Allen Hall: I’m Allen Hall, president of Weather Guard Lightning Tech. And I’m here with the founder and CEO of Intel Store, 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 want market intelligence that generates revenue, then book a demonstration of IntelStor at IntelStor.com.

Arclight Capital Partners has launched SkyVest Renewables, a new initiative focused on operating and optimizing renewable energy assets. With an initial 500 million capital commitment, SkyVest has already acquired a 160 megawatt farm facility. And Texas, the company aims to target operating utility grade wind and solar assets in North America, implementing best practices to generate near term cashflow and mitigate risks.

Phil, there should be a lot more companies entering this marketplace. It can be a big revenue generator.

Philip Totaro: Well, and this follows on the trend that we’ve been talking about for months, which is, I mean, for those that don’t know, ArcLight already has ArcLight Capital Partners, the, the kind of umbrella and parent of, of this infrastructure company.

They already have some ownership of assets wind and solar throughout the U. S. It’s a smaller portfolio, but they were kind of dipping their toe in the water, and now You know, standing up a new project development and asset management company with SkyVest is is fantastic to see. And I think, with the capital commitment they’ve got with 500 million, that’s a good place to start.

But in reality, there’s probably a lot more coming and you should expect that that Arclight’s going to be doing a lot to help them raise funds. and deploy that capital following on that, that trend of infrastructure companies doing, doing that throughout the globe.

Joel Saxum: I know I talk about oil and gas and lessons learned and like things that can be taken from that sector, but in the oil and gas world, you’ll see that people buy and sell oil fields left and right.

There’ll be group, large asset grabs or, or even a single well or something like this, but a lot of times it’s a field. And we’re starting to see that more and more in the wind industry, because what people will do in the oil industry is buy that field, optimize it, they’ll do a little CO2 injection, or they’ll do work over, bring in work over rigs, clean up the wells, get them working better, and then they’ll dump it, sell it to someone else that wants to operate it.

So we’re seeing some more capital come into the space now where they’re buying up wind farms, our ArcLight Capital, bought that 160 megawatt wind farm in Texas. And they’ll optimize it, right? They’ll put a little bit of money in it. They’ll put some, do some best practices stuff and they’ll get that thing running better.

Whether it’s through just best practices or whether it’s through new sensor technologies or new LEP upgrades or lightning protection upgrades or whatever they may be, get that thing up and moving and then possibly sell it in the future for a profit. And that is starting to happen more and more and more in the wind industry at a global scale.

Allen Hall: Spanish oil company Repsol is in talks to acquire the remaining 60 percent stake in U. S. renewable energy company, Hecate energy Repsol already owns 40 percent of Hecate energy group, which develops renewable projects in the U S and this move follows Repsol’s recent acquisition of ConnectGen for almost 800 million, further expanding its presence in the U S renewable energy market.

Phil, why is a large Spanish oil production company moving to renewable projects in the U. S. right now?

Philip Totaro: They actually are seeing potentially better returns for those that don’t know this company, Hecate Energy, They have already deployed some battery storage projects in the U. S. They have a significant development pipeline, and most recently, they just proposed to develop a, an offshore wind farm.

in some of the project sites that were pulled from a BOEM auction in the Gulf of Mexico, specifically for hydrogen generation. So they’re, they’ve got quite an interesting pipeline and it’s a play that Repsol obviously wants to be not just a Spanish oil company, They want to be a global energy company.

And this is a way in which they can kind of get their foot in a market where they see a lot more opportunity that potentially what they see in investing in renewables in Spain.

Joel Saxum: Yeah. To partner on with what Phil’s saying there, Repsol, of course, large oil major running operations all around the world, offshore, onshore, all the above.

But in the, when you’re talking in the renewable sector, specifically in wind in Spain, there’s a lot of aged assets. And where they’re hooked into the grid there and the availability of good wind sites, a lot of them are, you’re 15, 20, 25 years old. You’re starting to get to lifetime extension projects.

Whereas when you come to the United States. Of course, the geography is larger. There’s a lot more space for more wind projects. And it is an, it’s a newer market, right? So the assets are younger if you’re trying to buy into other assets and those kinds of things. So, you can see some oil majors starting to pull out of wind or make different moves around it like BP or Shell.

