Australia, a country of vast open space and abundant sunlight, has firmly established itself as a global leader in rooftop solar adoption.  

According to recent data, the country has over 3.9 million rooftop systems installed, yielding a combined capacity of approximately 37.8 GW of PV. This remarkable achievement reflects the country’s strong commitment to a sustainable energy future. 

But what happens when the sun goes down or when the grid fails?  

Yes, that’s where home battery storage steps in, and no name resonates more loudly than Tesla Powerwall! 

With the release of the Powerwall 3 and evolving energy landscapes, many Australian homeowners are asking: Is a Tesla Powerwall still a worthwhile investment in 2025?  

If you’re an Australian looking for a home solar battery, Tesla Powerwall is arguably the most popular home battery on the energy market right now.  

So, here’s why Tesla Powerwall could be worth it for your Australian home!

But First, What Is Tesla Powerwall?

Back in 2015, Tesla ventured into the energy storage market with the Tesla Powerwall, a home battery system. This battery system is specially designed to store energy, mitigating the intermittency of renewable energy sources. 

Although Tesla was globally recognized for its electric vehicles, the launch of the storage battery, the Tesla Powerwall, marked another bold leap for the company.  

This home energy storage is a rechargeable lithium-ion battery that can keep your home illuminated 24/7 with reliable power and significantly reduce your electricity bills. 

Powerwall’s smart system can be tailored to your specific energy requirements. This battery can be charged from solar energy, ensuring that power is always available on demand. It essentially serves as a backup power source for nighttime or cloudy days.  

Following their initial release in 2015 in limited quantities, Tesla has continually expanded its energy lineup with larger-scale solutions.  

In 2025, Tesla’s lineup includes three Powerwall models: Powerwall 2, Powerwall+, and Powerwall 3. Each model offers 13.5 kWh of usable energy storage.  

In Australia, Powerwall+ and Powerwall 3 are designed for new solar and storage system installations, which involve integrating solar inverters for higher efficiency. At the same time, Powerwall 2 is often used for retrofitting existing solar systems. 

Now, they also offer different categories, such as the Powerpack, designed for commercial and industrial use, and the Megapack, engineered to support utility-scale grid operations, among others. 

How Does Powerwall Work? Find Out!

In general, the Tesla Powerwall is a rechargeable home battery system that stores energy for later use while providing essential security and financial benefits.  

It works seamlessly with solar panels or the electric grid to manage energy supply and demand in your home.   

It includes energy monitoring, metering, and smart controls, which the owner can customize and control via the Tesla app.  

The system then learns and adapts to your energy consumption slowly over time. It receives over-the-air updates to add new features and improve existing ones.  

How Does Powerwall Work

Here’s a step-by-step guide on how it works: 

Step 1:  Energy Collection 

  • With Solar Panels 

Your solar panels usually generate electricity during the day. From that, some of this energy powers your home, while the excess charges the Powerwall battery.

  • Without Solar 

If you don’t have solar panels, the Powerwall can charge using electricity from the grid when rates are low, for example, at night.

Step 2:  Energy Storage 

  • The Powerwall stores the unused electricity in its lithium-ion battery. 
  • This stored energy is saved for when you need it most, like during peak usage times, at night, or during a power outage.  

Step 3:  Energy Usage 

  • When solar production drops or the grid goes down, the Powerwall automatically kicks in, supplying your home with clean, stored renewable energy.

Step 4. Intelligent Management with the Tesla App 

  • The system learns your energy usage patterns and optimizes when to charge or discharge.
  • You can monitor and control everything through the Tesla app, giving you real-time insight into your energy use, storage levels, and solar generation.

The Australian Energy Rollercoaster: Why Batteries Are More Relevant Than Ever?

This puts the total installed cost of a single Powerwall 3 in the ballpark of $14,600 to $16,000 AUD. 

While this might seem steep, it’s crucial to factor in the various incentives and potential savings.

