What is a battery energy storage system?

A BESS is a system of batteries that draws power from the electric grid at times when excess power crowds transmission lines, and then discharges this surplus energy when customers need it most. In addition to other benefits, battery storage allows customers to use renewable energy even when the wind isn’t blowing and the sun isn’t shining. And because of its small footprint, a BESS can create value on land parcels that are otherwise unusable.

Why host a BESS on my land?

A hosting lease agreement can provide landowners with stable revenue for the 20-to-30-year lifespan of a BESS. In addition, when Able Grid leases a site, the project provides annual property tax revenues to your local tax authority. At the end of the project’s life, much of the equipment on site will be recycled and the parcel returned to its original condition.

What does a BESS look like?

A BESS consists of a series of batteries within a small building or modified shipping container that is temperature-regulated by an HVAC system and surrounded by a fence and landscaping per local requirements. The layout of a project can be adapted to a particular parcel. Rectangular and square parcels can most efficiently house rectangular battery racks. And depending on local standards, a taller building may accommodate the BESS on a smaller parcel. The image at the top of this page is an example of how a BESS might look on your property.

How does it work?

Wiring from the batteries connects to multiple power conversion systems that feed into the main power transformer. Once the transformer steps up the power to the high voltage of the transmission system, an overhead power line connects the project to a utility substation. The battery can pull power from or push power to the electric grid based on signals from grid operators.

What about emissions and water use?

No fuel is consumed on site, so every BESS is a zero-emission facility. Although water is not used for operation, some stored water on site may be required as a backup measure within the thermal management system.

Is there a risk of oil leakage?

Transformers installed in the system are designed to conform to local standards on containment of any oil leakage and are regularly monitored for leaks.

Will it be designed and built safely?

Able Grid has team members on several national standards committees, so we are always up to date on the latest standards for battery energy storage systems. Our technical team will ensure the system you host is designed using the most current requirements developed by independent scientists and engineers. Able Grid always acts as a good neighbor, and the BESS will not disturb uses on adjacent properties.
