A zero peak leaves headroom equal to the bank rating.

The first three banks have positive March peaks and unchanged ratings. Rensselaer’s headroom is unchanged between refreshes. Treat a National Grid zero-peak margin as equipment rating until the utility confirms how to interpret it.

Across the archived files, of 78 February zero-peak banks, 61 gained positive peaks and 17 stayed at zero.

Record selection

The four nearest National Grid records are shown. Distance is measured from the saved address match to each bank’s combined feeder-line centroid; National Grid identifies the supplying equipment.

Source record

Utility refresh dates: February 24 and March 25, 2026. Archive collections: March 12 and April 1, 2026. Values use the sub_load_capacity_headroom field and are rounded to three decimals. The portal guide describes electrification estimates for transport and heating.

Utility inquiry sheet

Each question follows a specific evidence issue. A utility will ask for the parcel boundary and proposed operating profile to identify the relevant equipment.

Smith Boulevard

700 Smith Boulevard
Albany, NY 12202
National Grid

“Which bank would supply the Smith Boulevard parcel, and how should its electrification headroom be applied to the proposed industrial use? The nearest Trinity record has a zero February peak and a positive March peak. Please confirm the applicable record and source date.”

Goshen

39 Police Drive
Goshen, NY 10924
O&R

“For the Police Drive parcel, which bank would supply the site, and what loading limit applies with one transformer out of service?”

The property listing names O&R; the contingency limit remains a utility question.

Neelytown

230 Neelytown Road
Hamptonburgh, NY 12549
Central Hudson

“Can you confirm the service location for the parcel listed in Hamptonburgh and address-matched to Montgomery? Which shared transformer limit applies to its feeder-derived headroom?”

The owner’s parcel boundary would settle the Montgomery/Hamptonburgh question.

Seaview

440 Bunnell Street
Bridgeport, CT 06607
Serving utility unconfirmed

“Do you serve the Bunnell Block parcel identified in the CT DEEP listing? If so, can you provide dated equipment-level load-serving information for the proposed use?”

The brownfield listing supplies the site address; the available screen reports EV hosting capacity.