The Australian Government’s Rebates and Incentives in 2025

Good news for Australian homeowners! 2025 is a sweet spot for solar battery rebates, with a significant federal program coming into play: 

  • Federal Cheaper Home Batteries Program (Starts July 1, 2025) 

The Australian Government has announced an upfront discount of approximately 30% on the cost of installing eligible small-scale battery systems (between 5 kWh and 50 kWh).  

For a 13.5 kWh Tesla Powerwall 3, this could translate to a rebate of around $4,725. The discount is based on usable capacity and will gradually decrease until 2030, making 2025 the optimal time to jump in.  

The discount is applied upfront by accredited installers, making it easy for consumers. 

  • State-Based Incentives 

While the NSW Peak Demand Reduction Scheme (PDRS) battery rebate ends on June 30, 2025, it will be replaced by an expanded Virtual Power Plants (VPP) incentive from July 1, 2025, offering a single upfront payment of up to $1,500.  

Other states like Victoria (interest-free battery loan up to $8,800), ACT ($15,000 interest-free loan), and Western Australia (up to $7,500 rebate and loans) continue to offer their own incentives.  

Altogether, these rebates dramatically lower battery costs, often by 30–50%, making the Powerwall 3 far more accessible.

New Jersey’s Electricity Rate Crisis Is A Perfect Storm for Wind Energy

New Jersey’s Electricity Rate Crisis Is A Perfect Storm for Wind Energy

New Jersey ratepayers received an unwelcome surprise in June 2024 when electricity rates jumped between 17 and 20 percent virtually overnight. But behind the dramatic increase is a much larger story about the challenges facing renewable energy deployment, grid modernization, and the future of power generation across the PJM Interconnection region—one that has significant implications for the wind energy industry.

According to Kyle Mason, Associate Planner at the Regional Plan Association, the rate spike stems from record high prices in PJM’s annual capacity auction, which secures power for peak grid loads. PJM operates the grid for New Jersey and 12 other states, covering over 60 million people. The capacity market’s unprecedented pricing “trickled down to increased electricity rates for New Jersey rate payers,” Mason explained.

Old Grid, New Demands

“We have a very old grid, and we’re trying to update it in real time,” said RPA’s Robert Freudenberg – while bringing more energy onto the system. “It’s like trying to build the plane while you’re flying it.”

Freudenberg, Vice President of the Energy & Environment Program at RPA, described the crisis as a convergence of multiple factors: the grid’s age presents challenges, the interconnection process has slowed dramatically, and demand is skyrocketing.

The interconnection queue process, which once took a few years, now stretches across many years. According to Mason, as of April of last year, over 200 gigawatts of projects sat waiting for study in the interconnection queue, with approximately 98 percent comprising solar, wind (both onshore and offshore), and storage. Even if only half of those projects eventually come online, Mason noted, “it would markedly improve the rate situation.”

Unprecedented Demand Growth

The energy demand situation is compounded by explosive load growth, driven largely by artificial intelligence and data centers. Mason noted that current projections show load growth reaching five percent annually—levels, he said, “we have not seen…since air conditionings were invented.”

These aren’t small facilities. “The industry is seeing massive, massive expansion of data centers,” Mason said. “Not just small data centers that we saw expand during the years leading up to the dot-com bubble, but rather these massive hundred-plus megawatt data centers,” primarily concentrated in Northern Virginia, New Jersey, Pennsylvania, and Ohio.

By 2030, data centers alone could account for 10 to 12 percent of electricity demand on the PJM grid—a staggering figure that underscores the urgency of bringing new generation capacity online quickly.

Offshore Wind “Ideal Solution” for Energy Island

New Jersey, the most densely populated state in the country, uses more energy than it produces. Thanks to that distinction and its geographic constraints, it’s referred to as an “energy island”- where wind represents an ideal solution for large scale generation.

The state had plans for approximately five gigawatts of offshore wind capacity, including the 1,100-megawatt Ocean Wind project, which has since been abandoned. Federal policy shifts have further complicated the landscape, effectively putting offshore wind development on ice across the region.

Freudenberg pointed to the South Fork Wind farm off Long Island as proof of concept.

