BESS Site Selection Criteria: The Screen, and the Few Owners It Leaves

Your GIS analyst draws a circle around a substation that still has room on it. Inside the circle sit a few hundred parcels. By Friday, after the layers go on, maybe eight are left.

That's what BESS site selection criteria do. A developer screens for a substation with room to charge and to export. Then for enough flat, dry ground to hold the battery pad and its fire setbacks. Then a road a fire truck can use, zoning that allows storage with no moratorium in force, and neighbors who are far enough away or signed up. Each layer removes parcels. What survives is a short list near one point on the grid.

The software vendors who rank for this search stop there. The work doesn't. The next step is getting the owners of those eight parcels to talk to you, and no filter does that part.

The criteria, in the order they cut

A substation with room to charge and to export

Unlike a solar farm, a battery pulls power off the grid as well as pushing it on. PVcase's checklist puts it plainly. The developer needs to know "how much power can be withdrawn to charge, and how much power can be injected." A substation with export room but no charging room can still kill a battery site.

Distance comes next. Glint Solar says most standalone BESS projects sit within 500 to 1,000 meters of a viable substation, because longer runs add trenching cost and permitting work. Landowners read a shorter version. One landowner site tells them a storage project "must be within half a mile of a substation."

Owners near a substation may have read that line too. For how distance plays out on the solar side, see how far a solar farm can sit from a substation.

Enough acres, then the land around them

Storage needs very little ground for the equipment itself. Indiana's Office of Energy Development puts utility-scale BESS at roughly 0.03 to 0.1 acres per megawatt. A 100 MW project works out to something like 3 to 10 acres of pad.

The parcel has to hold more than the pad. Engineers at Westwood list what comes first in a layout: planted screening and setback buffers, drainage, interconnection equipment, and access roads for semi trailers and cranes. Only then do the battery containers go in.

So acreage is never just acreage. A long, thin lot with the right square footage can fail once the buffers go around it.

NFPA 855 spacing and setbacks

The national fire standard for these systems, NFPA 855, sorts outdoor installations by distance. Indiana's planning handout sums it up this way. A system 100 feet or more from property lines, roads and structures counts as remote and skips the added spacing rules. Closer than that, it needs an additional 10 feet of setback. That can drop to 3 feet if the system has fire-rated barriers, fire test data and fire-rated outer walls, and the local authority approves.

New York's fire code, printed in NYSERDA's guidebook for local governments, uses the same structure. More than 100 feet from "buildings, lot lines, public ways" counts as remote. Anything closer needs at least 10 feet of clearance from them.

Westwood's engineers give a warning: "even small increases in spacing can lead to large impacts on the layout or the total energy storage capacity." On a small parcel, the setback line can decide how many megawatt hours fit.

Fire access and water

Indiana's handout says access roads must be wide enough and built to carry construction, maintenance and emergency vehicles. New York's model local law asks for combustible vegetation to be cleared within 10 feet of each side of the system.

Water is the one people forget. Westwood notes that many fire officials require a nearby water source for firefighting during construction and operation. In town that can mean a new hydrant. Out in the country it can mean a tank or a well, plus the power to run it.

Flood, slope and ground

Glint Solar's screen looks for slopes under 5% and no overlap with wetlands, flood zones or unstable soil. Indiana sends projects in floodways to its Department of Natural Resources for review. The landowner version is simpler. That same landowner site tells owners their land might work if they have "at least five acres of flat land" outside a floodplain.

That last line is worth knowing. Owners who have read it often screen themselves out, or in, before you ever write to them.

Zoning, and the moratorium you didn't see coming

Indiana's handout says energy projects are typically allowed in agricultural, commercial or industrial zones "with special exemptions." Glint Solar warns that battery projects are often treated differently from solar and may be classed as industrial or hazardous infrastructure.

Then there are moratoria. The Town of Plattsburgh in New York adopted a twelve month moratorium on battery storage applications running from March 20, 2025 to March 20, 2026. The law says four local fire departments wrote asking for it. During that year, no town board could consider a new battery application filed after the law passed.

One line in that law deserves a developer's attention: "Applications filed prior to the adoption of this Local Law by the Town Board shall not be affected." Projects with an application already in were left alone. That's a timing criterion, and it runs through site control. You can't apply on land you don't control.

The neighbors

Most screens treat neighbors as a buffer. The rules treat them as people who can sign.

NYSERDA's model local law sets a noise limit, a bracketed 60 dBA that each town fills in, measured at the outside wall of any non-participating residence. It defines a participating property as the host parcel or any property under an agreement that pays its owner. That holds "regardless of whether any part of a battery energy storage system is constructed on the property." The same model law has applicants mail hearing notices to landowners within 200 feet of the site.

Michigan's state siting law works the same way. A law firm summary of Public Act 233 says storage facilities face minimum setbacks from homes on nonparticipating properties and from nonparticipating property lines. Setbacks are measured from the perimeter fence. Sound is capped at 55 average hourly decibels.

Read those together. Where the rules work like this, a neighbor who signs an agreement stops being the noise and setback problem and becomes part of the project. The parcel next door can matter almost as much as the one the pad sits on.

What the screen leaves you with

Run all seven and you don't get a county of options. You get a short run of parcels around one substation, and a neighbor or two you may need as well.

The checklists that rank for this search barely mention the people behind those parcels. Glint Solar lists "complex or unclear land ownership" as a red flag, and moves on.

That red flag is common on storage lists. The parcels are small, close to roads and substations, and often owned by someone other than a farm family. The owner of record can be an LLC whose mail goes to a registered agent, or an estate after the owner died. The questions those owners ask once they do answer are their own subject, and we covered them in what battery storage landowners ask.

The step after the screen

A solar list can lose a few owners to silence and still fill a project. A storage short list can't. When eight parcels pass and the owner of the best one never sees your letter, your choices are the second best parcel or a different substation.

And every week of silence costs more on storage than it looks. The queue fills. A town board can schedule a moratorium hearing. Another developer is drawing the same circle around the same substation.

So the last criterion isn't on any GIS layer. Can your team reach the person who signs for each parcel on the short list, quickly, and hear back?

Most can't, through mail alone. The owner of record is a company, or dead, or living somewhere else, and the letter goes to an address nobody reads. You don't have a land problem. You have a contact problem.

That's the part we run. We find who can actually sign each parcel on your list and email every one of them. We follow up with the quiet ones, and tell your team in seconds when an owner wants to talk. Your team takes the call and signs. On one campaign for a developer in Georgia, 1 in 9 parcels wanted to talk about a lease once their owners were reached this way.

If your screen has left you with a short list and no answers, send us the list.
