Allen Hall: I’m Allen Hall, president of Weather Guard Lightning Tech, and I’m here with the founder and CEO of IntelStor, Phil Totaro, and the chief commercial officer of Weather Guard, Joel Saxum. And this is your News Flash. News Flash is brought to you by our friends at IntelStor. If you need actionable information about renewable projects or technologies, check out IntelStor at intelstor.com.

Masdar has signed an agreement to acquire a 50 percent stake in Terra-Gen power holdings from Energy Capital Partners, who will exit its position. Terra-Gen operates approximately 2. 4 gigawatts of wind and solar and 5. 1 gigawatts of energy storage facilities across 32 countries. U. S. sites, mainly in California and Texas, the transaction is expected to close by the end of 2024, while Igneo infrastructure partners will retain its existing 50 percent stake in the company.

So Phil, this is crazy because Mazdar is making big plays in Europe and now the United States. This is an impressive investment.

Philip Totaro: Yeah. And we’ve talked in recent episodes about the fact that Masdar has been making moves back at COP 28, they had publicly announced they were going to spend something like a hundred billion dollars in the next, five or 10 years or something on projects.

And I think it was like 42 different countries. This one’s interesting because of the energy storage play. Energy storage not only has huge growth prospects in the United States, but a company that is as financially focused as Mazdar is. They want to get in on energy storage projects because it gives them the opportunity to do hedging and energy trading.

This is exploding globally. And certainly, if you’re in ERCOT and you’ve got energy storage, you are making bank right now. And California as well. There’s all kinds of markets where, you know, especially if you can time shift power delivery away from negative pricing, which, again, you see sometimes in ERCOT or in CAISO.

This is this is a big opportunity for them. So I like this deal.

Allen Hall: New article from Reuters discussing the valuation of RWE, and if you’ve been following RWE lately, it has dropped 25 percent this year, its stock price has as it tries to transition to more renewable power generation. CEO Markus Krebber faces three main challenges, according to the article, depressed electricity prices due to low gas prices, falling green, Valuations due to rising interest rates and the company’s legacy assets in coal.

And if you, and Joel if, We, I’ve been watching RWE the last several weeks, even though they’re making massive investments in renewable energy, they don’t seem to be getting any credit for it from the stock market.

Joel Saxum: Yeah, it’s interesting because we talk about RWE doing big things all the time, right?

They’re always making some moves. I’m over here, Bilbao, they had a big sign on their side of their booth, 65 gigawatts of clean generation by 2030 is a goal. That’s massive, right? That’s, those are huge numbers, 65 gigawatts. So to me, when you actually, you brought this up and said, yeah, actually RWE stock price is not doing that well.

That was very surprising to me. I don’t see why they’re not getting the love from the markets, to be honest with you. And so if you are looking at some of these commodity prices just depressing that overall market, then I wouldn’t think you would see RW stock falling. Without all of the other operators doing the exact same thing.

Philip Totaro: Yeah. Although their exposure to coal is still obviously problematic and that is probably the biggest drain at the moment. I think the reason that they also don’t get as much credit for renewables projects is because of the. Limited amount of profitability that we’ve seen even for independent power producers in the market.

We’ve seen prices come back up in the past two, three years. Equipment prices power generation and equipment prices wind turbines, solar panels, et cetera. And so as a result you’re seeing thinner margins. From the independent power producers, more of that available margin, assuming that electricity prices that are charged to end consumers aren’t rising all that much.

You’re seeing, more margin being taken away from the independent power producers and being given to some of the OEM companies.

Joel Saxum: The big numbers here to look at is some of the things they’re stating in this Article is a company reducing its CO2 emissions by 27 percent in fiscal year 2023 and increasing its overall renewable electricity production by 27%.

So they are, while they do have the legacy coal issues, they are moving strongly in the direction of a more renewable portfolio.

Allen Hall: Global Wind Service has announced a three year agreement with RWE to support the company’s new offshore efforts in the UK in German waters. As part of this agreement, RWE is changing its strategy from a site by site servicing model to a fleet wide servicing model.

Now, Phil, you start to see this more and more in Europe and the United States is transitioning this way when an operator hires a company to do maintenance, it is becoming more of an area or a fleet wide contracts than the one off farm by farm approach.

Philip Totaro: Yeah, absolutely, and the fact that it’s being done more frequently with independent service providers is also noteworthy because normally, especially in Europe, an OEM gets a long term service contract even on, on offshore, but RWE’s got some of the most experienced people in terms of services and operations they know how to, run their project sites.

