New York's battery bottleneck is the interconnection contract

Canary Media reports that Con Edison and the storage developers connecting to its system are in what the outlet describes as an increasingly hostile dispute, and the effect is a slower buildout of a pipeline that was already hard to site in New York City.

The disagreement sits at the point where a project meets the grid, and both sides use the same term for the projects at issue—community-scale, the report's label for installations bigger than home backup units. The Canary Media account does not enumerate the specific terms under contention, which leaves the economics of the fight to be read from its output: fewer projects moving, and moving later.

It is a utility against developers as a class rather than one counterparty, and disputes that generalize like that tend to be about process—templates, timelines, cost allocations applied to everyone in a queue—instead of a single contract's fine print. A slowdown reaching an entire pipeline instead of one project fits that pattern.

This is more than a routine utility-developer spat because of what an interconnection agreement has become. Power rights, as this publication has argued, are a distinct asset class now, with queue positions, transformer slots and retrofit rights trading before electrons do. In a city where siting a battery was difficult before anyone argued about terms, the agreement that lets a battery connect moves from being an appendix to the project to being the asset the project is organized around. The barrier to storage has shifted from the cost of a battery to the right to connect one. A fight over how those agreements are granted and priced is a fight over who captures the value of the grid's remaining headroom, and however it resolves, it re-prices every project queued behind the ones in contention.

Developers already holding their rights come out ahead no matter how the principle is settled, since scarcity does the work of raising what they own, while the ones still waiting on an agreement, and the lenders underwriting them, absorb the delay. Rights acquired early in a constrained urban market are worth more after a fight than before one, because the fight is itself evidence that the supply of those rights is not expanding.

The reporting does not establish which side has the better case, and this column takes no view on that. The number to watch is how many community-scale projects clear interconnection over the next few quarters, and whether the ones that do are the ones that were already furthest along.
