Frequently Asked Questions

What does an energy storage project look like?

A BESS facility typically consists of large, modular units that resemble shipping containers. The project site is enclosed by fencing and equipped with security measures like surveillance cameras and lighting to ensure safety. Additionally, robust landscape screening is often employed to minimize visibility and beautify the surrounding area.

What are the components of an energy storage system?

Each energy storage system consists of batteries to store energy, inverters to convert energy between AC and DC, transformers to adjust voltage levels, and control systems to manage operations and ensure safety. These components are enclosed in weather-proof metal containers on concrete or steel foundations, working together as a unified system.

Does an energy storage project change the day-to-day for nearby residents, once installed?

During operations, BESS facilities generate very little traffic, often resulting in fewer daily trips than a single-family home. These facilities are typically located in suburban and rural areas, with setback distances customized to meet specific site requirements.

​

Compared to other energy sources, BESS facilities are ideal neighbors. They offer communities safe, clean, efficient, and affordable energy solutions while maintaining a low profile. These systems produce minimal noise and have a negligible visual impact, occupying a much smaller footprint than other power generation methods.

What are the expected benefits of energy storage projects?

BESS projects help stabilize the power grid, reducing the risk of outages and ensuring a reliable energy supply. They also provide significant economic benefits by generating tax revenue that supports community investments and by creating local construction jobs that boost employment.

How safe are energy storage systems?

Modern BESS facilities prioritize safety. They adhere to all national and local codes and standards, including NFPA 855 and UL 9540, ensuring that installations comply with stringent building, fire, and zoning regulations.

​

Each project is equipped with an emergency response plan, developed in collaboration with local fire officials and independent safety experts. This plan includes comprehensive measures to prevent fires, manage any that occur, protect lives and property, and swiftly address any issues. Additionally, these systems are designed with redundant, fail-safe mechanical components and are monitored around the clock by a remote operations center, ensuring continuous oversight and rapid response.

​

Fire-related incidents at BESS facilities are exceedingly rare. There has never been an incident at a battery energy storage facility that has spread beyond the secure confines of the site. Historical air and water quality monitoring and testing during and after any fires have consistently shown no risk to public health, neighboring properties, or the surrounding community.

How do modern energy storage systems enhance safety and minimize risks?

Modern battery systems are designed to handle even the rarest incidents, such fire, in a controlled manner to prioritize public health and safety. They achieve this by:

Containing Thermal Events

Battery enclosures undergo rigorous testing (e.g., UL 9540A fire tests) and include cooling and gas detection systems to stop fires from spreading.

Stable Battery Chemistry

Newer battery chemistries, such as Lithium Iron Phosphate (LFP), offer enhanced safety features. They have higher thermal thresholds, which protect against overheating and less reactive chemistry compared to older types like Nickel Manganese Cobalt (NMC), both of which significantly reduces the risk of catching fire, even under harsh conditions.

​

Preventing Pressure Build-Up

Special venting systems safely release gases to prevent dangerous pressure accumulation.

​

24/7 Monitoring & Emergency Coordination

Continuous remote monitoring detects early warning signs, such as heat build-up or gas release, enabling operators to intervene promptly. Local fire departments are also trained in emergency response procedures specific to these systems.

What makes Lithium Iron Phosphate (LFP) a preferred battery chemistry?

Lithium Iron Phosphate (LFP) is a type of lithium-ion battery renowned for its superior safety and reliability. Its chemical composition offers greater stability, significantly reducing the likelihood of overheating and minimizing the risk of hazardous reactions. This robust chemistry also extends the battery's lifespan, making LFP a favored and secure option for energy storage applications.