“If you look at the data from that, [South Fork] is performing very well. It’s reliable,” he said, noting it put a thousand people to work and stabilized rates for customers.

Grid Reliability Challenges

Adding another layer of complexity, PJM recently implemented stricter reliability rules that dramatically reduced the amount of generation qualifying as reliable.

“The buffer dropped from about 16 gigawatts of supposedly reliable energy sources to about 500 megawatts when the reliability requirements were issued,” Weather Guard Lightning Tech CEO and Uptime Podcast host Allen Hall notes in the interview.

“Many fossil fuel plants face reliability concerns during extreme weather events, extreme cold events,” Mason explained. That made the older plants ineligible to enter PJM’s capacity market under the new rules. That caveat simultaneously removes baseload capacity while renewable projects remain stuck in the interconnection queue.

New Jersey's Electricity Rate Crisis Is A Perfect Storm for Wind Energy

Is PJM’s Progress Too Little, Too Late?

PJM has made some progress addressing interconnection challenges. Working with the Federal Energy Regulatory Commission, the grid operator implemented a new cluster study process that prioritizes projects on a “first ready to serve basis” rather than first-come, first-serve. Mason reported they’ve already studied over 40 gigawatts of energy, “and that’s starting to get built,” Mason said.

“But there’s the question of whether that can outpace the rising demand,” he said.

On transmission infrastructure—a critical bottleneck for wind energy—the average timeline to build high voltage transmission lines stretches to 10 years. Mason noted projects face “years and years just to get the materials to build power plants, and then 10 years with permitting costs and supply chain issues and permitting timelines to build the transmission wires.”

Policy Recommendations: States to Lead the Way

Despite federal headwinds, Freudenberg urged states to maintain momentum on offshore wind.

“States need to keep the charge on for offshore wind. They need to keep the fire burning for it,” he said, recommending that states prepare transmission infrastructure and work with developers so projects can move forward quickly when federal policy shifts.

New Jersey has taken some positive steps, recently announcing its Garden State Energy Storage Program that targets over two gigawatts of storage capacity and releasing grid modernization standards for utilities.

Of course, when utilities are required to modernize, rate payers usually foot (most of) the bill. Still, having an available, reliable energy supply is the first order of business.

For wind energy operators and stakeholders, the New Jersey situation illustrates both the critical need for renewable generation and the complex policy, infrastructure, and market challenges that must be navigated to deliver it.

As Freudenberg summarized: “The ingredients here are so good for offshore wind. Everything… the proximity, the wind speeds. All we have to do is build those things and connect them into our grid and we’ve got a lot of power.”

The question is whether policy will allow that to happen before the grid crisis deepens further. We’ll be watching closely!

Chopin — Music that Inspires

Published

on

There’s a story behind the piece below, Chopin’s “Heroic” Polonaise, performed by Vladimir Horowitz, the pianist most people deem to be the world’s top interpreter of Chopin.

Frederic Chopin was born in 1810 near Warsaw, Poland, and was known as a child prodigy as a pianist and composer by the time he was six or seven.

Russia had long ruled Poland, but in the 1820s, Russian rule grew more arbitrary, and secret societies were formed by Polish intellectuals in several cities to plot an insurrection. In November 1830, Polish troops in Warsaw rose in revolt.

Chopin moved to Paris shortly after his 22nd birthday, where he would spend the rest of his life composing, teaching, and concertizing, but his love for his native land remained fierce.

But what could he do? Chopin was a small and sickly person, barely five feet tall, perhaps 90 pounds in weight. He certainly couldn’t be a physical part of an uprising, but he could inspire his native Poles with his compositions.

There are a few good examples of his works along these lines, but the Heroic polonaise stands by itself. When I hear it, a single word comes to fore: bravery.

Enjoy, and don’t be embarrassed if you have goosebumps.

Some of us are looking for a single, simple statement to encapsulate what is going so wrong in America today, and perhaps it relates to what Aristotle says at left here.

Even the MAGA folks think that what they’re doing is “right.”  By this I mean white supremacy, mass deportation of immigrants (with or without due process), the rejection of science, and so forth.
