Parkchester and Fresh Kills Lead Con Ed Interconnection Queue

Out of 218 Interconnection Requests submitted across the 5 boroughs in 2025, over 20% come at just 2 Substations: Parkchester 2 and Fresh Kills,

In total, these substations show the most activity across all dimensions: New Requests, Total Active Requests, and Projects in Development:

Parkchester 2

• 33 Active Interconnection Requests

• 24 New Requests in 2025

• 9 Projects in Development

Fresh Kills

• 56 Active Interconnection Requests

• 21 New Requests in 2025

• 10 Projects in Development

Similar to the trends we see in the broader Con Ed Interconnection Queue, the majority of activity is dominated by a small handful of Developers, including Orenda (17 Active Requests at Parkchester 2; 17 at Fresh Kills) and NineDot (8 Active at Parkchester 2 and 4 at Fresh Kills).

The ultimate question when evaluating queue data alone is: what is actually getting built in these areas?

While Orenda has a total of 34 active requests across these 2 substations, they only have 2 projects in development, both at Parkchester.

Meanwhile, NineDot is actively developing 4 projects at Parkchester and 1 projects at Fresh Kills, meaning ~85% of their active interconnection requests are making substantial progress.

Takeaways

Understanding What’s in the Queue

First and foremost, the biggest challenge with the data provided in the standard Interconnection Queue is that it lacks the visibility needed to truly understand how the NYC battery storage market is progressing.

Over the last 2 years, Parkchester and Fresh Kills combined to account for 16.5% of all new interconnection requests (111 out of 662), 65% of which are still active.

But the queue is full of data that needs to be parsed through further to understand the likelihood that interconnection activity leads to operational projects. For example, New Leaf has submitted a total of 34 requests to these substations over the last 2 years; however, 55% have since been withdrawn and TomorrowIQ detects only 1 project in active development (Chelsea Road at Fresh Kills).

Similarly, Orenda shows tremendous interconnection activity with 46 requests to Parkchester 2 and Fresh Kills over the past 2 years - and while only 30% have been withdrawn, 2 projects in development across these 32 request demonstrates a low conversion rate.

Yet again, NineDot seems to be the bright spot here with just 9 interconnection total requests in these locations over the same time period and 5 projects actively being developed.

Impact of Con Ed Marginal Cost Study

We continue to monitor data across both the Interconnection Queue and Active Project Tracking to determine how Con Ed’s marginal cost estimates will dictate Developer’s market development strategy. In other words, will Developers go to areas with the highest marginal cost to capture greater, potential upside?

If we look at the estimates across Parkchester 2 and Fresh Kills, we see slightly different stories.

Parkchester 2 is set to see a 10 year marginal cost increase of 290% - from $40/kW in 2025 to $156/kW in 2034 - ranking it third of all substations in expected increases, behind only Parkchester 1 and Glendale.

Meanwhile, Fresh Kills ranks 10 on the list with an anticipated 10 year marginal cost increase of 165%, roughly on par with all substations ranking below it despite having the second most year-to-date interconnection requests, behind only Parkchester 2.

This further highlights the complexity for Developers to pinpoint the right market development strategy in New York, attempting to optimize revenue on a 10, 20, or 30 year time horizon with limited data available, while simultaneously keeping viability of development top of mind when navigating zoning, permitting, moratoriums and other on-the-ground complexities.
