Peter Anderson jokes that he is allergic to paying electricity invoices.
This motivated him to have solar panels installed at his residence in Sydney back in 2019.
It was this that encouraged him to take an additional step and install a battery in 2022.
Mr. Anderson chuckles as he remembers, "The amusing part is that when I initially contacted our solar installer, she said, 'Actually, you don't require a battery.'"
What I meant was, 'It’s not about requiring a battery; it’s about showing defiance and depriving power companies of revenue.'
'All seemed reasonable'
Similar to an increasing number of shoppers, Mr. Anderson was drawn to purchasing a battery by the attraction of a special offer.
For him, it came from one of Australia's major energy providers, AGL, offering approximately $1,000 towards the initial expenses of setting up a system.
As part of the deal, Mr Anderson agrees to join what’s known as a virtual power plant, or VPP.
As part of a Virtual Power Plant (VPP), businesses that manage—or aggregate—households’ batteries and other green technologies can utilize these devices based on the requirements of the power grid.
Mr. Anderson mentions that during the initial year following his participation in the program and obtaining the battery, he hardly observed any difference.
He mentions that everything was quite serene and laid-back.
It went like this: 'Here’s the situation, we assure you we won’t do those things, we pledge we’ll handle these tasks, we deduct a grand from the battery cost, and lock you into a five-year plan to keep you enrolled for five years.'
The concept behind it was to assist in stabilising the grid during chaotic moments.
It all appeared quite sensible.
In the initial year, I doubt they even laid a hand on the battery.
It all transformed about a year later when Mr Anderson began observing some significant changes.
A shocking surprise
To begin with, he says AGL put him unexpectedly on a complex pricing system called a demand tariff.
With a demand tariff, customers get billed based on their highest half-hourly usage of electricity drawn from the grid over the span of an entire month.
These measures aim to deter individuals from utilizing electricity from the grid during peak hours; however, both consumer advocates and certain regulatory bodies argue that these policies are confusing, unproductive, and unjust.
AGL refuted claims they failed to offer sufficient notice, emphasizing that Mr Anderson had received written correspondence alerting him to the upcoming changes beforehand.
In addition, Mr Anderson claims that AGL also began "depleting" his battery occasionally, which made him purchase electricity from the grid during high-price periods.
Adding to his frustration, he states that these alterations resulted in a double blow—by compelling him to purchase electricity from the grid during high-demand hours, he asserts this increased his expenses due to the demand tariff.
AGL has challenged this assertion.
He mentions that they altered how they utilize the battery.
It started with small sips occasionally but quickly turned into draining it all the way down to its 5 percent reserve level, essentially emptying everything out.
You could trace their actions back to the time when prices in the national electricity market surged dramatically.
Gabrielle Kuiper is an advisor with expertise in implementing and incorporating solar panels along with battery systems.
She states that virtual power plants have substantial potential as the energy transition accelerates, with the possibility of participation from millions of homes and enterprises growing over time.
Plus, she believes initiatives like the commitment made by the federal Labor government to provide subsidies for home battery systems will probably amplify this phenomenon even further.

"Currently, more than one-third of Australian households have installed rooftop solar systems, yet fewer than 10 percent have adopted battery storage solutions," according to Ms Kuiper.
When we amass numerous batteries along with many electric vehicles capable of returning energy to residential areas or the power grid, it will transform into a substantial component of the electrical infrastructure.
In whom to trust?
Ms Kuiper indicates that instances like Mr Anderson's should act as a cautionary tale regarding the risks associated with VPPs that are inadequately designed or overseen.
She states that for these programs to succeed, customers must be capable of trusting them.
Ms Kuiper states, "We've had trust issues with electricity spanning decades."
As far as I understand, major energy retailers are considered less trustworthy by consumers compared to banks.
Indeed, some genuine hurdles exist over there.
Ms Kuiper indicates that regulators must guarantee consumers receive accurate guidance and adequate protection.
She believes there isn’t enough data available to assist the typical homeowner in understanding and maneuvering through the market.
She is concerned that without this occurring, customers might not get to enjoy numerous advantages from their personal investments.
She mentions this as a developing and recent concern.
It's crucial for the Australian Energy Regulator to step up and enhance transparency while providing greater details to consumers.
The concern here is that large aggregators, specifically the major four retail companies, capture a significant portion of the profits generated through household and business energy technologies, especially batteries, within virtual power plants. As such, participants in these VPPs might not receive adequate benefits.
Energy giant steadfast
AGL, being the largest energy retailer in Australia with over 4 million clients, stood by its decisions concerning Mr. Anderson and how it handled the Virtual Power Plant (VPP).
A representative denied allegations that AGL completely drained the batteries of involved households, stating that the firm’s protocol ensures at least 20 percent battery charge is always retained.
The spokesperson similarly dismissed claims that Mr. Anderson's tariff was altered due to his involvement in the VPP program.
She mentioned that the alteration in tariffs was a distinct issue.
The spokesperson admitted that certain clients were switched to demand tariffs in regions where applications were made, which includes large parts of New South Wales.
The spokeswoman highlighted, however, that it was the pole-and-wire businesses—not the retailers—that originally initiated the tariff modifications.
In contrast, retailers simply reflected these changes to customers and consistently made sure they offered proper notifications.
In response to growing opposition against the implementation of demand tariffs, it is believed that AGL has ceased to apply this fee.
Rather than that, the firm has mentioned it aims to keep customers on their current rates like fixed-tariffs and usage-based pricing once their meters are updated.
The spokesperson stated that AGL boasts one of the biggest expanding virtual power plants in Australia.
Customers can choose to participate in the VPP voluntarily, and by joining our program, they will be compensated for permitting us to utilize their battery in this manner.
A participant's battery in a VPP is never completely drained.
Reality versus rhetoric
For Mr Anderson, his personal experience was poor enough to make him decide to exit the VPP scheme.
In the future, he states that he will handle his own energy requirements.
He thinks this is clearly an improper use of the virtual power plant solution.
Their actions are depleting resources meant for other clients, leaving you stranded.
Now, I reckon if you dig into the small print… you won’t find any assurances about that.
However, there’s the manner in which they promote it and the attitude with which they do so, which starkly contrasts their previous behaviour.