But Repsol diving further in.

Allen Hall: U. S. based Invenergy has partnered with Brazilian investment fund Petria Investments to acquire a portfolio of wind power complexes in Brazil. The 600 megawatt portfolio purchased from Contour Global and Electrobras consists of four projects, all of them located in the northern states of Brazil.

Invenergy will own 10 percent of the portfolio and provide operation and maintenance services, marking its first ownership of installed wind capacity in the country. Now, Phil, Invenergy’s been involved in a number of projects in the United States for a long time, and they do O& M on those projects in the U. S. Now they’re moving into Brazil, what is the incentive to, to move to Brazil to acquire some part of that growing marketplace?

Philip Totaro: Well, this is a really interesting play because this, the, the company they’re partnering with Petria Investments or Petria Investimentos, technically. They are kind of a Brazilian version of an infrastructure fund, if you will, where they are starting to gobble up some of the legacy operational wind and, and even a little bit of, of solar assets in the country.

But specifically bringing in somebody with experience to operate and maintain which I think is interesting that they wouldn’t have worked or partnered with any of the companies down in Brazil. But Invenergy does have an investment strategy that they wanted to kind of. Start getting their, their tentacles out and, and, into different markets.

And Vennergy’s talked about diving into projects in Spain, they’re developing projects in Japan and elsewhere in the world. And so this gives them an opportunity to get a foothold in the Brazilian market. So it’s, it’s a very, very interesting,

Joel Saxum: One of the things Invenergy does in the States, as Allen was talking about earlier, is they will go and build a prod, they’ll, they’ll go through the whole fermenting pipeline, get everything ready, build a project, and they’ll build it with the, basically a selling agreement already in place, right?

They’ll build it and then they’ll sell it to an operator. Immediately once it starts commissioning is complete, then they’ll stay on and they’ll sign an agreement to be the, basically the FSA holder and run the wind farm for them. So I think you could see that possibly that strategy rolling over into Brazil.

So once they’ve established a foothold in Brazil with all these projects, understanding how to operate there, understanding how to do the O& M on these, because of logistically and spare parts and all these different things you have to figure out, I could foresee Invenergy starting to actually do the same thing down there is develop, sell, and continue to run.

But that’s going to be, of course, in the future.

Allen Hall: Spanish renewables company Acciona Energia is considering a major asset rotation strategy amid challenging financial results. The company has identified around six gigawatts of its global capacity for potential sale, representing nearly half of its total installed and consolidated capacity.

Actiona Energia’s first half profits for 2024 have crashed by 84 percent year on year to 65 million euros, primarily due to extraordinary conditions in the Spanish market. Phil, Actiona Energia selling half their assets has got to be a little bit of a warning sign, right?

Philip Totaro: Yes, especially when you consider what Joel just mentioned in regards to, in the Spanish market, you’ve got kind of, a concentration of very experienced companies, but they’re now managing a much older kind of asset portfolio there that is kind of ripe for repowering.

So this could actually be a good thing for them to be able to sell off a portfolio and potentially still have some kind of. Agreement where, you know, because of their ownership stake in, in Nordex potentially get some Nordex turbines in on these potential repowering projects but also gives them, a substantial amount of cash for, for six gigawatts worth of projects that they can also redeploy.

And that’s why they call it kind of this asset rotation. So for those that aren’t familiar, that’s. Asset rotation usually means they’re, selling off an asset that they already own, taking whatever cash they have, and just following the same project development pattern. Again, up to the point where, they can sell off a mature asset to another another owner, potentially a financially focused owner.

Joel Saxum: Something for the listeners to understand here as well as when we say ACCIONA ENERGIA, there’s a lot of ACCIONA group companies. So you ENERGIA, you have ACCIONA ENERGY, which is different. You actually have just ACCIONA. So if you’re thinking, Oh man, this must be affecting these people. It might not be. In the United States, I know they’re completely kind of separate from the Spanish entity and they operate with different principles as well.

So, just something to think about when we talk about this, but that what we’re talking about here with this asset rotation thing, absolutely. A lot of these assets coming to end a life in Spain and something new being needed, needing to be done with them. So there could be some opportunities here for some OEMs to slide in with some big repower projects and sell some turbines.

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.
