Battery storage land in ComEd’s service area

Confirm the electric utility first

Use the electric delivery utility listed on a bill for the property if available. Include the parcel location as well. If there is no active service, say that rather than selecting a utility because its name is familiar.

A utility-area guide describes a connection resource, not every parcel inside a county. Your tax parcel, existing service and the project’s proposed connection point may answer different questions. An early review should identify those differences before relying on a map.

Use the storage map rather than assuming solar capacity is enough

ComEd’s hosting-capacity workshop explains separate generation, load and energy-storage maps. The storage map combines generation and load limits to consider import and export. The workshop describes the maps as snapshots and says detailed interconnection studies are required.

If a developer shows you a map result, ask which layer was used, when it was updated and where the proposed connection is. You do not need to interpret the engineering yourself. A saved location and the developer’s explanation are more useful than a screenshot without context.

Ask what the map has not settled

ComEd’s workshop describes feeder capability under conditions at the time of the map. Ask whether the information is current and which changes since that snapshot could affect the site. A result is a starting point for investigation, not a guarantee of low upgrade costs.

Ask whether anyone has submitted an application, received study results or estimated connection work for the actual layout. Clarify which costs are still unknown, who is paying to investigate them and what happens to your option if the connection is too expensive.

The line route is part of the land discussion

Ask for a drawing from the battery area to the proposed connection point. Identify roads, driveways and other parcels along that route. Do not assume the nearest visible pole is the point the utility would approve.

If cables or access would cross land you want to keep using, ask how the rights are defined. Explain where farm equipment, deliveries or future building work must still fit. Your lease discussion should include those areas as well as the equipment pad.

Keep the local approval path on the checklist

The utility connection does not decide whether the land use is allowed. Identify whether a county, city or village handles the parcel and ask about the actual battery proposal. The DuPage and Will guides explain local records that may be useful if your land is there.

For a larger or differently connected project, ask which process applies rather than carrying over conclusions from a distribution map. A different connection point or operating plan can change what needs to be investigated.

Start without technical measurements

Send Sunland the location and your contact details. Add the utility, parcel number and the area you could consider if known. You do not need to choose megawatts or calculate charging limits.

If a developer has already provided a map or proposal, say so. Explain what you want to learn: whether part of the land might work, how a lease compares with a sale or what the next investigation would involve. That gives the review a useful starting question.