They do want somebody like global wind service though, to be able to come in and handle things at scale. And so that’s clearly what was driving that that deal.

Joel Saxum: It’s a win, right? So right now we know it’s hard to get good technicians. So this gives global wind service, the ability to get technicians.

No, they have backlog for them. No, they have work coming up. If they’re not working specifically on this one wind farm as a capital improvement project, whatever it may be. They’ve got work on all these other wind farms going on. So from a manning perspective, it makes absolute sense for RWE and for global wind service.

The other side of it too is vessel use, right? So if you can optimize one thing out there offshore, it’s the time that you spend in the vessel and what it’s used for. So if you spend, if you’re just going farm to shore, one, one wind farm to shore, one wind farm to shore, that’s not an efficient use of the time and money with vessel.

Now you’re bouncing around from wind farm to wind farm, staying out there on SOVs. So you’re a little bit more efficient there as well. And not only are you building that core group of technicians and having them out there and available, but you’re doing it in a more efficient way.

Allen Hall: Maersk Supply Service has partnered with Edison Chouest Offshore to accelerate the installation of offshore wind farms in the U. S. The partnership involves the construction of a purpose built wind farm feeder spread, including two tugs and two barges, to be delivered in 2026. The new feeder spread will transport wind turbine components or foundations to the installation site, potentially increasing installation efficiency by almost 30 percent.

The partnership aims to increase logistical access to more U. S. ports and reduce installation time for the wind farms. Joel, Edison Chouest obviously a big player in the United States and Maersk, a world player in shipping. This seems like a match made in heaven.

Joel Saxum: Yeah, Edison Chouest has a ton of experience.

The Gulf of Mexico, all oil and gas things, Edison Chouest vessels are out there all the time. They’re beautiful. They’re beautiful. Blue and white. They’re always out working. So you would expect, I actually expected to be honest with the America to enter this market earlier. As we saw as VAC to come in, partner up with Crowley, like that was a good tie up as well.

So I thought Maersk would jump in earlier, but the Edison Chouest is the perfect group for them. Edison Chouest as well. Right now they’re actually building a brand new SOV. I believe for Orsted at this time in their, one of their Louisiana shipyards as well. So they’re doing quite a lot.

Philip Totaro: The good news about this, is that it’s providing the U. S. more Jones Act compliant vessels, which obviously we need in order to accelerate the market. The challenge is that. With the pace that the government state or federal wants to get projects going now we’re still not going to have enough vessels to be able to handle the capacity that we’re going to need.

So again, this is a great step in the right direction. But we need to move a lot faster on, U. S. domesticated vessels if we really want to fully capitalize on the U. S. offshore wind market.

ACORE Statement on Treasury’s Safe Harbor Guidance

Statement from American Council on Renewable Energy (ACORE) President and CEO Ray Long on Treasury’s Safe Harbor Guidance:

“The American Council on Renewable Energy (ACORE) is deeply concerned that today’s Treasury guidance on the long-standing ‘beginning of construction’ safe harbor significantly undermines its proven effectiveness, is inconsistent with the law, and creates unnecessary uncertainty for renewable energy development in the United States.

“For over a decade, the safe harbor provisions have served as clear, accountable rules of the road – helping to reduce compliance burdens, foster private investment, and ensure taxpayer protections. These guardrails have been integral to delivering affordable, reliable American clean energy while maintaining transparency and adherence to the rule of law. This was recognized in the One Big Beautiful Act, which codified the safe harbor rules, now changed by this action. 

“We need to build more power generation now, and that includes renewable energy. The U.S. will need roughly 118 gigawatts (the equivalent of 12 New York Cities) of new power generation in the next four years to prevent price spikes and potential shortages. Only a limited set of technologies – solar, wind, batteries, and some natural gas – can be built at that scale in that timeframe.”

Should I Get a Solar Battery Storage System?

Published

on

Frequent power outages, unreliable grid connection, sky-high electricity bills, and to top it off, your solar panels are exporting excess energy back to the grid, for a very low feed-in-tariff. 

Do all these scenarios sound familiar? Your answer might be yes! 

These challenges have become increasingly common across Australia, encouraging more and more homeowners to consider solar battery storage systems. 

Why? Because they want to take control of their energy, store surplus solar power, and reduce reliance on the grid.  

