Energy Arbitrage: Buy Low, Sell High & Maximize Your Energy Profits.

Energy arbitrage lets you profit from electricity price fluctuations by charging batteries when prices are low and selling excess power when prices spike. Jousto automates this entire process, ensuring you always buy cheap and sell high

—without lifting a finger.

What Is Energy Arbitrage & How Can You Profit from It?

Energy arbitrage is the process of buying electricity when prices are low (or negative) and selling or using it when prices are high. With wholesale energy providers like Amber Electric and Local Volts, prices can swing from negative to over $19 per kWh, creating huge profit opportunities.

With Jousto, you can:

✔ Charge a battery without solar —buying cheap energy and using it later.

✔Turn off solar & charge from the grid when prices go negative.

✔ Maximise battery storage —exporting or self-consuming when it’s most valuable.

Jousto automates the entire process, so you always buy low and sell high—without lifting a finger.

Dynamic Solar & Grid Switching – If prices go negative enough, Jousto curtails solar output and switches your home to grid power—getting you paid to use electricity.

Sell Excess Energy at Peak Prices – When prices spike, Jousto automatically exports stored energy to the grid at the highest possible rates.

No Manual Work Required – Jousto does everything for you, hassle-free.

Who Benefits from Energy Arbitrage?

Energy arbitrage isn’t just for big energy companies homeowners, businesses, and battery owners can all profit from fluctuating electricity prices. Whether you have solar, a battery, or no solar at all, Jousto ensures you always buy low, sell high, and maximise savings.

From solar homes looking to avoid low feed-in tariffs

to businesses managing high energy costs, energy arbitrage is a game-changer.

With Jousto’s automation, you don’t have to watch the market—your system automatically adjusts in real time to get the best financial outcome.

Homeowners with Solar – Stop losing money on low feed-in tariffs. Charge batteries at negative prices and sell excess power at peak rates.

Battery Owners (With or Without Solar) – Don’t have solar? No problem. Jousto fills your battery when prices are lowest and powers your home when rates rise.

Businesses & High-Energy Users– Reduce operational costs by strategically charging and discharging based on energy market fluctuations—automated 24/7.

The Risks & Challenges of Energy Arbitrage – And How Jousto Solves Them.

Energy arbitrage can be highly profitable, but it’s not without risks.

Market prices change rapidly, and without the right tools, you could end up buying at the wrong time, missing peak sell opportunities, or even paying to export power.

That’s where Jousto comes in. Our automated system removes the guesswork, constantly monitoring the market to charge, discharge, or switch power sources at the optimal moment.

No manual tracking, no complex decisions—just smarter energy use and higher profits, completely hands-free.

Price Volatility Can Be Unpredictable – Real-time monitoring ensures your battery charges when prices are lowest and sells when prices spike—fully automated.

Manually Managing Arbitrage Is Difficult – Jousto eliminates guesswork by automatically adjusting your energy strategy 24/7, so you never miss an opportunity.

Exporting Solar at the Wrong Time Can Cost You – If prices go negative, Jousto curtails solar and switches to grid power—so you get paid to use electricity instead of paying to export.

Not Everyone Has Solar – Can I Still Benefit? – Yes! Even without solar, Jousto helps battery-only setups profit from wholesale energy price swings.

Frequently Asked Questions

Question 1: What is energy arbitrage, and how does it work?

Energy arbitrage is the process of buying electricity when prices are low or negative and selling or using it when prices are high. Jousto automates this, so you always maximise savings and profits.

Question 2: Do I need solar to take advantage of energy arbitrage?

No! Jousto works with battery-only setups. You can charge your battery from the grid at low prices and use or sell the energy when rates rise.

Question 3: How does Jousto decide when to charge and discharge my battery?

Jousto monitors real-time electricity prices and automatically charges your battery when prices are lowest. When prices peak, it discharges or exports energy for the best return.

Question 4: What happens when electricity prices go negative?

If prices drop low enough, Jousto curtails solar and switches your home to grid power, meaning you get paid to use electricity instead of paying to export excess solar.

Question 5: Can I still export solar when prices are high?

Yes! Jousto detects price spikes and ensures you export stored energy at the highest possible rates, maximising your profits.

Question 6: What if the market shifts while I’m away?

Jousto runs 24/7, adjusting automatically based on live pricing—so you never miss an opportunity to save or profit.

Question 7: Will Jousto work with my energy provider?

Jousto is designed to work best with Amber Electric, Local Volts, and other wholesale energy providers, but can also optimise energy use for homes and businesses on standard plans.
