A fight over who pays to connect batteries to the grid is stalling New York City's battery storage buildout, and it comes down to a fee Con Edison charges developers to upgrade substations and feeders before a battery project can plug in.
Con Edison says the upgrades are necessary and the cost has to land somewhere. Developers say the fee — sometimes running into the tens of millions for a single site — makes projects unbuildable, and several battery storage proposals in the city have stalled or been scrapped over exactly this dispute, according to reporting by Canary Media that cited developers and grid officials tracking the standoff.
Here's why a GC or electrical sub should care even if you've never touched a battery job: this is the same interconnection fight that slows solar, EV charging depots, and any large load addition to the grid. The state's utilities regulator, the Public Service Commission, sets the rules Con Edison operates under for who pays for what upgrade — and that docket is where this eventually gets decided, not in a press release.
If you're bidding electrical or site work tied to a battery storage project anywhere in the five boroughs, get the interconnection cost estimate in writing before you price anything else. That number, not the battery equipment itself, is increasingly the line item that kills or saves the schedule.
The Public Service Commission's interconnection proceedings are public record and open for comment — track filings at the PSC's Department of Public Service portal for any case affecting your project's utility territory before you commit estimating hours.
