Battery Storage vs Backup Generators
With utility companies becoming more expensive and unpredictable, having a reliable backup power source is more important than ever. Whether you’re a homeowner looking to keep the lights on during a storm or a business needing to ensure uninterrupted operations, choosing the right backup power solution is essential.
The two most popular options are battery storage systems and traditional generators. Which one is better? Below, we’ll explore the differences between the two, ultimately showing why battery storage is the best choice for your peace of mind.
Battery Storage
Battery storage systems prepare you for the next planned or unplanned power outage, huge storm, or managing a utility company’s peak times by storing energy from the grid or renewable sources like solar panels. You lower your electricity bills, and earn money through grid services like net metering. The transition to backup power is instant and seamless, with minimal energy loss.
Generators
Generators, on the other hand, burn fuel to generate electricity. They start up when the power goes out, usually after a brief delay. This process is less efficient, with energy lost during fuel conversion, and requires a continuous fuel supply to operate during outages.
Efficiency
Battery storage systems are efficient and cost-effective. They store energy during off-peak times or when renewable sources like solar panels generate excess power. This stored energy is then used when needed. Battery storage ensures that nearly all the energy captured is utilized, making it a reliable and cleaner choice.
Generators, however, rely on burning fossil fuels to generate electricity, which is inherently less efficient. The combustion process leads to significant energy loss through heat and emissions. Generators operate at lower efficiency rates, meaning much fuel consumed is not converted into usable electricity. This inefficiency, combined with the need for continuous operation during outages, results in higher fuel consumption and greater environmental impact.
Sustainability
As touched on above, battery storage systems are the more sustainable choice. They produce no emissions, reducing a home’s environmental impact. Generators, however, rely on fossil fuels, contributing to pollution.
Upfront Costs
Battery storage systems typically have a higher upfront cost due to the investment in advanced batteries. However, this is balanced by lower long-term costs (see below). And, don’t forget, the Federal IRA incentives will help offset your installation bill. In Colorado, there are further incentives to take advantage of. We can help you navigate all of your savings.
Long-term Costs
Battery storage requires little maintenance and no fuel, reducing ongoing expenses. Generators, while cheaper initially, incur significant costs for fuel, maintenance, and repairs. Also, when you pair your battery with solar, you are reducing your electricity bills. You can even control your usage during a utilities peak demand time by moving to your battery storage to keep from paying peak fees.
Battery Storage is more Durable and Longer Lasting
Battery storage not only lasts 10-15 years with minimal degradation, they can handle thousands of charge and discharge cycles. You will be able to rely on your battery for planned blackouts, unexpected storms and demand management.
Generators typically have a shorter lifespan, averaging 5-10 years. They require frequent maintenance, including oil changes and fuel system checks. Over time, mechanical wear can lead to inefficiencies and breakdowns, making them less durable and dirtier than a modern battery system.
Which is Safer?
Battery storage systems are designed with modern safety features like thermal management and automatic shut-off to prevent accidents. These features make them safer for both residential and commercial use.
Generators, on the other hand, pose several risks, including the potential for fires and carbon monoxide poisoning. Proper ventilation and maintenance are essential, but even with precautions, generators are not the safer option.
Performance Matters When The Power's Out
During power outages, battery storage provide instant backup power. These systems kick in immediately when the grid fails, so there’s no disruption to what matters most such as medical equipment, home security, and refrigeration.
Generators, however, often experience a delay before they start supplying power, leading to disruptions. When you rely on critical items like medical devices, you can not afford to have a delay. Since generators require fuel to operate, they become less reliable if there becomes a fuel shortage or access to fuel is not available.
As you can see, battery storage is the way to go when you’re concerned about keeping your home or business charged during power outages. We have expertise to help you choose the right system for your needs, and we will help you understand the incentives available to you.
