BATTERY ENERGY STORAGE SYSTEMS (BESS)

Battery Energy Storage Systems (BESS) are large-scale batteries connected to the electric grid that store energy and release it when demand is highest. By optimizing when energy is delivered, BESS help make the grid more efficient, stable, and reliable. These systems charge when electricity is plentiful or inexpensive and discharge when it's most needed—supporting a cleaner, smarter energy future.

Battery Energy Storage Systems (BESS) store energy when demand is low or when excess electricity is being generated—such as during periods of high solar or wind production. When demand spikes or a power plant unexpectedly goes offline, BESS can instantly discharge that stored energy back into the grid. Traditionally, utilities have relied on “peaker” plants—costly, inefficient, fossil-fueled facilities that take time to ramp up to handle these surges.

BESS provide a faster, cleaner, and more cost-effective alternative, helping to stabilize the grid in real time. By responding in seconds rather than minutes or hours, BESS enhance both the reliability and efficiency of our electricity system, while reducing emissions and operational costs.

Battery Energy Storage Systems (BESS) pose minimal environmental risk. The batteries are housed in sealed, durable metal enclosures designed to prevent exposure to outside elements and to contain any potential leaks internally.

Additionally, safety protocols—including site design, containment systems, and coordination with regulatory agencies—are built into every stage of a BESS project to ensure environmental protection and public safety.

BESS facilities use lithium-ion batteries, which are far less environmentally harmful than older technologies like lead-acid batteries commonly found in vehicles. While small amounts heavy metals are contained in BESS, these are tightly contained and managed with strict handling, transport, and disposal protocols to prevent environmental contamination.

At the end of their life, batteries used in BESS are reused, recycled, or properly disposed of off-site, in full compliance with all environmental regulations. As battery recycling technology continues to improve, more materials are being recovered and reused—further reducing the environmental impact of energy storage.

BESS facilities are quiet and community-friendly, generating very little audible noise. The primary sources of sound are the inverters and the HVAC system used to maintain optimal battery temperature, which together produce approximately 40 decibels. With proper siting and design, any noise is typically inaudible beyond background noise at the facility’s property line.

The BESS produces no air emissions from the facility during operation. Unlike conventional power plants, they do not burn fuel or release any pollutants into the air. As a result, BESS helps improve local air quality while supporting a cleaner, more efficient energy grid.

Safety is a top priority in the design and operation of BESS facilities. These systems are built with multiple layers of fire prevention, detection, and suppression technologies. Inside each facility, automated fire suppression equipment is installed to respond instantly in the unlikely event of a fire. In addition, battery manufacturers integrate advanced safety features—such as thermal monitoring, automatic shutdown protocols, and isolation systems—to prevent overheating or thermal runaway.

We also coordinate closely with local first responders to ensure they are fully trained and equipped to respond to BESS facilities just as they would with any commercial or industrial site. As the industry has matured, stronger standards, improved engineering oversight, and better training have significantly reduced fire risk.
