Energy Storage Solutions

Advanced Battery Storage Systems

Help create a more reliable, affordable and flexible energy grid.

Maximize Land Value Near Substations

🔋 If you own land near a substation, your site may be ideal for battery storage. Battery projects typically yield 3-5x higher revenue per acre than traditional solar developments with smaller footprints.

01

Site Assessment and Site Selection

We identify optimal locations for utility-scale battery storage systems with a particular focus on site selection, grid capacity and demand congestion that maximize the benefits to the grid.

Reliable – Battery storage improves the reliability of the local electrical grid by providing electricity when the grid needs it most.
Affordable – Battery storage helps to reduce electricity prices by supplying energy when demand is at its highest.
Resilient – The grid becomes more flexible when resources are available on demand, making it more resilient to power outages.

Neighbors and Battery Farm Information

Being a Good Battery Farm Neighbor

We understand that your neighbors may have questions or concerns about your new battery farm installation. Here's how our battery energy solutions are designed with neighborhood harmony in mind.

Odorless and Dark

Battery storage systems are completely odorless. The battery cells are hermetically sealed within weatherproof enclosures that prevent any emissions or leakage.

There will be no permanent lighting installed at the battery farm site, ensuring zero light pollution and preserving the natural night environment.

All site and access lighting is temporary and used only during maintenance activities, and is fully shielded to prevent any light spill beyond the operational area.

Improved Electrical Grid

Battery storage systems improve the electrical grid by providing electricity when it’s needed most. They charge when demand is low, and discharge when demand is high, helping to balance the grid and reduce peak pricing.

By positioning battery storage near key substations, costly grid upgrades like new transmission lines can be deferred or avoided altogether.

Having electricity on demand improves grid flexibility during periods of stress like extreme weather events.

Quiet Operation

Battery units are completely silent with no moving parts. The only components that produce sound are the cooling system and the inverters, which convert stored DC electricity into usable AC power.

Modern battery systems operate at noise levels similar to a quiet refrigerator or soft conversation, and are typically inaudible beyond the substation fence line.

Battery systems are installed immediately adjacent to substations and away from densely populated areas to minimize any potential noise impact on neighboring properties.

Appropriately Located

Battery storage systems are located very near or immediately adjacent to utility substations. Their proximity helps to minimize the amount of required electrical infrastructure.

Battery storage systems are kept out of sight by minimizing road frontage and installing vegetative buffers.

The interconnection of projects in key areas of congestion on the electrical grid means the investment goes where the need is greatest.

Frequently Asked Questions

Find answers to common questions about battery energy storage, with links to research and resources that provide in-depth information on key topics.

Where is a good place for a battery storage system? +

Battery storage systems should be located near or immediately adjacent to utility substations in areas of grid congestion. By adding additional, flexible capacity to the electrical grid, we are able to defer or avoid the addition of other forms of generation which are more land intensive.

What are the tax implications for landowners? +

The solar or battery project pays all personal and real property taxes associated with the project. You as the landowner will have fewer taxes to pay than today, while at the same time the community benefits from a higher tax base, helping to provide community services.

What happens to batteries at the end of their useful life? +

Batteries typically reach end of useful life after 10–15 years of operation. At that point, we follow a multi-step process to ensure safe, responsible handling and maximum resource recovery:

  • Assessment & Repurposing: First, cells are evaluated for residual capacity. Modules with remaining useful capacity can be repurposed for lower-demand applications (e.g., backup power or off-grid use).
  • Dismantling & Sorting: Systems are disassembled; components such as busbars, enclosures, and electronics are separated for reuse or recycling.
  • Recycling: Valuable materials (lithium, cobalt, nickel, copper, aluminum) are recovered through mechanical and hydrometallurgical processes at certified facilities.
  • Safe Disposal: Any non-recyclable materials and packaging are disposed of according to federal and state hazardous waste regulations.
  • Reporting & Transparency: Full chain-of-custody documentation is provided, detailing material flows and recovery rates.

This comprehensive approach minimizes environmental impact, supports a circular battery economy, and ensures compliance with all regulatory requirements.

How do battery installations perform during extreme weather events? +

With the increasing frequency of extreme weather events, the resilience of battery energy systems is a key consideration. Modern battery installations are engineered to withstand harsh weather conditions, including high winds, flooding, extreme heat, and cold temperatures.

According to the American Clean Power Association's research on extreme weather performance:

  • Battery systems are housed in weatherproof enclosures rated for extreme conditions
  • Installation designs accommodate wind speeds of 140+ mph (exceeding most hurricane categories)
  • Advanced thermal management systems maintain optimal battery temperatures even in extreme heat or cold
  • Battery installations can be elevated above flood levels in areas prone to flooding
  • Battery systems can provide backup power during grid outages, supporting critical infrastructure

The study also documents real-world performance of battery installations during extreme weather events, including hurricanes in Florida and Texas, showing remarkable resilience even in the most challenging conditions.
