Battery energy storage systems are revolutionizing how businesses store and utilize renewable energy, offering unprecedented control over energy costs and grid independence.
A Battery Energy Storage System (BESS) allows businesses, agricultural operations, and other energy users to store, manage, and strategically use electricity. At its core, BESS functions like a large-scale rechargeable battery, storing electricity when it is available and releasing it when it is needed. This gives businesses greater flexibility in how and when they use electricity, whether the energy comes from the grid, solar, or another source.
BESS is becoming increasingly valuable as businesses face rising electricity costs, demand charges, and growing energy resiliency needs. By giving facilities greater control over when electricity is used, battery storage can support cost management, improve energy flexibility, and complement renewable energy systems. From manufacturing facilities and cold storage operations to farms with seasonal energy demands, BESS provides another tool for taking a more strategic approach to energy management.
How BESS Technology Works to Store and Deliver Power When You Need It Most
A Battery Energy Storage System operates through a simple cycle: charge, store, and discharge. The system charges when electricity is available or less expensive, such as during off-peak hours or when a solar system is producing more energy than a facility immediately needs. The battery holds that energy until it is needed, then discharges it back to the facility during periods of high demand or when electricity costs are higher.
Modern BESS technology can respond quickly to changing energy needs, often in milliseconds. The system monitors energy use and grid conditions to determine when to charge or discharge, providing automated and responsive energy management. This allows businesses to use stored energy strategically without requiring constant manual oversight.
Battery energy storage can provide value across several areas of a business's energy strategy. For manufacturing, industrial, and agricultural operations, BESS can discharge during periods of high electricity use to help reduce peak demand and potentially lower demand charges. For farms, this can be particularly useful during energy-intensive activities such as grain drying and irrigation.
Beyond cost management, BESS can also improve energy resiliency and operational flexibility. Battery systems can provide backup power for critical operations without the fuel, emissions, noise, and maintenance associated with traditional generators. This can be especially valuable for facilities such as cold storage and food processing operations, where power interruptions can result in product loss or costly downtime. Depending on the system and market, BESS may also provide opportunities to participate in energy programs that can further increase its value.
Pairing solar energy with battery storage allows businesses to store excess solar energy and use it when it is needed most. Solar panels typically generate the most electricity during daylight hours, while a facility's energy needs may continue into the evening or occur when solar production is lower. BESS helps bridge this gap by storing excess generation for later use.
This combination can be particularly valuable for farms with evening and overnight energy demands, such as grain drying, irrigation, and livestock operations, as well as commercial and industrial facilities with significant morning or evening loads. When properly designed, battery storage can also support critical operations during grid interruptions. Together, solar and BESS can help businesses make greater use of the energy they generate while improving flexibility and resiliency.
Determining whether battery energy storage makes sense for your operation starts with understanding your energy use and business goals. BESS may be worth considering if your facility has high electricity consumption, significant demand charges, energy-intensive equipment, or a need for greater operational resiliency. An analysis of your energy usage and utility rates can identify opportunities to reduce peak demand, optimize charging and discharging, and determine the appropriate system size. For facilities with existing or planned solar, this analysis can also help determine how storage could enhance the value of the system.
Choosing the right BESS requires consideration of your facility's electrical infrastructure, available space, safety requirements, and existing equipment. Proper system design, installation, monitoring, and maintenance all play an important role in long-term performance. At Harvest Solar, we approach battery energy storage as part of a comprehensive energy strategy, helping Midwest businesses and farms determine whether BESS is a good fit and how it can support their specific energy goals.