But then again, people often get perplexed, and their biggest question remains: Should I get a Solar Battery Storage System in Australia? 

Well, the answer can be yes in many cases, such as a battery can offer energy independence, ensure better bill savings, and provide peace of mind during unexpected power outages, but it’s not a one-size-fits-all solution.  

There are circumstances where a battery may not be necessary or even cost-effective. 

In this guide, we’ll break down when it makes sense and all the pros and cons you need to know before making the investment.

Why You Need Battery Storage Now?

According to data, Australia has surpassed 3.9 million rooftop solar installations, generating more than 37 GW of PV capacity, which is about 20% of electricity in the National Electricity Market in 2024 and early 2025.  

Undoubtedly, the country’s strong renewable energy targets, sustainability goals, and the clean‑energy revolution have brought solar power affordability, but the next step in self‑reliance is battery storage. 

Data from The Guardian says that 1 in 5 new solar installs in 2025 now includes a home battery, versus 1 in 20 just a few years ago, representing a significant leap in adoption.  

Moreover, the recent launch of the Cheaper Home Batteries program has driven this uptake even further, with over 11,500 battery units installed in just the first three weeks from July 1, and around 1,000 installations per day. 

Overall, the Australian energy market is evolving rapidly. Average household battery size has climbed to about 17 kWh from 10–12 kWh previously.  

Hence, the experts are assuming that 10 GW of new battery capacity will be added over the next five years, competing with Australia’s current coal‑fired capacity.

What Am I Missing Out on Without Solar Batteries?

Honestly? You’re missing out on the best part of going solar. 

Renewable sources of energy like solar, hydro, and wind make us feel empowered. For example, solar batteries lower your electricity bills, minimize grid dependency, and also help to reduce your carbon footprint 

But here’s the catch! Without battery storage, you’re only halfway there! 

The true magic of solar power isn’t just in producing clean energy; it’s storing and using it efficiently.  

A solar battery lets you store excess energy and use it when the sun goes down or the grid goes out. It’s the key to real energy independence. Therefore, ultimately, getting a battery is what makes your solar system truly yours.

Why You Need Battery Storage Now

Here’s a list of what you’re missing out on without a solar battery: 

  1. Energy Independence 
  2. Batteries help you to stay powered even during blackouts or grid failures. With energy storage, you don’t have to think of fuel price volatility and supply-demand disruption in the  Australian energy market. 

  3. Maximized Savings  
  4. Adding a solar battery to your solar PV system allows you to use your own stored energy at night instead of repurchasing it at high rates. It also reduces grid pressure during peak hours, restoring grid stability. 

  5. Better Return on Investment ROI 
  6. Tired of Australian low feed-in-tariff rates 

    Make full use of your solar system by storing excess power at a low price rather than exporting it. Solar panel and battery systems can be a powerful duo for Australian households.  

  7. Lower Carbon Footprint 
  8. Despite the steady growth in solar, wind, and hydro, fossil fuels still dominate the grid. Fossil fuels supplied approximately 64% of Australia’s total electricity generation, while coal alone accounted for around 45%. 

    These stats highlight why solar battery storage is so valuable. By storing surplus solar energy, homeowners can reduce their reliance on a grid that still runs on coal and gas.  

  9. Peace of Mind 
  10. Enjoy 24/7 uninterrupted power, no matter what’s happening outside.  

    Besides powering urban homes and businesses, batteries also provide reliable power backup for off-grid living at night when your solar panel can’t produce, ensuring peace of mind. 

What Size Solar Battery Do I Need?

While choosing the battery size, it isn’t just about picking the biggest one you can afford; it’s about matching your household’s energy consumption pattern. There is no one-size battery that will make financial or functional sense for everyone. 

Nevertheless, if you have an average family of four with no exceptional power demands, you may get by with a 10kWh to 12kWh battery bank as a ready-to-roll backup system.  

Well, this is just an estimation, as we have no idea of your power needs, because selecting a battery is highly subjective to the household in question. 

With that being said, you can get a good idea of how much power you use on average by analyzing your electric bill copy. Also, keeping track of which appliances you use the most and which ones require the most power will help you.  

So, to figure out the ideal battery size for your home, you need to consider three most important things: 

  1. Your Daily Energy Usage

Check your electricity bill for your average daily consumption (in kWh). Most Australian homes use between 15 to 25 kWh per day. 

  1. Your Solar System Output

How much excess solar energy are you generating during the day? That’s the power you’ll store to use later rather than exporting. 

