Land near a substation: what battery developers need to check

Begin with what you can identify

Tell us about a nearby substation or power line if you know of one. A photo, map reference or road location can help. Do not try to infer the line’s capacity from its appearance or calculate a project size yourself.

If the property has electric service, include the utility name from the bill. If it does not, say so. The company selling electricity on a bill and the provider responsible for the physical connection can be different, so the connection provider still needs to be confirmed.

A battery has two directions of electricity flow

A battery draws power when charging and supplies power when discharging. A connection review must account for the proposed operation in both directions. The result depends on the project and the system it would connect to.

Ask which company is reviewing the connection, what stage the application has reached and what remains unknown. A filed application is not the same as a completed study or authorization to operate.

Understand the limits of maps and queue lists

Some utilities publish hosting-capacity maps showing estimates under particular assumptions. For example, New York’s Joint Utilities publish maps for storage. These are useful research tools, but they do not reserve capacity for your property.

If a developer refers to a queue position, ask what that means for this project and what work remains. A queue entry, a map color and a finished connection agreement are different pieces of information.

Ask about the route, not just the distance

The nearest straight line on a map may cross another owner’s property, a road or a sensitive area. Ask for the proposed connection route and identify any permissions or land rights still needed.

If a utility line would cross your own retained land, ask where it goes, what access is required and what activities would be restricted there. Those rights should be part of the land discussion, even if they are outside the equipment area.

Find out how unknown costs affect the land agreement

Ask whether the developer knows the likely connection work or is still waiting for studies. If costs make the project unworkable, ask what happens to the option and any rights recorded against the property.

You do not need to pay for a connection study to submit an initial inquiry. Share the location and information you already have. A later proposal should explain who is responsible for each investigation and its cost.
