Clean energy, green energy. We have been hearing these words everywhere in our country. Most of the commercial spaces in Australia have already been using solar energy for their business operations. While others are planning to switch to solar energy for their electricity needs. Since there is government support and lucrative rebates, hence, it makes it easier for them. Now, businesses are generating their own power and gaining energy independence. But what about power usage? As we know, this generated power has to be consumed in the same instant. This means the excess energy your system is generating from the sun can’t be used, therefore, it goes to waste. This is why businesses need to integrate the Battery Energy Storage System or BESS solutions into their solar energy system. This efficient storage system can store excess energy and store it later usage.
Hence, your solar energy systems can capture the immense power of midday sun and store it for the evening rush. So, when operations demand their highest output, you can use this stored energy efficiently. From manufacturing plants, retail chains and other commercial spaces, BESS is helping companies to take control of their energy use. Let EcoGreen Australia solar companies melbourne show you how commercial sectors are choosing Battery Energy Storage and managing energy, costs, and making their solar energy more efficient.
What is a Commercial Battery Energy Storage System?
Commercial Battery Energy Storage System, or BESS, is a big, smart battery crafted specifically for a business or commercial space with higher energy needs. It’s much larger and more powerful than a usual battery, and it can easily handle the heavy energy needs of commercial operations. It gives you control over your electricity. It stores power when it’s cheap (or free from your solar panels) and lets you use it when grid power is expensive. This helps you lower your bills and provides you with a more dependable or reliable backup power. Hence, if there is a blackout, your operations won’t face any disruption.
How it works?
You can connect your solar panels with Battery Energy Storage system and use energy when you need it, at the best possible price. These systems are so powerful and capable that they can even power up entire regions. Though alternative chemistries are gaining popularity for deep and long-duration storage needs, however, lithium-ion batteries are the most common that businesses prefer for their commercial needs. They are highly efficient and durable. The commercial BESS systems keep the operational momentum going and reduce reliance on expensive peak electricity. Also, you can even sell stored power back to the grid and earn through the feed-in-tariff.
The Types of Batteries We Use
When integrating battery storage with commercial solar systems, there are three chemical compositions we use. Lithium Iron Phosphate or LFP, Nickel Manganese Cobalt or NMC, Lead-Acid, and Flow Batteries. But the choice of battery chemistry is not just a technical detail; you need to consider a lot of things, such as performance, lifespan, safety, and, of course, the cost. In Australia, businesses use several battery technologies, and each technology comes with distinct advantages. For the majority of commercial solar integrations in Australia, we use Lithium Iron Phosphate or LFP batteries. These batteries have higher efficiency when it comes to performance, safety, and cost.
| Type | Composition | Depth of Discharge | Energy Density | Safety | Best For |
|---|---|---|---|---|---|
| LFP | 6,000-10,000 | 90-100% | Moderate | Excellent | Daily cycling, safety-critical sites |
| NMC | 2,000-4,000 | 80-90% | High | Moderate | Space-constrained, high-power needs |
| Lead-Acid | 500-1,200 | 50% | Low | Moderate | Budget backup, legacy systems |
| Flow | 15,000+ | 100% | Very Low | Excellent | Long-duration, large-scale storage |
How Does it Benefit You?
Every business has dense operational needs, and one of the major aspects is the electricity need for uninterrupted operation. The Battery Energy Storage system breaks the dependency on the grid. Also, it negates various aspects, such as grid instability or power outages. Furthermore, government incentives and rebates are making commercial energy storage more affordable than the instant discounts on solar and battery systems. Hence, lower upfront costs, shorter payback periods, and scalable systems for all kinds of commercial businesses.
- You can cut down on peak electricity charges
Battery Energy Storage systems let you store low-cost off-peak electricity. This means you can use this stored energy during peak usage and cut down high demand charges. Hence, you can save a lot on commercial electricity bills.
- It gives you an uninterruptible power supply
Blackouts or sudden power outages can interrupt your operations. BESS can protect your business operations from sudden power interruptions and blackouts. This reliability and dependability, make BESS highly efficient and must have for all types of commercial businesses.
- Optimum renewable energy integration
When you use solar energy, you must use it at its maximum. By matching energy supply with consumption timing, BESS provides you with deeper use of onsite or grid-supplied renewables without operational disruption.
- You can earn through feed-in-tariffs.
Battery Energy Storage can help you earn money. Since you are storing the excess energy, you can sell it back to the grid. This is called grid services participation, and you earn through feed-in-tariff.
- You gain energy independence.
Enhanced energy autonomy comes with BESS. These systems can reduce dependence on the grid and make your business energy independent. Also, it will help you be free from grid disruptions and you will gain control over energy sourcing.
Let’s Gain Energy Independence!
We, Aussies, are using renewable energy at its best. By integrating Battery Energy Storage Systems with solar panel installations, Australian businesses have become cleaner and greener. The National Electricity Market is reaching record highs, with more than half of our businesses using renewable energy for their electricity needs and reducing dependency on the grid. Moreover, the government programs or rebates are making solar battery storage systems more affordable than ever.
FAQs
A BESS is a large-capacity, smart battery system that can be integrated with solar energy systems. These systems store excess power generated from solar energy systems for later use.
Without storage, excess energy can’t be used outside production hours and may go to waste. That’s why businesses need Battery Energy Storage systems to store excess energy and use it during evening peaks, busy shifts, and even sell it back to the grid.
Businesses can store cheap or surplus solar energy during off-peak hours and use it during times when grid electricity is more expensive. This way, BESS also reduces electricity bills. Australian government incentives and rebates are also making Battery Energy Storage systems more affordable by lowering upfront costs.
Absolutely. BESS provides you with uninterrupted backup during power outages or unstable grid scenarios. Hence, it ensures your operations run without disruption.
Modern BESS solutions are highly scalable and grow with your business. This means companies can add more storage capacity as energy needs increase.