  1. Your Nighttime Power Usage

A battery is most useful at night or during grid outages. So, estimate how much power you typically use after sunset. However, by using a battery, you can also get the freedom of living off the grid. 

Sizing Up: The Ideal Home Battery for Aussies! 

  • For small households and light usage, a 5 kWh battery will be suitable. 
  • For average Australian households, adding a 10 kWh battery would be enough. 
  • Large homes and high-energy users will need a 13 to 15 kWh system. 
  • For full independence, off-grid living, or blackout protection, you may require a larger battery size of 20+ kWh.

How Much Do Solar Batteries Cost?

How Much Do Solar Batteries Cost

Previously, you would have to pay between $3000 and $3600 for the battery alone, plus the cost of installation, for every kWh of solar battery storage.  

However, you can currently expect to pay between $1200 and $1400 for each kWh of solar battery storage. That is a price reduction of approximately 52%, and things will only get better from here. 

Does that imply solar batteries are cheap now? Not really, but the cost is well justified by the pros of having a battery storage system. 

Also, while paying for solar batteries, you have to consider many other factors like the type of battery, your solar panel system configurations and compatibility, brand, and installation partner.  

These will significantly influence the price range of battery storage. 

Is a Solar Battery Worth It | Pros and Cons at a Glance

It’s okay to feel a little overwhelmed while deciding to invest your hard-earned money in a battery.  

So, here we’ve listed the pros and cons of having a solar battery to help you in the decision-making process. 

Benefits of Solar Battery Storage 

  • Solar batteries help you become self-sustaining. 
  • You don’t have to care about power outages anymore 
  • In the event of any natural disaster, you will still have a power source 
  • Battery prices are dropping significantly as we speak 
  • During peak hours, grid electricity prices increase due to high demand; you can avoid paying a high price and use your battery. It’s essentially free energy, as solar generates energy from the sun. 
  • Reduced carbon footprint as the battery stores energy from a renewable source. 

Advantages of battery for the grid and national energy system: 

  • Batteries support Virtual Power Plants (VPPs). In 2025, consumers get financial bonuses (AUD 250‑400) for joining, plus grid benefits via distributed dispatchable power.  
  • Grid‑scale batteries like Victoria Big Battery or Hornsdale Power Reserve are increasing system resilience by storing large amounts of renewable energy and reducing blackout risk. 

Drawbacks of Solar Battery Storage 

  • One of the biggest barriers is that solar batteries have a high upfront cost, which makes installation harder for residents. 
  • Home batteries require physical space, proper ventilation, and can’t always be placed just anywhere, especially in smaller homes or apartments. 
  • Most batteries, like lithium-ion batteries, last 5 to 15 years, meaning they may need replacement during your solar system’s lifetime. 
  • While many systems are low-maintenance, some may require software updates, monitoring, or even professional servicing over time. 
  • Battery production involves mining and processing materials like lithium or lead, which raise environmental and ethical concerns.   

Should You Buy a Solar Battery?: Here’s the Final Call!

You should consider buying a solar battery if several key factors align with your situation.  

First, it’s a strong financial move if you live in a state where federal and state incentives can significantly reduce the upfront cost. This can make the investment far more affordable.  

A solar battery can be especially worthwhile if you value having backup power during outages, lowering your electricity bills, and gaining a measure of energy independence from the grid.  

Additionally, you should be comfortable with taking a few extra steps to get the most value out of your system, such as joining a virtual power plant (VPP), which allows your battery to participate in grid services in exchange for modest returns.  

Finally, it’s worth noting that rebates decline annually, and early adopters get the most value.  

Takeaway Thoughts

Installing a solar battery in Australia in mid‑2025 offers substantial financial, environmental, and energy‑security benefits, especially if you qualify for multiple subsidies and have good solar capacity.  

With rebates shrinking after 2025 and demand surging, early movers stand to benefit most. 

By helping balance the grid and reduce dependence on fossil fuels, home battery adoption contributes significantly to Australia’s national goals of 82% renewable energy by 2030 

It’s not just about savings; it’s about being part of a smarter, cleaner, more resilient electricity future for Australia.

I just spoke with a guy in the wine industry, and I asked him how, if at all, climate change is affecting what we does.

From his perspective, it’s the horrific wildfires whose smoke imbues (or “taints”) the grapes with an unpleasant flavor that needs to be modified, normally by creative methods of blending.
