Ancillary Service charge on your invoice has increased in June 2022. A credit and rebill will be applied once actual costs are known, including a one-off AEMO RERT Recovery Charge for Queensland and New South Wales customers (expected July 2022).

Update March 2022

There will be a one-off charge for Queensland customers on their March invoices.  

What is the change to Queensland energy customers’ charges in March 2022?

We’d like to advise our customers that during February 2022, electricity prices in Queensland were elevated, particularly on 1st of February.  

Due to this, Queensland customers will have a one-off charge on their invoice called AEMO RERT Recovery Charge – QLD which relates to your site’s consumption during the RERT event on 1st February 2022.  

Why is there a one-off RERT recovery charge? 

Due to consecutive days of high temperatures (increasing demand) and then further exacerbated by low availability of thermal generators (reducing supply) resulted in the elevated prices experienced in Queensland. 

Unfortunately, several Queensland thermal generators were unavailable due to scheduled and emergency maintenance. 

This resulted in the Australian Energy Market Operator (AEMO) deploying the Reliability and Emergency Reserve Trader (RERT) function

In extreme instances of pressure on the grid, AEMO uses RERT to maintain power system reliability and system security using reserve contracts. 

Through RERT, some electricity consumers are paid to power down their sites. AEMO passes the cost of paying consumers that were able to power down onto retailers who typically collect it from their customers.

Update February 2022

What are the changes to energy customer charges in February 2022?

The Clean Energy Regulator (CER) has declared that the 2022 surrender percentages for the Large-Scale Renewable Energy Target (LRET) and Small-Scale Renewable Energy Scheme (SRES) are:

  • LRET = 18.64% (0.53% increase from 2021)
  • SRES = 27.26% (5.64% decrease from 2021)

Why are LRET and SRES surrender percentages changing? 

The LRET and SRES initiatives aim to incentivise the development and installation of large and small scale renewable energy projects, like large-scale wind and solar farms and small-scale solar on residential properties.

The Clean Energy Regulator (CER) requires electricity retailers to procure and surrender certificates generated from qualifying projects, to support these initiatives. This charge is passed on to customers in their monthly invoices. 

Who will this change affect? 

This change will affect customers with fixed certificate prices only. 

What change will you see on your invoice? 

On your February consumption invoice (issued in March), there will be a rebilled line item called ‘Credit Rebill for updated LRET and SRES surrender percentages’.

The reason for the rebill is that the 2022 surrender percentages were unknown at the time, so Flow Power used the 2021 surrender percentages.

March 2020 – AEMO RERT charges

To make sure the lights stayed in summer 2020, AEMO worked with retailers and energy users to set up the RERT. Many Flow Power customers were involved in the program that paid users to reduce their demand on the grid during peak times.

AEMO called on energy users across the National Energy Market to power down in line with market events this summer.  You can read our recap of the summer here. A number of Flow Power customers reduced their demand on the grid to help to manage their costs and support the system.

Those customers who participated received a RERT payment from AEMO, which shows as credit line item on your monthly invoice.

The AEMO RERT program is paid for by all energy users. Customers see a line item amounting to the portion of the RERT cost on invoices.

March 2020 – FCAS and Direction charges (SA&VIC only)

On January 31 2020, extreme weather saw a tornado down high-voltage transmission lines in Victoria, disconnecting the main interconnector between South Australia and Victoria.

This effectively islanded South Australia from the rest of the National Energy Market. While energy prices in the wholesale market were low, being islanded from the grid limited South Australia’s capacity for Frequency Control Ancillary Services (FCAS).

In South Australia, FCAS can only be supplied by gas generators and the Hornsdale Power Reserve. As gas units don’t usually run, when they do it’s more expensive. This pushed FCAS prices much higher than normal. Typically, FCAS charges are only a small portion of your electricity bill. However, during this event FCAS prices were much higher than normal; they breached the Cumulative Price Threshold requiring AEMO to step in and cap  the price at $300/MWh.

Additionally, AEMO issued directions to specific generators requesting them to run when they normally wouldn’t, in both South Australia and Victoria. This also adds cost that must be recovered from the market.

You will see a charge to cover your share of FCAS and Direction charges passed through by AEMO.

February 2020 – Environmental certificates

In CY20, the surrender percentage of STC and LGC increased provisionally by 2.5%. The LGC and STC rates on bills were reflective of this.

There was also an increase in VEEC (Victorian Energy Efficiency Certificate) charges for Victorians. This was due to changes made in the Victoria Energy Upgrades programme which resulted in less VEEC creation and higher spot prices.

March 2019 – AEMO RERT

To make sure the lights stayed on in summer 2019, AEMO worked with retailers and energy users to set up the RERT. Many Flow Power customers were involved in the program that paid users to reduce their demand on the grid during peak times.

AEMO called on users in SA and Victoria on January 24 and 25 to power down in line with a market event. For the second year running, Flow Power customers reduced their pressure on the grid by 50% – helping to manage their costs and support the system. Those customers who participated also received a RERT payment from AEMO, which showed as credit line item on customer’s monthly invoice.

The AEMO RERT program is paid for by all users and customers will see a line item amounting to your portion of the RERT cost on your invoice this month.

February 2019 – Update on Powercor distribution charges

Are you based in Western Victoria? If so, you’re probably in Powercor’s distribution network.
This month, you might see an adjustment line item on your bill. Let us breakdown what this is.

On November 23, 2018 Powercor changed the way it charged for losses on parts of its network, adopting a lower-cost losses code. The lower cost was applied retrospectively from September 24, 2018 onwards.

While we passed the lower price onto impacted customers, you wouldn’t have noticed a credit on your previous bills, as the credits were held by AEMO.

On February 19, 2019, Powercor reverted back to its previous losses code, re-applying the higher changes retrospectively from September 24, 2018 onwards – again. Under its rules of operation, this is possible.
So, what does this mean for you?
Between November 23, 2018 and February 10, 2019, we billed impacted customers at the lower rate for network losses. Based on the latest changes by Powercor, we now need to re-calculate and charge the difference as an adjustment to impacted customers on their February bills.
(Please note, Flow Power passes through network charges at cost).

July 2018 – Updates to AEMO Pool Fees

Who thought the government would ever remove a tax? Well they have. As of 1 July 2018, AEMO Pool Fees no longer attract GST. This will be reflected in all Flow Power bills

April 2018 – Updates to AEMO Emergency Reserve Trader charges (SA & VIC only)

To make sure the lights stayed on this summer, AEMO worked with retailers and energy users to set up the RERT. Many Flow Power customers were involved in the program that paid users to reduce their demand on the grid during peak times.

AEMO called on users in SA and Victoria on January 19 to power down in line with a market event. Flow Power customers reduced their load on the grid by 50% – helping to manage their costs and support the system. Those customers who participated will also receive a payment from AEMO, which will show as a new invoice credit line item on the bill.

All customers will see a new line item that is your portion of the RERT cost on your invoice this month.

We are working with AEMO to understand the best way to manage these costs for you.
