Solar Panels for Commercial Buildings
What is a commercial battery storage system?
A commercial battery storage system is a clean technology designed to store electrical energy for use at a later time. These systems serve as the backbone of a business's energy infrastructure, providing the ability to store electricity when demand is low and dispatch it when demand is high. This ability to control when and how electricity is used provides a significant advantage, allowing businesses to operate more efficiently and sustainably.
Commercial battery storage systems utilize advanced battery technologies, which are installed on a business's premises. The stored energy can be derived from various sources, including the grid during off-peak times or from renewable energy installations such as solar panels or wind turbines. Once stored, this energy can be used in several ways: it can be dispatched during peak demand times to reduce energy costs, used as a backup power source during outages, or even fed back into the grid in certain scenarios.
Commercial battery storage systems are not just about energy independence—they are also about smart energy management. These systems can be programmed to optimize energy use based on various factors, such as energy prices, peak demand times, and the business's specific energy needs. In essence, a commercial battery storage system allows businesses to take control of their energy use, improving efficiency, reducing costs, and supporting sustainability efforts.
How do commercial battery storage systems work?
Commercial battery storage systems work by capturing and storing electrical energy, and then providing that energy when it's needed. This process involves a numberof stages:
Charging: The first step is charging the system. This involves taking electricity from a source—whether it's from the grid or from a renewable energy system like solar panels or wind turbines—and storing it in the system's batteries. The energy is often stored in the form of chemical energy within these batteries, ready to be converted back into electrical energy when needed.
Storing: Once charged, the energy is stored until it's needed. Advanced battery technologies used in these systems can hold a substantial amount of energy for extended periods. This stored energy can be used at any time, providing flexibility in managing energy demands.
Discharging: When energy is required—for instance, during peak demand times, during a power outage, or when renewable sources aren't producing energy—the system discharges, converting the stored chemical energy back into electrical energy and delivering it where it's needed.
Managing: Most commercial energy storage systems also have a management component. This is typically a computer system that manages the flow of energy, deciding when to charge and discharge based on various factors like energy prices, demand patterns, and the overall energy needs of the business.
Demand Charge Management: Businesses often face demand changes based on their highest peak energy usage. With battery storage systems, businesses can draw power from their storage system during periods of peak demand, effectively reducing peak grid energy usage and associated demand charges.
Resilience and Reliability: Commercial battery storage systems can provide backup power during grid outages, ensuring uninterrupted operations. This is crucial for businesses that rely on constant power supply, such as refrigerated facilities, hospitals, and manufacturing facilities.
Support for Renewable Energy: These systems are an ideal complement to renewable energy sources like solar and wind. They can store excess energy produced during peak production times for use when production is low or non-existent, such as at night for solar power.
EV Charging Buffer: As electric vehicle (EV) use increases, so does the demand for charging stations. Commercial battery storage can help manage the load of EV charging stations by storing power during low-demand periods and supplying it during times of high demand, preventing overloads and maintaining a stable power supply.
Reduced Carbon Footprint: By optimizing energy usage and enabling the effective use of renewables, commercial battery storage systems can help businesses reduce their carbon footprint and contribute to sustainability goals.
Grid Services: In some cases, businesses with commercial battery storage systems can participate in demand response programs or provide other grid services, which can generate additional revenue or savings.
